Penny Meets the Neighbors Pt. 08

Penny took Marina's hand and led her onto the floor. Marina looked from Penny to Mark, but too scared to make a scene, she acquiesced, allowing herself to be guided into the space where Penny had been kneeling. With the room now absolutely silent, Penny knelt next to Marina and returned her mouth to Mark's cock. This time, as Penny sucked, Marina looked on from only inches away, staring intently at Mark's veiny shaft as Penny's lips, spread wide around it, slid smoothly up and down.

For a few minutes Penny ignored Marina, and with her eyes closed, focused on what she was doing. All that could be heard was the sound of Penny's slurping, and Mark's heavy breathing as Penny's sucking stimulated the sensitive nerves in his penis, causing the sensations he was feeling to grow in intensity. Finally, Penny judged the moment was right. Once again she took her mouth away from Mark's penis. With one hand grasping his shaft, she reached up with the other hand to Mark's lips and put a finger on them, saying, "Shh."

At the same time as she was forestalling Mark's resistance, Penny proffered his penis to Marina, angling the tip towards her lips, and saying quietly, and as softly as she could, "Go on."

Marina was still hesitant. Penny looked at Marina, pleading with her eyes. There was a long silence. Once again, Penny spoke, her voice barely audible, saying simply, "Please."

This time, Marina took Mark's cock in her hand, and with a final glance up at Penny's equally hesitant husband, she slowly lowered her mouth to his swollen glans. Marina began gradually; moving her lips down the shaft, slowly adapting to the unfamiliar bulk of Mark's penis as it filled her mouth. Marina hadn't got Penny's experience or practice, and she wasn't able to get her lips quite as close to the base as Penny could, but having just been a witness to the enthusiastic cock sucking of Alyssa, Niamh and Amy, Marina tried to suck as skillfully as she was able, determined to not to make a fool of herself in front of this knowledgeable crowd.

It was Marina's fear of being laughed at which finally served to break the tension. Her diligent sucking began to work its magic on Mark's cock, and soon he was groaning just as loudly as when it was Penny administering the blowjob. It soon became obvious Mark was oblivious to his former reservations, and his only care now was the sensations being produced in his cock by Marina's oral attention. In turn, the appreciative sounds Mark was making encouraged Marina, and she also forgot her earlier reluctance; as the blowjob went on, Marina's sucking became less cautious and tentative. Satisfied with the way things were turning out, Penny looked on as Marina's head bobbed up and down enthusiastically in her husband's lap.

The only trouble for Penny was, after a few minutes of watching Marina, she wanted to take a turn sucking on Mark again. She moved her mouth in close to Marina's, her lips dangerously close to where Marina was slurping on Mark's shaft. For a brief moment, Penny thought about moving in the extra inch and kissing Marina, but just as she was about the make the leap, Marina registered her presence, and with a nod of recognition, removed her mouth from Mark and asked Penny, "Do you want a go?"

Penny didn't reply, but simply took hold of Mark's shaft and resumed where she had left off earlier, sucking on him as deeply as she could, deeper than Marina was capable of. Penny knew she was showing off to Marina, but she didn't care. For a minute or so, Penny sucked gladly on Mark, once again using all her experience to provide him with the maximum of pleasure. Then, when normally she would take a break and come up for air, she instead removed her mouth and offered Mark's cock back to Marina. By now desperate for another go, Marina gladly accepted the proffered penis, and sucked until she was breathless. The two sisters continued like this, happily swapping Mark's tumescent cock between them, knowing they were putting on a display for both Mark and the circle of spectating onlookers.

At some point during this process, Penny became too impatient to wait her turn, and took Mark's balls into her mouth while Marina was swallowing his cock. The action of two mouths on his genitals at once produced a dramatic increase in the volume of Mark's groans. From then on, they continued like this, both of them pleasuring Mark at the same time, one working on his cock, the other on his balls. Doing this forced their lips closer and closer together, and eventually they succumbed, letting their lips touch as they kissed around Mark's shaft, both of them slobbering over the rock-solid eight inch rod at the same time. Penny knew if they continued much longer like this they'd abandon Mark's cock altogether, and simply kiss each other.

