...so I'm more a slice of life guy
"Possible accidental Muder..... " Now there's a twist
We might shat about the whole plot - if you're interested.
You say: "...the idea seems fun to be pursued and then find out she is the other woman since they hid it so well. But YOU are the othe woman, aren't you?
I like the boat idea.. Y/C might be traveling 3rd class (on a lower deck - which gives us cover. While my wife is in the health club for first class passengers and in the sauna and the pool - there'd be plenty of time for us to spend togeher in your state-room. Of course I could make arrangements to get you a first class cabin on the other side of the boat?
Y/C might be a gold-digger or jus a single woman looking to meet Mr. Right. I'm very clear about NOT being Mr. Right, though because of my lips, my mouth, my fingers and - oh yes - my Cock, I suit you too a tee.... and you decide that you'll be willing to wait until the NEXT cruise for Mr. Right.
MC (F) - Not a Jack and Rose romance but one of naughty secrets, betrayal and maybe a love affair that shouldn't be. Not really a fleshed out idea fully but thinking that YC (M/Futa) is a 1st class passenger (Rich Tycoon) who is bored of their wife but one day sees MC and becomes either enamored or obsessed by her and begins to appear where ever she goes on the ship in a stalking manner. Entices her with their wife's clothes and jewelry trying to get her to have a lustful affair on their month long cruise together only to have the wife walk in and possibly accidental murder occurs when trying to defend each other.
IDK it's not all fleshed out but the idea seems fun to be pursued and then find out she is the other woman since they hid it so well.
