Sorry for the delay holiday Xmas etc. As I left it in part 4 I was naked in Bob's flat restrained by my balls to the radiator pipe blindfolded. I could hear them snogging and the rustling of clothes, he whispered to her then she giggled and came over put her arm round me "we think you want to know what gets me so excited so kneel down, as your restrained your going to have to measure it with your mouth". "open wide" lol then i felt Bob's big bell end forcing its way into my mouth, she put her hand on he back of my head and pushed it forward as Bob pushed his hips forward. My mouth was full I was struggling to breath the gag reflex started, they released me Mandy was roaring with laughter " you have had a man size cock in your mouth and your little stiffy is harder than when you try to make love to me". "stick out your tongue" it touched Bob just under his bell end and Mandy told me to "lick down to his balls so you can feel the length. I felt like I was licking for ages then i encountered his big bollocks, "kiss them darling and tell Bob what he should do with them". I told Bob "I wanted him to empty his balls into Mandy so I could lick his cum out of her" They were both laughing as they moved away. I knelt there for what felt like an hour listening to Mandy begging him to fuck any way he wanted anytime he wanted, and them slapping against each other, Mandy screamed out her orgasm twice before Bob grunted that he was "flooding her married cunt". I could tell they were hugging as Mandy said "you certainly know how to satisfy a married woman" There were more kisses Then Bob said "shall we see if the pervert wants his treat", Mandy " Jim do you want some sticky fanny pudding ?" "yes dear" "well we have a problem unfortunately I have creamed all over Bobs big penis so you will have to clean him first". He came over held my head and forced his cock in my mouth telling Mandy to "keep her knees up to her tits to keep the spunk in", he made me suck the helmet then lick every inch of the shaft then his bollocks, 10 mins I was licking for before he pulled out then slapped my face with his cock. Then there was a scraping as he dragged the coffee table in front of me obviously Mandy was laid on the table. I then felt Bob's hand on the back of my head he pressed my face into Mandy's soaking gaping hairy cunt. Whilst I lapped away they chatted Bob asked " when was the last time he came" Mandy "he wanked his little cock raw on Tuesday and probably pulled it at work today". " Shall we put a stop to that". Mandy "mmmmmm!". Bob went and got some drinks I was stood up by the wall I was still stiff Bob held my hips against the wall then Mandy held a glass of iced water up to my balls, it soon had the desired effect I wilted then she force my willy into the water. I was kept like that for 10 mins then Bob said "Get his present Mandy", she came back "whats a cb 6000", Bob "a device to stop perverts wanking" Mandy "oh its extra small should fit perfectly". When it was fitted they went to the settee and fucked again, while fucking Bob told Mandy he wanted to keep it to Tuesdays and Thursdays so when they parted he would say C U Next Tuesday or Thursday as she was his cunt. When I had finished cleaning them up after their second fuck Mandy went to dress Bob Told me not to worry as "I would have a sex life on Thursdays but he would have Mandy on his own on Tuesdays.I took her home where we slept like the dead.It was a real struggle getting up Friday and boy did the morning glory hurt. Mandy told me on Friday night that Diane insisted on all the filthy details at work and lots of colleagues were looking at them as she screeched O.M.G at each revelation. tbc
