The cruelest thing I think I've ever done in passion? The question is far too vague. lol. I think the cruelest thing would be the time I told him not to cum in my mouth and he did. I backhanded him... then kissed him on the mouth, filling it with his own cum. Then calmly wiping my lips with my fingertips. And raising a brow at him before winking and walking out without a word.
Ecci, If you told him NOT to cum in your mouth, you had your right, and he deserve it. So therefore he has to learn his lesson, and I don't think you did a cruelest things to him.It was him that did it to you.
