Mine came when I was 10. I had a 14 year-old step-sister that could have made any well-known model run for her money. Truthfully, she used to beat the shit out of me just for spite and torment me like any normal sibling. I used to sleep in her bed with her quite a lot and one night turned out to be a life-changing event. She was lying on her stomach talking to me about how her dad drank too much and that school was stressful. She was in her panties and I asked her if I could look at her arse and she really didn't hesitate to pull them down. She told me to kiss her cheeks and shoved my head in her crack. She farted twice and the smell was like a mix of broccoli and brussels sprouts. I loved the smell, the sound and the feeling. I didn't sleep that night and I had space between my blanket, to say the least. I have been hooked ever since and the thought of that smell wakes me up like coffee. Only problem is, I can't tolerate this fetish unless the woman is attractive. There ya go...
