my gf said I’m cute when I cum fast

My girlfriend and I have been exploring the "mommy" dynamic for about a month now, ever since I first mentioned it. It's been really comforting to be nurtured and babied by her. I’m a virgin until last night we agreed to have sex. Long story short, she saw me struggle, I’m not even inside her yet and she leaned into my ears, saying “are you going to cum for mommy, baby boy?”and it’s triggering, sent me to another level and I ejaculated on my own hand, cupping my own cum…

I cried, because I promise her to make her feel good, while she wiped my cum from my hand, using wet tissues, fingers by fingers and kissed my forehead. No idea why, but I just had to get it off my chest lol.
