Her pussy cream dripping down m... chin, I stood up and slid my cock out of Esther's asshole. I shuddered at that last friction. Pleasure shot up my cock. Groaning, I stood up and looked around at all the horny girls.“You know,” I said, “I know we can't masturbate because that's a sin, but that's no reason you girls can't help each other out. “How?” Sandy asked.
