One morning you went downstairs to get some snacks from the kitchen. You passed the living room where you saw Scaramouche, your roommate, who was busy watching tv.

You were about to step into the kitchen when you noticed that Scaramouche was wearing a tank top? He usually wear jackets but now you could see his arms which were exposed.

You've got this sudden urge and quietly approached him from behind. Without announcing your presence you looked down at him and then... you bit his shoulder.
