I had just broken up with my girlfriend Jill. We had been dating all year and I thought it would last forever. She said she needed to spend time with others and wanted to date other people that summer. None of her reasons were very good. Well, we separated. I was devastated. I didn’t understand what had gone wrong. For about a week, I ran through everything in my mind to try and figure out “why?” It was driving me mad.

My sister tried to help. We talked about girls and relationships. She tried to help me make some sense of the breakup. Eventually, we both decided that it was best to let go and move on. Maybe later in life these things would make sense.

To help me take my mind off of things, my sister offered to take me mountain biking up in the hills near our house. She told me to wear swim trunks because there was a creek where we were going that we could swim in. I went and got changed and came back down to the kitchen to packed our gear and a lunch. After getting everything together, we headed out that morning.

We rode along side streets to get to one of the bike trails. My sister had been on this trail before and led the way into the woods. Anna’s very athletic and riding this trail was not much of a challenge for her. For me, it was a little bit of a workout, any bike riding I did was on paved streets.

Feeling sorry for me, she decided to go off the trail where the terrain was more level. She said, “We can take this route. It’ll take us a little longer.”

“Thanks.” I said.

After about twenty minutes, we arrived at our picnic spot. We parked our bikes under a tree and started to unpack our gear. Anna had brought along a large blanket to spread out on the grass. She laid the blanket out in the open sun. “I want to work on my tan,” she said.

Sounded good to me. What did I care?

As I brought our lunch over to the blanket, Anna set out the radio and suntan lotion. As we both knelt down on the blanket and before starting in on our lunch, we both began to take off our T-shirts and shorts. My sister’s body was really toned. She looked really good.

I unpacked the lunch as she worked on putting suntan lotion on her. I watched her oil her body as I ate my sandwich. Her body was glistening in the sun. The crotch of my trunks was getting kind of tight as my cock started to stiffen while I fantasized a little.

“Will you put lotion on my back?” she asked while handing me the lotion bottle.


She turned her back to me and pulled her ponytail to the side. What I hadn’t noticed earlier was that she was wearing a thong bikini!! Wow what a sight. I thought that I could only see something like that kind of stuff in Sports Illustrated.

“You’re wearing a thong bikini!” I said. “I’ve never seen you wear those before.”

“Relax. I just bought it last week. I want to have as little tan lines as possible. What-do-ya think? Do I look okay in it?”

“Heck yeah!! You do!! Man I can’t believe my sister is wearing a thong bikini.”

“Stop ogling and put the lotion on my back.”

I took the bottle in hand and squirted lotion onto her back. I spread it all over her. It’s funny. I’ve done it a billion times before, but this time I seemed to be getting horny from looking at Anna. Any guy would, but I shouldn’t because she’s my sister. Her skin was really soft and warm.

“You done?”

“Yeah, sorry”

She lay on her stomach and untied her top letting the strings fall to the sides. I could see the side of her breast, firm and round. I kept staring at her while I picked up my sandwich and returned to eating.

“Stop staring at me,” she said.

I finished my sandwich, put lotion on myself and laid down next to her.

“Did you ever have sex with her?” she asked out of the blue.

“What do you mean?” I asked stupidly.

“Sex? Did you and Jill ever do it?

“Well, not really.”

“What do you mean not really?”

“Well, I’ve never had intercourse with her. But she did give me a hand-job once in the theater.”

“Tell me about it”

“Well, we went out one Friday night to the movies. I don’t remember which movie.”

“I don’t really care about the movie.”

“I had been asking her to give me a blow-job. She didn’t want to do it, but finally agreed to give me a hand-job in the theater. We sat in the back of the theater and off to one side. As the movie got started she pulled my shorts down a bit and pulled out my dick. She started stroking me. It took me a while to get hard because I was so nervous about getting caught. But she kept working at it until that thought left my mind. I began to slouch in my chair as I got more and more excited. She was pretty good at it.”
