My aunt B
In the summer before my junior year in high school mom, dad, and I moved in wtth my grandmother and mom's oldest sister. It turned out to be an exciting sexual experience for me! I had a bedroom on the attic floor all by myself and isolated from everybody else. I was at that age masturbating five or six times day and evening, and loved the privacy that isolated room gave me.
On Saturday morning after a date the night before, I drowsily woke up with my usual morning woody on and began a deliberately slow rub down of my boner. I had my bed sheet thrown back so I could admire my seven inches which had been lovingly caressed by my girl friend. She wouldn't 'go all the way' but really enjoyed watching me get off. After which she wanted her reward of my fingering her to a very wet and thrusting orgasm of her own.
While I was dreamily remembering that I heard a sort of stifled gasp and turned my head and saw aunt B staring at my red knobbed erection with her hand over her mouth. All I could do was to bugeyed look up at her and try to cover my hard cock. She just stood there with her eyes glued to my teen age hard on. She then closed the door and began to apologize for intruding, but, she said, the door was open and thought that I was up. She then assured me that she wouldn't tell my mother what she had seen.
Then she told me that she knew that young men needed to relieve themselves that way. And she reminded me of her son who was about 15 years older than I and that she seen him 'rubbing' himself like that too. Her face was flushed, and suddenly I began to instinctively realize that she was erotically stimulated. (point of honesty). I certainly couldn't! have expressed it that way.
Then, in spite of my fear, I began to get hard again and she kept taking looks at the sheet covering my rapidly growing hardness. Making me even harder. Finally, she put her hand down on the tented sheet and smiled a little. She said that she hadn't seen a young man!s cock, her words, since she had seen my cousin playing with himself. And would I let her pull the sheet back. I was too dumbfounded and gasping with horniness to even answer. I must have nodded because she slowly drew the sheet back and stared at my raging and by then literally quivering hardon.
Then, she just slipped her hand over my cock and began to masturbate me. Emboldened by that. I slipped down the straps of her thin summer nightie and saw the largest breasts I had ever seen.
Later that summer, aunt B asked me if hers were bigger than my mom's. I assured her that they were,though I had never felt mom's.
