[MFM] Fucking my ex and her younger brother

I cucked my ex’s younger brother. He was always super forward and overly sexual with his older sister, my ex. She’s an absolute stunner. Brunette, blue eyes, perfect body and the most amazing ass on the planet. So I get it, he’s young and dumb and full of cum. His sister is smoking hot and kind of a slut.

But he was too forward. Smacking her ass. Trying to wrestle with her. I caught him stealing her dirty panties numerous times when we were visiting. She never took any of it seriously and played it off, pretending like it didn’t mean anything. Now I know she secretly enjoyed it. But it was pissing me off. I was getting close to a breaking point.

We go to visit one weekend and it’s early in the morning. Me and the ex had both just taken a shower and are in our room drying off. I can’t fucking resist this girl naked, so as she tries to slip on a tiny little thong I grab her up and she wraps her legs around my waist. I’m a big guy, 6 foot and 210 pounds. I’m a Marine veteran and in better shape than most. She’s tiny besides that incredible ass. So I’m just holding her there, cock throbbing against the underside of her ass, one arm around her waist and the other rubbing from her tight ass to her dripping pussy.

That’s when I see him. The little fuck is outside our door, cracked, watching. I whisper in her ear that her little fucking shithead brother is watching but she just moans and tells me to close the door and ignore it. Noooooooope.

I throw her down on the bed and stomp over to the door, ripping it open. He’s fumbling with his pants and a pair of her fucking panties muttering excuse when I grab his arm and pull him in the room. He’s a scrawny little fuck so it’s not hard. I ask him what the fuck he’s doing, he mutters some bullshit under his breath. I tell him I know about the panties and him watching us etc and he doesn’t know what to say, he says sorry it won’t happen again etc etc.

Meanwhile his sister has sat up and not covered up at all. She’s just leaning back kind of smiling and he keeps glancing at her. She’s pissing me off with this little game. So I finally snap. I say if he wants to see his sister get fucked then he can sit and fucking watch.

I grab the pair of underwear from his hand and then grab his sister by the hair. She’s insanely submissive and likes to be dominated very roughly. I tell her to open her fucking mouth and she does immediately. I stuff her panties her brother was just using to jerkoff in her mouth. Then I drag her on all fours over to where her brother is sitting and push her head into the ground, ass up. I start to spank her and pull her hair back, making her moan and squirm. I start to finger her ass and pussy, saying what a slut she is. I pull the gag out of her mouth and pull her up and sit her on my lap on the edge of the bed. I tell her to rind on my cock and then look at her brother. I make her tell him that she’s a slut. That she loves when I fuck her in the ass.

I proceeded to show him exactly how much she loves getting fucked in the ass. By the end I was calmer, and she babies him. She begged me to let him have something at least, so she finally took his pants off, her legs spread, and jerked her 19 year old brother off until he came all over her pussy. Which I made him lick up until she came again.

Over the next year and a half things escalated pretty rapidly. It was a great time.
