When I was young, I was frequently left with my aunt for around 4 days a week so my parents could work. She had long thick dark brown hair. A decent pair of boobs, the kind that jiggled, but slightly sagged due to her being 41. She had a large ass due to diet, big hips, and skinny everywhere else. When I turned seventeen, my hormones were raging. I was sexually attracted to every girl I saw. Back then I was confused because I grew up in an extremely conservative family and didn't know much about sex, and especially not what a female's body looked like under her cloths. The one girl I became interested in more than any other, was my aunt. See, we had nicknames for all the family members at the time, because the younger kids had trouble pronouncing the names. My aunt's name was Dinah, so we called her Di Di. That summer, I left for Michigan to live with my grandparents for a year.
I returned the next year, and everything had changed. One of our dogs even died. My aunt had had surgery and the medicine she was on messed with her hormones. Her boobs grew a size, which eliminated the sag, and she was more hyper and happy it seemed. Over the next few days, I also noticed her covering her crotch frequently. I put two and two together and realized that she was horny as hell.
The next week, she invited me to spend the night with her in a purely family way. We used to do this all the time since she was like a second mother to me. I entered her house at 7:00 p.m. I tiptoed back to her room to scare her, but I heard a noise. I stopped at her doors, which are folding doors allowing me to see slightly in and hear the sound. She was moaning, and rocking her legs back and forth. I didn't know what was going on. All I saw were her legs moving but she sounded in pain. I thought to help her, but she didn't have any pants on so I decided to leave. Right when I got ready to leave, the moaning stopped. I entered the room forgetting that she wasn't wearing any pants and said hello.
"Oh, hey bud!" I asked if she was ok and told her that when I was coming back to the room, I heard moaning. She looked surprised and said, "Yeah, my stomach was hurting but it is better now. I looked down and remembered that she was only wearing panties and a t-shirt.
"Oh, sorry. I didn't know you didn't have pants on!"
