The door with the coin

After a moment of hesitation you decide to try the door with the coin. The silver key fits perfectly and with a quiet click the door unlocks. With your sword at the ready you walk through it...

...and blink in surprise as you find yourself in some sort of shop. There are all sorts of items there: weapons, clothes, pieces of armor, potions, jewelry... It's quite a large shop, with three exits that you can see: The door you just opened is still there, so you could go back and try one of the other three doors if you want, or you could try the door ahead of you, or the small door to the right. That last one likely leads to a different part of the shop, like a storage or something, but in this place you can't be sure.

"Hello. Welcome to my humble store." A woman's voice interrupts your thoughts. You look and see that the source of the voice is an elven woman with blonde hair, green eyes, and matching green dress that reveals a little of her large breasts. At first you thought the woman was just a mannequin but now you realize that she's quite alive. "My name is Elvina. Nice to meet you."

"Oh, hi! Nice to meet you too, Elvina. I'm Anna."

"Looking for anything to buy, Anna? I have almost everything you could ask for..." The elf smiles at you.

"Well, I appreciate the offer, but I'm afraid I don't have any money..." You admit sheepishly.

"That's alright, money is not the only currency accepted here." Elvina assures you.

"Oh? What else?" You question her, curious.

"Well, there are a few other things you can offer me: For starters, if you strip for me I'll give you 5 Coins." You blush at the suggestion. "If you strip and masturbate for me I'll give you 2 healing potions; if you lick my pussy and make me cum I'll let you choose between a pack of 2 healing potions, 1 mana potion and 1 spell scroll, or a pair of spell scrolls. And last but not least, if you let me fuck your ass I'll give you a special piece of clothing for free." By now your face is bright red. "Of course, if you would like to suggest something else I'll be happy to hear your offer..."
