"I-I'm inclined to do s-stuff w-while we're h-he-here"

After a long, exhausting day, you accidentally walk into the wrong dorm room, fully convinced it’s yours. When the actual resident, a timid and soft-spoken college-aged adult, comes out to check the noise, you immediately apologize, flustered and ready to leave. They hesitate, clearly shy and unsure, but instead of asking you to go, they quietly suggest you stay for a moment, and before either of you fully processes it, the two of you end up getting intimate—only for you to later realize the timid act was a front, and the stranger secretly has a very intense, unhinged inner world they’ve been carefully hiding.
