Chess was enjoying this, having already cum once to it... but apparently the wo/man couldn't keep up the pace... least not for more than five minutes (then again, how many could?  Not everybody was chess after all).  She didn't want hir to overexert, so moving her legs, wrapping them around hir waist, and pulling hir in up to the hilt, every inch inside her ass, she sat up and gave hir a kiss on the cheek.<br/><br/>"Mmm... you look tired... let's shift things a bit." Chess suggested in a sensual purr, and with careful maneuvering would slowly rotate them about, so that s/he was back on her back, and Chess was back on top.<br/><br/>Thank the gods she was flexible, and after a bit of shifting she was soon impaling her own ass on the wo/man's stiff dick.  She ran her hands up and down the flat chest of the elf beneath her, looking down at hir with lust in her eyes, tweaking hir nipples and playing with hir chest (she wished there were tits there, but she could live without them this once, at least) in general.  She rode the wo/man hard and fast, knowing her as could take<em>far</em>more abuse than she was giving it right now, and began to do everything she could, every trick she knew, to make this a most enjoyable experience for the wo/man.<br/><br/>"You love your mistress' ass, don't you?" she purred as she rode and tweaked hir "Let's see how much you can take in the next ten minutes... though I'll be<em>so</em>disappointed if you don't cum in my ass soon..."
