So this happened when I was about 18-19 years old. I was dating this chubby girl that had an equally if not bigger mom. I’m sure she would fit the BBW category.

Once in college I lived with my gf, her younger sister and her mom (the dad was out of the picture) one day I decided to stay home to catch-up on homework instead of going to my morning class. I decided to have a masturbation session before getting to work. Knowing I was alone in the house something just got me super horny and it was the idea of touching myself while sniffing my mother in laws dirty panties in her bed. So I decided I would.. the moment my nose got a whiff of her smell I was rock hard. I closed my eyes and started thinking of my mother in laws gorgeous fat body. Her had a huge ass and from her bra size i figured out she had 34 EE (just like my gf) I don’t know why but I felt like someone was watching me so I open my eyes and I see my mother in law in the doorway looking mesmerized by the show I was putting on. Before I could hide or say anything she whispered “Don’t stop”.. you could see the lust in her eyes .. so I kept stroking and I saw her hand was down her pants!

My mother in law was touching herself right in front of me !!! So I gathered all the courage I had and asked her to join me. She came close to bed and simply said “you don’t deserve me yet.. now cum”

So I did I came all over my torso she simply took a drop off my chest licked it and told me to leave her room and close the door.

She then proceeded to masturbate and made sure I heard all the noises.

Sadly that was all that happened as she found a boyfriend a week later.
