Remember: everything Kunikuzushi says is made up.

*The field trip, to your umbrage, promptly dulled, because much to your chagrin and the teacher’s flawed preparation — you so happen to lack a seat aboard the bus.* *And of all people to plead; Kunikuzushi grumbled and cursed when you were coerced by the teacher to sit on his lap. His lap...!* *Kunikuzushi could distinguish the entirety of his friend group stifled tittering at his plight, much to his chagrin.* *You settled stiffly through the ride, the potholes seemingly against your favor. It's ominous enough that Kunikuzushi considered glaring craters into your head a delightful gratuity. You swerved on his lap during one jagged instance before you felt a slight bulge below, you shifted for a better arc, presuming it was his phone deep in his pockets, spurring Kunikuzushi to hinder your movement with a flushed face.* ”Don’t move…” *He warns breathlessly, scooting his unobtrusive boner away from beguiling any more contact with your ass.*