If Mark was going to accept Penny's new feelings for Marina he would have to see Penny kissing her eventually. Now wasn't the right time though. At this moment, Mark had abandoned his inhibitions, and was unconcerned about Marina sharing his cock with his wife. The danger was later; he might come to regret what he'd done, before Penny had introduced the idea of them sharing Marina in more ways. No, Penny had to press on, and convince Mark this was something he wanted. Besides, Penny was proud of how good a lover Mark was. Penny trusted Mark, she knew he'd be a stepping stone for Marina on the path to discovering her true desires; what she really wanted now was for Marina to experience her husband's sexual prowess.

Penny reluctantly acknowledged it was time to pull her mouth away from Mark's penis, and sat up, motioning for Marina to do the same. Marina looked on wild-eyed, animated by the thrill of performing fellatio on her sister's husband. She was clearly by disappointed by Penny's request for her to stop. Ignoring Marina, Penny took Mark's hand, saying, "Come with me," as she led him to the mattress in the center of the room.

With his mind still spinning from the blowjob he had just received, Mark willingly obeyed Penny's instruction. His compliance faltered, when instead of lying down, or getting Mark to lie down, Penny instead turned to Marina and said, "Come here and join us."

Marina looked confused, and said "What? Why?"

Penny said simply, "I want you to fuck Mark."

With her voice rising in shock, Marina replied, "Are you serious?"

"Yes," Penny said. "You need to know what it feels like to make love properly, to be really fucked. And I want Mark to be the one to show you."

Marina repeated herself, her voice more questioning this time, "Are you serious?"

"Yes," Penny reiterated, "I love you both. I want to watch Mark take you, and I want to watch you being satisfied, really truly satisfied. Right now, there is nothing I want more."

"I can't believe you're saying this Penny."

Penny's reply was firm, "Well I am. Trust me. Please, lie down Marina, I'd like to guide you."

Mark stood on the mattress, listening to this conversation, not knowing what to do. When Penny finished speaking, it was his turn to express doubt, saying, "Are you sure this is wise Penny?"

Penny's response was to kiss Mark passionately. When she pulled away from him, she looked into his eyes and said, "Please Mark, do this for me."

Neither Mark nor Marina actually said anything to Penny, but she knew from the way they looked at her they were going to do as she asked. Penny helped Marina remove her clothes. When Marina was fully naked, Penny got her to lie back on the mattress and knelt alongside her. Marina stared up at Penny, her large brown eyes questioning as she waited for Penny to make the next move. Penny turned to her husband, who had pulled off his shirt and socks, leaving him naked too, and motioned for him to kneel beside her.

Penny put her mouth to Mark's ear and whispered into it, "I want you to take Marina in the missionary position first, to get her used to your cock."

Still on his knees, Mark moved between Marina's legs and lowered his torso until he could support himself on his hands. Marina lay passively beneath Mark, still unsure how to respond to the situation. Her body was beautiful, with her soft tits splayed out on her chest, the distended nipples prominent on the large brown discs of her areolae. When Penny raised Marina's thighs and lifted her legs into the air, the glistening pink interior of Marina's wet pussy peeked out beneath the thick bush of her pubic hair. Penny reached into the space between the two bodies and took hold of Mark's cock, squeezing it between her fingers until she was satisfied with its stiffness.

When she was sure Mark was ready, Penny tugged gently at his cock, pulling his body down towards Marina's. When the head of his knob was close enough, she steered it, brushing Marina's clit with it, sending it grazing over once, then twice, until Marina's body shuddered and she let out a loud moan. Satisfied they were both ready, Penny whispered in Mark's ear once more, saying to him, "Go on."

Mark moved his cock downward to the entrance to the black hole of Marina's vagina. He pushed himself in, slowly at first, until the head was enveloped within Marina's body. She gasped, a loud, exclaimed, "OH!" which echoed around the room the moment Mark entered her. Confident now his cock was correctly aligned, Mark drove home, filling Marina in one quick movement. She gasped again, louder and more drawn out this time, as the upper side of Mark's shaft slid against the walls of her enveloping pussy. Mark sank down onto Marina until only the upper part of his body was supported by his elbows. With the rest of his body pressed close against Marina he set about raising and lowering his hips, driving his cock repeatedly in and out of her gaping wet pussy.

Marina's gasps became a succession of panted exclamations, each one pushed out of her body by Mark driving in and filling her. Mark responded to Marina's excitement by pumping into her even faster, his hips slapping into Marina's raised thighs with each stroke; making Marina's tit's wobble on her chest each time he slammed home. The circle of onlookers looked on in awe as Marina's moans became steadily louder and increasingly incoherent. Just when it looked like Marina would lose control, Mark slowed down the pace of his fucking, drawing his cock in and out of Marina so it dragged over her clit. For a fraction of a second, Marina's moaned quietened, then, as her body responded to the new stimulation, she began to moan again, this time in a wordless, high-pitched wail, which went on uninterrupted as Mark continued to grind into her.

