We all headed to a football game 40 miles south of our town. My buddy and his sister. Amy was driving, I was in the front seat and Ted was laying in the back pretty much crashed out. Amy and I had fooled around in the past. Someone always interrupted us. As she drove her shorts were loosed enough at the crotch that I could slide my hand up her leg and into her pussy. She kept checking the rearview mirror to make sure Ted couldn't see. She put the cruise control on and hopefully when she climaxed she wouldn't crash!

Aside from being a hot day Amy was really wet and when she came it was pretty obvious. She already had a good cover story. She was going to say her water spilled. Good thinking. The next few miles she was trying to rub me off. That wasn't going to work and she gave up. We were pulling up to the game anyways. We had a cheap room overnight as we were going to party. We hit the game and between a few motel rooms we went from room to room drinking and partying. It looked like Ted and Amy were both going to end up with different people. I was a little bummed. I wanted Amy. However, she did come back to the room and she changed to go back, she was a bit drunk and stripped to her undies in front of me. She came over in front of me as I was sitting on the bed and popped her bra off. She told me she was going back to the party but we could bang off a quickie. I was okay with that. We had our fun and I knew she was going back to get with this other guy, Paul. Meh, whatever. Ted came back and asked where Amy was. I told him he could check Paul's room and we have the place to ourselves.

Ted without hesitation came over and laid on the bed beside me. I felt weird all of a sudden but my cock told me, "Yes!!" I was fucking horny. He said, "No available girls at the party." The implication was a guy will suffice. He didn't try and kiss me or anything, he just leaned his head into my shoulder as I was sitting up in bed and he dug under the waistband of my jeans. I just laid there. We could see the bulge in my pants. He popped the button on my pants, unzipped me. I pulled my pants down and let him pull my cock out of my underwear. My cock was still a bit slick from fucking his sister, not sure he'll notice. He started jerking me off then took my cock in his mouth. He muttered, "Amy" yup, he knew. Slutty horny family when you think about it. He stopped and got up and undressed. "Lets get undressed and get into bed." We did. Now his cock was out and it was rubbing my leg. He spun around so his cock was in my face. I never seriously thought I'd suck a cock but, here I go. He had a perfect cock. I loved the feel of the soft skin getting rock hard in my mouth. I'd just cum so I wasn't going to cum very quick. He on the other hand filled my mouth in minutes. I was trapped and had to swallow it. Not too bad actually. He kept sucking me but at one point he flat out asked if I would fuck him. "man, I don't know. that might be too much for me," So, he kept going and I came. He went to the bathroom and spit it out. When he came back he climbed into his own bed and spoke very little. I think he was mad and embarrassed.

Amy came back 20 mins later. Two beds. We hadn't discussed this but I kind of thought brother and sister would share the bed. Nope, she stripped and got in with me and cuddled up. Wow, this is awkward, I fucked her and her brother and we had sucked each other cocks minutes ago. Total slut evening. Amy cuddled in and whispered that things didn't work out with the other guy. I said, "So, I'm your backup plan for sex?" She said, "Well, Ted likes you. He told me." I said, "I gotta tell you something. He and I fooled around but never went all the way. Does that gross you out?" Nah, I'm good. It's just an orgasm, who cares? Was that your first time? I nodded. She told me she ate a girl once and the girl ate her. She said, "Not bad at all. Not an everyday thing." We could tell Ted was awake and she'd been playing with my cock.. I was nice and hard and regardless her brother was 4 feet away she got on top of me and my cock impaled her. This was better than the first time. The first time she just dropped her panties and I rammed it in and out for a few minutes till she came. This time she rode me and was really into it and Ted was not into the fact his sister was fucking me, his love interest. I'll have to explain to him that I like him too, but, for the time being his sister is where my heads at. I could feel her orgasm building in waves and when she finally came she didn't hold back her groans and screams. I hadn't cum so I got her up on her hands and knees. As I fucked her Ted stared at me. I finally came and rolled off her. We ended falling asleep pretty quick. When we got up the next morning Ted was still sleeping. Amy and I managed to bang off a quickie. About halfway through we looked over and Ted was starting to jerk off. We took pity on him and invited him over. Amy said, "I'll just watch" She lied and I fucked Ted. She lubed his ass and rolled the condom on me. As I fucked him she held my balls and squeezed them and he other hand was stoking Ted getting his medium erect cock off. I was a little freaked out wondering if the brother and sister might have sex. Not sure I care but not sure I care to see it. After I came I pulled out and I got a look from Amy like, one more for the road. Which we did, then breakfast and hit the road.

Driving back about 10 minutes in we all started laughing and agreed that was one fucked up weekend. I said, "Who won the game?"
