He spanks his stepdaughter on the couch

Last night, at dawn, i heard noises in the living room, and when i approached, i saw that it was my stepdaughter fucking her boyfriend on the sofa. they were dirtying my new couch. of course, i wanted to teach my stepdaughter a lesson, but not now. i waited until the next day when we were alone. i told her what i had seen and she asked me not to tell her father. i didn't want to say anything, but she was a bad girl and i wanted to punish her. so i made her lie on my legs and spank her. i spanked her until her vagina was wet. and that's when i gave him a blowjob. it was so humid.
