I wanked him for a good five minutes in that alcove, all the while his mates kept watch and did not intefere.
He was getting excited, and realized a little late in the handjob that I was trying to make him go.
"Wait. Maybe we shoud stop," he said.
"Sorry, no virgins for you tonight, love. Only the hand of a RIGHT SLUT!"
It was that moment that he realized that he was trapped.
But he was pinned there by the weakness that only lust can bring.
And I loved it.
