I fucked my brother while his gf made dinner

A few days ago I decided to go come over to my brother’s house. We started talking and I felt really close to him. But then it went a little too far...  He asked me about my sex life, which at first I found a bit strange, but anyway I told him that it is not very eventful lately because I hadn’t had sex with anyone since me and my boyfriend broke up.

His girlfriend entered the kitchen and interrupted our conversation by asking what we wanted to have for dinner and I said I didn’t mind. She began dinner preparation, me and my brother went upstairs to his room and continued over conversation. I honestly don’t know what happened next but basically the conversation about sex that made me feel like I wanted to be closer to him. Nervously, I asked him why he asked me about my sex life and he told me how he felt. He said he’s always wanted to fuck me and I couldn’t help but feel turned on.

He started undressing and revealing his six-pack, I started getting wet down there and I couldn’t control my thoughts anymore. I started undressing as well and couldn’t kept getting so turned on by the way he looked at me. He gently touched my lip and without thinking, I took his thumb inside my mouth and started sucking it. His dick became rick-hard in a matter of seconds. He got closer to me and I could feel the head of the skin touching my pussy lips. Without thinking too much I turned around and he put his dick inside and within a few minutes he came so intense so deep inside.

Feeling both embarrassed and excited, we got dressed for dinner, and went downstairs to help his girlfriend with the preparation. My brother came to the kitchen a few minutes later and sat down at his usual spot at the dinner table without looking even a tiny bit ashamed. His girlfriend didn’t notice anything. I know it was wrong, but all I could think about was my brother’s dick inside me the entire time. I left my naked photos on my profile
