After our fun at the sex shop we decided to chill out on Tuesday and visit a local stately home. On Wednesday we had a man coming to service our central heating, both Dave and Jack are thinking of changing their cars so they went off for the day car hunting. When the plumber arrived there were two of them. Rob the plumber, a good looking swarthy man, quite stocky and muscular in his young thirties. The lad with him, Jeff, a tall willowy lad in his late teens, quite fresh faced and looking younger. As we chatted over serving cups of tea, l asked Rob if he was busy, he said he usually was but this was his only job for the day. Me being the dirty slut l am a plan started to develop in my head. They had also met Fiona and later on l took her upstairs an explained my plan. I told her it was time for her to decide if she wanted to progress further, l told her the detail of what l had in mind. She thought for a moment then decided that she would carry it through and that she understood the "safe signal" system. I helped her prepare then went downstairs. It didn't take long for them to finish and as it was a hot day l offered them a cold drink in the lounge. Rob commented on the garden and l jokingly said how good it was for nude sunbathing, l could see his interest perk up. Then l asked them both how old they thought Fiona and l were. I could tell Jeff was a bit unsure of the situation but they both agreed that l was probably mid fifties and Fiona a couple of years older. When l told them that l was 67 and Fiona 73, Rob said we were in good shape for our age. I thanked them for their compliment then said that Fiona was convinced that no-one would find her sexy at 73. "What do you think Rob" l asked, " l reckon it all depends what she wears, what do you think ?" Rob agreed that it was easy to imagine her looking good in the right outfit. With that l called upstairs to Fiona, then as she entered the room asked the men if they thought she looked sexy in that outfit. Jeff sat open mouthed and Rob let out a "Fucking hell" as Fiona entered wearing her basque, pulled very tight at the waist, displaying her late tits and shaved pussy. She had her nipple clamps on with little weights attached elongating her nipples, l told her to turn around to show off the ponytail butt plug stuck up her arse. "Well Rob, would you fuck her, what about you Jeff ?" Jeff was struck dumb but Rob replied " You fucking bet l would, she looks fantastic" Fiona thanked him then l asked them both what they would like to do to her if they could live out their wildest fantasy. I asked Jeff first, he was very embarrassed but eventually managed to say "Blow job". I laughed and said he should watch more porn to give him some more ideas then asked Rob. "She looks like she could use a good spanking or even stronger" I said that that was more what l had in mind then walked over to a cupboard in the corner, opened it to display our collection of whips, belt and canes, turned to Rob and told him to choose. I then called Fiona over and put a ball gag into her mouth, buckling it in position, then told her to bend over the back of the armchair. I selected a thin whippy cane, holding it out to Jeff and asking if he wanted to go first. Uncertainly he rose, unable to disguise the growing tent in the front of his trousers, he took the cane and l told him where to stand and where to hit her. His first stroke was very weak and l told him he would have to make it harder, "Come on, l want to see some nice red lines on her arse". His next strokes got progressively harder until some faint red lines began to appear on her buttocks. Eventually Rob could wait no longer, taking the cane from Jeff saying he would show him how to do it. He had what looked like a good erection and as he started to let fire with some vicious swipes at Fiona's arse, l knelt at his side and undid his fly, releasing a lovely, thick, eight incher with a bright purple head. I told Fiona to stand and turn around, the tears of pleasure and pain streaking her face, then told Rob to give her some stripes on her tits. Again he was too gentle at first but with encouragement got harder as l slid my mouth over his cock, working hard on it as l could tell he was close. I could her the muffled yelps from Fiona as that cane swished down on her tits, the hits getting harder as Rob's cock swelled in my mouth then burst, pumping his cum into me. There was a torrent of it, l tried hard to swallow it all but the amount plus the size of his cock caused some to dribble down my chin. He dropped the cane as her held my head, forcing his cock into the back of my throat as his last jets of cum filled me. As l released him and stood up, l could see the magnificent sight of Fiona with bright red stripes on her arse and tits. I was proud of her, this was her first real punishment and she had not been tempted to give me