Busted by aunt

My 40ish aunt (a bit of a whack job and quite obese, but nice) had just split with my uncle (my dad’s brother and a total asshole). She had no choice but to move into a rental trailer and a few family members, including me, got drafted into helping her move in. There was a lot of toing-and-froing going on and things were taking a bit longer than you’d think. There was little time to myself and less privacy, so I hadn’t drained my nuts in a few days and at 18 I was accustomed to jerking off at least 2 or 3 times per day. My aunt had kind of intimated to me over the years that she’d like to mess around as her husband totally ignored her physical needs, but nothing ever came of it and the idea wasn’t that attractive even to a compulsive jackoff artist like myself.

Finally, things slowed down a bit and my aunt headed out for groceries and booze, leaving me by myself in the trailer. This was my chance so I sat down on the toilet, locked the bathroom door, and took off my shorts and underwear. I languidly stroked my cock and soon built up to a throbbing erection. My mind drifted off to my aunt’s daughters, 2 and 3 years younger than me, who had often starred in jackoff fantasy roles for me when they were in their early teens. The eldest was a real goody two-shoes and my fantasies with her usually involved corrupting her, and the younger was rather tomboyish but with a rapidly ripening ass and titties that were truly drool-worthy.

I settled on the younger one in my mind’s eye to get me off. I had seen her changing into a bathing suit once through a cracked door, and even in her early teens she had a big bush and cute, hard nipples that I avidly recalled. My stroke picked up a bit, my cock started leaking lots of pre-cum, and my brimming balls tightened up in my ball-sack. Thinking I was still alone, I started moaning quite loudly which covered up the sounds of my aunt’s return. I was jacking like a maniac and just as I was about to hit the glory stroke and cum all over the place, the bathroom door burst open. My aunt had unlocked it by pressing in the lock mechanism with a screwdriver.

Auntie barged in, slapped my hand from my cock, and enveloped me in her mouth. Two bobs of her head later, I blew a huge load in her mouth which she swallowed in a couple of gulps. As I recovered from my ejaculation, she told me, “You don’t have to masturbate when your horny old aunt’s around.” I learned a lot about clitorises and oral sex over the next little while!
