He agreed with a condition

"OK," he said, "But nothing queer. If you're gonna be Mom then you're gonna be Mom. I ain't fucking no man, whether they're a parent or adopter or whatever. This big black dick only goes in bitches, OK?" he grabbed at his crotch and I couldn't help linking my shiny red lips, "So, as long as you don't try and be a man at any point, then, yeah, I'll admit, a chance to get as close to screwing Mom as possible kind of gets me off."

"Alright then, honey, I'm your Mom, what do you want Momma to do for you?"

"How about you just reach over here and feel what you do to me, Mom?" my adopted son replied.

His left hand was still on his crotch, but with his right he reached over to where my hands were crossed daintily in my lap and pulled my left hand over to grab where his was. My dainty fingers were dwarfed by his strong black grip, but not half so much as by the huge hunk of muscle I felt quivering in his pants, stiffening just at my touch.

Without asking for permission, I unzipped his pants and he pulled them to the floor along with his underwear. His black dick was semi-stiff already. Even though I had seen it already that afternoon, I was still overawed by the sight of its dark purple shaft as it sprung free from his clothes. How could a sissy like me have ever raised such a man?

"So big..." I gasped, running my fingers along it. Despite all my years of dressing as my wife, this was the first cock but for my own that I had ever touched.

"And you're only gonna make it bigger, Mom," Keenan said.

Grabbing me by the back of my head with my long blonde wig, my big black son pulled me into him. With my pale fingers closing around his black shaft, he pulled my lips to his and kissed me. Of course, I had kissed him when he was a little boy and I'd put him to bed, but never since and this was a whole lot different. He had an overwhelmingly manly musk and, as I enhaled, his mouth clasped over mine. He had all the power, holding me tight to him as his tongue pushed between my full, pouting lips and explored my mouth. In my hand I could feel his ebony love muscle getting stiff. Meanwhile, beneath my skirt and panties my own tiny white equivalent was hardening too.

Breaking from the long kiss, I pulled off his shirt, revealing his chest rippling with muscles. Letting out a sigh of desire, I ran my right hand over his washboard abs, black flesh glistening with sweat, while my other hand jerked at his monster sausage.
