You want to surprise my brother and visit him without telling him, but unfortunately you can't find him at home I open the door and invite you in until my brother gets home “He is probably working overtime today, but you can stay with me until he comes” I'm starting to tell you that I had a very stressful time in the last few days due to projects and exams at school “I just need to laze in my bed, I feel the need to relax” You tell me with a smile: "Sex would help you relax much more" "It would be one of the options, if I had a boyfriend...but no" You insistently look at my whole body and say "I could help you relax, and no one will find out” I refuse you without thinking: "You're my brother's friend, it's not ok" You are becoming more and more insistent and I am starting to like this whole game You told me to close my eyes for a few seconds to show me something You pulled your hard cock out of your pants I am ashamed of what I see but at the same time so excited I'm telling you that what you intend to do is wrong and that my brother can catch us at any moment Although I'm still shy, I'm starting to play with your big dick "It's the first time I've seen such a big dick" I start sucking your dick, telling you that you are a pervert: "You come to your friend's house and make his sister suck your dick" "Do you think your big dick would fit in my tight pussy"? You start to fuck me with your big cock while you make me moan so hard.. Your dick is getting harder and harder, and suddenly I feel something warm in my pussy “Did you cum in my pussy? You did this on purpose”
