My mom was a no-nonsense goal driven person. I was more like my dad, go with the flow and aloof.

Mom reconsidered her life goals, habits and way of living several times a year. Dad stuck to trying to eat more greens and saying "yes dear". Their philosophies showed on their bodies. Dad had a typical dad-bod and practical but ill-fitting clothes, often stained, and with patches of holes in it.

Mom was a bombshell with a knock-out body, looking like a woman in her early thirties, and not her actual age of 51. She had also recently had massive gains in her biceps, growing them a lot, flexing them to me and dad, as well as getting washboard abs. This was as she put it:

"A blessing from my fancy new balls!"

I don't pay attention to the news a lot. I still live at home at 24, and between my job in a grocery store and gaming all of my spare time I don't have time for it. But apparently it was much easier to get a partial sex-change now, the "futanari-treatment". Women could through a minor surgery and taking a pill daily grow a functioning penis and balls (producing sperm and testosterone). Men could do something similar and grow a functioning uterus, vagina, and tits, with the aid of only one minor surgery. It was much more popular amongst women than men. Apparently career-women wanted to become more aggressive and dominant though the hormones the balls produced. That's why she had chosen to get the surgery.

At least that was what my mom told me and dad at the dinner table when she came home from the surgery.

Dad seemed disappointed, slumping a bit in his chair. He had not been consulted about his wife's decision to grow a cock. But he did not voice his discontent.

Mom grew a lot more dominant in the household after this. And her muscles and her bulge grew. Before her surgery I had frequently heard my parents make love, but it grew silent now. And it seemed to take its effect on my mother the most, her throbbing cock barely contained by her skinny jeans.

Dad seemed to avoid her, and took more interest in me, occasionally barging into my room asking: "Are you winning son?"

Sometimes I was, sometimes I wasn't, you can't win at Animal Crossing. He would often stay and watch for a bit. I didn't mind, though I changed the games I were playing to more family friendly ones.

On a fateful day my mom had home-office, and I had the day off. I decided to play a hentai game I had avoided playing since my father had started barging into my room. But with him in the office and my mom rarely entering my room I took the chance and booted it up. Scantily clad hentai babes soon filled the screen and their moans my ears. My headset providing great sound.

My dick was growing hard, and i turned towards a table drawer where i kept my lube. I froze. In the door opening to my room from the hallway my mom was watching the screen, holding some folded laundry in her hands. A faint smile creased her face when she spoke: "Are you winning son?"
