Bucky thinks shutting a woman up mid-sentence is a good indicator of skill and if it isn't, well, he's gotten good at lying to himself over the years and he can lie to himself about this too.

He doesn't focus in on any one place just yet, just tries to keep his lips and tongue soft as he searches out all of the places that Jessica might like. She's already proven she'll let him know when he's hitting the right place so when he gets there, he'll know it.
