She sits on the picnic table, looking down on you as you kneel before her, and says:
"You know what to do: get yourself on the edge, and keep stroking so that you drip pre-cum on the ground!"
You are already hard, and it doesn't take long to get on the edge.
You feel very helpless and small as you look up at Emma, who smiles as she watches you struggle...
Soon the urge to cum is overwhelming, and you beg her to let you stop, please!
