That idea wasn't intended as a lemon. I was just commented that that was where my mind went first.
And in any case, you have a terrible imagination. It'd go something like this:
Character X takes Recette in. In order to not be a complete burden, Recette helps out around the house (for most characters, that is. If you go the Alouette route, I can totally see her making Recette a maid just to taunt her), possibly in a cute little apron or such. As time goes by, maybe months, maybe years, the person finds themselves having more and more tender feelings toward Recette... and not a few darker ones. Recette, acting the cute little wife once more, finally tempts them into acting, and finds herself being kissed quite thoroughly. From there, it would depend on the character as to how they would react to their own indiscretion. Shame, fear, worry... in any case, this being Recette, she's mostly just curious. She tells whoever it is that she's okay with it. Then starts sneaking more kisses. She liked it, so why not do it more? The temptation's worse now, and the character struggles with their desires, and of course eventually fails. They go further, and further, and further each time, until they reach a breaking point. At the risk of having Recette realize they've been taking advantage of her (juuuust short of actual sex, I'm thinking) they finally break down and give her The Talk.
As amusing as THAT conversation is, Recette eventually gets it. She understands. Then she asks if that's what they wanted to do with her, if that's why they keep doing... things... that feel good and then running away and pretending it didn't happen. Of course, the answer is yes. After a moment, Recette lifts up their hanging head, and kisses them gently on the lips.
Her answer... is up to whoever's writing it.
That's just a general sort of outline, a slow seduction of the innocent until the ignorance fades and innocence shows them a different path.
FINESSE. Most lemon authors lack it. Do not assume such of all of us.
