Repeat

Leon couldn't stop himself from bending over in his mom's body, his ass in the air. His mom couldn't stop from grabbing her son's cock, which she now owned, and sliding it into her former pussy. Leon moaned as he was fucked with his own dick, the shaft pushing apart the velvety walls of his canal and sinking deep into him. It brought a welcome warmth and a pleasure that filled him from head to toe. He cried out in his mom's throaty voice, clutching the bed, desperate and horny, as she slid his own dick deep inside him. When she finally pumped into him, filling his pussy with hot cum, the pleasure was divine. He convulsed happily around her cock, momentarily forgetting his torture.
But as soon as she emptied herself into him, the Stranger's magic switched them around and forced them to do it again. Now it was Leon back in his own body, sliding his cock deep into his mom's wet pussy as he clutched her ass, slamming against her butt cheeks with a rhythmic slapping while she moaned beneath him. He came, a blessed relief, allowing him to momentarily forget his torture as he emptied himself into his mom.
But then the Stranger's magic switched them around again.
