Ogres stick to themselves mostly and don't bother humans. Therefore, the only way you'd ever end up in one's asscrack were if you were to sneak or slip inside yourself without her knowing.

That's probably for the best, as the atmosphere between her cheeks can only be described as lethal. Unbearably hot. Almost airless and so stuffy thanks to how fat her rump is. She sweats a lot and rarely washes. Her farts might be fatal to a creature as small as you as well, and the stench won't go anywhere fast. If it doesn't kill you, then it will break your mind. The previous demon lord had a captured hero who was too tough for even her most dangerous of magics. He was harmless, but she couldn't get rid of him. Max resistances. So she shrank him and shoved him up some village ogre's ass in her sleep without her knowing. Where ancient magics of the most powerful casters failed, the furnace like crack, poisonous sweat and fetid fumes of some NPC ogre succeeded.

Depends what ogres and what trolls. If it's an MGE ogre and troll then they are very different (I'd let an MGE ogre destroy me).
