Brittany, stealing my friends booty call

Brittany and I graduated the same year, but it wasn't till after high school she became more than a girl I followed and jerked off to. My friend had recently started hooking up with her in secret when he got in trouble with his girlfriend. They'd hit a real rough patch recently, so my buddy was spending more time in Brittany's pussy than talking to his own girlfriend.

He told me who it was, and I've been one of her most loyal followers ever since. Brittany had it all: fun personality, pretty face, a killer ass. She loved posting thirst traps whenever she went out, and was always posting things to her stories. Over the last week or two, I've noticed she'd post an almost pitch black photo with the time stamped on it. To most of her followers it was a random message they had no way of deciphering. Lucky for me, I knew what they meant.

My friend was awful at keeping secrets. In fact this whole thing between him and Brittany was supposed to be a secret, but he said she felt so good he had to tell somebody, and it happened to be me. He would always tell me the next day when he'd hooked up with her, and it turned out that each night Brittany posted one of her cryptic photos was a night they had fucked.

I used this to my advantage, racing over to Brittany's as soon as she posted the picture to catch her coming home from another hookup. Neither her or my friend had caught on to what I was doing, hiding out of view from either of them so I could catch any last minute teasing.

Tonight I could see Brittany's head bobbing up and down over the driver's seat, giving my friend a blowjob right outside of her house. She got out of the car in a hurry, probably receiving a text from her parents asking about the noise outside. My friend sped off into the night after Brittany left the vehicle, likely heading home to cure his major case of blue balls. I stood behind for a few minutes, watching the lights turn on for a moment before shutting off again.

As expected, I had to hear about my buddies latest sexual conquest with Brittany, telling me how she was blowing him in is car when his mom called to see where he was. I thought Brittny had cut the night short, but the reality that it was my friend who ruined it somehow felt even better.

My buddy couldn't come up with a convincing lie to his mother, so she started to call him a lot more frequently when he went for his booty calls with Brittany. He said that there was still plenty of time time to fuck, but they would usually make one another cum before she went inside, and the last four nights they hadn't been able to.

This told me that Brittany was often sexually frustrated, and needed a way to release it. Playing into the frustration, I started asking my friends mom if she had heard from him because he wasn't answering my calls. Seconds later, I watched as she called her son, killing the groove the pair had just gotten into. By my count, it had been two weeks and seven hookups since Brittany had cum, and I could tell the tiny white girl was getting ****. When my friends car arrived at Brittany's house, I could see her pulling his head into her pussy, forcing him to eat her out to try and finish.

Not to be outdone, I began calling my friends mom earlier and earlier, to the point I had her calling him while they were still out fucking. He said they had almost been caught last week, Brittany forcing him to keep fucking her when he was on the phone with his mom, leading him to lay many awkward grunts and moans into his mother's ear. She grilled him when he got home, eventually convincing her he was out skateboarding with some of his friends and had just fallen when she called.

Brittany was visibly pissed, barging out of my friends car as soon as she got home, slamming it shut and walking away without so much as a glance back. First she wasn't getting off and now she's not even getting the usual creampie. The nineteen year-old was so worked up, I thought it'd be best if I tried to help her relieve some tension.
