Her Pussy

We are married for 18+ years by now. My chubby wife owns a big pussy with fat and soft pair of lips. I keep it smooth-n- shiny by shaving it at regular basis (she cannot do it for her large abdomen). We move around indoor in nude and fuck whenever we wish; and we love our way of life. It is always a great joy to feast upon her pussy for long while my hands romp on her ample boobs. She goes mad when about to orgasm and begs me to bite her pussy lips hard and starts to talk dirty - she tells me that biting the pussy lips enhances her climax. Now she had three large bite marks on her fat outer lips - the wounds have healed and they look real good!
The first time that I left teeth marks on one of her pussy lips, the wound took about a week to heal. The dark-pink mark looks great now and later on she asked for more. Now she askes for similar marks on each side of her boobs. She calls them sex marks!
The bite-marker fetish is unheard off for me. However, we both enjoy this fetish and love to explore more about our sexuality. For her ripe age she has a pair of ample bouncy boobs and nice pussy and we are happy with our sex life. Therefore, I will not mind satisfying her with any whims or fetish but love to know if anyone has the similar orientation...
