My two nieces

: My two nieces have been very sheltered all of their lives and now that they are turning 18 their curiosity about boys and that has become very evident. They are already becoming comfortable in their skin judging by the way that they dress around me, and I often find them staring at my crotch when we are sitting on the couch or going for a walk.
Every summer they come up and visit family and we all go for a camping trip together, and for some reason I knew that this was the year that I would be able to get with one of them. One is shy but sexy, the other is more social but I’d know would keep a secret. They are both around 5’3 and no more than 110 each. Both of them have round asses, fair skin, and very perky tits.
So one night we were all up late playing games in our cottage and one by one everyone was leaving to go to bed. Except me and niece 1 and neice 2. They both sat on opposite aides to me. It was clear they were flirting with me. Cute smiles, hands on my legs under the table, and the brushing of their tits along my arms and shoulders. I enjoyed watching them do this too me. Got me hard in no time. I suggested we go and watch some tv of none of us are tired. As we moved to the basement area I made no attempts to hide my errection, and it got their attention in no time. They Iglesias about it as we descended into the basement. We turned the tv on but all they wanted to do was talk. Again, sitting on both sides of me they wrapped us up in a blanket. They were extra flirty and they could not keep their hands off me. I was so hard but I had to show them my buldge. I pulled the blanket Down and they instantly Looked at my crotch. I called them out and asked them why they were staring at my penis. They just giggled. This was going to take all night so I offered to show them my cock . They said nothing so I just pulled it out. 7” cut. Shaved and clean. I had no idea what they were thinking but they could not keep theirs eyes off it. I took both their hands and placed them on my rod. I can come machine it felt weird but exciting. They looked at one another not believing that they were holding a cock in their small hands. Do you know what to do with a penis. The older one said suck? Go ahead, I prompted. Start by kissing it and licking it and when you’re ready slip it into tour mouth. As I assumed, the younger one was more into it than the older who had moments of genuine pleasure and giggle fits. They sucked me off for a while. I think it was the fact that I had two underaged girls on my cock that turned me on more than their skills. I eventually convinced them to show me their tits. I have always dated girls with big knockers so to see a set of perky tits was going to be a treat for me. They took their bras off and I started to massage their small tits gently. The younger ones boobs were twice as large as the older one. But they were incredibly soft too touch, and their nipples were so pointed and hard. I shifted in my seat and pulled them both close as a kissed and sucked on their tits. They both jerked me off as I did this. We were all very much turned on together. I could do anything with these girls right now, so I told them to kiss each other. They did. No giggles and no complaints. I was as hard as I had ever been and I needed to empty my dick but I knew these two were not on the pill and I had condom with me so I knew I would but with the then sucking my dick so I had them go back on my cock as I rubbed their wet and hairy pussies. They worked my cock harder as they were close to coming like me. I sped up my fingered then to cum. They shared my cock between them but it was the youngest who was going to get me there so I told the older one to lick my balls as the younger one continued to blow me. I explained to her that she was about to get my come. I unloaded so much cum in her mouth. She held the cum
In her mouth before I told her to swallow it, and she did. They soon came as well. We awkwardly said good night and went to bed. By the end of the week we had got together one more time with the three of us and I ended up ducking the youngest one after taking a detour on one of our bike rides. But that’s another story.
