Talk to her.

“Hey Mrs.Smith” you can’t help but stare at the ample amount of cleavage on display and can feel your throbbing cock start awaken.

She gives a slight laugh and pats your cheek “I think I’m a little to much for you” she glances down and her eyes widen slightly at the growing bulge “Or perhaps not”
