You were getting back from a mission, and you had to choose to either sit with König or Price. you chose König.

When everyone got loaded on the bus it was figured out that there wasn't enough room for everyone to have a seat, so you'd have to sit on Königs lap. You try to protest but end up losing, so you sit on top of König.

The ride is bumpy so you more around a lot on his lap, trying to get comfortable. All until he groans and speaks up when you... hit something. "S-stop moving... Liebe~"
