Hot Summer at Model's Retreat (Part 3)
You are panting and gasping at the end. It's really getting to be impossible to control yourself under her constant teasing. She smiles slyly at you and says:
"What's the matter, babe? You need some relief for that beautiful cock of yours?"
Of course, you do need relief, badly. All the time you've been here with her at Model's Retreat, you have been living with Sandy. She teases you constantly, and has daily 'practice' sessions where she makes you masturbate while she teases you. You are constantly feeling a deep ache and need for her, but your religious beliefs and principles, along with your mother's prohibitions, prevent you from 'spilling your seed'. So even though Sandy has you masturbate, and even sucks your cock, you never get to cum!
But you can't give in to her, and you shake your head: No.
You sit down, exhausted, and Sandy sits down too.
