Well... Did she?

I feel like that's something you shouldn't have to check for your sister... FLY, OP. Especially if you're a guy.

Well... Did she?

They make OTC tests for that

This is why you shouldn't talk on speaker phone. Expect the unexpected.

I feel like this is a YDI if this is actually something that you would check for her but FML if she was trying to prank you while on the phone with your boss.

Um, can she not check something like that herself? Especially for something so intimate. It's really not that hard to see either, and you can generally feel something is wrong, they can hurt or itch. Sucks your boss heard, that's embarrassing, but it's probably pretty awkward for him to hear too. So I don't think he'd really want to bring any attention to it, and probably won't mention it.

It may not have stopped this but if you're on an important business call you should tell everyone in the house not to disturb you real quick.

You must be pretty close if you guys have that type of relationship.

Fun with siblings
