Romantic/ecchi actions for nonromantic reasons

[BWTraveller]

Ok, I know several series that fit this but I was wondering if there's any I don't know. There's a number of shows in which characters want or need to perform romantic or more often ecchi actions for reasons that have little or nothing to do with actual physical or romantic attraction. Maybe it gives them some sort of power, or perhaps there's some sort of social/political reason. Whatever the case, the hero winds up doing or being pushed to do these things with many people.

Examples include HXH, where the hero can restore a girl's power and give her a substantial boost by pushing her well past the peak of ecstasy; as a result he pleasures girls in the midst of battle, and the girls sometimes try to get it on with him outside battle just to level up. Then there's Campione, in which the girls aren't really pursuing the hero for anything, but he is the best fighter they know to take on their enemies. The only problem is he needs to know everything about an enemy to use his power, and the only way to quickly convey this knowledge is through magic injected by Frenching. Also, it doesn't have to be an immediate benefit. One great example of this is Maburaho, a slightly older series in which a pathetically below-average guy in an above-average school finds out that he has an incredible lineage and therefore incredible genes. Since the girls at his school are pretty much all from prestigious families, and having an incredibly gifted child would bring far more prestige, every last one of them is willing to do just about anything to bear his child. This is looking further down the road than simply powering up, but the fact remains that the guy is surrounded by girls who have reasons to try and get it on with him that have nothing to do with their personal feelings.

Of course, this doesn't mean the partners don't have legitimate feelings for the character in question. The girls in HXH most certainly seem to be romantically interested in the hero. The girls in Campione are all very much in love with their "king". And in Maburaho, while the majority of the girls in the school just want him to impregnate them, the three main heroines have much deeper feelings toward the main character.

The lotion scene in episode two of Dance in the Vampire Bund probably qualifies. It's the most controversial scene in the show as I recall. Akira must cover Mina's body in a special sunscreen, and she appears only in panties. Despite being hundreds of years old, she looks like a young girl giving the whole scene an aura of pedophilia. Funimation censored this scene in its North American release.
