Patricia leads you to a party being thrown in some random guy's house, where the music is pumping and everyone is jumping around. She drags you over to the dance floor and you gradually get into the groove, following her example as she bounces around, which must be uncomfortable since she stops after a few minutes.
"Damn, I need a few minutes. Mind coming with me, big guy?"
She takes you into the bathroom clearly marked for the ladies, but no one's looking, so they don't care. Inside, Patricia unlaces and removes her boots. She then tries to massage her sore paws to no avail.
"Guess I'm got no choice." She takes out the jar of cream from her bag and puts some on her paws and legs. Within seconds, they look exactly the same like those of a human woman.
"You want some? I can only suspect those hooves of yours are causing just as much discomfort."
She's not wrong. You take off your shoes. But then Patricia notices something.
"Stay still."
She comes over and unzips your pants, and something comes springing out. It's your cock, which is now so fat and thick it threatens to tear right through the fabric. Your balls are so swollen with latex sperm, they practically drop to the floor.
"Man, for a latex horse, you sure do have a lot of semen backed up in there. I wonder..."
She grabs your penis and starts tugging on it. You quickly climax, and she only barely dodges the small stream of cum that shoots out of you onto the floor.
"Odd." She dips her finger in the puddle and puts it to her tongue. "Vanilla. Someone actually put flavoring in your semen."
Your whinny a little. You need her to get you off.
"Alright, alright. I guess I can see how much of this gunk I can suck out of you..."
With that, she swallows your cock and sucks it. You find yourself rising up, standing on your own two hooves, and putting your hands on the sides of her head to hold her close. Soon, you cum again. Patricia keeps your dick in her mouth, swallowing your load as fast as she can, and then resumes sucking.
She keeps at for the next hour and an half, until your balls start to shrivel up and your cock goes flaccid. You then push her away, and your cock pops out of her mouth.
She looks pleased. "Got to say, drinking a horse-man's semen for a couple of hours is quite the experience." She pats your cock. "Looks like you're gonna be impotent for a couple of days until your testes can make some more spunk."
Just then, you notice purple fur sprouting on her arms. Her ears are beginning to poke out.
"Guess that cream's wearing off. I've got a place where we can stash these clothes, if you're ever in the mood to try this again, my little stallion."
