Induces a powerful hypnotic state in the recipient

The instant you come, Amy slams down onto your cock and freezes, her head tilted back in a silent scream of ecstasy. She just stops moving, and as you look up at her, you see her eyes seeming to cloud over with some gold substance, until each of her eyes are liquid gold.

“Uhhh… Amy?” You pant. “Are you okay?”

There is no response. You try to move, but she isn't responding and you don't want to accidentally hurt her.

“Seriously Amy, I’m worried. Cut it out, will you?”

Still nothing. Her face is locked in an expression of sheer joy.

“Ummm… wake up already? Unfreeze?”

You are startled when, the instant you say unfreeze, Amy springs back to life, screaming so loudly with such pleasure they probably can hear her in the next town. Her entire body convulses in what can only be a mega-orgasm, somehow squeezing another orgasm out of you too, your cum mixing and gushing over your cock and onto your pelvis, as she moans with passion, gradually quietening until she finally has sufficient control of her body to roll off you.

“What was that?” You laugh with disbelief, once you both have your breath back.

“I don’t know,” she grins, remnants of pleasure still washing over her. “That was the best orgasm I’ve ever had in my life, by _sextillion _percent.”

“I thought you’d slow down after you orgasmed –”

“So did I! That’s not how I normally feel…”

“– and what was that thing where you froze in place?”

“What?” Amy asked dozily. “I just kept on riding you until we both came in that incredible orgasm! I don't think I could have stopped if I wanted to!”

You let it drop, though you are puzzled by what you have discovered.

“Wait, have you taken contraception?” you say.

“Of course,” she smiles dopily. “I’ve been on the pill for months now,” rolling over to stroke your chest. “Ever since I turned eighteen I’ve always been so horny whenever I thought about you, whenever we were even in the same room… I’ve wanted this for so long!”

The rest of that night exceeds your most fantastic dreams. Amy remained unbelievably sexually elevated, beyond anything you had seen, read or imagined. Just the touch of your skin on hers brings out a moan, no matter where it is, and when you lick her clit she comes instantly, without fail. The next morning you walk dazedly back into town together, missing a night’s sleep but feeling more alive than ever before.
