Damn tight, but Doxi fit it in all the way after a bit of effort.  She herself loosed a moan as a finger slid into her bunghole, and leading by example Doxi began to wiggle hers about, sliding out, and in a bit.  Pleasuring the backdoor, Doxi moaned as she sucked the clit and lips of the Matron, who in turn was sucking her own clit, and the bucking resulted in Doxi pulling out the stops, licking and sucking as the finger built up speed in her asshole, pleasuring every last inch of her loins with a practiced, furious passion.<br/><br/>Doxi's hips bucking, and the woman's tongue fucking, they'd see how long this lasted, and if - or what - the Matron would learn from it...
