Your Dick is Growing and Your GF is Becoming a Cow (Patreon)

An entity appears before you and your girlfriend. It said it had the power to make your deepest sexual fantasies come true. The only catch is that both of you can't tell each other your desires beforehand.

The two of you talk it out and agree to do it. "It is done," the entity said and then it vanished.

You immediately get an erection. It feels like the hardest one you've ever had in your life. The blood in your cock is pumping so hard. And it starts to feel uncomfortable. Your dick is pressing so hard against your pants.

Meanwhile, your girlfriend is rubbing her face. She sneezes and then her nostrils flare. But they don't stop flaring, they start expanding. What looks like snot or some other moist substance starts pouring out of her nose.

"Oh my god!" she screams and covers her face. Then a loud, deep "mooooooo" comes out from behind her hands. There's a pop and a crunch and then her nose and mouth start to protrude further from her face. Short black and white hairs start to sprout all over her.

During this time, your dick has grown insanely large. It's literally bigger than your arm, thicker than your leg.

"WHAT THE FUCK IS YOUR FANTASY?" your girlfriend screams at you.

"I've already guessed yours!" you yell back. "Was my cock not fucking big enough for you?"
