Mistress had a few friends over yesterday. When I came home four of her friends where drinking wine and laughing. On the dining table was an iPhone with a stopwatch app active and my chastity cage keys…
Mistress told me they wanted to play a game. I was to get naked and unlock my chastity cage.
Then they would start the stopwatch. I was to jerk off as they commanded with “faster”, “slower” and “slap your balls”.
They had a bet going on how many minutes I could last before cumming.
To encourage me to last as long as possible, the winner of the bet would give me twenty kicks in the balls, minus the number of minutes I’d lasted.
