Karen smiled appreciatively at Allan as he came up behind her.  She knew what he was going to do to her and squirmed a little in readiness.  The only cock she allowed in her ass was her husband's.  He was the  sole overlord and protector, keeper and ravager of her back passage.  And he was might good at remembering who he was going after when he mounted her.<br/><br/>She paused with her thick strap on buried deep inside her slave boy's stretched ass.  She waited for Allan to get comfortably inside her and took his stroke as a lead for her own rhythm into the younger man.  His grunts were blended between satisfaction, eagerness, and no small amount of pain.  Karen had chosen a strap-on that had a grip for her clitoris, so ever motion she made pushed the small button in delicious strokes.<br/><br/>"God, Allan...I love your cock in my ass as much as I do my mouth or pussy....." she gasped between thrusts.<br/><br/>She looked over at the pounding Sammy was taking and said to Josh,"I know what you're thinking Josh...and it's never going to happen....be glad you've got Sammy there to fuck like that.  I'll bet Allan won't mind if I let you lick my pussy though."<br/><br/>Josh grunted as he pumped into Sammy, "Ah...you know me too well, Karen.  I know the rules of the house though.  I'd be honored to lick that pussy of yours...as long as Allan says yes."<br/><br/>Karen lifted her head at Allan's tugging and groaned.  She closed her eyes and concentrated on the boy beneath her as Allan fucked her ass.  It wouldn't take long until she came at this rate.  As soon as Allan filled her ass with come, she'd squat over Sammy and make the girl lick her ass clean.  The thought of it took her over the edge...she groaned as she paused, shaft buried deep in the slave boy and giving Allan full leave to spend himself on her spasming body.
