They had to just stand there and watch. Their tits tied painfully to the rail above them, they wouldn’t have to be released once she was done, they could totter back to their cell just as they were. Tied by the ankles, if one of them fell the others usually did too. They couldn’t fall far of course, they would just dangle there, their weight completely on their bound breasts, screaming into the ball gags she made them wear.

But none of that was as bad as having to watch her, every day, cum three times, once for each of them. She rubbed it in their faces, moaning and writhing, telling them how good it felt, how stupid they were to have given theirs up. Sometimes she’d stand right up against them and suck on their swollen tits as she climaxed. She’d even give them little tastes of the vibrator, not enough to edge, just enough to remind them how good it felt.

Their release was simple enough, at the end of every cumming session she’d slide her cool fingers up between their legs and check them. If they weren’t wet they could go home, but if they were it was back off to their cell for another night stuffed with the toys she’d bring.

Two weeks in and they were all still dripping every time she checked. It was going to be a long stay.
