The receptionist

The brunette who works the desk at your apartment complex is a gold-digging slut. She's barely even useful for 3/4 of the residents but she's got a reputation for doing anything in exchange for expensive dates and gifts.

You duplicate a stack of money and go down to chat her up. You brag about having a new job and show some cash, she comes alive and flirts a bit, you walk off as though you didn't notice--and you've got a second girl "in memory."

In your room, she's as blank as the blonde. She adopts a pose that gives the best angle of her ample cleavage and short skirt, but she's waiting for you to take the lead.

You just got laid, you can wait a minute. You test her with some logic puzzles and physical challenges.

She can't do a backflip and she can only slowly read, but she instantly understands it when you speak. You can play audio clips of other people speaking and she responds to them if you ask her to. It is difficult to figure out her limits.

Physically, she's not as curvy as you thought. B-cup at best, her bra and her choice of blouse were doing a lot of work. Nice ass, more muscle than fat. She's not just "fit," she's more athletic than she looked while dressed. She's a track athlete, maybe.

She was also wearing more makeup than you realized. You have her wash it off and she looks completely different. She's not so alluring but she's still cute in a way.

It unsettles you a bit. It reminds you how people are just people, and the judgements you have about them are sort of unnatural. We all have similar needs, similar desires, similar struggles...

Well, that includes a sex drive. You lie down on your back and tell her to ride you.

She acts like she was waiting for it. She enjoys your hands anywhere you put them, but she focuses on your sex. She rubs her bare labia along the shaft for a minute and then slowly starts sliding it in.

While she's doing all the effort of riding your dick, you're free to notice something: These ladies are really clean. They have makeup but not a hint of sweat or anything else "dirty." She's sweating lightly now, but she seemed unnaturally clean when you first stripped her down. Her original model had been working all day.

Confusing. Is it about your ideals? About their identity?

...Wait a damn second...

You jam a finger in her ass. She seems as pleased by this as she did by anything else.

You pull out your finger and sniff it. It has a very faint smell, but not what you expected. It seems completely clean.

You ask the girl to switch holes and she doesn't hesitate. She goes very slowly, her pussy juice providing just enough lube but the process still being difficult.

She takes your cock in carefully but expertly. Despite her plain looks, the way she moves is one of the hottest things you have ever seen. The spread open half-fucked cunt pointing at your face really highlights her stretched asshole, and soon you are cumming again.
