You slid your face toward her glorious pussy. Right away you could smell that she had gone without showering again today - that was no surprise, she was always super horny when she went multiple days without bathing.
Looking into her beautiful pink hole you saw streaks and smears all around - obviously leftovers from your last orgasm together. How long ago was that - 3 days maybe?
You pushed your face into her, through the thick aroma of old sex and b.o., and dragged your tongue across her perfect hole. How did you ever find such a perfect girlfriend?!?
