While Anna and Ruby resumed their breath after their last orgasm (time in which their dicks went limp and retreated into their sheaths), a young asian woman entered the bathroom and screamed when she saw the two of them. The young woman turned to run away, but Anna was quick and held her covering her mouth so she wouldn't scream anymore (thanks to her transformation she had more strength than before)
"Calm down, no need to despair." Anna said
The young woman calmed down, so Anna released her. "I'm sorry, is that your costumes are so realistic that I thought I met real monsters." the newly arrived woman said
"Please don't call us monsters. I admit that we are no longer human, but neither are we monsters." Ruby said
"What? Are you saying this is not a costume?" the woman said
"Yes, it's all real. We just transformed." Anna said
"You don't have to worry about us. I admit that I thought it was strange and I was a little scared when I started to transform, but I have never felt so good as a normal human and I am grateful for the changes." Ruby said
The woman observed their bodies and the condition of the bathroom, she noticed the cum that covered the mirror and looking between their legs she saw her shealths contrasting with her huge breasts, then asked "But now I don't understand, are you male or female?"
"We were normal women until recently, but now we are a mixture of both sexes." Anna said
"This new toy is great, just remembering the feeling of enjoying it, I'm already getting horny again." Ruby said, stroking her balls, her dick coming out of her shealth hard until it had all it's 20 inches exposed in all their glory.
"Don't say that, you get me turned on this way too" Anna said and her cock got hard too. She then saw the young woman looking from her dick to Ruby's, then she said "You seem to be interested in them. Do you want to touch them?"
The young lady did not expect that and said "I could not..."
"Don't be shy, we have already noticed that you are interested." Ruby cut off the young Asian woman's speech, approaching and staying side by side with Anna.
The young woman then took Anna's and Ruby's dicks, one with each hand, and palpated them over their shafts, making precum begin to cover their members.
"Oh, just like that ahhh ... I'm sorry I don't know your name. I don't remember seeing you at the company." Anna said
"It is not surprising since I do not work here. My name is Haruka, I am Japanese but I have lived in this country since I was 5 years old. I came here for a job interview and entered into the bathroom just to touch up my makeup when I met you." a woman said, then she pulled the horse women's cocks towards her, putting the tips together and starting to lick both.
Anna was surprised by the ease with which Haruka had approached them and was now sucking on her and Ruby's cock, especially after the fear that eka showed when she first saw them. She was enjoying having her cock sucked so much that she felt her cock throb and stiffen up, a feeling she knew was similar to that of her transformed companion since she felt her dick do the same.
It was at this time that it happened, Anna noticed that she started to get taller. She looked down and saw that the increase in height was due to her torso that was getting longer. It only stopped growing after it had gained another 4 feet in height. Looking at Ruby, her colleague had her eyes closed just enjoying the pleasure and didn't seem to notice that the two were taller.
"Hey Ruby, look down, it looks like we're changing again." Anna said
Ruby and Haruka looked and saw the glaring difference. With their current height the horse women could touch the ceiling just by raising their hands a little.
"How strange, it seems that they stretched you in a strange way. It seems that the distance between your breasts and your navels has not changed," Haruka said, as she continued to slowly caress their cocks. As soon as that was said two lumps grew next to Anna and Ruby and grew into a pair of front equine legs, so the part between their two pairs of legs thickened and formed a new belly, at which point they could not do it stay on two legs and settle on four.
They had just finished becoming anthro centauresses when there were the last changes, their breasts grew a little bigger than their heads, their dicks grew to an incredible 40 inches and their balls were the size of melons. Haruka looked amazed and impressed by the result of the last transformation of the two, who continued to have the upper part of anthro horse and now had an entire equine body like their bottom halves. Their cocks were hard under them and their tips almost passed between their front legs..
"I cannot believe it. We are transformed even more, this is incredible. I can't wait to fuck someone with this body." Ruby said
"But it won't be now. You've fucked me before, now it's my turn." Anna said and, taking her first steps on four legs, she went behind Ruby and mounted her, pushing her huge dick into her companion's mare pussy. She kept pushing more and more inward until her entire member had entered, so she was sure that the bottom part was different since with the size of her cock not even a normal horse would survive with everything inside.
"Ooohhhh this is amazing. You really put everything inside. Keep it up, fuck me the best you can." Ruby said feeling her partner's huge breasts pressed against her back.
Haruka was not just looking, she removed her clothes and went under Ruby, where she hugged a cock that was almost the same size as her entire body, rubbing herself against it while sucking on the tip.
Being stimulated in both her male and female parts proved too much for Ruby, who did not last long and came quickly. Anna give resisted much more and also came just a few seconds later. Haruka was hit hard in the face by Ruby's first cum shot, which forced her to let go of the centauress cock. She was content to keep masturbating while just watching a seemingly infinite amount of cum that came out of the cock she just embraced, reaching her own orgasm.
