My stepsister always teases me for being a virgin, whispering naughty things in my ear, repeatedly touching my body in a provocative way, and blatantly showing off her panties and cleavage. She's just a little devil! Of course I got a boner, and she even tried to make me get a boner! I naturally thought she was trying to seduce me, so I got serious and attacked her, pistoning hard without caring about anything! Then my slutty stepsister started cumming a lot, and she turned on and held me hard with a crab lock!
