Finished

Ashley held her husband down, using his own hands to clutch at her former breasts, fingers digging into the deliciously ripe tits. She drove her new cock deep into her warm cunt, staring down at herself to watch her slide in and out of that slick hole. Desire was so much more immediate in her husband’s body. Tension built within her balls, urging her to thrust deeper, faster.
Ashley plunged into her husband, watching him wiggle on the bed, eyes rolled back with pleasure, his entire body bouncing with each thrust.
“Fuck, I’m gonna cum,” Ashley moaned.
Her husband’s eyes shot open. “Pull out!”
“No!” Ashley grunted, thrusting in deep and releasing herself.
The tension burst, giving way to sweet relief as she emptied herself into her former body, cock spasming inside her husband’s wet hole. He was pinned beneath her, little mouth opened in shock, brow creased in confusion and fear. Ashley finished with one final thrust, driving herself in to the hilt as her cock finished throbbing. She pulled out, new dick slick with their mingled juices.
“W-we’re stuck like this,” her husband said, lip quivering.
“We are,” Ashley nodded.
Realization dawned. “You did this on purpose!”
She had. They both knew they were playing with fire by swapping bodies and having sex, but her husband had no idea she was planning to steal his life.
“I’ll be wearing the pants from now on,” Ashley said. “So you better get used to it.”
