When the cock was completely turgid, she slid onto her knees in a straddle of his body.  It had been quite some time since she'd had someone inside of her, and she knew she was going to be insanely tight.  When the bulging head pressed past her slick pussy lips, she groaned.  Half pain, half pleasure, and half mortification at knowing Tony was watching, she pushed her hips down until she'd rocked the bound man all the way into her body.<br/><br/>He looked tormented by the pleasure her sweet body was causing him, and she watched him tremble with a mixture of morbid fascination and wonder.  She undulated slowly, feeling the thick cock rubbing along her walls.  It wouldn't make her cum, but it felt good.<br/><br/>Kat moaned because Tony wanted entertainment.  She arched her back.  She palmed her own breasts and pinched her nipples.  She gave him a show.  The sight of the cock disappearing again and again into her was lewd and erotic, stretching her and filling her.  Entertain she could do.  Enjoy it?  Not really.<br/><br/>She did as she was told.  The slave was being obedient.
