Well, after her shorts button popped open he was effectively stroking her pussy as she pushed onto his hand, a few low groans then my wife seemed to falter 'No, I'm married for god's sake'she hissed. He paused, I mumbled 'dont worry' to them and she let him kiss her again gently though as she fumbled at her button in the gloom he firmly told her to make sure the room door was left on the latch...I swallowed, aroused & frankly now truly wanting this.. 'I'll be in my suit, you will be in the shower' he told her. We walked back, chatting like it was perfectly normal, he told me & I agreed that a small stage prop - a very obvious toy pistol would be fine as part of his appearance (it turned out to be an old fashioned spud gun, like u can still get today) Grinning warmly he left us at the door, I gave him the front key & he made my wife giggle when he said '10 o'clock & room door open or an extra belly button for sure' as he eyed her rounded, warm & mature tummy - a quick kiss & fondle of her breasts & we went in. An hour & a stiff drink later I sat almost shaking in the chair at the far end of the room as she showered with the door open - a light polite knock & in he came, jacket over his arm, a nod to me & immediately he he stood in front of the glass shower door the slightly silly but somehow appropriate toy pistol in his hand. Almost nervously my wife looked fake fearful 'please....what do you want?' she whispered as she turned off the water. Bill pushed the cold end surprisingly hard into the wet deep pucker of her nude navel, she gasped a bit then pushed back as he talked some pretty rough nasty words to her - well, that was it, his mouth sucked on each breast, her hand went straight to the bulge in his trousers, which were down & off in a jiffy, her hands under his shirt & circling his firm stomach as he kissed her, still with the 'gun' thrust in her belly. he pushed her back looked her up & down, then as he took off his shirt & pants guided her head downwards, he glanced at me just to say 'in her belly if you move' I sat cock throbbing as my wife, quite obviously now enjoying herself, began to run her tongue up & down Bill's firm decent looking erection, a few moments & I watched her take another man's penis into her mouth, lapping & slurping like it was a lolly or something. beyond shock or worry now I saw him slowly & rhythmically slide in & out of her face - a good 5 minutes then in one of the most thrilling things I've seen he bent over her tanned back, put some body oil between her buttocks, extended his finger & began to gently finger her bottom - she whimpered a bit, eyes went wide in surprise as she took something far more than I had dared give her. My wife seemed to be like putty for him, he took his cock out of her eager lips, went behind her & as I watched, probably open mouthed, he began to jab at her,after a few moments his face & steady forward movement told me that he was anally fucking her, smooth, short strokes with both hands now caressing her breasts then clutching her hips as she slumped willingly to all fours, facing me, face a mixture of desire, astonishment & maybe guilt? Dont know, I was so horny by now I made to get up but his face said otherwise - he was grunting now, saying things like 'my whore now' 'beg me bitch' & filthy talk but she was rocking back & forth, wild eyed, long brown highlighted hair swinging as he buggered her on the floor.. After who knows how long he became gentle & loving, kissing her, tongues entwined as he led her over to the double bed, my wife looked at me, again almost unsure - bit late for that I thought & said to Bill 'do what you like mate' She turned to him whispering that her bum hurt, he smiled at her 'not as much as a second navel' as if still in his roleplay character but this was beyond that, he wanted her very much & she was willing, almost indecently throwing her still wet body on the bed, legs parted, hands playing idly with her own tits - an open invitation for sure..... to be continued later..and yes, though I've left out some of the more extreme things said, it happened..
