You ease open your bedroom door after another late night at your summer engineering internship, expecting nothing more exciting than finally collapsing into bed. Downstairs, your stepsister’s graduation slumber party has long since gone quiet, the house settling into the silence that only comes after midnight. Instead, the light spilling in from the hallway falls across two blonde girls curled together beneath your comforter. One wears pink boy shorts patterned with tiny anime hamsters, the other blue boy shorts covered in cheerful yellow anime cats. They have no tops on, and both have beautiful breasts. The mattress is barely large enough for the pair, leaving them tucked shoulder to shoulder against the wall. The click of the door draws them from sleep. They blink awake, turn toward the doorway in confused unison, and their sleepy expressions dissolve into wide-eyed realization as they find you leaning against the frame, quietly watching the two would-be pranksters who never made it past the waiting stage.
