The Lab Accident

Martina moaned softly and reached up to wrap her arms around Jen's torso, arching her back so that she could once more press her breasts into Jen's, "Oh god, oh god," she uttered softly, occasionally switching to Italian to mumble something incoherent.

It took Kevin and Jen a few tries to get their thrusts in sync with one another as at first he kept slipping free when she would thrust forward into Martina at the same time that he was pulling back. It required his strokes to be relatively slow, given how much less cock he was working with than she was, but he adapted.

Jen basked in the dual sensation of both taking Martina's pussy and being taken from behind by Kevin. Each thrust sent waves of pleasure through her and suddenly Jen could feel subtle twinges of pleasure building just behind the sensitive ridge of the head of her cock and another just under her massive shaft in her little clit. With each stroke the pleasure began to build, encouraging her to go faster and faster, causing her to pound harder and harder into Martina who Jen was shocked to find was screaming in pleasure while Kevin tried his best to keep up the frantic pace. The pleasure built to a crescendo, the two sources of pleasure joining together as one, and then suddenly Jen felt something deep in her abdomen contract, her already huge cock swell even further, and before she could even utter a warning hot cum was traveling up her massive shaft as her pussy clamped down -hard- on Kevin's cock.

Jen's first blast of cum dumped more cum into Martina than Kevin had done the entire time they had been together. The second was so copious that Martina's flat tummy began to bulge slightly as Jen's monstrous cock acted like a stopper and kept her entire load inside the Italian woman.

While Jen's orgasm wracked her body Kevin tried with all his might to think of anything other than the two beautiful women orgasming beneath him, but no amount of baseball or math or anything else was enough to keep his orgasm away. He lasted only three more thrusts before his balls lifted and he fired off his meager load into Jen's spasming pussy. His orgasm spent he slumped forward onto Jen and Martina, panting from the exertion of trying to keep up with Jen.

Jen's orgasm continued well past her second shot of cum into Martina. In fact, it lasted for nearly a minute and dumped enough cum into Martina that her once flat stomach bulged outward from the sheer volume of Jen's load to press against Jen's muscled abdomen above her.

With an audible groan Kevin straightened, his cock quickly softening as he pulled back from Jen's soaked pussy, "That was..." he began, before realizing that he honestly had no idea how to describe what had just happened, "wow."

Jen's pussy was soaked and as Kevin pulled out a few pearly white drops of cum joined her own juices to flow down her long legs, coating her inner thighs in a slippery combination of their fluids. She straightened her arm so that she could look down at Martina only to find the woman with her eyes closed and a look of such contentment on her face that Jen was hesitant to do anything to disturb it. She looked back over her shoulder at Kevin, "You can say that again," she said with a rather dazzling smile.

The trio took a small break before resuming their activities. Jen's sexual appetite was insatiable, her cock never seemed to flag, and her pussy was always soaked and ready for Kevin, his hand, a toy, or anything else that was cock shaped. The threesome continued well into the night and only stopped when the light of drawn began to creep through the window and the sound of dorm room doors opening and closing made them all think better of getting caught in the act.

Kevin chivalrously pushed the two twin beds together to try and get enough room for Jen to rest comfortably, but her head touched the headboard while her feet extended so far past the edge of the bed that she could actually put them flat on the floor. Giving that up for a bad idea they instead pushed all the beds to the side of the room, threw the blankets onto the floor and laid down. Jen was in the middle, Kevin curled up on one side, head rested on Jen's chest while Martina pressed herself against Jen's other side and left a hand fondly on Jen's massive cock, which had finally softened so that it could lay draped over her thigh to rest with the head touching the blankets..

The three of them slept like that well into the afternoon, only to be awakened by a loud banging on the door and someone yelling, "Jen? Are you in there? Something happened at the lab!"
