Ultra-Fantastic Breasts

We were visiting my in-laws recently and I noticed her mom was not wearing a Brassiere, showing me her extremely large breasts (DD cup). This gave me a rather intense thrill. She noticed that I was excited; so she thrust her shoulders back, making girls even more pronounced. Whenever I'm pleasuring myself, which is often, I generally think of those ultra-fantastic breasts.
