They finish, but not without problems

"Nothing!" Owen shot back as he went back to his rhythm with Jenn, whose forearms were getting sore from the palms holding her upper body up.

"Yeah, right," came the skeptical derision, "all that clapping is jumping jacks... I'm calling management!"

Jenn's eyes widened at the prospect, but nature soon took its course as Owen started twitching his final twitches and came inside Jenn. Jenn felt Owen coming inside her, the semen smacking her cervix before filling her up like a pastry. The sensation sent her, too, over the edge, and she collapsed in pleasure, her knees buckling as her palms groped lower and lower points of the wall.

Owen soon backed up, rinsing out his foreskin and pushing the excess seepage out of his dick the best he could as Jenn turned around and sat on the floor, her arms resting listlessly on her knees as her legs were splayed open to show her pussy to the world and Owen's work seeping out of it. Jenn was too shell-shocked to worry about if Samantha was going to get a new half-sibling from this encounter.

"Well," Owen rubbed the back of his neck as he hastily finished cleaning his dick up, "I better get out of here before they come," he grabbed his towel and turned around, opening the curtain and stepping out, prepared to leave the refractory Jenn at the mercy of the gym.
