My GF and I switch roles. When we met she told me she fantasized about pegging a guy. I agreed and she pegged me a few times. She loved it but I always felt (secretly) that the prep work, clean up and don't mention the discomfort were a lot but I always try to be an open lover and I continued to agree. Well last night, for whatever reason I was feeling like I needed her to take control. I was teasing her when i got out of the shower by laying on the bed, stomach down and arching my back. She couldn't help herself (she has an ass fetish) and before long she was eating my ass while stroking my dick. After some time she told me she wanted to fuck me and i agreed. As usual she lubed up, I got on my knees and we spent time with her fucking me while I went through different levels of comfort. I'm not sure why but she asked me to stand up so she could fuck me and I did. While standing she was biting my back, fucking me and jerking me off. For once I felt no discomfort so i backed up to her and arched my back, she went crazy and started fucking me faster while stroking my dick with a hand full lube. After a few minutes she pushed me on the couch, on my knees and continued to hammer me. By now I can feel the orgasm build and I'm asking her to give all to me. The rhythm of her fucking me while pumping dick made me scream when I finally came. I could feel the front of her thighs slapping the back of my thighs and i felt nothing buy pleasure. After I came, i just fell forward on my stomach, I could not believe how hard I came. She let me lay there panting for a few minutes then she laid down next to me. We woke up on the couch in the middle of the night then went to bed covered in sex. It was incredible.
