I really need to tell someone this but I'm going to get in big trouble if my mother ever finds out about it. I 'raped' my mom's boyfriend. In fact I'm still 'raping' him. So you see why I can't tell anyone (but this place is anonymous so it's OK). My mom's a cougar and dresses like a slut so she brings home lots of young adults. They're still older than me by like 7 or 8 years but they're all hot as hell and shouldn't be with such a skank like my mom. I'm 18 BTW. Anyway, one of my mom's boyfriends is this really lean white guy with wavy blond hair and perfect white teeth. I love his smile, it's the prettiest thing I've ever seen. One day my mother brought him home and I could hear them fooling around upstairs in the bedroom, so I went downstairs to do my homework. I could sort of still hear them (enough, anyway), when it suddenly got quiet and my mom came down to the living room. She told me she was going into town to run some “errands” and that she would be back in a few hours. Her giggling set off an alarm in my head. About half an hour after she left, I realized that I didn't see her boyfriend leave the house. I already know what that means: a few months before this I accidentally wandered into my mom's bedroom while she was running some “errands” and found her then-boyfriend tied to the bed, gagged and blindfolded. I was SO embarrassed, but he couldn't see me and I didn't tell my mom afterwards, but I was mad at her for like a week. So, yeah. My mom's into some kinky stuff, maybe it's genetic, because I'm starting to like it too. Anyway. I knew he was up there, and I tried to ignore it, but I couldn't stop thinking about his smile. And his body (I'd never seen him naked, but I could almost imagine it). And the way his soft blond hair must feel, and a million other things that wouldn't stop bugging me. The harder I tried to ignore the thought hotter I got. My shirt started feeling sticky and my pants felt a size too tight. I went upstairs to go to my room, I mean, I meant to, but instead I was facing my mom's closed bedroom door. I put my hand on the handle, and I couldn't take it away. I just wanted to take a peek, and I was pretty sure that I could play it off as an accident if he could see me. My chest was really shuddering when I opened the door and saw him... naked, spread-eagle on the bed, glistening with sweat. When he heard the door open he struggled, but he was handcuffed to the bed with those hard steel cuffs that the police have. My mom had put something around the base of his cock to keep him from coming, and then tapped a pink bullet vibrator to the head of his cock, on the underside. It was like hypnotism. All I could hear was the buzz of the vibrator and all I could see was his throbbing cock, and then suddenly I felt like I was suffocating and had to get out of my clothes. The cold air hit me and then I noticed my panties were wet. Really wet. I started touching myself through my panties. I'm not a virgin or a prude or anything like that. It felt right and besides, he was wearing a little red or pink ballgag and a black hood so he couldn't see me. He probably even thought it was mom just teasing him. But then he made this pretty little moan through his gag and I was absolutely drenched. And I know it's wrong, but I had these dirty thoughts in my head and I didn't have a boyfriend and... Well, I climbed on top of him and pulled my panties down. He tried to struggle a little but I grabbed his cock hard and sat on it, and OH MY GOD. Between the vibrator and his throbbing cock I almost came immediately. It was like nothing I had ever felt before. That first time I only got to bounce on his cock a few times before I orgasmed and fell on top of him, all sweaty and weak and hungry. I felt sort of bad he didn't get a chance to come, but I didn't want my mom to know, so after cleaning up his cock and myself with my panties, I left and pretended like nothing happened. But that was the best orgasm I have ever had. Mom has had him over several more times since then, and whenever she leaves him alone with me I sneak up there and have him for awhile. It sounds really messed up but I've gotten a lot better at making him “suffer” by lasting longer before orgasming. It feels really good though and if he didn't like it his cock wouldn't be so hard. Plus the way he moans and begs through his gag is a real turn-on for me. His cock is probably sore by now, but I don't know if I can ever get a boyfriend like this guy so I'm going to keep using him until my mom dumps him... maybe I can blackmail him or something after that so I can keep him for myself. I hope it's soon, I really want to take my time with him and try some stuff I found on the internet with wax and clothespins. As much as fucking him tied up really makes me wet I want to do stuff to him that makes him moan and beg for me to stop. That gets me really hot. I know this sounds really, REALLY wrong (which is why it has to be anonymous), but it feels really good to get that out. Thanks!
