(Quick backround: I've been masturbating since I was younger, but I got serious a couple years ago. I'm 5'7' with blond hair, fairly wide hips, and 34B chest)
It was my first day of my sophomore year of high school, and my new boyfriend and I were hanging out at my house. We went up to my room, and we started talking. I had gotten sunburned on my shoulders and chest, and it was starting to hurt slightly. I asked him if he wanted to put aloe on me. Naturally, he agreed. I took my shirt off revealing my tank top and my bra straps. He started rubbing the cooling liquid on my shoulders, then on my chest. He missed a spot that was kind of on my boob so I said, 'A little lower. It's okay you can touch me there.' He smiled and put it on. I turned around and saw a nice bulge in his pants and I giggled. He asked if I wanted to see it. I agreed, and he took out his 5-inch boner. First cock I ever saw.
We then got totally naked, and he started playing with my B-cup boobs, my nipples rock hard. He wanted to screw me, but I wasn't ready for that yet. So I grabbed my vibrator from my closet and said 'We can masturbate with each other, though.' We sat on my bed with our legs spread apart. I turned on my vibrator and touched my lips with it, and he started rubbing his cock. We both shaved, and I had been bikini waxed recently. I Moved my vibrator from my clit to my vagina and back again, as I always do. He seemed to be jerking slower so I can orgasm first. When it started to hit, I shoved the vibrator deep into my vagina, and laid back on the bed, and gave my self a decently-hard orgasm. As soon as it died off, he knelt over me, and came all over my face and titties. We kissed, and the cum smeared all over our faces and chests. I don't know if it was the cum or not, but my burns healed really fast.
