First of all, I'm really 16 years old. My father caught me sucking off my boyfriends big cock. So the next day when I got home from school, he bent me over, tied my hands on to the chair, pulled my panties down, and started spanking me hard and said he was gonna do it for a month straight. I hated it at first, but now it turns me on when he spanks me. I try not to let it show that my pussy gets wet every time his hand hits my ass but it's soooo hard to hold back. Last night, I could hear him fucking my mom to the point where she wanted him to stop, but he kept going and I couldn't help but masturbate. I want him to fuck me like that every single day and I want to eat out my mom while he fucks me.
