Super Sex Powers!

"Well," says the first alien, "we've been watching the exploits of mankind in the sack for a while, and we've decdied to give the whole deal a kick in the pants."

"So we drew lots," says the second alien, "on who would recieve our high-tech sexual augmentations, and ten people, including you, won!"

'Holy shit!" You say, "What sort of improvements?"

The list is fairly complex, but roughly reads: Near infinite ejaculation capapcity, enhaced genital endowments which get hard and stay hard as long as you want, nerve enhancements for better orgasms, and specialized "nodes" to make the women come practiclayy on command, not to mention harder thatn usual.

Obviously, within a few seconds, you've accepted, and within a half hour, you've been upgraded, and you get beamed down to earth, to where the girls are still waiting as you left them!
