Compulsion

They continued to stand in the doorway, kissing madly and masturbating each other until Shelly groaned, "Take me to bed, we've gone this far, we might as well go the distance. I want you in me."

Jim took in a big breath and pulled back from her, "That what you really want Shelly? I've been dying to touch you and this was all quite beautiful, but that's as far as we go. If this happens again, there will be no stopping for conscience, I'll fuck you."

Shelly stepped backward, pulling away from him, embarrassed and surprised at his rejection. Tears welled up in her eyes and her face reddened as she turned and raced to her bedroom.

Jim grabbed a big towel and headed for the beach. He was not happy. He should have been gentler; he had encouraged her for days now and should have expected something like this to happen. But if he did screw her, it would have to be something more than a heat of the moment decision on her part. The cool water did wonders for his erection as he paddled out to the reef. Jim was fatalistic and soon back in normal mode, shit happens and one cannot undo anything in life.

Shelly was easy and relaxed and smiled at him as he returned to the condo. She just said, "Wow, that was close," and giggled. She felt relieved now, it had been exciting, her hunger for the young man assuaged to some degree, the exchange had served a purpose. She made lunch and they sat comfortably out on the lanai to eat together. Jim's eyes continued to roam her body, smiling as he took in her breasts swinging in the halter-top as she moved.

She said, "What are you grinning about?" She learned once again that with Jim you don't ask a question unless you really want to hear his answer.

He grinned back at her, "Just reminding myself that I had those two beauties free and bare, and I didn't even feel or suck them."

She giggled, "I think your mind was elsewhere, as was mine."

He turned serious momentarily, "Just so you know Shelly, if anything like that happens again, it will not end were it did this morning."

She said, "I know that. And if it happens again, it will be because I want the rest of it. Now, take me for a beach walk. I love the feel of the warm sand and water on my feet, but don't like to go alone. Come with me."

The rest of the day was relaxed, Maui fashion, no apparent fallout from their hot embrace. But to say that the attraction was over would be untrue. They had a beautiful dinner in a beach restaurant with Bill that night. They watched the sun disappear into the ocean as the palm trees rustled with the late evening breeze and a light surf gurgled on the beach. When Bill excused himself for a few minutes to go to the men's room, their knees met under the table, fingertips engaged erotically and their eyes locked in a virtual embrace.

Later that evening, Bill was reading in bed when Shelly came out of the bathroom. He looked up as she dropped her nightie to the floor. It was obvious what she wanted. Bill said, "God baby, you'll wear me out, I only have so many bullets in my gun now, I'm getting older you know." Shelly climbed into bed and pressed herself to him, reaching down for his cock.

Bill pulled his head back a bit until he could see her entire face and eyes. "What's up babe? I've never seen you so amped up for sex. I don't suppose it is that young stud staying with us? I see the interplay between the two of you. Admit it, he is turning you on."

"Oh Bill," Shelly protested, "of course not, you know how much you mean to me, I would never do anything to push us apart. I want you for the rest of my life."

"I know babe, you might not do it, but you do want to do it. There is very little difference. Was it Jimmy Carter who admitted to 'lusting in his heart'? Face it, you have an itch that you want scratched, and sex with me is not helping. Maybe you better let him scratch it for you."

Shelly pushed up on her elbows to peer into her husband's eyes. "I can't believe that you just said that! I admit, I flirt with him and he looks at me like he wants to eat me. But that's all there is to it." She had decided to admit only so much about her interest in Jim; their exchange earlier that day would remain a secret with attached guilt.

Bill shrugged, "Whatever, suit yourself. But hear this and take it however you wish. I just swallowed a sleeping pill, you know how I react to those, I'll be bye-byes until morning." Bill had always been a sound sleeper and particularly here on Maui. She had seldom known him to take one of her sleeping pills and knew it would be lights out for him until morning.

She released his cock and rolled away from him. "God Bill, whatever do you think of me?"

He pulled her to him and kissed her softly. "I think that you are beautiful and desirable and I love you and plan to keep you forever, no matter what happens."

Shelly's heart was pounding, both enraged at her husband's comments and thrilled at the apparent permission to live out her dreams. Her mind was made up despite her denials to herself and to her husband. She wanted to feel that young man on her and in her. And then she thought, 'what if he turns me down?'

Jim was reading an E-book in bed; sitting with his back against the bed-board clad only his undershorts. His packsack was open on the floor beside him, all ready to leave early tomorrow for home. He had called Clare to see if her hubby had left town again. She had responded, "Yeah babe, he's gone. Why? Got a problem that I can help you with?" Jim said, "Oh yes, big problem, might be too big for you to handle." She responded, "Ah damn, hurry home babe. I love solving that sort of big problem. I'll let myself in and wait for you in bed."

He looked up as the folding door was pushed open with Shelly standing hesitantly in the opening. She wore a sheer nightie, her naked body highlighted by pink nipples and the shadow of her bush. "Can I come in?" she pleaded.

Jim was surprised to see her but remained in control and said, "Sure, come in, as long as you know what will happen with you dressed like that."

Shelly was emboldened by the lump quickly forming in his shorts and smiled at him, "Oh yes, I recall your warning." The only movement in his body was in his shorts. She stood close beside him.

He reached out and teased a nipple through the nightie and asked, "What warning was that?"

She glanced down at his fully erect cock now tenting his shorts and edged closer to him. "The one where you warned me that you would fuck me if I came close to you again." She could barely speak, her throat tight with tension and desire. He squeezed a nipple as she bent down to kiss him, her hand reaching down to rub his cock, the head of which was pushing out from under his waist band.

"Take it off," he ordered, "let me play a little."

