Basically, I'm looking for a romance where a younger man (at least two years) is in the dominant/leading roll in a relationship with an older woman. As always with me; nothing with rape, "open relationships" (anything that deviates from the ideals of monogamy in the physical sense, though love rivals are okay to an extent), or tragic endings. Smut is fine as long as it follows those rules.

I know it's a pretty specific request but... please help!

Game Over (Mizutani Fuka) one of the stories.

Maybe Nounai Poison Berry?

kono oneesan wa fiction desu!?
unbalance x 2 maybe

Thanks! Onee-san da wa Fiction doesn't exactly fit, but thank's for the suggestion; to make it a little more clear I guess "younger guy "keeping" older woman" would be another way to put it. The first few chapters at least of Cosplay Animal would work as an example, but there are moments where she's a bit to cool about their relationship to me (ie: when she fantasized wildly about one of her exes and then even went to his house.)
Again thank you, and please keep the suggestions coming!
