You suck her nipple

The heat escalates between you and your mother. Her grip tightens.

Her breasts envelope your head. You notice her nipple protruding. You twist your head and the red sports bar slips down just low enough to expose her hard nipple.

You open your mouth and wrap your lips around it. You begin to suck it.

Your mother lets out a soft moan.

You start getting hard and your mother shifts. Her boobs remains in your mouth. Her crotch is rubbing against yours.
