By now, the hormones coursing throughout your bodies could not be suppressed any more. You had denied yourself long enough to proceed with the copy upgrade, and now that your mental link was stronger, so too was the shared feeling of horniness. Standing outside the chamber with your altered female body, all six of your dick-nipples sported rock-hard boners, matched by the other nine dicks standing at attention above your crotches. Your various vagina-nipples and pussies weren't any better off, all of them moist to the point of nearly dripping with arousal. As you lifted your arms to start fondling your boobs, you couldn't help but raise all of them in sync, resulting in groping all eighteen at once while your bottom-most pairs of arms grasped at the air.
Realizing you could help remedy the situation through the use of your other two bodies, you approached the body that was masturbating with intent to help guide your free arms and train them. Reaching out to the lowest arms on your left torso with your main body and mirroring the action on the right torso with your female body, you gently grabbed your wrists and guided them to a pair of cocks and a pair of vaginas. As you guided yourself to begin fingering your cunts, a sharp wave of pleasure reminded you that you had also doubled the clits in each pussy. Satisfied that you got your side torsos a bit more coordinated on your transformed body, you then approached the middle torso with your female body. However, instead of guiding the free hands towards more self-pleasure, you instead guided one hand to your female body's pussy while guiding the other arm to wrap around your back and pull you in close.
The height was perfect for your top row of breasts to line up with your female body's nearly-matching pair, and you instinctively opened your lipples so you could start sucking your other body's nipples. The feeling was both incredibly strange and fiercely arousing, your mind confused at the feeling of having your nipples sucked while being the one doing the service, twice. To complete the deal, you leaned in and began kissing your middle head, once again reveling in the feeling of experiencing both sides of the same kiss in tandem. You could feel your middle torso's dick-nipples poking your other body's stomach with its boners, which incited you to begin gyrating your hips and rubbing back and forth against the dicks. Meanwhile, your male body got comfortable with your left torso, and you were thrusting your original dick into that torso's middle pussy while you teased the two clits inside one of your vagina nipples.
Higher and higher the pleasure grew until you came all at once. Your self-pleasuring right torso let loose, ejaculating into the air and letting the cum fall harmlessly onto the floor. Meanwhile, the dicks sandwiched between your girlfriend-body and your middle torso coated both your bodies in sticky cum, having nowhere else to go. And while your male body came directly in your left torso's middle pussy, you knew it was fine from what your girlfriend told you. Exhausted and basking in the afterglow, your original body and your unaltered female body staggered back and took some seats.
Contrarily, your transformed futa body seemed to still have energy left. Flexing your arms experimentally, you noticed that you were already getting much more used to the body, and could control it a lot more freely. With a little concentration, you turned your right torso's outer heads to face the center head, then brought them all in for a sloppy three-way kiss. Intoxicated, you then had a pair of heads on each of your other torsos turn towards each other to start two more kisses. Already the arousal was building up again, and your once again brought several of your arms up to begin fondling your breasts and playing with your altered nipples.
Knowing that you set the parameters with a very specific act in mind though, you soon guided a pair of hands on each body to grab all your dick-nipples. Then, aiming them upwards, you maneuvered them around a bit so that they slid into the vaginas on the breasts above them. Suddenly penetrating and being penetrated six times at once hit your senses like a truck, and you could feel your legs trembling from the pleasure. Turning your left and middle torsos towards each other, their heads stopped kissing each other and you looked yourselves in the eyes six times over. Embracing each other, you pulled in close as your top pairs of breasts began kissing each other and your six heads started three pairs of kisses with the heads opposite them. Your remaining free hands all dove down to stroke your neglected dicks and finger your pussies. Again you felt the pleasure welling up within you, stronger than even last time. Unable to hold back, you screamed with nine voices in harmony as you came repeatedly with all your penises and vaginas at once, your vision briefly going white from sensory overload.
After that, you passed out for about twenty minutes. When you woke up, you...
