It was Jon's Aunt Joan, his mother's twin sister. Jon had completely forgotten that she was coming over for the weekend. Being his mother's identical twin, Aunt Joan was just as hot as his mother. "Hey sis," she began. "Sorry to stop in early without calling, but I wanted to surprise you guys."
She took in the the scene of her nude sister and nephew, blushed heavily, then turned around in embarrassment. "Oh, I'm sorry. I didn't realize I was interrupting you guys. I could come back later if you need some privacy."
Reality had changed so not only was his mom his girlfriend, but apparently it was perfectly normal. Jon smiled for a second. "You're my bisexual girlfriend," said Jon to his aunt.
"Of course I am," said Aunt Joan, turning around after putting her purse down on the table by the door. "I was just wondering of you wanted some alone time before our little get together." She walked over, doing a runway strut, and then pulled Susan into an embrace, giving her sister a hot french kiss and squeezing her ass, causing Jon's mom to squeak in surprise. "Its just too bad that I'm not around more often. It'd be so great if our we could be a threesome all the time." She pulled her blouse apart, revealing an ice blue babydoll ensemble out of Friedrick's. "If you guys don't mind, since you two are already naked..." A quick zip and her skirt followed, revealing a matching set of thong panties and garter. "...let me get these things off and join you. I've been missing my hot nephew loving." Joan posed for a second, letting Jon take in the lingerie, then reached down and guided his hands to her, as Susan also began running her hands over her sisters body.
A sexy strip and grope later , all of their clothing now strewn about the living room, the two identical women dragged Jon to bed with them. Jon plunged into the deep end of sexual ecstasy with a grin on his face.
