5. Centorea.
About a week after Cerise showed up and turned our foursome into a fuckfest, there was a knock on the door. Opening the door, I was surprised to see a stern-faced but beautiful busty blonde centauress on my doorstep. She was shuffling around a bit, like she couldn't stand still, though it was obvious she was trying. She claimed to be looking for a runaway slime. I asked her why the slime would run away, and why she wanted the slime back. She looked a little nervous and deflected both questions, and simply restated her goal of recovering the slime, making it sound like official business.
At this point, Cerise came up behind me, and as soon as she saw the centauress, she exclaimed, "Miss horsey dick!!" and lunged at the human horse hybrid, who caught the slime girl in her arms and turned red as a ripe tomato.
"Cerise!" she shouted, "Why'd you run away? I've been so worried!"
"I smelled something and followed it and then I found more tasty man straws!"
The centauress was not impressed. "You could have been hurt! There are bad people out there who could do terrible things to you, we need to go home!"
Cerise backed off. "Mmm, but I don't wanna. I like Miss horsey dick, but there are two man straws here, and lots of wet girly holes..."
At this point I was giving the centauress a quizzical look, one eyebrow raised. Her composure was breaking fast, and it seemed that this wasn't the official business she had been pretending it was. So I asked her, "What is Cerise to you?"
Before the girl could answer, Cerise chimed in, "Miss horsey dick goes into heat all the time and there aren't any other horsies around so she lets me drink her tasty dick milk every day. It's super tasty, almost as tasty as yours!"
The horse-bottomed girl blushed even darker, if that was possible, and I laughed. "So that's why! Cerise doesn't seem to care about much outside of sex, so that makes sense now. Well, if she wants to stay here, I won't make her leave, but you are welcome to come visit and "feed" her any time!" I wiggled my eyebrows with a silly grin. "God knows she wipes us all out, the idea of stamina doesn't even apply to her. Anyway, I'm David! Welcome to our home!" I held out my hand to shake, and she hesitantly shook it, still blushing up a storm.
"I'm Centorea. Can, umm... can I--"
"You're staying?! YAYY!!" Cerise started pulling her inside and she only gave a token resistance. I just chuckled, stepped back, and let them through. Centorea gave a small nervous smile in response as she followed the excited slime inside.
Seeing her from the side, I got a good look at her body. Her horse half was the size of a medium-small horse, maybe a bit larger than a pony. Big enough to ride on her back, but small enough to mount from behind...
I sighed. My mind is a dirty place, haha. I also saw what drove her to come all the way here: her back half was covered in some sort of cloth (I think it's called barding?), but I could see the tip of a massive, pulsing horsecock hanging down below it. Horsey dick, check. As she passed, I also noticed that she smelled like sex drowned in an ocean of pussy, and I swear I the area around her rear end was more humid than the rest of the room. In heat and desperate for release, check.
Cerise dragged her straight to the largest bathroom and attacked the horse girl as soon as she was inside. Centorea was in such a lusty haze that she didn't even realize the door was still open as she started violently humping Cerises body. Cerise continued to cheer and squeal as the giant horse cock plunged all of what must have been 20 inches in and out of the small hill of slime that her body formed between the horse's back half and the floor.
I noticed that Centorea's pussy looked like it's between that of a human and a horse--she's probably tight enough to tug on my and Fiona's modest cocks with a vice grip, but deep enough to take a horsecock if she really stretches.
Hey, she's literally having sex in front of me, in my own house. It might have been improper before, but it's okay to ogle her now, right?
After watching for a little bit---and getting incredibly turned on--I quietly closed the bathroom door and went to find another one of the girls to relieve my pent up lust. As luck would have it, Fiona was on the couch, sitting back and watching Mia's tight rear bounce in her lap, fucking her ass at a leisurely pace. Facing me, Mia noticed my approach and grinned, though she didn't stop impaling her ass on Fiona's rod for even an instant.
I walked up, dropped trou, and watched her dripping flower petals open and close from the pressure of Fiona's cock in her ass. I pushed her back so that she was laying back against Fiona's front, which gave me a better angle when I quickly shoved my cock into my little sister's cunt and started thrusting as she tensed and redoubled her blissful moaning. Fiona and I synchronized strokes at first, then alternated, and continued switching up the pattern.
Mia was lost in a sea of bliss; no telling how many climaxes she had, or if it could be considered one super long climax. In any case, Fiona and I eventually felt the need to pump the fun-sized young woman with cum, and we both grabbed Mia's hips and pulled her down hard as we came violently inside her. She seemed delirious by the end of it, and we had to help her down to lay on the couch, where she promptly passed the fuck out with a huge grin on her face, still twitching from aftershocks.
Man, she's really getting spoiled, haha.
When we finally disengaged, we noticed Centorea standing out in the hallway watching us, biting her lip and crossing her arms anxiously across her massive chest. I just smiled and motioned for her to enter, where we found Cerise still attached to the girl's horse crotch, undulating slightly. "Hi. Can I--I mean, is it, no, umm...I want to, err--" Centorea seemed to be so twitchy and overstimulated she couldn't even decide on what to say, and all that came out was stuttering partial phrases.
As fun as it was to watch her struggle, I decided to throw her a bone. "Yes, we'd love to have you visit any time! Every day! I can tell that we're gonna get along great!"