Shelly quickly pulled her nightie over her head and tossed it to one side. Her tits dropped down from under the nightie as she returned to standing mode beside her very horny stepson.

He lifted one breast up and kissed and licked underneath it and along the crease with her chest, and then repeated it with the other. She fed him a nipple to lick and tease before he clasped it and sucked it hard into his mouth. She pulled that nipple free and tucked the other one between his lips.

"Spread a little Shelly," Jim said as he slipped one hand between her legs and moved it upwards between her silken thighs.

"Oh God," Shelly moaned as the edge of his hand engaged her swollen pussy lips, gently at first, sliding slowly back and forth along the length of her slit. He moved his thumb to rub her mound and tease her clit as she rubbed her wet pussy on the edge of his thick miner's hand. She spread more as one finger found its way between her lips and into her entry hole.

Shelly braced herself on his shoulders, legs spread widely as he sucked her nipples and finger fucked her in an ever more desperate fashion. She whimpered and raised one foot to the bed to spread and allow two thick strong fingers to penetrate deep into her pussy, the heel of his hand crushing her mound. She struggled to maintain her balance. God, she was going to come, she wanted more than fingers in her, but she could not stop him.

He sensed that she was right on the edge and quickly moved her to one side and stood up. "Sit there," he ordered as he stood to drop his shorts to the floor. Shelly positioned herself on the side of the bed with her feet on the floor. His cock was in front of her face, so hard it was bowed upwards like a boomerang. The shaft was throbbing and pulsing. She made a move to pull it to her mouth, but Jim pushed her to her back and moved between her legs.

She raised her ass up to receive him as he grasped his cock and circled her wet slit with his purple knob. She raised her knees to clamp against his hips and then shut her eyes to concentrate on the feeling of his cock pushing relentlessly inside her. This was followed by a few intermittent strokes as they accustomed to each other's bodies. He lifted her legs up over his shoulders while still buried inside her. His eyes burned into hers as he loomed over her, he thrust into her three times without pause, waited, then five more before saying, "I warned you Shelly, I warned you." As he paused Shelly's used her fingers to spread her pussy lips as he ground against her.

He fucked her steadily until he got off, apparently ignoring her needs, although she had no idea what her needs were except to be pounded like a drum. His cock slipped out of her pussy on the third spurt of cum and shot a stream up her belly to her tits, before he shoved it back into her. Shelly grasped his arms to brace for his thrusts as he continued to stroke her.

He lifted her and rolled to his back with Shelly on top of him, settling down on her knees each side of his hips, his cock still buried in her. She leaned ahead, her eyes closed, her tits dangling over his face as she rode his cock mindlessly until her ass cheeks began to constrict and tighten. She flattened down on top of him with her legs thrust down between his, pressing sideways for leverage as she ground her pussy at him, twisting and turning around his still stiff shaft. She froze there after getting off, clamped against him, his hands full of her cramping ass cheeks, tugging and pulling them apart.

"Leave it in me as long as you can," Shelly groaned, "that's the best feeling in the world." He rolled them to their sides facing each other, her upper leg hooked over his hip, his lithe hard body still grinding her, not able to get enough of the feel of her. They slow fucked, his cock staying hard enough to keep working into her. They kissed and rubbed their bodies on each other. They took turns, he running his cock in and out while she remained passive, and then the reverse, she thrusting at him as his hand clasped one ass cheek and his fingertips teased the crease and her butt hole.

She tried to mount him again, pushing him back, wanting to ride him as before. But he held her still, "Let's get off like this, love the feel of your naked body wrapped around me." He took over and began to slide his cock in and out relentlessly, his hip providing the driving force as he hooked an arm under her upper leg to spread her wider. His cock was back at full hardness as he stroked her without pause. She surrendered to him, allowing him to use her and pleasure himself with her, wantonly open to him for anything he wished. Then he was back on top of her, fucking madly. She must have passed out as she came again. All she could feel was his hot cream spurting inside of her once more.

They lay there quietly, his cock finally squeezed out of her pulsing pussy, sliding out but still jammed against her creamy lips and bush. "My God," giggled Shelly, "I just knew it would be great, but that was beyond great. My pussy will be sore tomorrow. But it feels wonderful right now." She clamped her thighs tightly, enjoying the sensations. "What now? We're all sticky. Do we dare shower together? What if Bill got up for a leak."

Jim laid back, one arm stretched up over his head, totally relaxed and not caring one way or the other what was next. But he finally said, "Let's go to the beach with a blanket. It's dark as hell, nobody up anywhere. We can wash off in the ocean and lay on the sand in our robes."

"And then what?"

"We can do anything we want can't we? Have you ever been screwed on a beach like in the movies? I haven't, but would love to screw you there. Are you game for it? It's safer for us than in the shower. No way you don't get fucked in the shower Shelly. Let's do it, chance of a lifetime." He was as serious as he was kidding, but it would be her call.

Shelly rolled against him, kissed his shoulders and upper arms and then found his mouth with a searching tongue. A lingering hot kiss was followed by, "Yes, let's do it. Ever had a blow job on a beach?"

Jim had an early flight next morning and his father and Shelly drove him to the airport. There was no tension in the car; if Bill suspected what they had done the previous night, he did not show it. Bill parked the car giving Shelly and Jim a few minutes alone after he checked in for his flight. They kissed lightly, bodies just touching. Shelly looked directly into Jim's eyes and whispered, "Any time, any place."

But Jim was already thinking about Clare waiting in bed for him and simply smiled and gave her a peck on the cheek. Bill arrived, they embraced and Bill said, "Come back soon son, you're welcome anytime. Right Shelly?"
