Between Siblings

It is set up in many ways to begin but generally speaking, I believe siblings are set up in a situation where they have sexual urges they crave to fulfill in the moment.

I never had that much interaction with girls apart from my sister. It was my birthday and we decided to go out on a helicopter ride for fun. My sister is a modest person due to religion and I never saw her in any sexual way nor felt attracted.

After the helicopter ride, she claimed that she was going into a clothing store to take a look at some things. She took me along the bra and panties section while shopping for other clothes which made me uncomfortable. She begged me to buy it as she felt embarrassed to ask our parents. I said fine and told her that she should not mention me as buying it.

She had a heap of clothes she wanted to try on and the store had a change room. I thought she would go in alone but my sister told me to come and help her try the clothes on. I was wholly shocked and asked if she'd even be comfortable with that. She didn't mind so I budged and went to the change room.

It was not so bad initially. She would just try on a shirt to top it up. Then she started removing her shirt to just a bra. She even pulled down her pants to the panties and I was shocked. I had an instant arousal and tried to hide it, but my sister saw the bump. No doubt about that: I couldn't lie that her breasts and the curves alongside her panties were stunning. I apologized and begged her to please forgive me.

She didn't seem to mind and then she told me to turn around for a second. She unhooked her bra stripped down to no clothes at all and told me it was safe to look again. I was hard and did not know what to say in a state of shock. I just complimented her nude body and just said that she was gorgeous. I kept staring at her breasts and looked between her legs.

I did not say anything as she put on again the underwear and the bra then tried the remaining outfits. We went out of that changing room because I was shocked, and I bought her anything she wanted to buy.

As we stepped out of the mall, I thought of having the best sex of my life with her. When she smiled at me, she came to hug me and I hugged her back while gazing into her eyes; I just could not resist and kissed her on the cheek and she said she might as well accept a full-lip kiss if I liked her that much.

I deeply kissed her on her lips in public and she reciprocated by participating. After that, I took her hands and we entered into a coffee shop. And we kept kissing and all the public assumed that we were dating, which was unofficially the case.

Later I asked if she could be my girlfriend and told her that it felt weird since we were biological siblings so she could decline. She told me she wanted me to be her boyfriend and we ended up being a couple. We both agreed no one was going to find out about our relationship. On the way back home, I became a lot more touchy-feely as I pressed her breasts against me while hugging and slapping her butt for kicks. She retaliated by jokingly grabbing my penis. The minute we reached our locality we had to act as if nobody knew anything at all. Very much later in the night at around 11 PM, our parents were asleep and I just came out with my phone and sent her a message on Instagram, telling her I was bored. She asked me to come into her room so I slowly crept in and closed the door. I crawled under the cover and we laughed and kept kissing.

It seemed that we were heading onto something that we could not turn back. Our kissing got wild as she undid my shirt. I took her shirt and pants and unhooked her bra and she lifted her legs as I threw her panties to one part of the room and she threw away my boxers. Our two completely naked bodies were under the blanket, and we hugged each other very tightly and could feel each other's body heat radiate.

I spooned her naked for 5 minutes while kissing. I confessed to her how attracted I felt seeing her undress. I told her how much I loved her as a sister but wanted to love her differently now. We could have a deep and meaningful conversation and she turned around and hugged me very tight, showing that she felt very safe around me. All this while our private parts were touching and I resisted penetrating. The whole night, no sex. We weren't ready for it yet, but she hugged me the whole night and we kept telling each other how much we cared for each other. At about 2 AM, we quietly got up to dress each other again, and then I kissed her goodbye and left. That whole night, I had to finish in my head by jerking off to what had just happened the last few hours. I busted all over the room and couldn't help but still feel turned on at the idea of creating a mess inside her.

For about 2–3 weeks, we weren't having sex and our relationship was just going out on dates, kissing, and touching. One day while we were out, she had a serious conversation and said she felt ready to try intercourse. I asked her about what happens if she gets pregnant and she just said she would take a Plan B pill after.

I also informed her that we could not do it at our home as it was a room in our house, and everyone at home must have heard us and must have surely shouted at us for creating too much noise. I asked her whether she would take one day off from school and I would check into booking a hotel for that day so we could spend some private time together without anyone judging us.

I booked a single-room hotel for the daytime. We had lunch at a restaurant beforehand, then we entered our private hotel room.

That was so intimate when she sat on the hotel bed in very sexy lingerie. I undressed in the bathroom into a towel and went out of the bathroom with my very hard penis. I took the robe off and immediately sister had me into the bed and we were playing around and kissing. I tried to be easy as we wrestled. I then lifted her hips to take out the panties and we lay naked in bed after that. She gave me a blow job and was sucking down and I tried as hard as I could not to bust it. This was my girlfriend's first time and mine, and I had heard that girls do not like guys who bust it too quickly.

She was sucking me off nicely with her mouth while I kept yanking on my balls and she giggled, "What do you do?" I said I was just trying to stop it. She laughed.

We wrestled nude and we fell on the carpet. I played on her breasts sucking her nipples for fun. I then sucked her vagina and used my tongue to arouse it. Lastly, I had thrust the tip in but did not give up stopping myself from giving a load. As I kept entering and exiting while she kept moaning, I continued to yank my balls to stop the cum, and it worked effectively. When it was late enough and she felt good, I finally managed to have an orgasm inside her and I could see semen dripping. She was still laughing; I was laughing too. She got up and started hopping to provide thrust and I must have busted 3-4 times inside. I knew she was going to get my biological sister pregnant but we were having too much fun. I fingered her, she gave me oral sex, and we fucked in different positions.

As we were leaving, we took a shower naked together, got dressed, and left the hotel on our way back home.

We got a chance one time when our parents went out of the house for the day so we decided to tape this time so we could post online. We wore only black masks with holes in our eyes, and we recorded a sex tape of us copulating. No one knows online that we were the real brother and sister nor does any person in public. At this point, we have dated for about 1–2 months and are going to continue having a relationship.
