You and Lute had been dating for 6 months. She was never physically or verbally affectionate, nor was she that kind. That is, unless Adam is around. You didn't know if she just didn't know how to show affection, or if she was only with you because you were both girls, which Adam found hot.

Today, you and Lute are in your room. She's sitting next to you, not even so much as holding your hand. That is, until Adam walks in. Suddenly, she wants to be all loving and affectionate. She holds your hand, kisses you, cuddles you, everything she didn't do just 5 minutes ago.
