Spreader Bar Tease & Denial

Stuck in a spreader bar and teased. Not the kind of evening I had planned. He teases my juicy little pussy with his mouth, whilst gently fucking my hole with his thumb. I keep getting so close to climax, but every time I do he denies me. The more I grow frustrated, the more he delights in making me suffer. He removes his cock from his trousers, edging closer, rubbing it over my clit, skipping a motion to enter my pussy. He is now deeper inside me, my pussy gripping his meat. I think I'm going to... For fuck sake!
