So my brother and I have been staying at home with my parents because of our college doing online classes. My brother’s girlfriend couldn’t go home and didn’t have anywhere to stay. So my parents decided to allow her to stay at our house. So one day I had gone for a run while our parents were away. I guess my brother and his girlfriend had planned to have sex because when I walked into the living room she was sitting naked waiting for him. I just kind of stared and licked my lips. Eventually I said sorry and left. Later in the evening my brother went to pick up dinner. So I went up to her wanting to apologize. While I was talking to her I kept staring at her breasts. She’s like up here. I make eye contact with her. She asked if I liked what I saw. Without really thinking I kissed her. I stopped saying we shouldn’t do this. She kissed me back. We made out for a minute or so. I whispered in her ear I wanted to go down on her. I took off her shirt while taking off her shorts. Then I took off her bra and kissed her nipples. I then moved down and proceeded to according to her the best orgasm of her life. I wanted to end it right there because I was afraid of my brother coming home. But she wanted to go down on me. I had her come to my room next door. I stripped off my cloths and laid back on my bed and motioned for her crawl up to me. We kissed again and she kissed my nipples like I did to her and then she went down on me. She was pretty good for a first timer. Right as she was making me cum I couldn’t really help my moans and go a little loud. I heard a bang on my door. It was my brother back with the food. I told her to hide and then go back and get dressed and say she was in the bathroom while I had my brother make sure my meal was correct. He didn’t suspect a thing. She’s not so straight anymore as we’ve been hooking up sleeping with each other since then.
