Spongebath From Step Sisters Friend Leads To Threesome!

You're the best big brother I could have ever asked for.

So what's up? Mom said that you needed something from me?

Hey, yeah, um, well I'm kinda just stuck here and can't really do anything.

Mom left a bowl with some water and a sponge in it.

I'm starting to stink and I was just wondering if maybe you can give me a sponge bath?