the safe signal. Jeff meanwhile was just stood there totally awestruck at what he had witnessed, his cock now straining the front of his trousers. "Would you like to fuck her?" I asked, the only reply he could manage was a slight nod. "Which hole would you like, her cunt, her mouth or would you like to fuck her arse?" He looked totally confused, "l've never gone the whole way with a girl" he said. I went over to him, reaching for his fly and releasing his cock, it was even longer than Rob's but much thinner, now standing upright, the erection of youth reaching above his waist. "Well some lucky girl is going to love having that up her cunt" l said, taking hold of it and wanking it slowly. " l think for your first time you should stick to her cunt". I told him to lie down and let Fiona straddle him. Fiona was restraining herself well, she was obviously desperate for some cock and as he lay down she squatted over him, sinking down onto his cock. I told him it was better that way as Fiona would control the speed of the fuck which would make it better for him. He was in total paradise, especially as Fiona removed her nipple clamps and leaned forward to offer him her nipples to suck. I released her gag and she started encouraging him, telling him he had a beautiful cock, that she could feel him deep inside her. I noticed that Rob was hard again so l removed the butt plug from her arsehole and told him to fuck her there instead. He wasted no time getting into position, easily sliding deep into her gaping hole. Fiona was now moving back and for, fucking both cocks, l told Jeff to bite her nipples and tits while l knelt down and played with Rob's balls, tracing my fingers to his bumhole. Jeff had lasted well but could wait no longer and as l slid one finger into Rob's arse, he drove into her which forced her down onto Jeff and both men emptied their balls into her. Rob was soon spent but Jeff seemed to keep on cumming, Fiona had cum too and sank exhausted to the floor. As Jeff's cock slid from her cunt, still leaking cum and covered in a mixture of spunk and cunt juice l took him into my mouth to clean him off. It was at that moment that Dave and Jack arrived home, as the front door opened Rob and Jeff both made to get up in panic. I held firm with my mouth full of cock as Fiona told them not to worry as there would not be a problem. The situation must have excited Jeff as l felt his cock harden in my mouth as l sucked him hungrily. "I might have known you dirty cows would end up fucking them" Dave said as they entered the room. At the same time l felt Jeff's cock give a twitch and his back arched as he unloaded another load into my mouth. Dave and Jack were admiring the stripes on Fiona's arse and tits, Jack said it looked like she had been enjoying herself. She showed herself off proudly then as Dave noticed the lines of spunk leaking from both her holes he told Jack it was his time to show his commitment, he ordered Fiona to lie back on the sofa with her legs up high and open wide then told Jack to lick the spunk from both her holes. Full marks to Jack, he did not hesitate, falling to his knees and eagerly tonguing both holes. Dave asked Rob if they had enjoyed themselves, Rob said we were fantastic women, l finally released Jeff's cock from my mouth and said that they both now knew where l lived and they should get in touch anytime in the future they fancied a repeat performance. Both men then dressed and left having first kissed us both, Jeff was still gobsmacked and self conscious but l assured him that he was welcome anytime he wanted to try out an older woman. Even as they left, Jack was still busy exploring both of Fiona's orifices with his tongue. After us girls had cleaned up and put on dressing gowns, we all settled down to a light meal and some wine while we discussed what had happened. Fiona seemed proud of her stripes saying it had been painful but that she had cum when Rob started lashing her tits. I explained that both of us were almost at the same level and that the next step would be to arrange a trip to Belgium for both of us for further training from Peter. We then went on to plan our next evening as we were planning to go dogging. Thursday. We had a lazy day, l had spent the night with Jack and he had managed a couple of fucks and apparently Dave and Fiona had had a similar night. Around 6 p.m. we headed for the dogging site we had been given at the sex shop. It was a big lay-by on the A1. close to StNeots. When we arrived there were a number of trucks there mostly foreign, a group of men had arranged some chairs around a table on the grass verge and were enjoying a drink and chat. Fiona and l were both naked under our coats, we parked up and made our way over to them. Dave had brought some blankets and as we reached the men he said hello asking if they spoke English. It turned out they