"Are you sure you want to?" Karkat asked, his voice barely over a whisper for once.
"mhmm" Nepeta purred, laying back on the bed. The small talk ceased as their lips found each other. they began moving hurriedly and with passion, sliding hands down to their nether regions without hesitation.
"Fuck" he grunted as he felt his hands begin to shrink up.
"Nnnnn, AC wonders if the attractive man on top of her is close" she moaned as he pushed a finger into the softness of her nook.
"CG is um, excited? fuck it the answers yeah" the way her hands were working over him was beginning to make the process faster, he could feel his back scrunching up and turning redder.
"I want you in me" she gasped as he continued to work his fingers expertly.
"I'm so close" he gasped as his legs began shrinking, the final stages coming forth as his head was brought in closer to his body, hands separating into only two segments like claws. with a moan he turned fully into the crab. she spread her legs and gasped at the texture of him as he crawled towards her nook, spreading her as gently as possible and crawling in. She arched her back, near screaming from pleasure as his little clawed feet poked and prodded, going farther and retrieving her egg. He snipped it out of her with his claws, earning a gasp and a rush of blood. crawling out quickly it was not fast enough, he turned back into a troll halfway through, she screamed in pain as she split, Karkat held the fertilized egg out in front of him, not daring to let it slip away now.
"K-Karkat?" Nepeta whispered faintly.
"Nepeta I'm so sorry" he cried as the blood continued to leak from her,
"I-I hope our child has, your eyes" she murmured before passing away into realms further than the dream bubbles. Sobbing Karkat clutched the egg, still unable to get out of Nepetas body,
"I promise I'll take care of you" he whimpered, "I promise".
