"Ngh! C'mon... Ah! AH!" Mary Jane came for the second time in as many minutes. Slumping against her headboard she caught her breath, the redhead wiped sweat from her brow. She didn't know what had gotten into her in the last few days, no matter what she did she was always horny 24/7, it was getting to the point she was considering phoning her doctor. She got the feeling it had something to do with the bloated feeling in her belly, or her recent weight gain. Fortunately she knew she couldn't be pregnant, unfortunately that left her overexcited libido undiagnosed.

She'd been on the verge of calling Peter all night, just to try and arrange makeup sex but so far she'd managed to control herself. "He cheated on me. I'm not going to be the one who comes crawling back. Stupid White-haired hussy..." Now that she thought about it, she never actually got any concrete evidence that anything happened. Just a lot of very circumstantial evidence... "OMIGOD, MJ you are not getting back with Peter Parker because you need a booty call!"

But even as she tried to settle down to sleep, she could feel the heat creeping back into her stomach and her legs rubbed together needily. With a weary groan her hand slipped back between her legs as the digital clock turned three...

A series of similar nights finally lead MJ to one of the local bars, where she had little trouble finding a handsome young man to sate her desires. Regardless of her concerns about whatever was wrong with her, she couldn't deny it made the sex fantastic. Peter had super-strength and stamina but this... it was on another level entirely. Thanks to her newfound enthusiasm he didn't last long but she was willing to go the extra mile to keep him going. Blowjobs weren't really her thing but she needed-needed-him ready to go again. By the time the sun came up she was actually rather enjoying the lull between frantic fucking, zealously bobbing her head up and down on his crotch to get him ready. When she finally exhausted herself the poor boy had more of a limp than she did, though he thanked her effusively for the wild night as he hobbled out. MJ giggled to herself as she tried her best to prep for work, "I'll need to do that again, maybe I can get out of that shoot this weekend..." Try as she might however, she hadn't slept for over 24 hours and she'd been vigorously exercising for the last seven. With an irritated sigh, she drew the curtains and flopped back on the messy bed, groaning as she thought about the flack she'd get for missing work but passing out almost instantly regardless.

The eggs within the exhausted girl took advantage of her inactivity, releasing their last load of chemicals to keep her sedated. Over the next several hours they absorbed all the fat and nutrients she'd built up over the last several weeks... which was disappointingly little. The Hylax Larvae cringed at the girls vegetable rich diet as they rapidly grew to maturity, breaking out of their dissolving shells upon achieving adulthood. MJ groaned in her sleep, writhing on the damp sheets as her womb was stretched by the rapid growth inside her. She cried out as the first of the adult Hylax bugs began to push its way from her womb, crawling through the tight confines to the cool air of the apartment. It was tinged a light green and smaller than its parent, still soft and squishy from its hatching and birth, but it would harden within the hour and be ready to find and inject the next host with its young. Its grabbing claws were bulkier, ready to grab and not let go no matter what, and its muscular tail waved behind it like a snake. Over the next few hours the remaining eggs hatched and gave rise to a clutch of just over a dozen alien bugs. They would wait for the cover of darkness, then travel out to infect the world with their young.

MJ sighed in relief as the pressure dissipated and her tight channel closed, none the worse for wear after the discreet birth. It wouldn't be empty for long as one of her young already prepared itself to lay its clutch within her. No sense waisting a perfectly good host.
