On her arse

Tom pushed Genny forwards until she had to place her hands on the floor to steady herself. Sliding out from under her his cock slipped from her welcoming hole and she turned to look over her shoulder at him, questioning him with her eyes. Tom rubbed his cock along her slit before pushing it back into her, Genny's eyes rolled back into her head as a small whimper escaped her lips and she laid her cheek on the floor. Tom's cock slid into her as easily as it had exited and within a few thrusts he was pounding her pussy hard, each thrust was met with a slapping sound of skin meeting skin as ripples of flesh ran along her fat arse. Tom grabbed Genny's hips, pulling her onto his cock and making his cock enter her deeper than before. Genny's whimpers started to get louder as her orgasm washed over her, her hot, wet pussy throbbing around Tom's cock as it first gripped him tight then spasmed around him. Tom pulled her tighter to him, burying his cock in her orgasming pussy, the sensations her pussy were causing in him brought him to the edge and letting go of her he pulled his cock free. With no support Genny dropped to the floor, her orgasm having drained her, and Tom rubbed his cock between her arse cheeks, pushing them together so that they surrounded his cock like a pair of tits, before splattering his load all over her back and arse. As Tom came, a violent shudder of pleasure ripped through his body causing him to collapse on the floor next to Genny. Opening his eyes he saw that Genny had opened hers and was looking at him with a small smile on her lips

"That was the most amazing orgasm I've had in a long time" Genny whispered to him. Tom could only smile in response, his ability to speak having deserted him. Genny leant over and placed a kiss on his cheek then stood and reached for her costume, her tits swinging pendulously as her weight shifted. Tom continued to watch, that same satisfied smile on his face, as Genny stepped back into her costume, her back and arse still coated in his spunk, and blew him a kiss goodbye before walking out of the cubicle. Tom stayed where he was a little longer until the coldness of the floor overtook the warmth of his orgasm. Standing up Tom got changed into his clothes and then left the pool.
