I'm not sure about specific 'natsu and futa lucy lemon fanfiction' off the top of my head. You could try searching on popular fanfiction websites like FanFiction.net or Archive of Our Own. They usually have a wide variety of fanfictions based on different themes and characters.
One common theme is adventure. Since they are from the Fairy Tail guild which is all about going on quests, many fanfictions continue this trend. They go on new adventures together, facing powerful enemies and discovering new magic.
The theme of unrequited love can also be common in some 'lucy loves natsu fanfiction'. Maybe at the start, Natsu doesn't realize Lucy's feelings or is too focused on other things like his next adventure or his training. This creates a lot of tension and drama in the story, as Lucy tries to hide or express her feelings while Natsu is oblivious.
One common theme is romance. Since Natsu and Lucy have a great chemistry in the original series, in hotel fanfictions, the hotel setting often provides a more intimate and private space for their relationship to develop, like in 'A Romantic Hotel Retreat' where they finally confess their feelings in a cozy hotel room.
One common theme is the exploration of their unspoken feelings. Often, in the series, their relationship is somewhat ambiguous, and fanfiction allows for that to be explored more deeply with the kiss as a climax of those pent - up emotions.
Often, adventure is a common theme. Since 'Fairy Tail' is about a guild of wizards going on quests, in 'fairy tail futa lucy fanfiction', Lucy might embark on even more dangerous and exciting adventures. And power exploration can also be a theme. The 'futa' element might be tied to some new power or ability that Lucy has to discover and master.
Well, family is a big theme. Since Lucy is pregnant with Natsu's child, it's about them starting their own family within the Fairy Tail family. Love and protection are also common. Natsu would likely be very protective of Lucy and the unborn child, showing a deeper side of his love. And sometimes, there's the theme of sacrifice, like Lucy might have to sacrifice some of her adventures for the sake of the baby and Natsu might have to change his carefree ways to be more responsible.
