When did it start? Hmmmm Well, I actually ate my own load the first time I'd ever cum inside a pussy; the pussy of a slightly older girl I met talking on a chat line.
Fortunately, my Mom and sister were out of town for the weekend, so there was no danger of any one interrupting. And I was finishing my third can of beer before my mystery girl arrived in a taxi about 11:00 PM. As I recall, we each had a beer, but there was nothing else to wait on, so we headed into my Mom's bedroom. Heck, she had a queen-sized bed; there was no sense in losing my virginity in a creaky, old twin bed.
We got started with some kissing and bodies rubbing together. I'd already read some erotic books like The Happy Hooker, so I knew it was good to get out of my clothes and help her take hers off. I was dying to squeeze her boobs knowing it was a prelude to finally having intercourse.
Before I knew it, I was climbing on top of her into the missionary position with a cock so hard it could have cut glass. Fortunately, I'd warmed her pussy using my hand as foreplay, my cock slipped into her waiting opening with an ease much like a straw pressing through the "X" cut into a plastic lid on a soda cup where the "X" had previously had a straw pushed through it.
I had a good buzz and was fucking for the first time in my life. I was happy; I was excited. Although I have no idea how much time had elapsed, I'm sure I couldn't have gotten her off when I exploded inside her. I kept pumping until there wasn't a spasm or drop of cum in my body.
Here's where my inexperience came into play. Caught up in the moment, not wanting our session to end, and feeling the need to check another sex act off the list of firsts, I slide down to meet my first pussy up-close and personal. Without hesitation I started licking her glistening, sloppy pussy. A pussy that I'd just filled with my own cum.
I wasn't turned off by the taste because I'd tasted my own cum a few times when I masturbated. My load didn't taste like much of anything to me, though the slick, sometimes blobby texture didn't excite me. Regardless, I continued to lick her for a while longer.
I can't tell you what caused us to stop, but we did and we took turns cleaning up in the bathroom. By now it was after midnight, and the beer and sex had taken its toll on me. I know it wasn't long before I fell asleep, which resulted in another male sexual first. I quickly fell asleep on a woman without her having an orgasm.
We awoke early; shortly after 6:00 AM. After she'd called a cab, we exchanged an awkward goodbye. Then she slipped out the back door and cut across the fenceless, neighboring yard to meet the taxi. We never connected again; I have no clue as to her name.
In parallel, I'd been collecting porn any which way I could. That sounds funny to say these days, but in the 70's there weren't many places to buy anything raunchier than Playboy. My friends had nicknamed my stash "The Library", though I rarely shared. I felt like a pervert when others knew about it. Turns out I was... not that there's anything wrong with that.
