My football practice had just ended and my girlfriend’s mom picked me up and my girlfriend was also in the car. My parents were not home and I had forgotten my key so I had no way to get in. My parents were at a wedding and they said they would be gone for a while. I told my girlfriend’s mom the situation and her mom said I could stay at their house until my parents got home. We got to her house and she asked if I wanted to take a shower, since I was all sweaty and sticky. So I said sure why not. So I took a shower and I locked the bathroom but my girlfriend must have had a key to the bathroom. I got out of the shower and she was standing right there completely naked. She immediately started making out with me. It was so hot and sexy. Her sexy body with her nice curves and her decently sized tits rubbed against my body. She got down on her knees and started sucking on my dick. It was already huge at this point. She was sucking on it really hard. Her mom must of heard us and my girlfriend forgot to lock the bathroom and her mom walked in. Oh and I forgot to mention her mom was sexy. She was in her 30’s and she was wearing yoga pants and a really tight white tank top with her huge boobs popping out of the shirt. She at first was stunned and then she actually joined in. I don’t have any idea what was going through her head. She ripped off all her clothes and everyone was naked. Next thing I know there are two amazingly hot girls completely naked next to me. We walked out of the bathroom and went inside my girlfriend’s room. They both pushed me on top of her bed. My huge dick pointing straight up. My girlfriend immediately jumped on my dick and started riding it like a sexy cowgirl. With her sexy curves and all. And her mom was hanging over me with her huge boobs dangling over my head. I grabbed them and started sucking on them. Then we got up and I sat on the edge of her bed and my girlfriend leaned on my lap and told me to spank her like she did something bad. She had a really sexy ass. All curved and smooth and round. Then I lied back down and her mom got on my dick and she knew how to ride it like a cowgirl riding a bull. My girlfriend put her sexy pussy over my face and I started licking and sucking it meanwhile my hands fidgeting with her tits. Then she had forgotten her youngest daughter had gotten dropped off from daycare. She came upstairs because she heard all the noise. She was only 13 and I was 16 and my girlfriend was 16. Her mom decided she needed to learn about sex and how to suck a cock and ride one. Her daughter was wearing Yoga shorts that squeezed against her ass. And she was wearing a tight white t-shirt. Her mom taught her how to give a lap dance to a man and while doing so stripping. So her mom put her clothes back on and showed her an example and did it on me. Then her daughter tried it. Her daughter was a natural! It had to have been in the genes. It was a sexy lap dance shoving her tits in my face and spanking her ass and everything! Then we got a call from my parents and they were on their way to pick me up. And that was the end of it.
