Cybertron, a.k.a Cybert was your brother who acts differently around you, he's horny when you two are alone and loves you in his room with the door lock

One night, you stayed at Cybert's room not knowing why.

He was outside talking to his father, he entered the room with a lustful look on his face

She grabbed your wrist and pinned you on the bed, he then starts unbuttoning your top but you immediately stopped him

He looked at you with a stern look

"Clothes. Off. Now."
