With Obese Aunty

A story I read:

When I was in my early 30's I had a aunt on my mother's side who was morbidly obese, weighing close to 400 pounds. She was confined to a mobile wheelchair to get around, and I would stop by her place a few times a week to see if she needed help with anything around the house.
Whenever I was around, I would catch her in various stages of dress, and undress, and she never once made a big deal of it. In a lot of ways I was certain she was doing it intentionally, and I was so casual about it she rarely made any attempt to cover up.
One day while I was remodeling her patio she called me into her house. When I entered her home, I could hear she was in her bedroom, and as soon as I rounded the corner to her room she was sitting naked on her bed.
I could tell by the look in her eyes she knew exactly what she was doing, and when I asked her what she wanted, my aunt just leaned back in her bed with her legs open without saying a word. She had large tuft of hair covering her pussy, and I could see she was very wet from the sheen between her thighs.
We ended up having sex for hours that day, and when we were finished my aunt's pussy was a sloppy mess from the countless loads I emptied inside her. She was so happy to have had some intimacy with a man, she was like a different woman from that day forward.
Anytime I came over, when I wasn't doing something around the house for my aunt, I would fuck her brains out. Most times, my aunt wouldn't even clean up afterwards, and just roamed about her house half dressed with cum dripping from her until the next time we went at it.
My aunt may have been a heavy woman, but she gave me more sex than any woman I had ever been with. I had full access to her body, and when she or I wanted some sex, we had sex until I was completely drained.
