Novices and newbies discussion

I strapped my cage back on last night after months away. I jolted awake at 1:30 AM, absolutely bursting with desire. My girlfriend was fast asleep. In the dream, we were messing around and she gave me a blowjob while I neared climax. She paused then told me to lie back so my seed could spray everywhere (that’s what typically happens if we play without going all the way). Right then in the dream, I begged her for permission to cum between her breasts on her nipples. She was like, “No way! You haven’t climaxed in weeks; it’ll be too messy.” I replied that I’d handle the cleanup and take care of everything. Just make me lick every bit off you. Then reality caught up: I woke up rock hard. (We’ve never done this before, but I have rubbed my pre-cum on her nipples and licked it clean). I climbed out of bed intending to head to the spare room for a solo session. Instead, I grabbed one of my cages and put it on. After sleeping about four hours, I woke up with pain in the cage from fighting erections. My underwear was covered in stains. But I feel like making that decision was right—locking up rather than jerking off. I don’t know how long this will last; maybe she’ll get into it. She’s pretty vanilla though. I suppose I need some help.
