I did this once while I was staying at my dad's house. He went out to the bar and I was in his bed. I was horny and stroking my cock. He was snoring and I grabbed his cock. It was getting hard and I took it out. I started sucking him and he was groaning. He then said don't stop and he started throbbing and he came in my mouth
This jogged a memory from my 20s in DC. My friend had a friend named Rand who was older, bot unattractive but socially awkward. At least around me, as he made it no secret that he was infatuated with me. One night we all slept at his house, for some reason. I remember being drunk, horny and thinking about Rand coming in and fucking me. He did without his toupee and he made me cum like a fountain after sucking me and eating my ass
