Back in '93 my cousin ended up going through a rough patch and left home, she came to live with us for a while and slept on the sofa until one night she came home drunk and stumbled into my room which was across the hall from the bathroom, before I could utter a word she was naked and kneeling over my face dropping her sopping wet cunt onto my mouth and nose, I could feel the heat from her thick thighs and taste her pussy juices as well as something else, I recognized the taste right away it was someones cum and it was dripping from her cunt, she rocked back and forth on my face until she came her thighs quivering and then she cralwed into bed beside me and cuddled.

This became a semi regular thing she'd turn up and lower herself onto my face and more often than not she'd have someone's cum inside of her, sometimes afterwards if she was interested she'd pull the blankets back and masturbate my cock until I came into her other hand or sometimes she'd let me cum on her large breasts but only if I licked off every drop and then she'd go to sleep. 

She shared my bed this way for most of the year until she got engaged, it turned out that she, her mum and my grandmother knew about my bisexuality/cross dressing training that my mum had been doing with me. Indeed her mum my aunt had once helped put on my make up even doing my lipstick and hair.
