Silver-haired granny masturbates with dildo on couch

Stockings torn down to her ankles, the silver-haired granny peels her patterned dress up over her heavy tits and sinks the dildo between her legs with a slow, deliberate grind. Lying back on the couch with her ass lifted just enough to angle the toy right where it hurts, she bites her lip and works it deeper with each thrust. Switching to the bed, she stretches out on her back, knees pushed wide, and the dildo disappears between her thighs as her belly rises and falls with every stroke. Silver hair splayed across the pillow, she grips the sheets and moans low, her free hand kneading her own tits while the toy never misses a beat. How many times can she come before she finally collapses?
