Phone Sex Got Out Of Hand

So I was soaking in the tub after an extremely frustrating week. My girlfriend called and one thing lead to another and the next thing we knew it turned into phone sex.
Unfortunately, the stopper in my tub doesn't work the best so the water drains slowly even when plugged. By the time we got started it was already pretty low.
She started off like we do a lot of times if we aren't in a rush. She teases me by telling me all things she wants to do to me. By telling me what she's doing to herself while moaning. The catch is that I can't touch myself until she says so.
This little game gets me absolutely dripping all over myself every time. I mean way more than I feel is normal. The precum pools on my stomach, slides down my sides. My dick visibly throbs.
I was telling her how much of a mess I was. She told me to rub it all over myself.
I did and I loved it. It was so slick and pleasant. I was able to cover my whole stomach and chest, swirling my slick fingers across my nipples for a while. It just kept coming, I didn't know there could be so much, granted a little can go a long way. I took it up to my neck, my face, my lips. Then I moved down, my balls, the top of my legs, even between my legs down to my ass.
I still wasn't allowed to touch myself, I actually thought I may just cum from her voice and what I was doing.
The problem was, I was wet from the bath still, the water was all but drained and I was getting cold.
I had to pee but I didnt want to stop what was happening so I just held it.
But there was a breaking point.
At first just a little shot up my body. Probably because I was so horny and so messy...but I didn't care. I just let it go, she wouldn't know anyway (although I'm curious how she would have reacted if I told her). It shot up, showering my stomach, chest and even hit me in the chin and just under my lip. In the moment, it was driving me crazy and I spread it across my body with all the precum. I even licked my chin out of curiosity, it was pretty much tasteless.
When she finally said I could touch it, I shot my load so hard it hit me in the face.
I immediately felt disgusted with myself after. I don't know if I'll ever do that again.
I have, however, experimented with precum since. Like rubbing a piece of candy against the head while it's wet and then eating it. I don't think I could bring myself to do that with actual cum though, especially because I lose all interest in anything like that after I cum.
