Jim and his girlfriend Jen had spent the night out in each other's bodies. It was a bit of fun and available from a specialist shop on the edge of town. The only stipulation is that you couldn't have sex. The personality would become too tied to the other person to allow transfer back out. They got back and started to kiss, before long they were half undressed and on the bed. Both of their bodies were urging they go on, Jen's hard cock was brushing Jim's soaking wet pussy. "Please don't" said Jim closing his eyes, he grabbed Jen's shirt and pulled her towards him. He felt the cock start to part his pussy lips. "Jen, I'm scared". Jenny pushed her cock deep into Jim's pussy, they ha changed places and there was no going back for either of them.
