A term in the gay community used to describe a sexually aggressive male during sex who does what he wants, often without permission, and gets away with it on their submissive partner. In extreme cases, they become a “toxic top” and are often sadistic.
That dominant top choked me last night while railing me, spat on my face, and then said “I love youbitch boy”. It was hot!
Basically a DFB is a woman who loves sex while being on bottom / missionary (plain Jane) but while being on bottom she is still in full control. She’s demanding in a sexy way, and sometimes demands her man to talk dirty.
