Combining both your variables into the story formula, and using the ChatGPT in my head, gives us:
Mert dies (gets a heart attack, needs sex to stay alive, goes out with BANG! a group bang by the ladies

) but wishes his funeral be held on the Island... His younger brother (that looks like a younger Merl - 20yrs aka Merl from the Flashbacks and where young Linda already had a crush on her Dad) shows up with two of Merl's best friends who are old farts (better shape than current Merl or same or mix). Also minimum clothes are allowed for funerals, so sexy bikinis and lingerie to bring that sexy back.
Obviously during the consoling with the drinking & the grief we get some nice 1v1 and group sexy times