Mark changed the pace again, this time using a rolling rhythm which circled his cock as it moved in and out of Marina. Once again the tone of Marina's moaning changed in response to the variation in the way she was being fucked. Without warning, Mark switched back to his initial fast-paced driving rhythm. From then on, Mark pounded Marina relentlessly, using her pussy mercilessly, but switching pace each time Marina appeared to be adjusting to the fucking she was receiving. Penny looked on from the side, satisfied both Mark and Marina had abandoned themselves to the intensity of the sex they were engaged in. Both had clearly forgotten their earlier inhibitions and reluctance.

When Penny judged the moment was right, she placed her hand on Mark's shoulder, and indicated he should stop. He paused, but kept his cock buried inside Marina. Below Mark, Marina gazed up at Penny quizzically, wondering why she had interrupted what, for Marina, was the best sex she had ever experienced. Finally, Penny spoke, explaining, "It's time for a change of position. Mark, you lie on your back now."

Obeying Penny's instruction, Mark rolled off Marina and lay on his back. Marina looked disappointed at Mark's penis withdrew from her vagina, but she allowed Penny to lift her, and with Penny's guidance she straddled Mark. Once again, Penny took hold of Mark's cock. This time it was thickly slathered in Marina's pussy juices. Penny pumped the shaft a couple of times, but it was already rock hard. Then, as Marina lowered her body, Penny steered the cock between her labia, nodding to Marina when she was satisfied it was correctly placed. When Penny's signal came, Marina sat down and took Mark into her body in one go.

Penny could see Marina's pussy lips yielding as her body adapted to the girth of Mark's shaft. Taking hold of Marina around the shoulders, Penny instructed her, telling Marina when to buck her hips over Mark's body, when to grind slowly, and when to slide her pussy up and down the length of Mark's penis. Penny's instructions bought Marina to the brink of cumming in a few minutes, and then kept her there, hovering on the edge for another four or five minutes. When Penny saw Mark bucking up into Marina, clearly desperate to satisfy the urges emanating from his cock, she let Marina have a free rein. For the final few minutes Marina rode Mark until she was practically screaming, while beneath her, Mark thrust upwards until he lost control of his cock and shot load after load of his creamy hot spunk up into Marina's pussy.

Mark collapsed back onto the mattress. Marina would have fallen on top of him, but Penny held her in her arms, letting her sag back onto her breasts. At first, all Marina could do was gulp air into her lungs and pant breathlessly. As she slowly recovered, she began to speak, letting loose a torrent of pent up emotions. For Marina, this was the most amazing thing in her life, an orgasm like nothing she could have ever have imagined. Penny listened indulgently, happy her sister had finally discovered how wonderful sex could be. When eventually, Marina paused for breath, Penny used her thumb and forefinger to turn Marina's face towards her.

Without saying a word, Penny leaned in and kissed Marina firmly on the lips, passionately tonguing her in an open-mouthed kiss which went on and on. From below, Mark watched, speechless.

***

When Penny and Marina's lips eventually parted, the room erupted into a babble of voices. The only person who was silent was Mark, still dumbstruck by what he had seen. The experience of fucking his sister-in-law while his wife watched on and encouraged them had been fantastic, and the resulting orgasm was incredible, one of the most amazing experiences of his life. Seeing Penny and Marina kiss so passionately afterwards was more than he could handle. The way they kissed, the way it lingered for so long, the way they looked at each other as they pulled apart. Mark could tell there was more to the kiss than excitement bought on by the sexually charged atmosphere of the party, but he found it difficult to articulate exactly what he was seeing.

For the entire time they were fucking, Mark and Marina were the sole focus of attention in the room. Mark was forced to push his thoughts regarding the kiss to one side as Penny's friends and their husbands crowded round, praising Marina for the way she had ridden Mark and congratulating her on finally getting the hard fucking she had craved for so long. Most of all, the group were gratified by the way Penny and Marina took center stage, and done everything in front them. As far as everyone in the room was concerned, Penny, Marina and Mark were now full members of the group.

