My Sister's Mouth Ch. 02

I looked back at Beth, feeling my cheeks flush. We'd just admitted to having willingly entered into incestuous activity before today. For some reason, this admission felt ten-times worse than having just done it in front of someone. At least with what happened just now, we could claim heights of passion had obscured our judgment. Last nights agreed-upon affair had been planned.

"You two are something else..." Beth said, her eyes passing from my eyes, to my saliva-drenched cock, and to my sister, who was still slumped over on the floor.

Beth stood up and sat on the couch next to me, but leaning away against the arm as she digested this information. Her best friend was blowing her brother, seemingly on a regular basis. I thought about what she could do with this information. Would she tell anyone? Could she keep it to herself? She could ruin us with what she now knew.

My sister apparently had no trust issues, as her breathing indicated she had fallen asleep. I remembered she had napped yesterday after her romp with Beth, and wondered if this was a pattern. I felt the couch shake as Beth laughed softly. "Is she really asleep on the floor?" she asked me.

"I think she is," I replied. I sat forward, picking the couch cushion up and put it back in its place. I gazed at my sister's bottom-less form, before I knelt to pick her up. I placed her gently on the couch next to Beth and then sat in the loveseat, still naked, still contemplating the future.

"Beth," I finally spoke, "you can't tell anyone."

"D, relax. I'm not going to tell anyone. I think it's hot. It's different; unexpected. Society tells us this kind of thing is wrong, but I know you two love each other. We're young, experimenting with sex. I know your sister has been dying to find someone she likes and trusts to practice on, that wouldn't run their mouth. It makes sense it would be her brother; you can't tell anyone," Beth said to me calmly.

"Besides, now I can get pussy and cock all in the same location," she smiled sexily. Her words had caused my cock to stir again. She noticed, and slid off the couch carefully, trying not to wake my sister.

She crawled across the living room floor, clad only in her mint green bikini top. I could see the cheeks of her delicious ass undulate as she moved towards me, her green eyes scanning my naked form. When she reached the loveseat, she knelt in front of me, running her hands up my legs, across my stomach and chest and around my groin, not making contact with my cock or balls; just feeling my skin.

"Tell me, D, are you a virgin? Have you ever had this," she asked as she finally grabbed my hardening cock, "inside a girl?"

"No. Well, yes, but it didn't count." I said.

She laughed at my answer. "What do you mean it didn't count?"

"Well, Lindsay and I sort of did it, but we were really drunk after junior prom. I don't remember much, we woke up naked together on the floor of Karen Telly's parent's room. I still had the condom on and there wasn't anything in it so I know I didn't finish." I remembered that morning well enough. Karen had specifically said no one was allowed in her parent's room, and had found us there, naked, with beer spilled on the carpet; boy was she pissed.

"So I was your first real blowjob," she said. "How would you like me as your first real fuck?" she asked, crawling up my body, into my lap.

"I-, I dunno, I mean, I would like it. I would love it," I stammered nervously. "Would Anna be okay with it?"

"Just don't fall in love with me. Who knows, maybe she'll want some too," she whispered in my ear, her hot breath exciting me further. Fuck my sister? I thought. Could I actually do that? Would she want to? The thought of Anna in my lap in place of Beth quickly had me hard. Beth began sliding her pussy along my cock, pressing it to my belly while she shed her bikini top.

As she slid on my cock, she pulled my head into her chest, shoving her perfect little tits in my face. I took her left nipple in my mouth, giving in to her desire to be my first. I gripped her ass with both hands, and pulled her against me, sliding my erection through her nether lips, coating it in her arousal.

"I don't have any condoms," I told her.

"Shh, I'm on the pill," she whispered in my ear. She reached underneath us, grabbing my cock, stroking it a few times. Happy with its current saturation level, she aligned it with her entrance, and just hovered there with the tip just inside her.

She placed both hands on my face, and pulled me in for a tender kiss. After releasing me, she sat back and looked me in the eyes, watching my reaction as she slowly descended on my naked cock.

Having only Anna and Beth's mouths to compare it to, I didn't know what to expect; what with this being an entirely different organ and all. I was not prepared for the sensation that greeted me. It was like being gripped in a hot, wet, velvety sheath that clung to its intruder. I couldn't decide if it felt like it was welcoming me in or trying to push me back out, but it felt exquisite. She slid down the shaft, rocking her hips side to side, until she was firmly planted in my lap. Having closed my eyes, I opened them to her beautiful face just watching me through half-open eyes. The sensation of my entering her had not been lost on her either, as evident on her face.

