My twin sister and I have been total opposites since birth. I was always into sports and she was always into school. I struggled and she excelled on school. I had all the friends and she kept to herself.
College was the same. I stopped partying and concentrated on school and Jane breezed her way through. We both went to our hometown college so we stayed living at home. I never known Jane to ever have a boyfriend in our 21 years, let alone have sex. When I saw her leaving the glory hole area, I was in complete shock.
I put my dick back in my pants and left the room. I went out into the main area and found my one friend that left early. A few minutes later, the other friend came out with a big smile on his face. He told us on how good it was and was ready to go back. My friends looked at me and could tell something was wrong. I told them I got lucky but it was too odd for me. I didn't say anything about the experience or who had done it, I was ready to leave.
My friends went their own way after we got back to my apartment. I layed in my bed, trying to process my next move. I went through every senerio and didn't sleep any that night. What surprised me was how horny it made me feel when I thought about it and I was hard most of the night. I didn't want to but I knew I had to say something to Jane.
The next day, I asked Jane if I could bring some pizza over for lunch. Pizza is her weakness and she said yes. I got two of her favorite pizzas and headed over.
It had been a couple of months since I'd last seen my twin sister. She had changed her look. She has lost her conservative look and is now dressed like a single, 21yr old woman should. Nothing too bad but totally different for her. Tight leggings and a tight top that showed off her smaller breasts. I rarely saw her dressed like this and I noticed that she was very attractive.
We ate the pizza and caught up on what was going on with our lives. She told me she goes out with friends from college and parties some but not too heavily. She then told me she's exploring her sexual side since she lost her virginity. That surprised me but was happy to hear her loosen up. I was going to tell her about the glory hole but I chickened out. I just couldn't do it so I was just going to let it go.
It was getting dark and she told me she had plans to go out with some friends. She changed into a more slutty outfit that caught me off-guard. The thought came into my mind that she may go back to the adult store. She followed me out her door and we went our separate was or so she thought. I decided to follow her and see where she went.
Just as I had thought, she went to the adult store. I was far enough behind her for her not to notice. The place wasn't busy for a Saturday evening so I parked far away from her. Once she went in, I wanted a couple of minutes before I went in.
I looked around the front of the store and didn't see her. I knew she had went into the back. I paid my money and went into the back room. There was only one room that was occupied by a couple having sex. A quick glance made me hard but it wasn't my sister.
I went to the glory hole area and one door was shut. It was the same one she was in before. A nervous excitement came over me as I went into the door next to what I hoped was her.
When I shut the door behind me, I looked at the hole and there was a finger sticking thru it. I recognized her fingernail polish so I knew it was her. I had a nervous, excited feeling about doing this. I knew it was wrong but my dick told me to do it.
I pulled my pants down and stuck my hard dick thru the hole. I heard her say, "oh, it's you again. I was hoping I could suck your nice cock again." I then felt her warm mouth around my cock. My head went back and I moaned loud. She took me out of her mouth for a second to giggle at my moan before going back to sucking the life out of me.
This time, she wasn't doing it as good as before. I hate to say that but she kept taking me out of her mouth and moving around. Did she know it was me? I started to feel guilty about it and was about to pull my dick out of the hole until I heard her say, "Pull back." I did and the next thing I saw really shocked me. I saw two fingers come thru the hole, holding a condom.
"Fuck me," my twin sister said.
