Lisa is a college senior home for her last summer break, who has never had sex before.
When she comes home late from a date and her stepfather catches her dressed like a hooker, he is absolutely furious, taking her over his knee and giving her a spanking...and more.
Mitch raised his stepdaughter's skirt up to expose her full and round ass. Just like her mother's, he thought, before he started to spank her. She winced in pain and cried out at the first few. "Please stop, Daddy, I've learned my lesson. I won't dress like a slut anymore!", Lisa breathed. But it got more subdued, though Mitch's slaps were increasing in ferocity. Soon instead of crying out, she made a new sound, softer, more needy. Mitch and Lisa both realized it together - Lisa was turned on by the pain. Mitch wasn't terribly surprised; he'd found out long ago that Lisa's mother liked to be roughed up during sex. He'd have to test out whether his stepdaughter liked it even more. Lisa, meanwhile, was coming to grips with the situation; she was over her stepfather's knee, and his spanking had turned her on more than anything she could remember. She could feel how hard her nipples were, and could feel her pussy getting wetter. She longed for him to touch her there.
By the time Mitch had finished, Lisa had started bending ass upward as much as she could as he struck her, trying to have his hand hit her clit and pussy on each strike. Mitch was amazed at how turned on she was; his hand was covered in her pussy juice. He finished, running his hand from the fresh red marks on her bare ass to her swollen pussy, dripping before him. Lisa could no longer hold her moans in and didn't even try. She trusted her stepfather implicitly, and knew he'd do the right thing with his naughty stepdaughter.
