In the first installment of 'The Babysitter's Reward,' our curious babysitter finds herself alone with the family's massive, throbbing secret. With no one to interrupt, she tentatively strokes her curious fingers along the shaft, feeling its immense heat. She tentatively wraps her lips around the head, marveling at its size, before eagerly taking more into her mouth. Her hand meets her lips, working the length as she moans, her pussy dripping with anticipation. She strokes faster, her breath hitching, until she can't hold back any longer. She gasps, her body convulsing as she climaxes, leaving her satisfied but hungry for more.
