Some science experiments of your own.

"So these feathers you're going to give me," you muse, and grab one of the albums from a nearby table. "What do they do?" You kneel in front of her and open the book so she can see it, then you point to one of the feathers. She's got the strength in her neck back you guess, because she turns her head a little to look better. You left her ass exposed to the bright light of the room of course, and now glancing back down her body at it you feel yourself harden. Your cock is bulging in your pants, wanting out.

"That one is an... it makes you dizzy."

"And this one?"

"Soporific, it makes people sleepy."

"And which ones," you say slowly, "are aphrodisiacs that work on girls. That will make them cum? That will really help me?" She bites her lip, and her beautiful hazel eyes look up at you pleading with you not to make her screw her fellow fighters over. You put the album down for a moment and unbutton your jeans, pushing them and your underwear a little way down your thighs. Your prick leaps up and in a few strokes it's thick and hard as granite. The head gleams with precum and Felicity looks at it stunned. "You aren't even wearing panties," you remind her.

"It's just... I don't like to..."

"But Felicity... you're so fucking gorgeous," Christ, she's blushing, "and with no panties... that perfect pussy, just begging to be fucked..."

"It isn't begging for anything!" She suddenly closes her legs... getting more strength back and flexing her fingers, her hands bound together above her bare ass.

"Which ones are the aphrodisiacs?" You stroke your shaft again and if possible, it seems to thicken even more. You stand and take a step to move behind her.

"The grey ones!" she says quickly. "The grey ones work better on girls."

"That's great," you stop, reaching down to grab the album and flicking through it until you find a page of what look like pigeon feathers. "These ones?" She nods, looking up at you nervously. She's a 9.5 out of 10 you realise, and she's helpless before you. You can't just let her go. "Let's see if that's true."

"No! No! What are you doing?" she gasps as you move around and kneel down behind her again, your cock jutting out in front of you.

"Confirming that with an experiment," you answer, and gently prick her with one of the grey feathers, right in one of her ass cheeks. You watch the serum enter her and then kneel back. You **** her legs apart again, and though this time she has the strength to fight back, she's not strong enough to stop you. You expose her pussy and enjoy the view, stroking your shaft while she starts to breathe more and more heavily.

"No! No! What did you do?!" The perfect woman comes apart a little more.

"I think it's called a taste of your own medicine." Fuck, that perky little as is too much. You need to feel that rump against your cock. You lean forwards and, supporting your weight with your hands on either side of her shoulders, you start to grind your throbbing, dirty cock into the divine valley of her ass.

"Oh fuck, oh fuck, it's ok. I can control this," she's talking to herself. Goddamn, that ass feels good against your prick... the skin is so soft and yet it's so perky and firm... "Ooohh! Aaahhn!" Shit! She's arching her back and pressing up against you! Grinding back.

"I thought you looked too good to be grinding your ass against a stranger's dick," you chuckle.

"No... No I'm not! I'm not doing that!"

"Oh you are!" You stop moving and now it's just her, consciously or unconsciously she's working her impossibly perfect ass against your rigid manhood. You lift your self up, and watch as her ass humps up as much as it can, trying to follow you. She's losing control more and more. When you pull her ass cheeks roughly open her flesh feels several degrees hotter. Perspiration is beading the small of her back below her hiked dress, and of course when you look between her thighs her pussy is flushed a hot pink now.

And when you press two fingers to it it yields immediately, and sucks you in to the hot, wet interior of a Goddess who is rapidly being reduced to a slut.
