Faking it

 "Oh, yes! Fuck me!" Ben said, faking desire as his mom's tits swung from his chest every time his friend, Adam, thrust in from behind.
"Oh, god…so…close," Adam grunted, eyes locked on the delicious ass of his friend's mom as he plunged into her wet hot depths.
Adam had told Ben that he couldn't stay hard if Ben didn't act into it. He'd also told Ben that fucking him numerous times while trapped in his mom's body was the only way to reverse the power of Adam's magic amulet. He'd also, also told Ben that swapping him into his own mom's body was a complete accident.
They were all lies. Adam knew what he was doing when he cast the spell. He knew that his friend's mom would never cheat on her husband, especially with one of her son's friends. So Adam had forced them to swap bodies using a magic amulet he'd found and then pretended that the only way back was copious amounts of sex with the newly swapped Ben.
Adam gripped Ben's MILF hips and grunted as he plunged deep, emptying himself into Ben's body.
"Are you swapped back now?" Adam asked when he finally finished.
"No," Ben sighed.
"Hmmm. Well, we'll try again once I've recovered."

In the finale, Andrew's only hope of escape from the mob's high-end brothel is to learn to use his wife's body to pleasure as many rich men as possible in Swapped by the Mob 3, available on Body Swap Stories, Smashwords or Amazon.