all did, then Dave asked them if they would like some entertainment. With that he produces a box full of condoms and put them on the table and told us to take off our coats. The drivers seemed hardly surprised as Dave and Jack arranged the blankets on the grass then told the drivers to help themselves, explaining the rules about condoms. There were five drivers in the original group and they quickly set about us. There was no finesse as each in turn slipped on a condom then buried their cocks up our cunts. Dave and Jack sat watching encouraging the men to be rough with us, saying that if any preferred it our arseholes were available as well. A couple more drivers came along, both British, asking if they could take a turn. Dave told them they were welcome, one of then only wanted his cock sucked, choosing Fiona's mouth to fuck. Dave told us later that that driver had told him he recognised me from a description his mate had given, apparently a chap who leaves comments on our posts on SH. It turns out they live close to us and Dave gave him our contact details for us to meet up sometime. Us girls were getting well fucked, each one taking his turn, some coming back for seconds. Dave said later that we had serviced nine drivers by the time they were all spent. Afterwards we sat round for a little while but slowly the drivers drifted back to their cabs to sleep off their evening. We were just packing up and returning to our car, both Fiona and l had our coats back on, when we heard a loud roar as a group of ten bikers pulled in to the lay-by. The group stopped around us, switching off their engines and a big fat one covered in tattoos said "Are you slags dogging" I could tell Dave was apprehensive but l felt the tingle of excitement as l opened my coat asking if they wanted some action. Fiona, to her credit, followed my lead, removing her coat as the group got off their bikes, surrounding us. Dave said he had condoms if they wanted to fuck us. The leader replied, "We're going to fuck them but we don't use those things" turning to us he said "get over there on the grass both of you, on all fours ready to take some proper cocks. Fiona and l complied leaving Dave and Jack by our car as we got on our knees. The bikers wasted no time filling our cunts and mouths with their cocks, the one fucking Fiona commented on the stripes on her arse saying that it looked like these old slags liked it rough. With that he gave Fiona some hard slaps to her arse as the one fucking me did the same. I had the leader's cock in my mouth and he was fucking me hard, ramming his cock into my throat as he slapped my face, calling me all sorts of dirty names. As each one came inside me they were replaced by the next and l saw Fiona was getting the same. She told me afterwards that she was having multiple orgasms, l know l was, and my reaction seemed to spur them on to treat us even rougher. Most of them must have had us twice, l think the leader had me three times, he certainly came in my mouth and cunt then fucked my arse but l'm not sure if he came then. My tits were covered in bite marks and they were red sore from being slapped, these fellas certainly knew how to treat a couple of old sluts. I don't know how long it lasted, it seemed to go too quickly but eventually they were all spent and us girls lay side by side exhausted. Then to finish off, they all stood round us and pissed on us, calling us dirty slags as they pissed onto our bodies and faces and into our open mouths. When they had finished they climbed back on their bikes, the leader went over to Dave saying they had known we would be there as he was friendly with the lad who worked in the sex shop. He said we were good sports and that they would like to repeat it sometime. We cleaned off as best we could using wet wipes then headed home. Jack was concerned that the evening had got a bit out of hand but Fiona and l reassured him that we had been fine and that we had thoroughly enjoyed the experience. Fiona and l shared a shower once we got home, making love to each other, bringing each other to orgasm with our fingers and mouths as the water cascaded over us. We all talked it over long into the night, wondering where this path was taking us but both us girls were sure we wanted to carry on until such time as we were finally too old to get any interest. We swapped partners again that night, Jack taking his time with me, telling me how exciting it had been watching us being so totally abused. He brought me to a slow and powerful orgasm and we slept on well into the next day. They had to return home on Friday, assuring us that they had had a wonderful week and that they looked forward to moving forward together. We told them we would contact Phil and Peter in Belgium and get back to them to arrange something. As we waved goodbye, l just turned to Dave and said "What's next?"
