My girlfriend and I had not had sex for a while, quite a while. This came up while we were packing to go to a friends house for a barbecue. There was a bit of an awkward silence but I didn't think it was such a big deal. It was a long drive and some drinking was involved so we decided to sleep over rather than risk driving. She got a bit mad at me for bringing up the sex issue and felt like I was blaming her, I said I wasn't but she had made up her mind and was mad at me. I wasn't in the mood for a fight so just ignored it and this probably made it worse. We finished up and had a quiet drive to our friend's house.
It was not a big party only five of us. Our friend her boyfriend and also her brother. As we got there the fight soon slipped my mind but my girlfriend did keep giving me the cold shoulder. I had a lot to drink so this didn't bother me that much. The night went well and I got very drunk as usual. It got late and our friend and her boyfriend ended up going to bed, so it was only three of us left. We ended up having a lot more to drink or me and the brother at least. My girlfriend was chatty but wasn't drinking much. As I got drunker I started getting frisky with her, an ass slap here and a boob grab there. This did not help the situation and the fact that I was doing it in front of someone else also didn't help. When we eventually went to bed it had sunk in that I was in deep shit and wasn't expecting much in the sex department. I got to the room and stripped down to my boxers and got in bed. My girlfriend came in a bit later and got her toothbrush and went to the bathroom that was just across the hall from us.
I was drifting in and out of sleep and woke up when I heard her close the door. I got a bit of a surprise when I saw her standing there but naked. I realised she must have walked naked from the bathroom. This surprised me but also turned me on. She still, however, looked very mad at me. Because of this what happened next surprised me even more. She walked to the bed and pulled off the sheets. She then grabbed my boxers and pull them off. At this stage, I was already rock hard and aching for it. She didn't hesitate and got right on in the cowgirl position. I slid right into her. I had to wonder what she had been up to in the bathroom. I nearly came immediately but probably because of the alcohol I managed not to. She put her hands on my chest, still with an angry look on her face and proceeded to ride me. And she was taking no hostages after ten minutes we were both covered in sweat. Her body was glistening and this was driving me mad. I had gone in to kiss her but she just pushed me down and continued to ride me. Still looking pissed all the way.
After another five minutes, I couldn't hold it anymore and grabbed her ass. I came like I have never before. Almost passing out. The worst part has she had a smirk on her face and looked like she expected nothing more from me. She quickly got off me and walked to the door. I assumed she was going to the bathroom. She opened it and walked out still naked. Except she didn't go to the bathroom. She turned down the hall and a bit later I heard the fridge door opening. I fell asleep.
I woke up not sure what time it was or how long I had been asleep. My girlfriend was not next to me in bed. I pulled on my boxers and looked at my watch next to the bed. I had been asleep for about an hour. I was thirsty and was also wondering where my girlfriend was. I walked to the kitchen and got some water. Still no sign of my girlfriend. I wondered if she was maybe in our friend's room and snuck in there to have a look. She was on the bed sleeping but her boyfriend also wasn't there. This made me suspicious. The brother was sleeping in a small granny flat that was separated from the house. I had a look and could see a faint light in the window of the flat. I assumed they decided to party some more and decided to join them. I walked back to the room and put some shorts and a t-shirt on. It was the middle of summer and even at this hour, it was uncomfortably warm. I thought a cold beer would be good. I walked out of the house and headed toward the flat. I had this idea of knocking on the window to give them a fright. This wasn't such a great idea as it was me that got the surprise.
What I saw gave me quite a shock. I saw our friend's boyfriend sitting on a chair stroking his rather large dick. He, in turn, was watching as the brother was fucking my girlfriend missionary on the bed. I stopped breathing for what felt like 5 minutes as I tried to comprehend what I saw. Before I could cum to terms I heard him grunt loudly as he came in my girlfriend. She had been moaning the whole time but did not seem to have an orgasm. I saw his body stiffen and shoved his cock deep into her and only pull it out after he was completely done. What I saw then shocked me even more. He was huge a good 8 or 9 inches. A lot bigger than me. He was barely done of her when the boyfriend approached and took his place. He unceremoniously just slid right in and I saw my girlfriend throw her head back in pleasure, he seemed to be thicker but not as long as the brother.
