Spy Training

Spy Training by cactusman

You start stroking while she watches. She smiles as you struggle to hold back the sperm that are gathering in your straining cock...

She smiles and says:

"That's good, but I want to see more pre-cum! Can you make the pre-cum drip from your cock all the time while you stroke it?"

You don't think you can take any more, but the way she is commanding you is a fantasy come true. You try very hard to obey her, even though the more you try, the more difficult it becomes to hold back!
