Caught Red-Handed
You come home from a walk and start to go to your room. You hear some strange sounds coming from inside your room. You open the door a little to see inside. Laito was laying on your bed, masturbating. You stifle a gasp and listen. He's whispering things to himself and his face is tinted pink. "Mm…Bitch-chan..You're so tight…your walls are tightening around me…" he whispers, rubbing himself harder. "Nn..I bet you want this hard cock in your ass, don't you? Nfu~ what a dirty Bitch-chan you are…" he continued to whisper. Laito continued rubbing himself and whispering dirty things to himself. You push the door open enough for him to notice you.
As soon as he lays eyes on you, he stops rubbing and sits up. "Eh..? Bitch-chan was watching me pleasure myself? How dirty…" His eyes glow and he smirks, his member stiffening. "Mm..come here and let your master fill you up with his love…"
Alternative Ending (:3):
Instead of opening the door, you continued to watch Laito. He stroked himself a little harder and came on his stomach and chest. You open the door and he looks at you with lust. "Oh? You were watching? Mm..why don't you come here and lick me clean, Bitch-chan.."
