I chased after my little sister trying to steal our father’s money and followed her so she wouldn’t say anything

My younger sister is a spoiled girl who tries to steal from everyone whenever she can. I overheard my parents talking about it and they said that the bitch needs a strong correction, that’s why when my parents leave the house and I see her coming in to steal from my dad like she usually does, I catch her in the act and threaten to tell on her. The bitch finds herself in a tough spot with our parents, who are tired of her repetitive behavior. You accept my conditions to keep your mouth shut. To do that, I asked her to strip completely for me. At first, she refused because she felt uncomfortable since I’m her older brother, but afterward, she couldn’t help but enjoy her delicate nipples. My cock was already raging hard, so I made her suck it completely. After I could feel her delicate and small mouth around the base of my cock, I gently touched her vagina and started penetrating her slowly to cause the least possible damage. She feels pain in her pussy because she wasn’t ready for such a thick cock, but I kept fucking her until her hole got bigger and I penetrated her hard, causing her to scream in pain.
