I was in high school and it was the winter and me and my gf and all my friends went to this nice hotel to go swimming inside the pool. There was about 10 of us and we were in the pool and hottub. Im there with my girlfriend and my buddy is there with his gf who is friends with mine. She is very hot she has a very fat ass in her little bikini. You needed the key card to get back into the pool so my buddys gf says she needs to go to the bathroom and if she can get the card. I thought fast and said i needed to piss too so lets go together. We dont dry off and run to the bathroom cus its cold. Instead of walking in the girls room she follows me to the bathroom. She does her business and then comes out and shit gets real. We start making out and I know I didnt have long so i pulled my shorts down. She turned around and we tried to put it in her and it wouldnt fit so I had her suck on it for a little and it popped right in. Believe me when I tell you that this girl has the best ass I ever fucked this was an amazing fat ass. I almost came so I sat down on the bench and she began to ride me. I knew we needed to get back quick so I blew my massive white 17 year old load in this chick and she moaned with approval. We walk out and hop back in the hottub with our other halfs and I felt pretty bad. Now this is where it got funny. This girl i fucked, my buddy, my girlfriend and I all hop in my car when we leave the pool at like 11. I drive to this fast food place and we get some drive thru and park and eat. We start making out with our girlfriends and we fingered them. We drop them home and were talking like boys do and he asked how far i got and i told him i fingered her. He said cool i did too but i also ate her out. Now he was just eating her pussy an hour after I came inside her and he will never know. GROSS!
