The first time I saw my first girlfriend naked, the one girl that I was insanely obsessed about, that's when I first masturbated. One afternoon we were hanging out and she started feeling a lot of pain, she had appendicitis. So me and her older sister got her on an ambulance to the nearest hospital.
The emergency room was packed and the doctors said they needed to perform surgery on her, but there was no room or time so they undressed her in front of me. Even though she was in considerable pain, she was still the most beautiful human being in the world for me, the most delicate flower of all. I watched, both excited and terrifyingly scared as they took off her top and bras, I looked briefly at the tender nipples I had fantasized about now for years, blood flowed down to my penis as a raging tide and it stood up in excitement in a way that I have no idea how it didn't rip them open.
I pushed my legs together in embarassment and tried to pretend I was looking away but the temptation was too intense, I could live with the embarassment of being thought a perv. And I knew that the best was yet to come when I saw her sister help her unbutton her jeans, my dick had obtained a life of its own, I was so horny I thought it was going to tear itself free.
In a few seconds they dropped her panties off and she was there completely naked in front of strangers, but feeling too much pain to worry about her modesty. Looking at her crotch, even if only for a few seconds, made me feel so intensely horny I don't know how I didnt drop my pants right there. My heart was racing and my hands were soaked in sweat. I stared like a shameless perv at the little hairs covering her slightly pale now not so private area, which was a sight too sexy for me to handle, I walked out of the room and went straight to a bathroom to get all that energy off.
It only took me a few seconds to cum, and I felt very guilty and dirty about the whole thing, but at the same time my hairs stood up in awe as I felt a degree of satisfaction and lust I had never imagined was possible. I never saw her with the same eyes again, and we broke up some months later and never actually had sex. She also had no idea I saw her naked that day. It really makes me super horny to think about that day and it is a delight to tell this story to a stranger, I hope you enjoy it.
