I came home one night. As I was going to room I walked passed sisters room. Her door was slightly open and I was going to say goodnight. Before I opened her door all the way I saw she was on her bed watching something on her phone with her pants off. I stopped before going in and watched as she was fingering herself on her bed watching porn.
I left and went to my room without her noticing. I started to jerk off but got the idea in my head to somehow interrupt her. I was rock hard wearing boxers only and walked to her room. I pushed her door open walked in and was beside her bed.
She was startled and stopped what she was doing. I pretended to be startled as well but was now beside her with a rock hard erection.
She yelled what are you doing? I responded my bad came to say good night I didn’t mean to interrupt her. She told me to leave. I said I would and made fun of her for being home fingering herself before I left.
At her door about to walk out i turned back and asked said “too bad one of your hot friends aren’t here to help me take care of this” and pointed at my erection. She told me I was gross because I was her bro.
I told her I was very drunk and she should take it as a compliment I was so hard that if she wasn’t my sister we would be 69ing . I told her I was joking at went to my room.
10 minutes later i went back to her door. I knocked and she let me in. I apologized for earlier and she forgave me. I told her I was drunk and my date left me after a long make out session without going any further and that’s why I was extra horny and that she wasn’t at all hot or sexy to me.
She seemed offended so I told her she was hot but not to me because I’m her big bro. We chatted for about 10 minutes and while chatting I got hard again. This time in front of her. And my cock poked out of the opening in the front of my boxers.
She told me I was gross again. I looked at her and asked if she finished what she was doing before I interrupted her the 1st time. She told me no and started staring.
I started to stroke myself in front of her. She was shocked asking me what I was doing. I told her not to worry that I would leave in a minute. She told me to stay.
She asked to watch me. After a few minutes I told her I wanted to watch. We were across from each other on her bed. I was watching her finger herself she was watching me jerk off. I got close to her and gently pushed her onto her back. She asked what I was doing and I told her to relax. As she lay down I started to go down on her. At first she was in shock and surprised but after a few seconds she was into it. After she came I told her to suck off her big bro. I came in her mouth and left.
We did the same a few nights in a row after but never again after.
