I was seated next to my first love at a class reunion. I couldn't contain my arousal at the sight of her cleavage, which had grown since she became a married woman, and her defenseless panties when she was drunk. I accompanied my drunk girlfriend to the bathroom, but she was actually pretending to be drunk and waiting for me to have sex with her alone. I grabbed my erect dick and pressed it against her big ass, and she sucked it, and then we had sex in the bathroom. I couldn't get enough of her panting face in the mirror. A classmate found us, so we switched places and continued having sex!
