My girl's pain

I love my girl. We fit together so well both mentally and physically. Our Dom/sub relationship is really amazing to me at times. While both of us love the power exchange of our relationship and I do love administering punishments and funishments to her, she is a true masochist. When we are having sexy times the way that pain can turn her on blows my mind, She can orgasm from a spanking with a leather belt, hard pulling of her hair immediately makes her wet (I like to think it's the kisses that I give her as I am pulling but I'm just fooling myself). While pain and submission are the basis of our sexual relations, she surprises when her masochism reaches in to the non-sexual part of our relationship, the other night we had a disagreement about something and when we had come to an understanding about it at the end she calmly asked if I would bite her back. I do this to her quite a bit during sexy times but for her it eased her mind after the disagreement. Her reason was that it clears her mind. I gave her quite a bite and am including a picture ...Have a great one
