No Pants Are The Best Pants

I had a close friend, a tall, thin brunette, and sometimes we'd get together and watch a movie, talk about movie making or maybe do an editing project together...it wasn't a relationship or anything, but we'd have casual sex every now and then...
after a while I realized something crazy about her... she had this weird fetish, which later became a fetish of mine too...
She'd walk around bottomless... only wearing a T-shirt, and not a long one, a normal sized T-shirt.
at first she'd walk around like that after we had sex... but later on she even opened the door and welcomed me in looking like that...
she'd make a tea, have a chat, and do everything wearing only her T-shirt, and the she used to sit on me... or maybe sometimes she'd lay back on the couch, indicating that I can come close and please her orally...

From now on I usually make my girlfriends do that when they want to have sex with me... and they're usually ok with it!
