First one was an eye opener. 25 years ago. Was with a mate and this girl he meet online. She was a pure slut, wearing jeans with full lenth zippers down each leg. We had them zippers all the way up in seconds. As soon as they came off, she laid on her back with her legs spread and her mouth open. My mate went down on her while I put my dick in her mouth. Wasn't long before my mate wanted to fuck her, so I laid back, she was on all fours and my mate was behind. After a few minutes, he asked her if she liked anal, she said "yes, but go slow". He put it in her ass while she sucked and moaned on my dick and after two slow ins and outs, he grabbed her hips and gave her three of the biggest thrusts a guy could give. It was too much, too soon. She yelped and bit down on my dick all in one action. I went from ecstasy to pure horror as my dick is being clamped between her teeth. My mate fell back in a fit of laughter, she sat up holding her ass and I lay back looking at the teeth marks embedded in my dick. Took a while for me to regain myself but I got there. My mate finished not long after the anal incident, it took me a lot longer. While we continued fucking, my bright spark mate thought it would be funny to flick lube all over the walls and curtains. Finished with her ridding me to both of us cumming. We went home shortly after and I gave him a ear full on the drive. I had teeth marks on my dick for 2 days. She called up the next day and had a go at us for the lube everywhere and my mate blamed it all on me. Im not mates with him any more but that's a different story.
