[Story] You and Your Wife TF on Your Anniversary (Patreon)

You've always had a bit of a problem getting it up. And you were a little on the small side. It was your anniversary today so you decided to try to spice things up a little. You bought some pills called "Cattle Prod" from the gas station on your way home from work. It claimed to "enhance" both men and women.

That night, both you and your wife each took a dose. The effects were immediate. Your penis began to throb and swell. Then it began ache until it felt like it was going to pop. "Why the fuck did I buy gas station boner pills?" you thought to yourself. But then the pressure released. Your wife gasped when she saw your dick. It was massive. And growing. So thick. Impossibly big.

Then your wife mooed. Not like a grunt or a moan, a straight up animalistic bellow. Her nostrils flared. Her nose looked swollen? Then it ballooned outwards, darkening in color, nostrils growing thick and wide and curling upwards. Her hands shot up to cover her face. What she felt was terrifying and foreign. She couldn't tell exactly what she looked like but she could see a fucking monster snout taking up her field of view.

Fur began to sprout on both of you. Soft little hairs growing all over. Her beautiful hair fell out, revealing little bony nubs protruding from her skull. Those nubs soon grew out into big horns. She grabbed those horns and went to scream but instead she mooed again, loud and forceful.

Despite the horror of watching your wife turn into a beast, your massive cock was rock hard. It caught the eye of your wife, literally. You turned and accidentally smacked her in the face with it, your spatial processing not yet accounting for the growth. Her attention shifted away from her metamorphosis and onto your girth. She felt herself getting wet. She wanted to be fucked like an animal. She tried to take your cock into her mouth but it was simply too big. Instead, she began to lick it up and down, her wide, wet tongue providing an amazing sensation.

She looked down at her pussy. It was growing but she still had her doubts about if you would fit. She noticed something else strange though, her butthole was swollen and sensitive. Her fingers played with it. It felt so good. She needed something big in her ass.

And that's the first time you ever tried anal.
