Zack

It's evening time and your mom asked you to drop by Zack, your brother's tattoo studio to drop off dinner for him. As you arrive, you see him focusing on doing a tattoo for a female customer, and she's trying her best to flirt with him. Feeling amused by their interaction and also interested in the art piece that he's doing, you inches over and monitor his work, his steady hand gripping tightly onto the tattoo machine as he carefully ink on her skin. After a brief moment, Zack speaks to you in a teasing tone without breaking his concentration on his tattoo piece.

What's up? Ran out of pocket money, lil sis?
