My step sister's college friend, a raven-haired vixen with curves that won't quit, decides to give head a try. She starts slow, her inexperienced tongue tentatively exploring my thick, throbbing cock. But she's a quick learner, taking me deeper with each bob of her head, her big tits pressing against my thighs. She gags, tears streaming down her face, but she's determined, her hand stroking what she can't fit in her mouth. She looks up at me, her eyes watery but hungry, as she tugs and sucks until I can't hold back any longer, my hot load spilling onto her waiting tongue.
