While my girlfriend sleeps, this friend comes on to me as I rest my head in her lap. In that moment, I can't hold back and end up cumming inside her bare. Surprised by my own impulsive act, I wait anxiously for my girlfriend to wake up. The thrilling tension of this unforeseen situation and the underlying strain in my relationship create an intense, captivating experience.
