Please read how I first seduced and fucked my ex’s mother titled “Massaging my ex’s stuck up posh mother”. After fucking Belle we exchanged numbers before I left. I wasn’t sure if it was a one off but soon realised she wanted me as she messaged me thanking me soon after I had left. She offered to pay me £50 per week to come and massage her, I didn’t really fancy her but couldn’t stop thinking about our sex session and seducing and controlling her, and it was one of my best fucks. How could I not want a woman who would probably do anything I wanted sexually. I particularly loved dominating her, and the fact that she was posh, stuck up, married and my ex’s mother made it even more satisfying. I therefore agreed to her weekly massage offer. She was effectively paying me for sex. So the domination and weird relationship continued. I soon had her sending me naked pictures and videos of herself and ordering her to do tasks. She did as she was told and she loved being dominated and also got a massive kick out of doing her tasks. She only had a small vibrator and I made her go alone in seedy sex shops to buy herself vibrators and a big dildo. This was last summer and this was by far her best sex shop experience. In one she said the bloke working was a real perv and made her feel uncomfortable. She was sent in by me to buy the biggest dildo that she could fit in her pussy. I had made her tell the person serving her she wanted one that would completely fill her to satisfy her. She did as she was told even though the only one working was a really creepy guy. He showed her the ones on sale and she bought one, telling him that she wasn’t sure it would fit. She said he was creepy and suggested she could try it out in the changing room and even offered her lube and to give her a hand. When she declined he said they do not normally exchange but as she was lovely, he would let her exchange it for another if it was the wrong size. When she told me that she had politely declined his offer to try it for size in the shop, I told her off for not doing so. She had not done as she was told, and also had bought a conservative size dildo, and I knew she could fit a lot bigger up her. She knew she hadn’t pleased me and apologised and offered to go back and do whatever I asked, even though she didn’t like the guy there. And she did exactly as I asked. This time I went with her but went in before her pretending to be another customer and looked at stuff near to the cash desk. She followed soon after and within my hearing placed the dildo on the counter and told him she wanted an exchange for one bigger. She looked really sexy in a flimsy summer dress, I guess moreso as I knew she had no panties or bra on. Although you wouldn’t know she didn’t have panties on, it was clear she had no bra as her tits clearly wobbled around and her hard dark nipples were on display through the flimsy white material. He couldn’t stop looking at her tits. They then chatted as I browsed. Intrigued with their conversation I listened in. He really was creepy asking her if it was her husband that wasn’t happy with the dildo size. Knowing I was hearing she told him that her husband didn’t even know she had bought it, and then told him that she had bought one as her husband doesn’t satisfy her. His eyes lit up at that. I left and waited nearby. I noticed about 5 mins later that he locked up the shop and put up the closed sign. She informed me that when I left they got several dildo’s out and although she really didn’t like him, that she flirted with him and did exactly as I asked. She said she was really embarrassed but still told him that she had used a cucumber on herself once and loved the feeling of being completely filled. She chose a fairly big one and he again offered for her to try it for size. He also offered her a discount on it. This time she agreed to try it somewhere private and he showed her the makeshift changing room. She said he was clearly erect as she could see his bulge. She said she was nervous as hell and after getting some lube went into the changing room with the dildo and pulled the curtain. She said he looked gutted that he wasn’t going to get to watch. He asked her if she wanted help with it, and as agreed with me, she refused politely telling him that she was married. She did tell him that she may be noisy so could he let her know if anyone came in the shop. He told her he would shut the shop whilst she was trying it for size. As we had agreed she took her dress off completely, so she was naked behind the curtain. She had agreed to do all of this, as I was nearby and she had her phone with her, for safety. Once naked she sent me a naked selfie of her holding her dildo, as agreed, and a short text update. I told her to tease him and not shut the curtain completely, so she did as she was told leaving a small gap. She could tell he was trying to peek in and made sure he had little glimpses of her body. When taking off her dress she bent over with her bum against the gap and is certain he would have seen some of her bare bum. I was texting her telling her to show more. Naked she put some lube on the dildo and standing put one leg on the chair in the little room and slowly inserted the dildo in, again sending me a pic. I told her she was doing well and would be rewarded. I told her to moan and she she said she already was, as I know she can’t help herself. She told me that after a few seconds she thrust it in a few times and moaned a bit louder. The guy in the shop clearly heard her and asked her how it felt. She replied that it was teally good but she thinks she would like to try bigger. She took it out and the guy suggested she come and choose another one. She said she better not as she was naked and could he get her the next size up. This was part of the plan and she text saying that he was getting her a bigger one. I replied saying to fully flash him. She said on his return with a really big black dildo that she had half pulled back the curtain and that he would have seen her tits, but she had her hand covering her pussy. She took the black dildo off him. The crafty guy pretty much came in the changing room and asked her to pass back the smaller one, so she moved the hand covering her pussy to get it and pass it to him. Therefore he saw her completely naked. One of my previous tasks for her was to shave completely, so he saw her bald pussy. She closed the curtain again but left even more of a gap this time. The back dildo was massive and not the next size up. She told him that she doubts she could get it in her and he suggested she take her time and just try. She then said that she gave him a bit of a commentary as she tried to get it in. She couldn’t get it in, in her standing position so moved the chair, sat on the edge of it and put her legs up either side of a wall mirror. This also allowed her to watch herself. Well lubed she got it in, and told the shop keeper she had managed to take it. He suggested she take her time and enjoy it, so she did. She fucked herself with it and moaned loudly. He again offered to come in and assist her and she declined. She said she mainly had her eyes shut but when she partly opened them she could clearly see him through the mirror, peering through the edge of the curtain and he therefore would have had a clear view of her on the mirror fucking herself. She could tell he was wanking also though couldnt see his cock. Knowing he was watching she closed her eyes and fucked herself to a very loud orgasm. She said she kept telling him that it was so fucking big and that her cunt had never been so full. After orgasming she pulled the dildo out and opened her eyes and he was pretty much standing next to her watching and covering his cock. She called him a dirty pervert and asked him if he enjoyed the show. He nodded and apologised for looking, saying he couldn’t help himself. She told him to move his hands and he did revealing his hard average size cock. She was still sat legs apart naked on the chair but turned around. He then offered her the dildo for free if she sucked him off. This was not part of our plan and the dirty bitch offered to wank him for the dildo and he agreed. She then wanked him and after about 5 strokes he shot his load over her tits. After cleaning herself and dressing she left the proud owner of a free massive black dildo. Needless to say I punished my slut for wanking the guy off. For the journey home in the car she had to pull her dress up round her waist so was naked from the waist down with legs apart and couldn’t cover herself. Let me know if you want to hear more
