I went through an anti-penetrative sex phase in college. I was constantly horny, but refused to entertain a sexual interaction with a man involving my pussy. The only sexual activity that excited me, ironically, was the prospect of sucking dick.
I daydreamed about going down on men, licking up and down their shafts. In my fantasies, our interactions were one-sided: I would service him, drink his cum, and get nothing in return. I spent months getting myself off to those mental images of a man simply using me (namely, my mouth) and walking out before I could wipe my mouth.
One night, in my junior year of college, I went for it. I had been messaging a man who indicated some interest in meeting up (for a hookup, that is), and I very bluntly offered him a blowjob, and nothing else. He agreed, and was at my apartment within two hours.
We exchanged pleasantries, gently kissed and explored each other’s bodies, and I sank down to my knees as he perched at the edge of my bed. He untied his pants and pushed his briefs down to his knees, and I immediately reached for his cock.
