Its a tossup between these two:
1) Just graduated college and was out partying with a gf, she had gotten some ecstasy and I dont know why but I took it with her (I had only ever tried pot before and didnt like it, drugs just werent my thing) anyhow it was weird fun. No matter what we did it was the coolest and best thing to be doing at the time. We got to this nightclub and I see this totally hot guy on sitting with a group of friends and I was like instantly turned on. I walked up to him grabbed his hand and pulled out to the dance floor. We danced 2 songs and went back to his group of friends. We started to make out and touching each other all over and we ended up just doing it on a couch with all these people watching us. It was the drugs but it was a wild wicked carnal time.
2) I dont like to be tied up, but I let Ron (name-changed to protect the guilty) tie me up. Ron was the largest guy I have ever been with and we had radical sex but many times my orgasms would be so powerful that I would get super-sensitive and had to stop. So anyhow Ron has me tied up in a doggy style type position and proceeds to fuck me until I keep climaxing, I am begging for him to stop it was so sensitive and painful but he just kept going at it. There was two times during the next 45 minutes that I blacked out due to the intense sensitivity/pain/feels so good thingy. The bummer about this experience was that I can get loud but I guess I was really loud during this time and the police got called. (We were in his apartment). It was pretty embarrassing being tied up and naked with the police there, but they figured out pretty quickly what was going on.
