[M4F] Manipulative kaamwaali

Looking for a very cunning kaamwali that works for a young guy in an apartment. She sees him do a 9-5 everyday while trying to juggle a bitchy girlfriend. She'd often find used condoms scattered over the floor on Monday mornings when she comes into work that indicates his high libido. On weekdays there was always the crusty underwear or sock for her to wash.
On a rare occasion, she heard a fight where the gf was pissed about something. A lot of English was thrown around but she did manage to catch her saying "Toh bula lo na koi randi GB road se apni gandgi ke lie" before she stormed out.
Is this situation something that she can exploit for financial gain? Is she going to seduce the guy or perhaps try some other strategy that leads to a new source of income?

Kinks: Spit, sweat, snot, pee. all bodily fluids welcome. This will be heavily focussed on messy stuff so please stay away if you are not into it. I am open to any kinks that you may have and would love to add them to my character.
