My hot and cold housemate

Since Alex lived with June, his sexy housemate, they had a strange rule : if she wanted to have sex with him, he could. But he was strictly forbidden to talk about it, even if they were just each other. Sure, June was really bitchy most of the time and Alex knew, if he had some self-esteem, he shouldn't agreed to be used like a sex toy.
But he found her so sexy during these time when she begged for him ! Like the last night when Alex had to do some work but June began undressing herself, convincing to push what he had to do later...

Little did he know, Alex wasn't really sleeping with June. Or at least, just her body. Because, just next door, lived an old granny who, sometimes, used a bodypossession spell to enjoy the youthful and beautiful June's body to have sex with her handsome and kind housemate.

Everything went well until now as, because of the rule she established and Alex's discretion, June never guessed a thing.
