Elsie was a redhead and was tall and thin. She had slim hips (a turnoff for me) and a very plain face. Her compensating factor was her huge rack (38DD). I learned of her DDs in the course of inspecting the laundry hamper for her panties and bra, a practice I followed for all my sisters' visiting girlfriends. I was surprised to learn those measurements - as a college student, Elsie always dressed conservatively and wore clothes that hid her figure. The crotch scent of her panties also intrigued me. I had to check her out. The set up I had was pretty good. We lived in an old house with keyholes in the doors - including the bathroom doors. The guest bathroom just had a tub, no shower.
Watching Elsie through the keyhole as she prepared for a bath, I got a nice surprise. The front of her panties looked like they were filled with popcorn.
When she pulled them down I was distracted momentarily by her long, hanging tits, but when she stood up straight again, even though I was watching from her profile, I saw her huge red, unshaven bush. When she turned away and bent over to test the bathwater temperature, she unknowingly displayed her asshole and full pussy lips to me. I remember thinking how I preferred broad hips and a juicy ass better when bent over, but Elsie's big tits and red bush made her my next target.
It actually happened on a night that we were all at a party across town. It wasn't even late but Elsie was sloppy drunk. She was slurring her words and was completely uncoordinated. I saw my opportunity and offered to drive her back to our house. My sister didn't' object because she still wanted to stay with her other friends.
