Isn't virility the term for men? No matter! You eagerly sign the paperwork without reading a single line and are more than happy to do whatever it takes.

Later that night, you sit up in bed in the medical facility you're staying in for observation. You took a pill a couple of hours earlier, which apparently contained some combination of nanomachines and artificially created DNA that the nanobots used as a blueprint to fix various issues in the body.

"L-- Let's do this..." You grunt and let out a low moan as your insides quiver and convulse. Unable to maintain any semblance of balance, you fall to your back and moan as your chest tingles and begins to swell while your nipples angrily pulse. "Mmm-- aggh... W-- what the fuck?" You gasp, gazing toward the budding breasts sprouting from your upper body.

Your hips and waist crack and begin to reshape, your ass plumping up while all facial and body hair falls out in clumps. All the while, euphoric ripples shoot through your increasingly tender and sensitive frame, with most of the sensation manifesting in your quivering, tightening crotch.

"Mm-- ahhhhhh!" You cry out as your voice heightens in pitch, taking on a girlish quality. In a state of confusion, you cup your growing tits in awe, feeling as they expand and fill your hands.

"This-- isn't right!" You squeal again, your insides churning. Your cock and balls throb and shift as your new vulva slowly takes form. The sensation of your testes ascending into your pelvis is alien and bizarre, and so is the feeling of your scrotum splitting into moist folds and your dick receding into a throbbing pink nub nestled amongst the folds.

"N-- No!!" You cry out, grasping for your junk only to find a moist, feminine mound. Brushing upon your clit, a powerful burst of pleasure shoots through your steamy nethers, causing you to moan and writhe, arching your hips up while your tits further grow.

Your hair extends outward while a fluffy white tail and ears sprout from your backside and atop your head. It happens faster than you can react, and you're soon left panting and trembling in a state of confusion. "W-- what?"

You sit up and look at the mirror, blinking in disbelief as you stare at the blue-eyed, busty cat maiden reflected. You cup one of your breasts and blush furiously as something occurs to you. 'They really did mean fertility...' Parenthood would mean motherhood for you.

The next day, you squeeze into your new bra and shudder from the sensation coming from your nipples. "Mmmm..." You blush and take a deep breath, sliding your panties up as they snap into place, caressing your sensitive, feminine flesh. "Ahhh!" A hot tingle shoots through your pelvis, followed by a profound sense of emptiness. Glancing toward your reflection, you can't help but think, 'With a body like this, finding someone to start a family with won't be an issue.'
