Brief recap. My step sister Rene had asked her best friend Martha for a sleepover. Mom and Dad were going to be out very late. During the truth or dare game I was dared to show my "rig "as they called my cock. I was measured by the girls and they both agreed that my cock was about an inch longer than their exboyfriends were. They stroked my cock and balls as well. I didn't know exactly where it was going, but I decided to roll the dice. My turn I announced. They looked up at me and I said I dare you both to get naked to. I was really scared I might have stepped out of line. Martha ever in control said I wasn't naked. True my pajama top was still on. My bottoms were at my ankles. I had them off and in a pile in about 3 heartbeats. They were smiling good sign I thought. Martha said sit in the middle of the couch. I did as I was told. Martha whispered in Rene's ear and Rene stood up. Rene turned an gave me a wink. Martha crawled over to her side and asked if I wanted to see Rene's cute little ass. I  nodded try to be cool. What?  Martha asked I wanted to see.  Rene's ass I said not sounding cool at all. She ran her hands up Rene's legs slowly but surely. I didn't know why they didn't just toss aside their nighties and be done with it. Next thing I know Martha was squeezing Rene's ass. What the hell is going on. She slowly slipped Rene's panties down to her ankles and threw them at me. I thought she might say I had to put them on me. She didn't. She ran her hands up to Rene's ass again and stood up herself. Martha ran her hands up Rene's back and over her shoulders. I couldn't tell if she was feeling up Rene's tits or what exactly but Martha smiled at me and  she slipped the straps off Rene's shoulders one at a time . She let the the top fall to the floor. It had a lace up tie to it. Martha asked me if I wa ready to see Rene's bady now. Fuck yes I was. I nervously said yes. Rene slowly turned around and damn she was so fucking hot to me. Some where in the Gina Gerson /Sarah  Mila body type. She didn't resemble either one but beautiful none the less. Rene basically returned to favor with removing Martha's nightie in a similar fashion. Including the grabbing of Martha's ass. She was more like Britta in my galleries a very little resemblance to her. Much much darker skin she was  a Latina after all. OK we were all naked and I was still hard as hell. Not wanting to mess things up I figured it was going to be their show. I  didn't have to wait long. Martha and Rene turned to each other and fondling their tits they kissed! OK cool but I was shocked and my cock was getting harder. I wanted in on the fun too! Rene told me later they had practiced kissing with each other so they wouldn't be embarrassed about kissing boy's. Sounded reasonable at the time to me. I  still wanted in though. Martha finally told Rene to show her what she could handle. I didn't know exactly what that meant but they were walking towards me. Rene sat down on my left Martha was on my right side. Rene leaned over and kissed my cock on the head and took it in her mouth. I watched as she took as much as she could. Martha I remembered was naked and right beside me I reached over and started to play with her toy. She said be nice if you want your rig in my mouth. I did so I was nice. She told me I should know how to lick and suck titties so she would have to show me. She leaned over and licked and sucked my nipples. I love that anytime anyone wants to do that to me. She was really great at it. About that time I let my hand slip down her back to get my first feel of a naked ass.  Martha finally told Rene it was her turn to have a taste of my rig. Rene kissed the head again and asked how I liked it. Amazing I said. Martha didn't bother with a kiss she went down on my cock and made herself gag  a little. Rene and I started kissing and touching each other. I finally got to lick and suck on her tits. I was really happy with everything. Martha pulled up off my cock and announced that it was time to see if I was ready to take a taste of them. I was really ready for anything. I didn't know how to eat pussy and I could use the info. Martha spred Rene's legs and told me what to do. She pointed out Rene's clit. That's your main focus. She said I wasn't allowed to use more than 2 finger's in her box. She said  watch me and she started to go down on Rene. Rene smiled and said she liked what the feeling slot. I kissed her and started licking and sucking her tits. Martha finally told me that it was my turn to lick Rene's box. I wasn't perfect of course but I didn't want to disappoint Rene. It was a couple minutes into the my first time and Rene started to move a little. I thought I had to keep my tongue flicking her clit or it would all go wrong. I lightly clamped down on her clit covering it with my mouth. Flicking my tongue and lightly sucking a I did. She said oh fuck I thought I was doing something wrong I stopped and pulled off to ask If I was doing it right. She grabbed my hair and and said don't stop. I went back to her pussy and kept going. Martha finally broke us up. I wanna see if he's any good she said. Rene's pussy had a little gap of shaved pubes the full length of her bush on both sides. I  found out that she had shaved it so her pubes didn't stick out of her bikini bottoms. Martha had no clearing off the sides she was a little furrier than Rene and I combined. I  didn't care I was looking forward to tasting Martha's pussy to. Martha spred her legs and I took my spot. Martha did have a differ taste ,but I liked it. She told me to do that trick  on her so I did. She said it was good and to keep going. I just wanted to have my mouth on either one of their pussies. Martha would later say that I made her cum real good. I don't know really. The whole time I hadn't thought I was doing everything right. I must have been OK at worst because Martha told Rene we should get him to pop. She gave me her wicked little grin and see if he can swing his rig. It was amazing to see them work my cock as a tag team. I could have sworn that they had shared a cock before. I  wanted to pop in Rene's mouth. Martha was the lucky one. She said oh man you gotta try it. Rene had already but Martha didn't know. I didn't know what snowballing was until I saw them. They called it swapping. I would have thought it was over now. 20 minutes later Rene asked if I was ready to pop again. I told her I didn't know  if I could pop again. But I was willing to try.  I tried my first 69 with Martha. She told Rene I was ready Rene slide on to my cock and took it all. They traded off riding my cock. I just loved every second.They told me to make sure I didn't pop in their pussies. Rene was ready to catch my second load. She shared with Martha . We never had another 3 some. But I did get to fuck them both a few times induvidually. Never got to fuck my girlfriend at the time. Not untiI met her in a bar years later. Even bigger changes were about 6 months away.
