Cheating Part 1

I was 18 had a younger girlfriend named Leah. My first gf. Despite being 4 years younger she was way more experienced sexually. I knew her 4 months before we got in a relationship. We went out on a double date with her sister Pam and a friend of mine. Leah and I made out in the backseat before I was told to drive. My friend nailed Pam in the backseat while I drove. I wanted to date Leah but she was still in love with her ex. Her older sister Pam who was 22 lived next to my best friend. In what was a party house. I spent a lot of time there working on Leah. She had me drop her off at another house. It was her ex's and she was still fucking him then she gave up trying to get him back.Few days later the house littered with kids after a party. In the middle of the night everyone crashed. Woke up to sounds of Leah getting it on with another guy. She was less than 6 foot away with her legs spread wide. The grunts and moans hurt me to the core. Despite her Sister ripping her for doing it when I was there. A few days later I'd witness Leah blowing the same guy in the middle of the night. I finally moved on. Eventually Leah started talking to me again. We'd end up in her sister's bed one night. Drunk from hanging with friends. Leah and I kissed. I remember her reaching down my pants and grabbing my cock. I was excited but couldn't get hard. So for the 1st time in my life I went down on a female. Not sure she liked it much or if I made her cum. I know she wouldn't kiss me after until I drank something. I thought I was finally in. Then the next Friday I stopped by her Sister's. I walked in and one of the guys said Leah was in the bedroom. I walked in to find her fucking one of my friends. He didn't know I liked her. Him and another friend happened to meet Pam and Leah in town. They'd talk the girls into inviting them over. I walked out of the bedroom and hear Pam getting royally fucked before leaving. It would be a few weeks before I'd stop by again. When I did Leah apologized. Within a week we'd go on a date and start seeing each other. For 2 years Leah and i were together. Her parents were good with me being over 18. I'd pick her up at her house. We would be barely out of her driveway and she'd be sucking me. Every time. She loved to blow me driving. Majority of the time I'd take her to my house. We'd go straight to the bedroom. End up in a 69. She tasted amazing. We'd fuck then I'd take her home. She'd even suck me on the way home. Her Sister picked her up once and let me know I had cum on my face. Guess I was better with my tongue now. Then one night I was horny at a friend of a friend's trailer. Pam was there but Leah was home. Pam had long flirted with me. I knew she had liked me until I began seeing her Sister. After drinking. Pam and I were alone in the living room. She had been living here with a friend and her husband. She was covered in a blanket on the couch and I sat next to her with the lights out. She was asleep. Drunk and thinking with my dick I began touching Pam's leg. Gently at first than more firm. I laid my head on her hip and found out she had only a bra and panties on. When I reached under the blanket and touched bare leg. I ran my hands up and down her legs. Eventually sliding a finger under her lace panties. I slowly ran my fingers on her pussy. Eventually working a finger inside her. She softly moaned. The blanket had pulled up. My head was now on her bare ass. With her panties up her ass. I slowly penetrated her as I kissed and licked her ass cheek. I thought the moans meant she was awake. She wasn't. I ran my tongue up her crack. Eventually Pam got up. She'd come back in the living room with a long tee shirt and crash on the floor. A few other people came in and slept. Still horny I laid down next to Pam and spooned rubbing on her.Week later a group of us went to a guy's house. I didn't Neither did Pam and I didn't go in. Alone in the backseat. She made the moves this time. Kissing me then rubbed my dick thru my pants. She was in charge. She unbuttoned my pants and had my stiff cock out. Quickly wrapping her lips on me. She was on another level as a cocksucker. Her mouth was the best I've ever had. Watching my cock disappear. She had me moaning loud. I got a handful of ass and started to play with her pussy. She stops asking if I want to eat her. Pulling her shorts off and laid back. My head was guided to her crotch. I licked her pussy good. Pam would push me back and sit on my dick. She rode me hard talking dirty. With both hands on her ass I worked a finger back up her butt. She loved it bouncing up and down. I really drove my finger deep in her ass then came inside her. She looked at me saying she needs to get off. Pushing me on my back. She lowered her creampied c**t to my face. Gripping my hair she rode my face. Feeding me my own cum. It was intense. She even made me lick her asshole. She would cum right on my face. You owed me that. A few days later I ate her bf cum from her.
