"The younger woman tried to suppress her excitement. What perfect timing! "Here, you take these, and I'll carry your bag. The elevator is busted again... after all."Mrs. Robinson laughed, and handed over the impressively large bag of groceries she had been carrying. She took back her keys and the small parcel. "That's sweet of you honey. My arms are a bit sore after my workout."The spry old woman led the way up the stairs. Amber actually had to struggle to keep up. "Slow down Mrs. R! It can't be. I slid the vibrator in with one push, I was so wet and ready. I slowly fucked myself deep and hard until I felt the start of my orgasm.

Her fingers couldn't even fully encircle my width. How cute. If this was her hand I couldn't even imagine how tight her pussy must be. She stroked it and stared for a while, not sure what to do.
