Kristine moaned as her pleasure intensified. She undid Robert's trousers, and gently pulled down the fly. Robert's rock hard cock was straining for release, however Kristine ran her fingers along the shaft, gently teasing Robert and causing him to swell even more. The boxer shorts he was wearing could not contain him for much longer. Sensing his anguish, she pulled back the elastic of Robert's underwear and his cock sprung out like a jack in the box. Slowly, she gently stroked him up and down, admiring both the size and girth of his penis. She tasted the saltiness of his skin, as she gently took him in her mouth. Her lips closed firmly around him as she eased up and down. Her tongue danced over the sensitive tip, and his cock quivered at the sensation. Gradually she increased her pace, one hand stroking him up and down in time with her mouth, the other gently playing with his balls or stroking his perineum. Robert responded by going harder and faster with his tongue while his fingers probed inside Kristine's pussy, fingering her g-spot furiously but gently. The two of them had raised a sweat and were breathing quite hard.
After what seemed an eternity Kristine repositioned herself over Robert's cock, and gently guided him inside her, tensing her muscles to perfectly fit his massive girth. Sliding into her was like sliding into an exquisite oil. She gently rocked back and forth, feeling every inch of his cock. It took all of Robert's concentration not to come then and there. The combination of her teasing him and the sensation of sliding in and out of her had driven him to the point of release. He managed to remain in control though. Kristine removed her t-shirt and began to move more vigorously. Robert alternated between stroking her breasts with his hands and sucking on them like a babe. He could taste the sweat that cascaded down her body like a stream.
As the pace quickened again, the only sounds that could be heard was the heavy breathing and the rhythmic slapping as Robert began thrusting in time with Kristine's rocking. His balls slamming into her with increasing velocity. Kristine moaned louder, as she could feel the waves of pleasure building up inside her with each stroke. Her hips quickened, and her breathing shortened more and more. She got louder and louder until her entire body spasmed as she came, her legs quivering as she collapsed on top of Robert. Robert too could feel his climax approaching. As he passed the point of no return, he could feel a surge of fluid slowly making its way towards the tip of his penis. He thrusted harder and deeper for a few strokes before exploding inside Kristine's ever gulping pussy. His cock pulsed over and over as he filled Kristine with his seed. He let out a guttural moan as he did, before slumping back onto the couch exhausted. He stayed inside her as they both lay there on the couch, before gently falling asleep.
