Ken is stuck at home alone and gets sick. Daisuke comes to take care of him. Lots and lots of sexual tension. Esp when Daisuke has to help Ken change or give him a sponge bath (or an actual bath) or hold him to keep his feverish body warm. Daisuke should be super aware of Ken's body and feel guilty/ashamed of being turned on while Ken is sick. If Ken makes a confession or gropes Daisuke while delirious, that's hot too. Middle/high school/canon age preferred.
