Bike Ride with Sister

by Anon

Caution: This story contains strong elements of incest sex between brother and sister

Hi, my name is Jim. My story is about the summer my sister Anna and I shared. My story begins about three weeks into our summer break.

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 every-thing 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.

"Ware swim trunks because there was a creek where we were going that we could swim in." Anna said.

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.

"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 herself. 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 stiffened while I fantasized a little.

"Will you put lotion on my back?" she asked while handing the body lotion to me.


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! 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?"

"Hell yeah! You do! Man I can't believe my sister is wearing a thong bikini."

"Stop ogling my ass 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 countless times before, but this time I seemed to be getting horny from looking at Anna. Any guy would, but I shouldn't as 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 blowjob. 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."

"Did you cum?"

"Yeah. She did me until I came. It kinda went all over the place. Some on my stomach, some on my shorts and some on her hand. Luckily, we had napkins. She helped me clean up the mess. And she really drove me wild when she licked off the cum that was on her hand. That was a sight!"

"So, you liked that, huh? Why didn't she want to give you a blowjob?"

"I dunno."

My cock was hard from thinking about that night. Not realizing it, my swim-trunks were sticking up like a tent. Anna noticed.

"I see you have a hard-on from telling your story."

Anna rolled over to prop herself up onto her elbows.

She left her top on the blanket, exposing her breasts to me. Her breasts were nice and round. Two little triangles of untanned skin showed. Her breasts were glistening from the oil and sweat.

My sister reached over with one hand and placed it on my hard-on.

"Do you want me to do you, I mean show you what a blowjob can really be like?"

My mouth was agape as she rubbed my cock through my trunks. "You what... ?" I asked.

"Let me show you what a good hand-job and blowjob are all about."

I didn't know how to respond. Anna's hand slipped inside my shorts. Skin on skin. Her fingers lightly stroked the underside of my cock. Then she reached down further, stroking and squeezing my balls. Grabbing a hold of my hard-on, she stroked it for a bit before pulling her hand out.

"Let's pull your swim-trunks off." she said.

As I reached down to pull my pants off, Anna was reaching for the lotion. She poured lotion onto her hand and rubbed them together. She got up and knelt between my legs. With hands all greased up, she went back to work on my cock, one hand stroking and the other squeezing my balls. Her technique was wonderful. Of course, at that time I only had one other experience to compare it to. Watching my beautiful sister giving me a hand-job was too much.

I almost came, but she stopped. I looked down to see why she had stopped.

Anna was scooting back away from me. Then she bent over my cock and took me into her mouth. Her mouth was warm and wet. I should have blown my load right then and there. But Anna was deliberately slowing her sucking, stopping at the head to tongue it. I watched the top of her head bob up and down. Her thonged ass was sticking up in the air. What a sight I couldn't believe my luck!

Periodically, she pulled her head back so that I could see my cock in her mouth. She would look up to see my reaction. She would lick the length of my shaft from tip to the balls. Then she would stop and work on my balls, occasionally taking both balls into her mouth while her hand stroked my dick.

Anna could tell that I was about to cum. I couldn't control my heavy breathing. She quickened her stroking and fondling, as she flicked her tongue over the head of my now pulsing cock.

"I'm gonna cum," I said through my clenched teeth.

"I want you to watch me as you cum," Anna said.

I obeyed and looked down at her thonged ass up in the air, head tilted back for me to see. With my cock in her mouth I could see and feel her tongue frantically working to make me cum. Her hand stroking faster and faster to bring me to orgasm. At the last moment Anna took my cock out of her mouth and placed the end of it on her tongue as she stroked me.

In the seconds following, my cum started shooting out. The first jetted out onto her tongue. Because her stroking was so furious, the next string of hot cum struck her on the cheek and chin. This ran down her face. More and more of my cum shot out uncontrollably. I could see that I was filling her mouth. There was so much that some of it began to drip from her tongue onto her chin. I could see her trying to swallow as much cum as she could, but there was still some that leaked out onto her lips and hand. As I came down, she licked up the cum off of her hand and me.

"Oh Anna, that was wonderful!" as I panted to catch my breath.

"We're not done. Next you're gonna return the favor!"
