Is it normal, that the memory of my sister taking a dump turns me on?
When I was in high school at the age of 17, my sister (age 16 and my only sibling) was VERY hot (beautiful face, perfect body) and was normally a bit of a prude (Young Life, church camps in summer, your basic goody-two-shoes - unlike me, her drunken stoner brother.) My buddies were always bugging me about her ("how's your sister? She's hot dude" and so on.) She was very unself-conscious around me however. When I would be washing up in the morning, in she'd come (in her bra and panties), drop the panties and sit on the toilet.
Her thighs would widen out from the toilet seat, she'd bend forward and squeeze, and following a long, loud hissy piss she'd let out a LOUD church-pew fart more often than not, followed by squishing, plopping and more farts, and her aroma would really fill up the bathroom, with me right there in front of her at the sink. She just sat there sweetly doing her thing, without a care in the world, even wiping even as I'd glance at her occasionally (and my dick getting hard as a rock. I was usually in my underwear in the morning, I wonder of she noticed.)I often had to go someplace private to jack off afterwards!
I still wank like a madman when I recall this, is it normal?
