My step-brother is watching anime and I come over and remind him how we used to watch Demon Slayer together a lot and how I miss it, and he then tells me to sit down and watch it with him, and I say yes because I just finished tutoring and I don't want to work anymore today, so I watch it with him, but it's really hot and so I take off my shirt, and he looks at me like it's weird, but it's okay because he's my step-brother and he doesn't have to worry about it, and then I tell him that I'm his older step-sister and ask if he's been behaving himself and he says no, I'm shocked, and he starts running his hands over my breasts and wants something from me and I ask him to keep it a secret and not tell his girlfriend, and he agrees with me. So I show off for him while he runs his hands over me. So I start sucking his dick and I sit on his dick while he watches anime, and then we change positions and he fucks me leaning on the couch, and very hard, and I ask for it harder and harder, he makes me so horny, and then he sits on the couch and I get on top of him and I grind a lot, and then my tits bounce a lot while I'm on top of him and he starts fucking me on top of him and cumming inside me.
