Bodyswap/script idea i think would sell well for you.
Basic premise is a 25 year old guy learned his girlfriend cheated on him and dumped him. He takes revenge by taking over her milf moms body and life. Initially doing it just as a quick payback. He realizes he likes being his ex girlfriends milf of a mom and masturbates and what's strange in his soul and mind starts to merge with hers so he regains her memories, ways of womanly speaking and after his first orgasm the two are one.
