Take her ass

You position yourself above Amina like a dog would. You tease her further by rubbing your cock against her pussy lips, dragging out another frustated moan from the genie. Her wet pussy further lubricating your cock before you pull away, Amina's eyes get wide as she feels your cock poking at her ass.

"M-master, what are you AAAAAAAAAAAAAAHHHHHHHH!" Amina gets out before you thrust in.

Now you can confirmed she's an anal virgin. Well, was now. Her hole is tight, crushing your cock like a vice, and you are only halfway in before her ass clenches.

The only sound in the room is Amina panting, either from pain or pleasure, you are unsure. While waiting for her ass to unclench, you move to toy with her breasts, figuring it would help. Your palms rub over her hardened nipples, electing a moan from the genie. Her ass slowly loosens up, and you take advantage by pushing in deeper.

"Oh gods..." Amina moans as she feels your cock going deeper. "Warn me next time you're going to do that..." She pants.

Taking that as a sign to continue, you keep pushing until you bottom out, your balls resting against her pussy lips.
