"Here, let me just take it off." Without waiting for a response, she untied her top and let it float away. He swallowed audibly, staring at what he could see. The water splashing around the sides of her breasts. His hands did their work, only now they became more devious; they lingered at her sides, worked lower into her back and down her arms. He put his face near her neck and breathed in the smell of her hair. He gained confidence, and started sneaking his hands around her front, reaching further down her collarbone, tracing the top of her breasts. She started to breath a bit more heavily, and his dick was tenting up his swim trunks.
He took advantage of being able to finally touch her. As he massaged down her front his arms brushed against her nipples, sending shivers up both their spines. She scooted her body against him again, just to feel him poke against her lower back. She reached back and rubbed his thighs as he wrapped his arms around her, just holding her close and breathing her in. Without thinking he kissed her neck. She tilted her head to her side, inviting more. Her hands wandered up and down his thighs. He slowly sucked on her earlobe, and humped himself slowly against her body. She moaned and arched against him.
"Oh James..." She turned around suddenly, and took his hands in hers. "I want this, but it's wrong, but oh god I want this. Maybe we shouldn't be-"
It was his turn to interrupt, and he did so by kissing her with all the passion he'd pent up for her over their lives. She opened her mouth, welcoming him with a fulfilled longing that was overwhelming. As they kissed their bodies fit together, perfectly as they had in the womb together. His hands wandered from her hair to her breasts, finally able to feel their weight in his hands. His thumbs circled her nipples frantically, and her hands wandered closer and closer to his throbbing center. He scooted himself under the water so that her hand slipped and stroked his dick. She gasped and then kissed him more fiercely and began rubbing him through his trunks. He was so overwhelmed by her touch. They were both filled with fervor of erotica. They had both fantasized about this happening since puberty, and now that it had started there was no stopping it.
James broke the kiss to place Kelly on his lap. He trailed his kisses downward, and began to suck slowly on her nipple, relishing the feel of it beneath his tongue. He switched to the other one, and she grinded against his length. Feeling it pulse almost buried inside of her, being stopped by some fabric. He moaned around her nipple, moving his tongue faster. Still holding her, he stood up, pushing himself against her, kissing her deeply. He set her down, jumped out of the hot tub, and turned around to help her out. They both laughed at their eagerness. He carried her inside with the towels. As they reached his bedroom they began to dry each other off, sensually and slowly, wanting to enjoy every second.
James slowly hooked his fingers into her bathing suit bottoms and pulled them down, sitting her down on the bed as he did. She lifted her legs up to allow him to take them completely off. He stared down and his sister's naked body, and it was glorious. He had a raging hard, visible through his swimsuit; he saw her looking at it. He didn't move though, he just wanted to take in the sight of her. She slowly reached up and started to shimmy his trunks down. Standing before her, he grew still with anticipation. As his cock sprang free in front of her face, he felt her breath on it. They were both naked now, him standing and her sitting, staring at one another's bodies.
"Are we really gonna do this?" James asks.
"Yes."
"Are you sure?"
"Yes, and no, are you?"
"I don't want to stop."
"Good."
With that said, she took him into her mouth. The sensation of feeling and seeing his twin sister sucking on his cock was almost too much for James. But he held on and road the wave. He was fascinated by her eagerness, and she was just so fucking good at it. Her tongue twirled around his head with each stroke. He ran his fingers through her golden curls, as she cupped his balls one at a time, then kneading both. Taking all of him into her mouth, so the tip of his dick bumped the back of her throat, and then again. He had to stop her or he was going to cum. He pushed her back on the bed, and spread her legs forcefully.
"I am going to make you cum first, sister. Hard. I want to taste you, and hear you scream my name."
She smiled and closed her eyes as he started trailing kisses from her mouth to her breasts to her bellybutton. Slowly he teased her, kissing her lips then her thighs, her hips started to work their way off the bed.
"Just fucking do it James, god."
He chuckled and delved in. Pursing his lips, he began to suck on her clit. She shouted out when he did, and moved her hips faster. In response he sucked faster, and slid both his thumbs inside her. Wow was she wet. His thumbs slipped right in and he worked them faster, matching his tongue strokes. Kelly was practically convulsing as he went at it. And she was indeed screaming his name. He took his fingers out and went full out on her clit. Focusing and reading her movements, knowing without knowing exactly what she wanted him to do. She was panting and humping his face, as his tongue worked overtime. He started to hum as he went and the vibrations from his lips sent her over.
"Ohmygod, James, don't stop!"
He felt her release, and shake. Watching her cum almost made him cum and he had to steady himself. He wiped his face with the sheets, and kissed her tired lips.
"That was the most beautiful thing, I wish I could have seen your face."
She laughed, and kissed his nose. "It felt fucking incredible." Then she looked at him seriously. She pushed him down on his back and climbed on top of him. Again they made that intense eye contact. Both extremely aware of what was to happen next. She gripped him in her hand, working it up and down his length. Slowly she swirled his head around her clit, moistening it. She eased it down to her entrance, where it was even wetter. When his head was placed right up against her wet opening she removed her hand. They waited, both weighing the gravity of their next action. Still looking fiercely into each other's eyes, they both thrust their hips forward at the same time. His cock slid slowly into his sister, until it was fully inserted. They both rested that way for a second, foreheads touching. Both of them couldn't believe how right it felt, how perfectly they fit together. And then James began to move. Kelly moaned out and matched his movements. They writhed with each other, savoring each moment. Kelly arched her back, allowing him to go even deeper into her. He buried his face into her breasts, as he worked his dick slowly and deeply in and out of her.
"Oh my god, Kelly, you feel so fucking good."
She squeezed his dick inside of her, and he growled. She did it again and he growled more fiercely. Once more, and he picked her up, and settled himself on top, all with his dick still deep inside of her.
He raised her arms above her head, and assaulted her lips, she responded by wrapping her legs around his waist. He pulled out slowly and shoved himself forcefully into her, going the deepest yet, almost hurting her. But she was beyond pain, and she moaned eagerly for more. Their movements grew fiercer. She scratched his back with her nails, he nibbled on her soft delicate flesh, and they screamed and moaned each other's names.
"I'm close" He managed to say through clenched teeth as he worked himself in and out of her. Amazed by the wonderful sensation of his sister gripping him. She felt their heat rising. With each inward stroke, he rode her g spot and her mind washed with pleasure. Her brother's dick is beyond hard, and she can feel it twitching inside of her. They are both so turned on by the others pleasure that they are hyper sensitive. He didn't have to say it; she knew he was close, as he knew she was. He pulled his head back to study her face, knowing she would cum when he did. He slowed his motions again to deep and slow and firm, and watched as her pleasure broke.
Her eyes opened, boring into his, and his first spasm took him. They came together, his first rope of cum shooting deep into her, and she milked him and shook beneath him. He pushed into her again, enticing a new wave of her orgasm, and she felt his thumb on her clit bestirring even more pleasure. She screamed his name and clamped down on him. His head was a fog and he shot load after load into her, muttering against her neck. Slowly they came down, both oversensitive, and breathing deeply.
"Holy shit..."
He stayed inside her until he went soft, and then fell to her side, spooning her. She let herself be enveloped by him, feeling incredibly satisfied. They feel asleep almost at once, with the same slow relaxed breathing patterns.
