Fix It Wank

You're on a quick job fixing Monika's batheroom cupboard, but she's also in there finishing off getting ready to go out. You're able to see up her skirt and see her sheer red panties, and it's making your dick stiff. She then asks if you're able to quickly fix the shower as well, but she can see you're unsure. Monika can see you catching glimpses up her skirt, so if she was to tease you and allow you to wank your cock, will you agree to fix it?
