Hot Power Couple at our Daughter's School

Our daughter started 1st grade in a new school in Brooklyn a few months ago.

There is this particular couple whose kid is getting along very well with our kid, and they are pretty cool and very attractive. We've heard from other parents that they are a power couple here in NY, he is a talented architect and she is a fashion designer.

Is it weird that I'm having sexual fantasies with them? Is it weird that last week I decided to act on those feelings and somehow got myself an invitation to their place?
