A long time ago, when my ex and I used to fuck. Yeah, this was way before my dick got small. I was around 6 inches and thought I could fuck alright. Confidence is very important, I came to find. She was on birth control, so I usually came inside her.
So when we fucked she loved to talk dirty, and so did I. In the heat of the moment we said all sorts of things. Almost role playing sometimes. She was a slim brunette with short hair and small tits. Very sexy and 15 years younger than me. Kind of self involved and a bit immature.
I always made sure that she came first. We'd be talking dirty the whole time, but after her orgasm, she would rev it up. One night she looked up at me with those big, brown eyes and said, "Fuck me, Daddy."
I hesitated in mid thrust as I heard her. It was a kinky thing to say and it turned me on immensely. I fucked her harder and she moaned, "I love it when you fuck me, Daddy. You fuck so good." I came just like that.

After some reflection, I realized that after she had cum she just wanted to finish up. Well, she found a good way that always worked. I did not complain, at all. I think that she found that she liked being able to control me like that.
The Daddy talk continued to be her go to, but other avenues emerged that summer. One night we were going at it and she said in a strong voice, "Are you gonna cum? Cause I want you to, now. Come on, do it. Cum now." I got into it and started to thrust harder. "I want you to cum all over me. Come on, do it! Now! and then I want you to lick it all up." I grunted as I looked down at her, "Oh yeah, I'm gonna shoot it all over you."
Her arms were up over her head, making her small breasts look even smaller. Almost flat, but with nice, brown nips. Very hard and poking out. Her chest was flushed and even tho she had already cum, it looked like she was going to again.
I said, "I'm going to cum all over your titties and then suck it up off of those nipples." She came again. Seeing her face scrunch up like that put me over the edge and I pulled out and jerked all over her. It was a good load. Her little titties and belly were painted with hot, glistening cum.
She looked at me and and pointed at all the mess and said, "Well?"
The thrill of the chase was over and I just couldn't do it. "Come on, just the nipples. Ok?" I couldn't resist her, and leaned down and took her right nipple (the more sensitive of the two) into my mouth.
I gagged and she laughed, "Is that the first time you've ever tasted it? I shook my head up and down. She smiled and caressed my head, brushing the hair away from my face, "I like that you did that for me."
I know that this isn't a typical cum eating story, but it's how it all started.
