When I was 18, one summer my parents had me stay with my grandmother for a month. She lived in a small house that she had been in all of her adult life. My Grandather had passed away young and lived alone ever since. My parents decided it was my job that summer to repaint Grandma's house, which needed a lot of work. Paint and repair. That was my job.
It was a particularly hot and humid July when I temporarily moved in with my grandma. Our home was three hours away so my parents thought it would be best for me to stay there until I finished the house repairs for her. The house was small with just 2 bedrooms, one of which was used for storage. There was one bathroom off of the main bedroom. I was eighteen that year, and my grandma Ida was around 60 if I remember.
I started this stay with sleeping on the couch, since grandma Ida had the master bedroom and the spare bedroom was floor-to-ceiling with boxes, sewing equipment, and assorted things.
There was just a since small window air conditioner in the house, and it was in Grandma Ida's room. It was miserably hot trying to sleep in the stuffy living room, especially after days in the sun painting the house.
After about four days, I was complaining about the heat in the house. Opening the windows was no relief, as a heat wave was solidly in place. One night at dinner Grandma Ida said I could move in with her in the bedroom where there was the one and only air conditioner.
To save money, Grandma only turned on the air conditioner right at bedtime. That night I washed my face, brushed my teeth and came into the bedroom just as she was turning on the air conditioner.
I felt a bit awkward being in her bedroom, but at the same time I hadn't slept well in days and was miserable from the heat. I got into the bed with my clothes on, but Grandma Ida quickly told me to strip down to my underwear to sleep in. She went into the bathroom to brush her teeth. While she did that I did as she said and stripped down to my boxers.
I felt strange being in just my boxers. I thought about going back to the living room to sleep. But the cold air blowing from the air conditioner changed my mind. I was tired of the heat.
From the other room she told me to lay on top of the sheets until the room cooled down. From the bathroom with the door ajar, she was talking to me about the paint job I was doing on the trim. And she asked about progress as she crossed the room and went into her closet, closing the door. She came out wearing a worn out nightgown, shutting off the light to the closet and walking over to sit on the opposite side of the bed. I notice that her enormous breasts were hanging quite low, all the way over her stomach. I knew she had large breast, I just had never seen them hanging unsupported. She did have on her thin nightgown but it did little to hide her body from my view. I pulled a sheet over my lower body since I felt my cock swelling.
She turned off the overhead light, leaving a reading light on next to her side of the bed. She then laid down next to me, propping herself up with pillows and grabbing a book to read, along with her reading glasses. I felt embarrassed and turned on my side away from her. I pulled the sheet off of me as I was still too hot to be under even the thinnest of sheets.
We spoke for a short time and I was quickly to sleep. This routine repeated itself for a couple of days, and I began to feel more relaxed in bed with my grandma, and actually started talking more.
It was a bit strange to be lying on top of the covers in just my briefs with my grandma next to me in a nightgown, but given the heat that summer we didn't have much choice. The a.c. in the window of the room was old and not working properly, so the little cooling it provided was just enough to make it so that we didn't sweat all night.
For the first week, I was tempted to masturbate in the shower. But it felt weird, perverted or something, to jerk off in the shower we shared. I did not want to get caught or leave tell-tale signs of my masturbation. Like a lot of teen boys in those days, I had grown up to believe that touching yourself was perverted, or gross, or a sin, or all of those. I had fallen off my masturbation schedule, which at the time was twice a day, and was starting to get hornier and hornier.
About a week after starting to sleep with Grandma Ida it happened: I had had a long hot day. I had been moving blocks in the backyard and was particularly tired that night. Grandma Ida and I chatted for a bit and I fell asleep right away, with her next to me reading a book.
