Looking for hidden gem spicy books (preferably FF) to get me out of a reading slump!

I'm in a massive reading slump and I'm desperately looking for some spicy book recommendations!

A few things I'm looking for:

• Characters who are 40+ (I'd love to read about older protagonists for a change).
• No huge age gaps (small ones are totally fine).
• Bonus points if it's Femme x Femme / FF, but I'm open to MascxFemme too if it's really worth it.
• Plenty of spice, but I still want a good story and well-developed characters.

I've already read most of the really popular spicy books that always get recommended on BookTok and Reddit, so I'm hoping to find some hidden gems that deserve more attention.

What are your favorite underrated spicy reads? I'd love to hear your recommendations!
