Watching the single man thrusting into my girlfriend's vagina, I felt a mix of heartache and pleasure. Fueled by alcohol, I struggled internally, but finally opened my mouth. Unexpectedly, the man cooperated, pushing his glans, wet with my girlfriend's fluids, deep into my mouth, plunging it into my throat. It was warm and moist. He pressed my head down, thrusting deeper and deeper, while my girlfriend stroked my hair, as if I were their plaything.
