"Only your father has heard this and I know I should not be telling my son such things, but I always wished to know what it was like to feel a cock get hard, you know...my cock." she said somewhat sheepishly.
I felt a stirring in my pants at my mother's dirty little confession.
"First make me human again, but with a penis. A big penis, no an animal's penis! Something with huge equipment like a horse or a donkey or a"
"Bull? I interjected
OH GOD YES! she screamed out as the wish took hold and her clitoris engorged like never before.
Mom fell back against the entertainment center as the intensity rolled over her. Each passing second brought forth a pulsing surge of growth. Before too long, her clit had reached a few inches and was gaining girth in proportion. Her kangaroo features were quickly fading, which I was sorry to see go, but we were entering uncharted territory here and we seemed to be racing each other for who could get fully erect the quickest. I have to come out and say it, the vision of my mother growing a cock of her own was so exciting, I was literally shaking.
"More! MOOOORE!" she moaned in a deeper range than I thought possible.
At this point, her cock looked like a human cock, but worthy of the best in the porn industry. However, she was far from done. With sweat beading on her brow, she wrapped her fingers around the growing, pulsing shaft and began to stroke slowly, but with a firm grip. Each time her hand pulled back, her cock would extend more. Quickly, it became a two hand affair as the diameter of her shaft was too much for her small, thin hands. Between heavy breaths, her eyes rolled back into her head. She noticed me looking at her and smiled devilishly while biting her lower lip. Any trace of embarrassment in her was gone now. Clearly, this was a deep rooted desire in her.
There was a cracking sound and she whelped at it. She brought her left hand up and noticed how large and man-like it had become. She took note of her very muscular right arm as well. She was becoming hairy under her arms, on her legs and crotch. Feeling no hesitation or strangeness at this, she flexed her arms as they continued to pack on muscle, feeling her back muscles stretching as well.
She took note of two separate sensations happening just below her manhood and knew her balls were growing in. Pulsing and descending, she reached down and cupped one in order to feel it fill her hand. She lifted her massive shaft and gave her right testicle a firm squeeze. Knowing they were filling with bull sperm, her mind simplified and only one thought remained.
“I need something to fuck!”
