Yep, and she lets me choose where to put my cock.

"Well Matron, what do you think, are you up for another round?" "Yessss." She moans as she strokes my still hard cock. "And this time, you can choose where to put your cock." "Well, I've had your pussy and your mouth, so that just leaves one hole left." "B-But I've never had it in THAT hole before." "Well, you did say that I could have MY choice." As she hesitated, I got up slowly from the bed and went behind her, kissing the back and sides of her neck whilst at the same time, lowering her uniform. Breaking away from me she grabbed the curtain and pulled it shut. "If you want it, I have to do it, how do you want me?" She asked. "Bent over the bed please." As she bends over the bed, I move behind her and gently position my cock at the entrance to her ass. "Brace yourself Matron, here we GO!"

As I push more of my cock into her ass, the Matron starts groaning with pain and pleasure as I push deeper and deeper until I finally bottom out inside her. Building up a steady rhythm, I revel in the tightness of her ass. Eventually, I feel my balls begin to tighten as my climax nears.