She gave a content sigh, and leaned forward into me, forcing me to lay back in the loveseat. She kissed me again as she slid up my shaft, and back down. As she slowly rode me, she sat up, placing her hands on my shoulders. I now had a perfect view of her delectable b-cups bouncing in my face as my virginity was being taken by my sister's best friend, whom against instruction I was starting to develop feelings for. How could I not? She was gorgeous, fun, smart, and she was riding my naked cock in our family loveseat. I chalked it up to being "in lust" and would revisit my current feelings at another point time, when I wasn't balls deep inside of Beth.

As I lay there, watching her enjoy herself on me, I was thankful that I'd just come a few minutes ago. The sensation I was experiencing would have had me on the brink already. My previous orgasm had given me just enough stamina that I thought I could last long enough for her to come as well. Beth began to softly moan in my ear, placing her head on my shoulder. She kissed my neck in between moans, picking up speed. I alternated stroking her naked back, and gripping her ass as she rode me with increasing urgency.

She slowed down in to hard thrusts, as I felt her body tighten up. This is it, I thought. I'm making this sexy thing come on my cock. She hissed into my ear, digging her fingernails into my back and shoulder. Finally she slowed to a stop, and slumped against me.

"Mmmm...thank you for letting me take your v-card, Dan-O," she said coyly. "That felt great."

We just sat there for a minute, holding onto one another. Finally, she started moving again. "Your turn, big boy," she said, leaning back so I could see all of her.

I reached up to play with her nipples and cup her breasts in my hands. I played with them while she rode me at a pace that felt fantastic. She took the index and middle fingers of my right hand and put them into her mouth, sucking on them like she would my cock. This new sensation increased my arousal, pushing me towards orgasm.

I then felt a new sensation between my legs, something hot and wet on my balls. Beth's left hand had my right, holding it to her mouth, sucking on my fingers and her right hand was gripping my shoulder, so it wasn't her. I peeked around her to the larger couch, where we'd deposited my passed-out sister.

Empty...

The couch was empty, which could only mean one thing. I sat forward, clutching Beth to me, and looked around her and down to where my sister was kneeling between my legs, running her tongue along the underside of my scrotum. I watched as she reached up to Beth's ass, and pulled her cheeks apart.

"Oh my god, "Beth said. "Is that Anna?"

"Yes. We appear to have been busted, again," I said, "though she doesn't seem to mind this time."

"Ohhhmyyygodddd," Beth moaned. I couldn't see exactly what she was doing from my angle, but I could only assume Anna was tonguing her friends asshole while her cunt was stuffed full of my cock.

"Yes, yes, yes, yesssss," Beth moaned. Anna alternated between licking Beth and sucking on my balls, bringing me to orgasm in less than a minute since I'd discovered her down there.

"I'm gonna come," I told them. I noticed I'd gotten in the habit of telling them; it just came naturally.

What happened next was completely unexpected.

My sister leapt to her feet, grabbed Beth under both arms and yanked her off me like a rag doll. I watched wide-eyed as Beth fell backwards onto the floor and my sister dove on my cock.

I began my orgasm before she could get it in her mouth, the first spurt hitting her square in the face. She sucked my cock into her mouth, tasting Beth's juices on my shaft as well as my own spurting from within. She sucked every last drop out of me, pumping me with her hand, and slapping the head onto her tongue. I watched her turn into some sort of come-fiend.

"What the hell?" Beth finally said, pissed at having been dumped so rudely onto her back.

"Sorry," Anna said, now embarrassed at her behavior. "I really wanted it."

We all just laughed. As I began to jerk from the over-stimulation I was receiving from my sister still pumping my cock, she released me, and began cleaning up her face, licking her fingers clean of the come she had collected.

We didn't talk about her overpowering need to have my seed in her mouth. We just let it go and began to clean up from our activities. I'd gotten the couch wet from my swim trucks, and the loveseat had a spot from where Beth's juices had dripped down, and another from where some of my come had splattered.

Beth left soon after, as Anna still was not allowed to have guests over and our parents would be home from work soon. I went outside to do my normal Wednesday routine chore of mowing the grass in the front yard, while Anna went upstairs to shower and do whatever else girls do when confined to the house for two months.

Life is good, I said to myself as I opened the shed to get the lawnmower. As I began the mindless chore of lawn-mowing, I let my thoughts of Beth take over. I thought about her and Anna; their friendship, our new arrangement and the feelings I'd had while Beth and I had been intimate. I didn't know where she wanted to take things, but I knew that something was developing inside me, feelings I'd never had before. I couldn't decide if they were because of Beth, Anna or both of them. One thing I knew for certain was that this was definitely the start of something great.

I mowed the entire front yard with a boner-induced tent in my shorts.
