It's interesting that part 2- where Sue received her first hard spanking - wasn't so popular. As time has progressed, it has become less common for us as well. Sue still occasionally loves a good, hard spanking, but our tastes have progressed in other directions. We learned that a skillfully applied, but less severe spanking produced at least as good results, without any subsequent bruising, and that remains a regular activity. We bought some sexy outfits and toys online, and Sue loved to dress up and use them. We'd taken some photos after her spanking, and the camera was now always close to hand to record whatever she wore or did. She would often send me photos whilst I was away - usually with a toy in her cunt. As well as becoming much more sexually liberated, Sue's sub side was also becoming more apparent. As we recovered from one session - where I'd fingered her to at least 3 clit orgasms, Sue said, I loved that, but if you ever want to just fuck me, you can. A few days later, I tested her offer - she was in the kitchen emptying the dishwasher. I pulled down her shorts - nothing underneath of course - I kept her bent over and shoved my dick into her cunt. It only took two or three thrust before I was all the way in, and then I just fucked her - holding onto her hips, pounding away hard and fast. Sue was almost growling, and saying "yes" and "fuck" as I had my way with her. I couldn't last very long, and realising I was going to cum, I gave her a few extra hard thrusts before emptying my balls deep inside her. I gave her a few more strokes before withdrawing and wiping my dick on her shorts before pulling them back up. I told Sue I was going out to the shops and she couldn't take her shorts off until I returned. I was deliberately slow, and it was nearly two hours before I got home - Sue met me at the door and gave me a huge snog - her tongue tryng to force it's way down my throat. That was fucking awesome, she said when we finally broke for air - you can do that anytime you want. I shoved my hand down the front of her shorts and her cunt was soaking with a combination of our juices. A few strokes on her clit and her knees were buckling again.. Without telling Sue, I made some further on-line purchases. I'd also timed the order, so that the parcel would arrive on a Friday, when Sue was working, but I would be home. After dinner, I told Sue to go up to our bedroom, put on hold-ups and her boots (another on-line purchase) and to stand facing the corner with her hands against the wall. I'd done this a couple of times previously, following-up with stroking her body with a feather, but throwing-in a few spanks as well. It drove Sue crazy, and she was excitedly expecting more of the same. I waited for 10 minutes, knowing that the anticipation would magnify her excitement. I entered the bedroom and immediately put a sleeping mask over her eyes to blindfold her. I'd also done this before so Sue was expecting it. She certainly wasn't expecting to feel me tie a rope around her waist. One at a time, I pulled her arms down and tied those to the rope, so she was stood blindfolded, with her arms tied to her side. I put a towel on the bed before laying her on it on her back. I then tied her ankles to her wrists so she was stuck, helpless, with her legs bent and spread. For some time, I'd been fascinated by squirting. I'd read on-line about the "beckoning" finger motion that was supposed to result in a squirt, and I'd tried it on Sue a number of times before her change, without success. I hadn't told her what I was doing - which was probably at least partly why it failed. But if I had told her she would have stopped me. I tried to get her very turned on before using the finger technique, but she would stop me, saying it was too sensitive. I was now going to try again, and this time she wouldn't be able to stop me. I started off with the feather, paying particular attention to her tits and nipples, that were now rock hard. I also used it on the inside of her thighs, but avoided her cunt - partly because the feather would have got wet, but also to increase her desperation. I also tilted her on her side to stroke and gently spank her bum. Turning her onto her back again, I finally started working on her cunt with my fingers. Gently stroking her lips, around her hole, and her clit. I could tell she was getting nearer to orgasm, so I put my middle two fingers inside her cunt and started the beckoning motion. Her cunt was soaking, and the front wall felt spongy - almost squishy. She seemed to be enjoying it before shouting no, stop,stop. Sue told afterwards that she thought she was going to wee. I ignored her protests and continued the motion, pulling up into her cunt wall, Suddenly, she almost screamed "oh god" and as I pulled, a slightly opaque liquid started fountaining out of her cunt. I kept going for maybe 30 seconds, as the liquid kept flowing, before finally removing my fingers. The towel was a waste of time, some liquid missed the towel, and we discovered afterwards, that the bed beneath the towel was drenched. Sue seemed to be almost unconscious, and I quickly removed the blindfold, and untied her. Her eyes remained closed for a minute or two, before she opened them and smiled. What the fuck was that? That was the best ever,it was nothing like I've had before. I gave her a brief explanation and next morning we tried again. This time there was no resistance, but I only let the squirt last a few seconds. I'd read that squirting orgasms were repeatable, building on each other, and I wanted to test the theory. I stopped after reaching double figures, just over an hour later with Sue saying her body couldn't take anymore - she slept for nearly 3 hours. To be continued.
