The Hot Roommate

The bathroom door slams shut as Leon calls out to you from the hallway: "Hey, I forgot my towel – can you bring me one?" His voice sounds deep and a bit rougher than usual. When you stand in front of the bathroom, you see through the gap how he's soaping himself up under the hot water, the muscles in his back tensed. Steam rises, and for a moment you hesitate. Should you just go in? Or knock first? But then you hear his grin before you see it: "I don't bite..." he calls out, "...unless you want me to." The door is only ajar. What now? Do you go in – or wait until he asks you to?
