Fed my cum to my sis-in-law

After my successful experiment with my wife, I was keen to get my cum into my s*s-in-law.
She came over for a visit and while she was sitting around the pool with my wife, I ducked upstairs to organise some olives for them.
I drizzled about a third of my load over the olives and took them down to my wife and in-law. I offered them around and both took a cum covered olive and popped them into their mouths. So fucking hot watching my s*s-in-law munching on my cum! She ate quite a few, so she must like my cum :)

I'll give her some more next week, hopefully.
Any ideas for pool-side snacks that I can cum into for her?
Got some video/pics of the event if anyone wants to see them.

PS. Is it strange that I want to steal some of my s*s-in-law's underwear?
Becoming quite obsessed with her I think. :)
