Marina was about to flee the scene when some people held her tail and prevented her from leaving the break room. Most of the employees left the room because their break time was over, leaving only the three who held her tail. Those who stayed behind were Eliza (one of the cleaning ladies), Ivan (one of the security guards) and Laura (her boss's personal secretary).
"We are not done yet." Laura said passing in front of Marina and starting to stroke her cock again, Eliza joining her next. Ivan also released her tail, bent down behind her where he found her pussy hidden behind her balls.
Marina couldn't help getting hard again, with that Laura and Eliza started using their mouths, each sucking on each side along the shaft of her dick, meanwhile Ivan stuck a whole hand in her pussy. In a short time all this stimulus made her come again, further increasing the cum dirt in the room.
Even after having made her come again, Marina was prevented once again from leaving the room, this time with the three of them standing in front of her. For them to do this, the anthro horse woman noticed a big bulge in Elisa's pants and Laura's leather skirt, just as the breast of Ivan's uniform seemed to be stuffed.
"You still won't leave here, you will serve me to debut my new toy." Eliza said, unzipping her pants and popping out her new dick
"That's right, it's not just you who are going to have to play with our new toys just like we play with yours." Laura said taking off her skirt and panties leaving her new hard member exposed too. Ivan said nothing, but the buttons on his shirt popped, making it open and making it clear that he had a pair of E-cup breasts now.
"You are perverts, right. You are even transforming too." Marina said
"We realized. I was a little surprised when I noticed my cock growing, but it feels so good and I'm so excited that I don't mind changing." Laura said. Ivan and Eliza also commented making it clear that they were enjoying the changes that were taking place with them.
The three employees took off the rest of their clothes afterwards and put Marina on her hands and knees on the floor. Laura went after her and aimed her cock in the horse-woman's ass, Ivan went under her and with his own hard cock found her pussy, which he fucked while keeping her horse cock between his new breasts. Eliza then said "Now I want you to bend over and suck my cock." which Marina was delighted to do.
While she was being fucked by the trio, Marina saw that Eliza's body be covered quickly by fur just like hers, only with a slightly different color. After this happened she noticed the three of them start to grow and change shape inside her, at the same time she realized that she herself had started to change too. Marina couldn't see what was going on with her, just imagine what for what she felt. She felt her body lengthen (which became clearer with Eliza having to take a few steps back) and some things grow in the middle of it along with an increase in the weight on her chest and between her legs.
Marina felt the new parts that grew in the middle of her touching the floor she felt Ivan put his legs around her hips and thrust a few times before stopping his cock all inside her and coming. Soon after, Laura and Eliza came, too, making her reach ecstasy and have another long orgasm, now longer and more intense than the previous ones.
After two minutes cumming Laura's, Eliza's and Ivan's had finished, which allowed Marina to see the results of the new transformation she had undergone. The most striking part was that her bottom half had become a complete horse body, making her a centauress with the body of an anthro horse-woman instead of a head. Other than that her breasts were even bigger, clearly H-cup now, and her cock had doubled in size while her balls had tripled.
Marina's orgasm took a few more minutes to stop cumming, at which time she saw the other three, who were now all hermaphroditic anthro horses like she was when she entered the break room, leave the room. When her orgasm finally ended, she relaxed a little, certain of one thing. Her transformation was contagious.
