Cosmo Ejaculates Uncontrollably at Sight of Shit

Miss Kirsch and I have pinned Cosmo down firmly on the bed. Wearing our revealing lingerie, we first let him lick our assholes and take turns sitting on his face until he no longer knows up from down. Miss Kirsch's playful nature, in particular, drives him completely wild.
Then we put on our gloves. I sit on top of him and shove a huge sausage right into his mouth, while Miss Kirsch helps out and pushes it deeper into his mouth. I hold the vibrator against his cock and ask her if I should make him cum just by the sight of her asshole. He's already completely at his limit.
Pure ecstasy When Miss Kirsch then pushes her sausage out, Cosmo completely loses control. He stares spellbound as her hole opens, and comes violently to orgasm in that moment. He may have swallowed part of me, but just the sight of her shit has simply made him too horny.
