The two centaurs marveled at Kayla’s newest addition, the slightly enlarged mare pussy. It winked with excitement, begging to be stuffed.
“Alyssa... I grew this after you filled me.” Said Kayla, thinking aloud. “I just filled you... so maybe you’ll grow one?”
“Hmmm... maybe...” responded Alyssa, looking back at her rump out of habit, thinking she’d see anything changing, “here, take a look.”
She turned her rear towards Kayla again and lifted her slightly cum stained tail. Her anus was slightly gaped and dripping Kayla’s seed, but right below it, seemed to be swelling at an unusual rate.
“Well? Anything?” Asked Alyssa, her new horse ears swiveling towards Kayla.
Kayla didn’t answer, but instead watched. The swelling grew and grew until a large mass had formed from the bottom of Alyssa’s anus down about 10 inches, wide enough to hold her furry cheeks apart. The mass began to give way in the middle, splitting open and revealing a pink, fleshy inside. A large clitoris swelled to life at the bottom and Alyssa’s new equine pussy was complete.
“Just as I thought!” Exclaimed Kayla.
“What?! What?!” Responded Alyssa with excitement.
Without answering, Kayla dipped four finger into Alyssa’s fresh vagina.
“OHHHH!!!” Alyssa moaned aloud, nearly falling down as her four knees went weak and head went light.
Kayla rubbed the inner walls before sliding her hand down to the bottom of the opening to the clit. She rubbed it with her fingers, making Alyssa’s entire body violently quiver. Her cock sprang back to life and smacked hard off her belly. Kayla giggled at the sensation she was causing the girl.
“Ohhh~ Kayla! Don’t... STOP!!!” Alyssa screamed, rubbing her tits together as her hair stood on edge.
Alyssa’s cock continued to slap against her belly, driving her closer and closer to yet another orgasm. After a few more minutes, Alyssa gave way. Her cock exploded again, spewing another large load of horse sperm all over her fuzzy belly and legs. Her pussy burst like a dam, spraying girly juices all over her cheeks, balls, and of course, Kayla. When the liquids finally stopped flowing, Alyssa turned to Kayla, her face beat red from the extreme orgasm.
“Holt crap, Kayla... that was incre-“ Alyssa started for stopping, noticing Kayla’s new changes.
“Incredible? I know!” Replied Kayla with a giggle.
Alyssa pointed at Kayla’s head.
“What? What’s the matter?” Kayla asked feeling the top of her head.
“You have horse ears too! And a mane!” Exclaimed Alyssa with a big smile, “they’re so cute!”
Kayla smiled blushed, “Thanks, so are yours!”
The two cum covered centaur girls giggled for a moment before realizing the time.
“Oh shoot! We either need to get out of here or face someone finding us!” Yelled Kayla, in a panic.
