She listens and tries to help

Trish takes a while to process everything. You certainly can't blame her. Finally she presses her cock down firmly against her leg, her hands keeping it out of sight. "John... wow. John," she says more to herself than to you. "I wouldn't have believed it, but you know too much stuff about our school and things only you or your sister should know."

She grips her shaft a little tighter and moans. "Fuck! God fucking damn it! I finally find a beautiful girl crazy enough to stick with me and this happens."

"I'm sorry," you whisper. "I wasn't trying to lead you on. Just one thing after another."

She sucks in a deep breath and says, "I know, I see that now. But damn!"

"I understand how you feel - the last few days have been really something for me too. But if it helps I really would like to help you lay those St. Cocktease bitches."

Trish bites her lip and her arms and legs shiver. Once she recovers she says, "Listen John - there's only one way this will work: you've got to blow me. Now!" Her hands pull away and her engorged shaft slaps against her belly, oozing unnatural amounts of precum everywhere.

You suddenly realize that those runes on her back might be doing far more than making her fertile. Trish starts to stand, looking at your naked body with burning lust. Taking her advice you lunge, pinning her back against the soft earth and wrapping your mouth around her steaming hot pole.

Your hermaphrodite girlfriend lets out a mad, animal moan and tries to shove all nine inches down your throat. Instead you hold her down and slide your lips up and down her shaft, licking away all that tasty pre. When you suck on her cockhead you're surprised to feel a steady stream of hot pre drooling from her cockslit, like you're sucking her cum up through a straw.

Trish keeps rocking her hips and you ride her, keeping control but allowing more and more dick into your mouth. Finally you can resist no more and you take her right to the root of her amazing cock, your tongue teasing her balls. With that Trish gives you what feels like a glass full of cum, injected straight down your throat and into your stomach.

"Fucking don't stop!" she pants. "I... I can't control it. You suck till I'm done." Even as she finishes speaking and her head drops back against the clover you see her cock start to harden once more. You're impressed by what those runes can do but whoever made them also made a mistake - you're actually horny enough that you can keep up with Trish.

It takes what feels like hours of you blowing Trish and jilling yourself off while she recovers. Your stomach gets so full that you worry you'll have to start spilling Trish's tasty cum on the ground rather than swallowing it like a good girl.

The end only comes when Trish passes out after screaming, "Oh God yes!" for about the fifth time tonight. For safety's sake you fall asleep with your mouth wrapped around her now flaccid cock just in case she reawakens.
