It's been a while since I had girlfriends, but some of them embraced my cum fetish and had fun with it. 

Jana liked to make me cum in all kinds of different ways and then played with the cum. She liked to straddle me and rub her pussy lips over my cock until I shot my cum. Then she would scoop it up, rub it into my nipples, suck it off. And cum kiss me, of course. One time Jana had just made me shoot all over her when the phone rang and she answered it. It was her dad. She just sat calmly chatting with him while my cum dangled from her face, her chin, her tits. I got hard again just watching her. 

Angie was much more aggressive about cumplay. She liked to feed me my cum, from her mouth, her cunt, her ass. She would suck or fuck me and then with no warning make me eat the cum. She didn't always do it so it was a surprise when she did. I would be fucking her hard and feeling manly and then right after I jizzed deep in her snatch, suddenly she is straddling my face, her fat cunt lips smothering me, and all that pearly jizz would be pouring into my mouth. 

It was around this time, my mid-20s, that I started playing with boys for real, and started drinking someone else's cum straight from his dick. But I remember my cumplaying girlfriends fondly because they understood how bad I needed cum, even if it was just my own.
