Your sister enters

You hear the bathroom door swing open followed by a high pitched squeek, which causes the boyfriend to wake up.

Your sister runs into the bedroom, opens her mouth to ask what happened however stops once seeing the note.

She reads it in silence, her face getting progressively more pissed off, before she balls it up and throws it in the trash.

She wakes her boyfriend up fully with a slap across the face, before raising her foot over his crotch.

"You have one chance to save your balls, what do you have to say for yourself?" She asks, eerily calm though her face still proving her anger.

The boyfriend just stutters before replying "I-I don't know what happened! I just woke up here! You've gotta believe me babe!"
