A tattoo

You're surprised when Sarah leads you to a tattoo parlor, which doesn't seem to be officially open at this still fairly early hour in the morning.

Walking in casually, Sarah greets a rather rough-looking woman who seems to be cut from the same cloth as Sarah, though at least a few years older.

The other woman, who you gather is called -at least colloquially - "Becca" from Sarah's greeting, pays no attention to you whatsoever, chatting casually with Sarah.

You get a little bored just standing there; they aren't saying anything interesting for the most part, but you can't imagine interrupting them would end well, so you have no real option but to wait. You do gradually pick up that Becca is - probably - Sarah's cousin though.

Eventually they run out of topics, and Becca gestures at you with a thumb. "So who's the pussy?"

You can't help but flush a little a that...you haven't said a word to her and she's already calling you a pussy...definitely related to Sarah.

As for her question, you're not sure how to answer that to the public. You doubt you qualify as a 'boyfriend', you're only a "co-worker" because Sarah is making you unofficially do most of her work for her and you don't know Sarah in any other settings...

Sarah apparently has no problems defining you relationship though. "He's my bitch."

Becca seems to take it as a joke at first, laughing out loud, but your embarrassed face and the lack of a second answer from Sarah seems to make her reconsider.

"Wow, you're serious?"

Sarah nods, giving you a malicious smirk. "Yup, came here to get him labelled." She steps over to you, lifts up your shirt, and puts a hand on your lower stomach, right above the pubes. "Whaddya think, can you fit Sarah's Bitch there?"

Your breath catches as her words sink in. She wants you to get an absolutely humiliating tattoo on a spot visible to anyone seeing you without your pants on...

It's not the kind of decision you'd normally want to make on such short notice, but Sarah's already put you on the spot. Refusing now means directly contradicting what she's telling you to do, and in front of her cousin at that.
