'Goodness Charlie you have got yourself all excited haven't you?' said my wife in her nursey voice,and then i heard him groaning in pure pleasure as Doreen wanked his cock 'My My that's quite a big one you have isn't it you naughty boy?'she continued on. Doreen put a condom onto Charlies erection and i heard him say 'Will you suck it for me Doreen?' By the sound of the ecstatic groans he made i knew that my wifes hot mouth was pleasuring his 'suprisingly' big penis.By now i was furiously wanking my cock whilst trying not to make to much noise as i imagined my lovely wifes head bobbing up and down on his swollen organ.'i want to put it in you' he said,i didn't expect Doreen to go this far but i learned afterwards that she had been very excited and got carried away,'Let me take off your knickers Doreen..That's a good girl..now lie back'.Soon it was Doreens groans i heard along with the gentle rocking of the bed,'Ooooh that's nice Charlie,it fills me right up..Oooh yesss'. Charlie continued fucking my wife,very slowly (at 76 i'm suprised he managed at all) but the sensations where pleasurable enough for my turned on wife who praised his thickness as he enjoyed her tight cunt.
