The room glowed and suddenly vanished. It was dark, Roger was hot and damp, and something heavy was pressing down on him. The last word he heard Mark say was "yourself", then he heard another male voice say, "Sally, Sally, Sally, Yes, Sally!"
As Roger opened his eyes, he felt a warm rush throughout his body as he began to perspire. Something was jabbing and moving deep within him. It made him feel oddly comfortable, as if he was snuggled in front of a warm fire on a cold night. He wanted to feel it closer, but couldn't work out what was happening to his old body. He'd never felt this before. Then he recognized the face breathing heavily on him. He gasped, "Oh, Dan!" in recognition. The voice coming out of his mouth was his sister, Sally's and that face was that of her boyfriend, Dan who must be making out with her. Oh my God, he thought.
Before he could pursue that thought any further though he felt Dan's hands running all over his young body. Sally was older than him by a year, but he'd always felt very protective of her anyway and certainly had no idea she was going this far even though she was going steady with Dan - he was only Roger's age but did have a pretty pumped frame.
With that he felt Dan's soft young hands on his breasts and his whole body tensed with a splendid orgasm. He heard a scream - that must be him - then felt Dan's cock thrust even deeper into him than before and hot spurts deep within him. Dan slumped down with all his weight on top of his now nubile young female frame.
"Ready for round two?" Dan asked as he french kissed her. The tongue in Roger's mouth prevented an answer. His sister's body instinctively kissed back though, and Dan's wandering hands perfectly manipulated her body. Roger felt thoroughly stimulated but had no idea how this would work out.
