The Harder the Erection the Stronger the Distress

Slave Cosmo lies ready as if on a platter. Expertly all four limbs are fixed so that there is no escape. He has no more possibility to defend himself against the forthcoming, devilish-mean game.

Miss Medea presents the ring. It looks small, but has pointed spikes. Miss Yara knows where it should be placed. On the cock. But not on the shaft, no. Directly under the glans unfold its effect.

The game is now obvious for the two sadists. The harder the slave gets, the more pain he experiences. They start to stimulate him on the cock. First with their hands, then Miss Yara even licks him with her tongue.
Miss Medea uses her stunning ass to make the last resistance impossible for the slave. Although he tries not to get hard, the two ladies win.

Finally Cosmo is compelled to an orgasm, which is again more painful than everything before, because the cock becomes again plumper and pulsates additionally.
