My step-sister, who was born when my parents remarried, is a super slut! When she found out I was a virgin, she got amused and started playing naughty pranks on my dick! Of course, my virgin dick was erect! But she always stopped just before I came! She wouldn't let me cum! One day, I woke up to find my step-sister straddling me while I was sleeping, taking off her pants and humping me raw! I couldn't hold it in any longer, so I forcefully thrust my hips up and inserted myself! I came inside her in no time! My step-sister was also feeling it, and it wasn't enough, so I fucked her again and again!
