Matron Serra gasped as the digit invaded her ass, but she didn't resist.  Her tight asshole was firm and much harder to push into than a more relaxed woman.  But in very short order Doxi's finger was buried up to the second knuckle and the matron sighed,  "Of course captain."<br/><br/>The older woman then pressed a digit into Doxi's spit slicked anus.  Of course Doxi had a practied ease at taking things in her ass, so the matron quickly had her finger deep in Doxi.  Her mouth returned to Doxi's clit where she sucked the tight bud into her mouth and licked at it while sucking.  Her own hips were bucking back and forth lightly, begging for more sensation, begging for the release of orgasm.
