You cum your balls away until they are no more.

Your first warning is how the base of your dick abruptly widens with the absurd amount of semen you are releasing: your engorged-red dick belches up a messy deluge of hot cum up into the she-demon, and it is already oozing past her purple pussy-lips, but what startles you is that you keep cumming more.

You feel hot tingles in your entire sack, thrums of pleasured pulsing through your rock-hard pussy-wringed penis, and your heart flutters. You feel sweat beading across your slick brow while you lean into the demon nurse's soft naked ass, a proper pillow for your crotch, but her soft smooth ballsack is an astoundingly good cushion for your tense pulsing testicles too.

Your arms around her belly feel it slowly swell with an accelerated infernal pregnancy: it's not that squishy, and soon her clothes rip- her buttons shoot across the room!- and she presses her now wholly naked ass side-to-side into you, gyrating her hips against your root with the lurid wet sound of her hot purple cunt nastily slurping-down your entire dick like a tasty morsel.

You are *still* ejaculating! Pulses of intense pleasure flood your spine, and you're not even sure it is pleasure anymore. Your forehead throbs with the opposite of a headache and yoy swear you can feel the wonderfully tender ring of her cervix pressing on your cockhead like a kiss, then dialating open to suck-up your sperm...

... but you do feel something else. Your balls are sliding up across her sack and towards your body. They buzz and tingle and even your scrotum starts to shrink. You would have collapsed in paralytic pleasure if the bent-over demoness wasn't supporting your body with her suckling sex and supple ass, and you just surrender yourself to the incredibly long orgasm wholeheartedly.

It's minutes later- but you feel completely comfortable and relieved. Below your dick, your feel a flush of relief, a pleasant tightness and a cooling sensation you've never felt. You pull out halfway just to look-

-and your balls are not just gone. There's no trace of a sack ever having been there, with only smooth tight skin below your dick. "A lifetime's worth of orgasm. All the lives you could've made, you gave to me..." Speaks the demon nurse; your dick is completely fine, and in fact, her vaginal walls undulate to suck you back into her with surprising ****.

The she-demon is now pregnant and has her gravid belly pressed on your sister's. Corrupt purple veins streak your sibling's belly now, though. "No telling what monster I'll birth, but it's definitely yours! Was it worth your balls?" She mockingly asks, showing you a smirk over her shoulder.
