Cum Inside Your Virgin

I know it sounds weird, but I've been reading all these sex education books. Everything sounds so interesting, but I'm a virgin. You're my step-brother and I trust you, would you help me discover all of those things? Would you play with me? I show you my body, I got all pretty for this occasion, I'm wearing shorts, a cute top and purple panties because purple is your favorite color. Can you show me your cock please? It's so BIG! I show you my titties and play with my nipples, my ass, everything, I take off my jeans and panties for you. I show you my wet panties. I'm your naughty step-sister (All of this teasing/story part lasts 5 min). Then you play with my clit and make me cum fast in like 1 min. Then you fuck me with your big dick.
