I live with a couple of friends and every once in a while my gf comes over and stays for a bit. My roommate's gf and I have been getting closer to each other recently. So on the special day, her boyfriend left for work and me and my gf assumed she was sitting in her room so we got started. I was the hardest I can ever be and ended up fucking the brains out of my gf. My gf and I got pretty noisy but we knew the noise doesn't travel all the way to their room.

After a session of rough passionate sex, we got dressed and got cleaned in the bathroom and my gf got ready for work and left. Now that it was just me and my roommate's gf, we hung out together watching some shows, and we have this thing where we remind each other to eat since we tend to forget. I proceed to ask her if she ate saying "Hey did you eat? I didn't see you eat anything!" and she said "oh I did but you were busy" and winked at me and looked me up and down.

I felt embarrassed but also very turned on because she kept on teasing me saying things like "Oh I bet you burned alot of calories pounding her with your big cock;)" and similar teases. I asked her how she knew I was big, ‘it’s pretty obvious from the sounds she makes and the comments’. She stares off saying ‘I’ve always wanted to be with a big guy’
