Enjoying my sis's friends...

One of my first sexual experiences with another girl happened when I was about 15. My s****r and her friend were hanging out in our camper trailer when I got home from being out with my friends one chilly October evening. I was going to get in trouble when I got in the house, so I was reluctant to go in right away. I went in the trailer and was talking to my s****r Annie and her friend Sandra. Sandra has light brown hair, beautiful young boobs that I could almost get my mouth around, and a nice, slightly plump handful of ass on her.They both were younger than me by a couple of years, and Sandra had a bit of a crush on me from what I overheard earlier in the week. They were talking on the phone and apparently my syster had seen me jerking off sometime before and was trying to describe what I was doing, and what my dick looked like.
So we were just hanging out and talking when my mom called out to Ann that she had a phone call. Right after she went inside, Sandra moves in closer to me and she kissed me on the lips. I was kind of taken by surprise at first by her being that quick about it, but just started kissing her back.We kissed a little more then we heard the door open and my s****r walked out of the house. We immediately stopped and Sandra said don't let Annie know what we were doing. Annie walked in the trailer and said "your mom is on the way over now to pick you up". So we talked some more for a while, then my mom yelled out that Annie had another phone call. She leaves again and Sandra and I were alone again, so we started kissing some more, really getting into it, when my s****r walked out of the house with the phone and sat on the steps.

Sandra said "She's gonna be on the phone for a while now," and we sat down on the little couch so my s****r wouldn't see us and we were making out some more. By now my dick was almost totally hard now and I was hoping it was dark enough that she would not notice it. We had been inching slowly down and Sandra was just about on top of me when she noticed the front of my jeans bulging out. She said "Oh wow," and almost immediately I said "I'm sorry I didn't mean for this to happen" while I tried to rearrange myself to make it less noticeable. She then said "It"s was alright, I understand what happens to guys when they are making out."

We kissed again and now I'm totally rigid and I mover her hand down to my crotch and have her start rubbing me through my jeans. Then I pushed her hand down my pants while kissing her (it did not require hardly any effort she seemed like she enjoyed it) and then I unbuttoned my pants and she pulled out my dick and was stroking me really nice and I was getting close to cumming, when her mom pulled up to the driveway. She suddenly stopped said to stay laying down and got up and walked out of the camper and talked to my s****r while she got in the car.

My poor dick was so hard it started to ache as they backed out and drove off. My s****r then walked in the camper and saw me laying low on the couch with my bulging jeans freshly buttoned up and said "What were you guys doing in here while I was talking on the phone?" She had a sly smile as she said this and said that she had snuck up and peeked in the window and saw Sandra"s hand rubbing my crotch through my jeans. In the meantime my cock would NOT go down and it was throbbing now. Then she said "I guess you're gonna go jerk off in your room now, huh? I see you doing it sometimes when you thought nobody was home." I said "Please don't tell anyone, I wouldn't tell anyone if it was you that got caught doing it" I can't go in the house like this and maybe I'll just do it right here instead."

I started rubbing my dick through my jeans hoping she would get grossed out and leave me alone. She didn't try to leave and stood there watching. I said "You gonna leave? I need to do this, my dick hurts and you already saw me do it anyway."
"No." she said "Can I see you do it again? I won't tell anyone if you won't, and I didn't see you very good that night." I didn't say anything and just kept rubbing, then I opened my pants and took my dick out, stroking it the whole time. She said "Damn it looks bigger than when I saw it before. Is it really as hard as a bone? 'Cause that's why it's called a boner?" I said "The middle part is hard, but the top is still kinda soft." I was pretty hot and horny by now, and wanted to cum, but also strangely enough, wanted to show her about my cock. "Touch the head of it and then the shaft and see for your self." She was hesitant, but reached her hand out and then gently squeezed my cock head with two of her fingers and said "Oh yeah, is is kinda soft" then she did the same with the shaft and said "Wow, it is really very hard!" I then took her hand that was holding my dick and had her put her whole hand around it and squeeze it a bit. Then I started using her hand to jack me off slowly. She didn't try to pull her hand away or anything and just did what I wanted."See how it is? Now you keep doing this for a while until I'm ready to cum. This feels amazing, don't stop please!"

I was tempted to cum on her out of spite for not leaving me alone, but changed my mind and moved toward the wall and told her to stand off to the side a little. She said " It feels like it's pulsing and it looks like it got a little bigger." I said "Oh yeah, I'm gonna cum, don't stop!" I was breathing harder and faster, and she was looking at me with a slight smile, than I moved my hand away and let her take over by herself. She continued pulling and squeezing my shaft,and rubbing over my cock head until I started moaning softly then stopped and I saw her watching my dick as she was rubbing it. I was starting to feel my cum come up and we were both watching my cock when I stopped breathing and squirted out my first stream of sperm. It hit the wall with an audible "plip" sound, and I grunted and moaned as the rest of my load shot out all over the wall and my s****rs hand. Her eyes were wide and glued to my dick as I shot several more streams of cum out, and was almost legless from the relief I was feeling as I came and had to hold on to her to stay standing up. I was holding her ass by the time I had finished, and said "Wow! That was incredible!" She didn't say anything at first, then said "Eww, it's all gooey and all over my hand" Then I helped her clean it off her hand with some paper towels and wiped of my still hard dick as well. She said "It's still hard? Will it get smaller again? Please don't tell ANYONE about this, I can't believe I just jerked you off! What the fuck!" I said "It's alright, I'm not gonna say anything. Having my s****r jack me off might be considered weird to people, so I won't tell." "Thanks for helping me out, it was awesome, you did really good." I said, trying to ease her mind down some. "You better get inside, mom's probably wondering where you are now that Sandra left. I'll finish cleaning up here.

I went inside after, and got yelled at for not doing what I was supposed to do before I went out that day, but it didn't bother me at all after what I had just done earlier.


More about Sandra comes another day soon!
