Watching the single man in front of me constantly thrusting in and out of my girlfriend's vagina, my heart was filled with sadness and pleasure. Under the stimulation of alcohol, I kept struggling inside and finally opened my mouth. Unexpectedly, the single man also cooperated with me and put the glans with my girlfriend's body fluid into my mouth and kept pushing deep into my throat. It was warm and wet. He pressed my head and thrust deeper and deeper. My girlfriend was also stroking my hair as if I was their plaything.
