Isaac had offered to carry the bulk of the stuff for the class barbecue, holding the bulky and considerably heavy box in both hands. He was soon pantsed, leaving him unable to pull his shorts up, lest he dropped the things, keeping him in exposed checkmate.
Yet he was entirely focused on holding said box, and had failed to even realize that his blue briefs were on display as he smiled and followed the others to their pit. The walk from the main reception to their area was quite a walk, and it had been an astoninshing ten minutes since his exposure. Still he was unaware, and his classmates had been thoroughly entertained, seeing his blue rear out for all to see.
No one dared to break the illusion, and Isaac simply felt confused by the smirks and snickers, wondering what the joke was.
