[F] Hot tub slut

One time my friend invited me over to the hot tub in her apartment building. There was this guy black, tall and muscular. Once I noticed his big dick under the swim shorts, my pussy started tingling and leaking juice. We all got our swimsuits on, I had a little bikini that was pretty cheeky. We were going down the stairs and that guy walked pass me. I could feel his dick and arms brushes swiftly against my bottom. I let out a little yelp because I’m weak and can’t help myself. We started talking and got in the hot tub together.
I could clearly feel the sexual tensions between us and soon he started placing his hand on my thighs and slowly groping me underwater. He whispered in my ear “stay quiet” and slowly started rubbing my pussy. He teased me and fingered me for a solid 10 minutes and told me to sit on his lap. I could feel his boner. Again, I can’t help myself since I’m a barely legal horny slut. I can’t fight back this urge of having him right there and I hug him with my legs. I feel his hands going slowly down my ass and squeeze it hard. I slowly move my hips in circles so my pussy will rub against his dick and I could hear him moan quietly to my ear. I feel one hand moving slowly down, moving my bikini away and start to massage my clit. I lower one hand so I can do the same for him but he tells me no. “Keep it there” too many curious eyes will notice.
It was getting late, so everyone started to go inside but he told them we would be up in a minute, but just as he said that he slid his shorts to the side and his dick went straight up and hit my clit and I jumped and yelped. My friends definitely knew what was going on but there was no stopping me at that point and we fucked in the hot tub. I felt the tension built inside me as fast as he was pounding me, it was delicious and so erotic having him like this. I just let go… My legs, my hips, my chest, everything felt incredible tense when my muscles contracted at the same time as my pussy pulsated with his dick deep inside me. I collapsed on his neck still shaking. I let go of the embrace of mylegs and he just hold me there while I came to my senses again. He stroke my hair and said softly to me: “…I’m not done with you yet”. That point, I knew that he wont stop until I pass out from all the orgasms.
