High Turned Me Bi

This was back when craigslist had personals. I was 19, high and looking through all the men's ads for one real woman.
I eventually hit a point where I just didn't care and was going to take any orifice I could get.

I responded to an ad, sent my picture and got the address.
I texted him I arrived and he texted me he couldn't wait to feel my mouth. I was surprised at that and double checked the ad and realized he wanted to get sucked. At that point, I was already there and his garage door was opening so I went ahead and got out.

I walked into the garage. I had never sucked a man before, but part of me was actually excited? He was an older guy (I'd guess in his 50's).
Idk what came over me but I decided to try it. I asked him to close the garage door and he said no, he wasn't going to close it. So then I told him to pull it out as I got down on my knees. He pulled his pants down and out came his cock (I remember it curved to the right a bit).

To my surprise, I got really into it, said "oh daddy", then started teasing him with my tongue and playing with his balls, sucking and nibbling on them. I remember a little bit of his precum rubbed on my cheek. Then I just started gobbling his cock. I actually was able to deep throat him. I just did things I always like when girls suck me.

He put his hands on the back of my head, said "yeah, take daddy's cock son" and boy did I. I just became this cock slave and he used me. I let him push it all the way in and out of my throat, gurgling with each thrust of his shaft in my mouth while a spit and precum mixture leaking out of the side of my lip. His bush kept pressing into my face and his pubes were gray and felt soft.

In a few minutes, he started moaning he was going to cum but I just said "mhmm" while going up and down his shaft and swirling my tongue underneath back and forth.

His cum spurted out hard and I just let him fill up my mouth while going "mmmmm."

Then I spit it on the ground (even high didn't want to swallow it) and he said "you can come back any time."

Then I got up and left.

I've never done that before or since, but secretly part of me liked sucking that one time.
