I'm 40 now but when I was 18, I was an extremely shy guy. My shyness had stopped me from ever advancing my love of women and a want for a relationship.
I was still very much a virgin living a sex life in my head and masturbating often. Sometimes three, four times a day.
My aunt, my father's sister, stayed with us for a couple of weeks. She stayed in our guest room which shared a bathroom with my bedroom, sliding door access from either room. The doors had locks but they didn't function well so the rule was, if a door is closed don't enter.
One afternoon while I was taking care of business jerking off in the bathroom, my aunt slid open the door just as I was coming. I was startled of course but that doesn't stop your ejaculation from shooting out. She was momentarily shocked but also almost mesmerized by my cum shooting out onto the vanity.
"Oh my God" she cried out. I covered up red with embarrassment and tried to leave. She stopped me, apologized for not knocking and told me how beautiful my erection was and how exciting it was for her to witness such a beautiful young man coming.
She took a washcloth soaked it in warm water, moved my hands from my loin area and wiped away my cum from my cock as she cupped my dick and balls in her hands. I was becoming not just hard but harder than I ever had been!
This was the very first time a woman had not just seen me nude but touched my penis.
She stroked me a little then stopped and turned to wipe the cum off the vanity.
She told me again that it aroused her to witness what she had and said my cock will make some girls very happy adding, "You are quite well endowed. Lucky them."
Two nights later, I was still getting over what happened and my fantasies were taking me to the act and want to fuck my aunt. Crazy thoughts. I need to jack off again with my fantasy driving me out of bed and into the bathroom to fetch toilet paper to take back to my bed and catch my cum.
When I opened my slide door to the bathroom, I took note of her adjacent sliding door being open about an inch and the light from the tv in her room flickering. I didn't turn on my bedroom lights nor the bathroom and quietly put my eye to the opening in the door.
I couldn't believe what I saw but there she was, my aunt laying nude on the bed slowly rubbing her pussy with her hands. I became instantly erect watching my aunt pleasuring herself.
My fantasies are always about eating pussy and here I was watching her fingering herself, her pussy wonderfully exposed. I wanted to bury my face into her love puddle.
I dropped my boxer shorts and began masturbating to the beautiful sight before me.
Her legs started squeezing together and releasing, then suddenly after many minutes of this, and without warning, they went straight out stiff as a board.
I realized she was having an orgasm. Wow was that ever beautiful. She laid there looking my way. I realized at that moment, she was aware that I was watching her. She knew I was there all along!