For Penny the evening wasn't yet complete. The whole point of the night as far as she was concerned was to reveal her bisexual nature to Mark, and in particular her feelings for Marina. More than that, Mark had to not just know about these feelings, but accept them. She could tell Mark had noticed there was more to the kiss with Marina than he was aware of. Penny could sense the moment of truth was rapidly approaching.

As Penny sat, consumed by her worries, Alyssa came up to her. The smile on Alyssa's face told Penny trouble was coming. Alyssa sat down beside Penny and put her arm around her shoulders, "Penny! that was amazing. You must be so happy for Marina."

"Yes, I am," Penny replied, uncertain as to where this was headed.

"You know," Alyssa said, "The next thing is for Marina to fuck one of our husbands."

Penny nodded, "I'm sure she'd enjoy that."

Alyssa continued, "The thing is Penny, it was wonderful of you to help Marina like that, but it strikes me, there's one thing missing."

"What's that?" Penny asked.

"You're the only person here tonight who hasn't fucked anyone yet. That can't be right, can it Penny."

Penny didn't know what to say. It was true she was as horny as hell, but her main concern was Mark, and her goal of making him accept her bisexuality, and her relationship with Marina. She looked at Alyssa, and after thinking about it, spoke, "It isn't important. I came here tonight because I wanted to sort out my future with Mark, and let him know what I do with you."

Alyssa smiled, with a look which dismissed Penny's concerns as trivial, "Oh that! Don't worry about that. You go and get yourself laid, I'll make sure it's all sorted out."

Alyssa stood up, and in a loud, booming voice said, "Are any of you men ready for another round? Penny here needs a good seeing to."

***

Although Penny tried to act casually, Alyssa's words filled her with a short-lived bout of apprehension. Penny had never been with another man since she had married Mark, whoever she fucked now would be her first new sexual partner for nearly twenty years. She had been so focused on bringing Mark and Marina together; the fact she would be expected to have sex with another man at the party hadn't really registered. Once again, Penny was forced to hastily adapt to Alyssa's vision of how things should be. Penny reflected on the changes in her life: what would once have been unthinkable for her was now part of her new reality. It was a measure of how much her world had transformed over the past hours and days. Realizing that actually, yes, she would like to have sex, Penny resigned herself to the inevitable, and was happy when Nathan grinned and said he was ready for another go.

Although she'd have been reluctant to admit it to Alyssa, deep in the pit of her stomach, the idea of fucking the youngest man in the room gave Penny a considerable thrill. The fact he was a solidly built black man with a particularly thick cock didn't hurt matters either. For the next twenty minutes, Penny got used to the idea of being with another man by slurping on Nathan's cock, conscious of Mark's eyes on her the whole time. Then once Nathan was nice and stiff, she got on her knees and took him doggy style. They then switched positions a couple of times, mostly because Nathan wanted to play with her tits as he fucked her. Eventually, when he came, he was lying behind Penny spooning into her, reaching round to fondle her tits as he shot a thick load of cum into her.

Once she relaxed, and realized Mark now seemed comfortable with the idea of swinging and was getting off on watching her being taken by another man, Penny enjoyed the time she spent fucking Nathan. After the initial shock at how full on the party was, and then the emotional intensity of persuading Marina and Mark to come together, simply lying back and taking a pounding from a good hard cock was incredibly pleasurable. Although Mark and Marina watched every second, it helped Penny relax knowing that during the time she was with Nathan, most of the other people in the room gradually paired off and began a second round of sex; she'd been the center of attention long enough. Looking around, Penny could see Alyssa bending over in front of Rick, Amy lying on her back cheerfully taking a pounding from Jason, and Helen riding Jamie while she leant forward to let him play with her breasts.

When Nathan finally came inside her, Penny kissed him gratefully, then pulled herself to her feet and walked over to where Mark and Marina were sat talking with their heads close together. Having both cum hard recently they used the time Penny was on the floor with Nathan to recover and take stock now their earlier hesitance had evaporated. It was obvious they had been discussing something serious with each other, and when she joined them it was clear to Penny they their conversation was about coming to terms with the fact they were in-laws who'd just fucked each other. Listening to them recap their discussion, Penny was pleased to discover they were both more-or-less OK with it. Mark had obviously enjoyed himself, but was keen to stress he wasn't going to do anything behind Penny's back. Marina meanwhile was evidently grateful for the experience, but understood it was something which would have to be confined to parties like this one if it were to happen again in the future.
