Honeybees in Japan have only one defense against the huge-as-fuck Japanese Hornets - they use sheer numbers to swarm around the hornet en-masse, and they vibrate their flight muscles. This raises the temperature inside the mass to 47C, and Japanese hornets can only tolerate 46C. A few honeybees die for the cause, but stopping a scouting hornet from reporting back will save the entire hive.

Translate this to hundreds of honeybee-tans swarming the Japanese Hornet protagonist in an attempt to save their hive. Maybe throw in the caveat that they have sex with him in their attempt to "overheat" him, and you can turn this into an eroge.

Their plan fails (somehow?) and the hornet decides he cannot help the nest be destroyed by going back, so he lives with the hive as their protector. Cue several routes featuring various worker bees, the queen, and of course a pupae route for the loli inclined.
