My girlfriend bet that her friend couldn't make me cum quickly from a blow job.

One day me, and 2 female friends were over my girlfriend's house. We were all drinking and the subject of blow jobs came up. My gf said she gives the best head. Of course I agreed. Her friend said that she is an expert and nobody is better. Next thing you know 2 drunk girls made a bet. They bet that if the friend could make me cum in under a certain amount of time, my gf would pay for drinks the next night. If I could last longer than the designated time, the friend would pay. I had no say in the matter.

They agreed that both of us should be completely naked to make it more sexy. Once again, I was not consulted about this. We all went into the kitchen. I do love getting naked in front of other people so my clothes came off quickly. The friend got naked. I stood up and she got on her knees and started getting to work. My gf warned me not to cum early or I would be in trouble.

The blow job felt amazing. I was so excited being naked in front of other people and getting head in front of my gf. She had the stopwatch going on her phone and was counting down. My dick was throbbing and I could feel myself getting close, but I still didn't bust. As we hit the time I still held back. The friend kept sucking and a few minutes later I told her I was about to cum. I blew my load on her chest and the floor. My gf cheered and gave me a big hug.

The next night we all went out and got drunk and had so much fun. Afterwards me and the gf had amazing drunk sex. She thinks she won the bet but I actually did.
