"Alright Susie," Alex said, "You can release now." The moment the words left her lips, her lover suddenly cried out in more ecstasy than she had ever heard before. A torrent of juices erupted from her vagina, flooding and soaking into the bed sheets as she screamed loud enough to rouse the dead. The release and relief Susie felt was unbelievably wonderful, although she wished her torment could have lasted a few seconds longer.
"Susie? Babe?" Alex asked her panting companion who was still blushing from the afterglow, "You doing okay?"
"That was the best orgasm I think I ever had!" Susie smiled, "This implant... this implant is gonna change so much about our relationship... and I'm not even a Stallion yet!"
"Thank goodness everything seems to be working as intended," Dr al-Zawahi smiled and nodded, taking down some notes, "Now if we could test the sleeping protocols, please?"
"Okay, Doctor," Alex nodded before turning to Susie, "Alright then, honey, go to sleep for me."
"After that orgasm," Susie said, "I don't think I'll be able to..." The patient suddenly felt her whole body shutting down as she closed her eyes and gently went to sleep.
"Now wake up, Susie," Alex commanded. After a few moments, Susie's eyes fluttered open and the patient was awake once more.
"Huh," Susie huffed, "Well stick a cone on my head and call me a dunce. Here, let me try going to sleep by... myself... um... Holy cow, I legitimately can't make myself sleep! I'm one hundred percent at the mercy of Alex! This is... this is kinda awesome!"
"Excellent!" al-Zawahi smiled, "Both protocols are working as intended! Fun fact, we actually use cybernetics to implant the muscle memory and instincts into our patients, so knowing we can make cybernetics like this is more than a little exciting. With that done, we can get to the business of optional cosmetic features and deciding what kind of semen Susie will produce."
"Well... what're our options?" Susie asked.
"You'll like this," the doctor smirked, "You get to choose your hair color, your eye color, and even the color of your lips and nipples! We can do any color under the sun, from electric lime green to hot pink to baby blue! Any color you desire! We'll even do the cock head if you like. We also have the option to make your new breasts lactate if that's what you're into, but it is an extra expense. As for what kind of semen she can make, you can pick between horse semen or human semen. Horse semen can be sold to breeders at a premium, but human semen tastes better to Dorses. Depends on what market you want to cater to, really. Just fill out this form here with whatever cosmetic options you wish to take. After that we can get started on the operation proper."
