Want to know how big the cock of his half-brother

my sister tormented me. He wanted to fuck me. I tried to push it away from me, but it was impossible. Yesterday morning she appeared in my room….. I was asleep and when I woke up it was in my bed. He wanted to see the size of my cock. I tried to get it out of the room, but she gripped my penis and he removed his shorts. And the day after is coming in my bathroom and took a shower. When you exit from the bathroom, he stripped in front of me and asked me to scoparmela. I was trying to resist, but she chased me naked, and I’m excited. Then he took the opportunity to give me a blowjob. And before I could say no, she made me penetrate her.
