Porn Physics: Sexually improbable actions are perfectly possible here in this land of fantasy! Even stallion-on-inchling action causes no harm beyond pain despite the gross improbability of inserting rod A into slot B. Nor are there any sexually transmitted diseases here [obligatory pregnancy joke], meaning there are of course no consequences to having wild orgies every night.
Reproductive Control: This is a lewd world. Sex and violence are stuff you will have to face here, especially the sex. We wouldn't want you to have any accidents along the way. Or maybe you do? Either way, you will gain complete control over your reproductive system to the point of making yourself selectively fertile/infertile. Ladies get the added bonus of having little to no painful symptoms from their menstrual cycle and/or the ability to suspend it altogether. You're also immune to sexually transmitted illnesses (STIs).
Yummy: Not every guy's gonna look at you as a useless bit of fuckmeat. Sometimes they really do just want to bite down and tear a chunk off you. It's not your place to get in the way of their desire, the least you can do is make it all the more pleasant. Every part of you is delicious. A lick of your skin might be a sweet sugar or a lovely cinnamon, your soft meat juicy and tender to the taste. Even if your partner isn't out for dinner, you'll always smell welcoming and be all the more fun to kiss. And if they are, you'll find that the process of being prepared and devoured is a pleasure like nothing else.
Talent: While you may not be experienced in matters sexual, you've got plenty of raw talent, picking up sexual cues and techniques with almost superhuman skill and a readiness to learn whatever is being taught. If it's kinky, perverse, or erotic, you can learn it.
Coordination: Rosie Palms aside, you'll probably want a partner or two (or three, or ten) to really make your stay in this world the best experience you can have. Sadly, it can be quite tricky to coordinate your sexytimes with all these people. No more! This perk allows you to increase or decrease the sensitivity of both yourself and anyone you're fucking such that everyone gets to climax at the same time.
Healing Kiss: Your kiss just brings out the best in those that experience it. They feel rejuvenated and more alive than ever. Your kiss can relieve both mental and physical stress.
Synchronised Fucking: When the intentions of two people having sex are aligned, their brain waves will synchronize. If two people have a shared goal and shared desire, the pleasure they each experience will be increased as they fuck, as will the sextacy they produce. Now, you carry this phenomenon with you, being able to feel and give greater ecstasy the more your thoughts align with those of your partner.
Mrs Coffee: A demonic coffee-maker, shaped like an ebony sculpture of a lady with 'Mrs. Coffee' printed on the side. Below the sculpture is a pot of steaming hot coffee, giving off an invigoratingly rich smell. The magic of the coffee-maker always keeps the rich, creamy coffee at a properly steaming temperature while the pot is left in place, ensuring its readiness whenever you need a refreshingly caffeinated drink to energize yourself.
However, the most notable thing about it only becomes apparent once the coffee pot is put back in place. The busty coffee-maker will come to life, grabbing her thick dusky nipples and squeezing out a trickle of scaldingly hot liquid. Her eyes rolling up into her head from pleasure as she automatically refills the missing coffee, mouth open with ecstasy. As the coffee pot is refilled, her movements gradually slow down with almost imperceptibly quivers, before she freezes back into place with a final smile of contentment.
It also comes with a free mug that has '#1 Dad' written on it.
A Thousand Shades of Pleasure: Sometimes you have a partner who's better at giving pleasure than others. And sometimes you get strapped to a sex machine and injected with drugs that would make even the touch of the air an agonizing ecstasy. But there's no reason for such experiences to turn you off to the pleasures you could find elsewhere. You are capable of viewing your experiences in isolation when you so desire, without comparing them to similar memories.
Eating the best food in the world won't make all other foods seem lackluster in comparison, because you can view it on its own. Being subject to inhuman degrees of pleasure won't make normal sex boring, because you can isolate it as its own experience. It won't even taint your memories of sex, because you can disconnect them to be independent from each other.
