I was willing to trial an experimental drug and the main side effect I've noticed is my cum supply has been doubling day after day. Even the size of my cock has been growing. I've been fearful to fuck my partner because like what if it can affect her? What if it makes her grow in ways I can't help?
She's been begging to breed and I just cant help it anymore, I cant help but imagine how I could change her small petite body
Listen, I don't want to be the one to break it to you, but if she's specifically begging to be bred, then it's likely that you've already changed her. Maybe not physically, not yet, but being in close proximity to her has already rewired her brain to beg for what you've got.
What you're experiencing is a lesser known side effect of those kinds of trials. Most people focus on the sheer volume of cum their producing, which is understandable, but it's not just making you cum more. The drug is making your cum more potent, more virile. You probably haven't noticed it since your hormones don't respond to it, but your cum is pumping out pheromones by the barrel-full. That wastebasket in your room that's packed to the brim with bloated condoms and yellowed tissues is sending out a constant signal that you are more than capable of filling a woman's body and making your seed take root.
Your girlfriend might not even realize that's what she's been smelling; all she knows is that you smell goodâyou smell really good. If you were to go into her room, I wouldn't be surprised if you found one of your pairs of boxers tucked under her pillow, her vibrator and other toys easily within arm's reach. She needs you. She needs your cum. As the trial progresses, she'll become more and more desperate, driven further into her heat as her body demands to be fucked and filled and bred and, if you don't give it to her, she'll be forced to take it.
The pregnancy will be transformative for her. With the potency of your cum pushed through the roof combining with the heat you've forced her into, we're talking quadruplets, minimum. Over nine months, you'll watch her body change not too differently from how yours has. Her hips will widen, giving her padded ass and thickened thighs the perfect sway to announce that she is made for motherhood. Her tits will swell and engorge, surging through cup sizes beyond her wildest dreams, quickly filling with milk that she'll spend hours each day just trying to empty, pumps sucking on those swollen, leaking teats. Her belly will grow slowly, at first, but as the months go by, it'll push outward more and more until it completely dominates her figure, sticking out of every shirt she owns and entering a room moments before the rest of her catches up. It'll seem like a miracle that she can walk at all and, as the end nears, she might not be able to, simply beached under the heft of her swollen, gravid body.
At this point, with the way things have gone so far, that outcome is nearly inevitable. So your only choice, really, is to give her what she wants now or torture her with desire for it until she has to tie you up and take it. Better to get it over with now in a way you can control. And, besides, just think of how intense your pheromones and cumloads will get after nine long months.
