My first time was unplanned. We had not given ourselves completely to what would become our first black master, although things were certainly going that way. He'd fucked me in front of my boyfriend several times a week over the month previous, getting more controlling in his treatment of us both, subtly moving from swinging to dominance.
That night, he ordered my boyfriend to sit in a corner, naked, but not allowing him to stroke. Laying me down to take me missionary, he pulled off the condom after a couple of thrusts. He told my boyfriend to shut up, then looked at me and just said "Problem"? I mumbled out a "No sir" and he slammed back in me.
When he came, it was the first time anyone ever had finished me bareback, and it felt like I had a compass spinning in my head for life, that finally pointed true north. I knew what I needed.
I cried for a half hour afterward, but also laughed, so overjoyed and overwhelmed. After the real man left, my boyfriend held me, and I cried on his shoulder, telling him this was my life, and he could accept me doing a lot more of it, or leave.
