I'm preparing to go to bed and my boyfriend joins me. I sometimes pee during the night on the sheets so we decided that I'll be using diapers (my bf loves watching me in them). I wanted to go to the bathroom but he asked me to pee in diapers while laying on the bed. Gradually, my bf becomes more and more excited and takes off the diapers while my pussy is still wet with my pee. He fucks me missionary covering my pussy with a diaper and cums on my pussy lips. I enjoy this feeling so much that put on the diapers again so his cum gets absorbed into the inner side of the diaper)
