Things were relatively quiet for the next couple of weeks. Our her classes except calculus but she was doing better. She also managed to enjoy the other aspects of college life without succumbing to any of the darker temptations and would've made any parent, real or temporary, proud. The only spankings that occurred were on my wife's lovely bottom and in the privacy of our bedroom.
A word or two about those occasions. Although we almost always started out with her over my knee we found that adding the finishing touches while she was kneeling on the edge of the bed with her rear end raised and ready for immediate penetration was especially enjoyable. Even though the swats were just enough to get her nerves to sting a bit I would describe how I would spank her if she was really getting punished. I suppose this is an indirect violation of my rule about finding that kind of discipline enjoyable for any of us but the sharp snap of my fingers and her imagination got her quite prepared for my entry so it was worth it. However, the last time we engaged in the spanking/lovemaking process she took over the narration during the spanking. She started by saying how we should spank her sister and after a while I joined in with a few suggestions of my own on what we would make her do and how my hand would bounce off her tight skin. We were more than ready when my hand stopped demonstrating how it would bounce and other parts of me took over. The bottom line (if you'll excuse the pun) was that we were both looking forward to when we'd have the opportunity to redden that young bottom. I was still very sincere that if she, and I mean either she, was over my lap to atone for some real misdeed there would be nothing sexy about it but what we had in mind was getting her to agree a non-punishment spanking. So we tried to figure out how to bring up the subject. As it turns out, we didn't have to do anything.
The next night we were sitting in the living room and trying to decide whether to watch a movie or find some other way to occupy ourselves. My sister-in-law interrupted the discussion to say, "I don't know if I've told you lately but I really appreciate you letting me stay here. I hope I haven't been a burden. I know Dad sends you some money but I wish there was some way I could repay you for your kindness."
My wife and I looked at each other and wondered Our boarder had said she was willing to be spanked for our entertainment as a way of showing how grateful she was for us allowing her to live here. Was that what she was suggesting?
She continued, "I needed that spanking you gave me for screwing up in calculus and I thank you for it. I've been doing my best to be a good guest and I guess that's why my sister hasn't gotten to see me get spanked since then."
She was looking down as she finished. This was as close as she was going to get to actually asking to be spanked but her meaning was very clear. She didn't just interrupt our discussion about choosing the night's leisure activity. She had completely stopped it with an offer we couldn't refuse. I moved from the couch, repositioned the spanking chair and sat down.
I said, "We'll fix that right now. Get up. You're going to get spanked."
She slowly raised her head and I almost believed her chagrin as she said, "But I haven't done anything wrong. I don't want a spanking."
As I said, I almost believed her until she cracked a little smile to let me know that I didn't misinterpret her comments earlier. She wanted to play and although I didn't know the exact rules I was willing to go along with the game. I was falsely stern and said, "I don't care what you do or don't want. I said I'm going to spank you and that's what's going to happen. Take your clothes off."
She ignored my command and climbed onto my lap while saying, "I was thinking about just a little spanking over my jeans and then going up to my room early."
I put a hand on her rear end and said, "You were quite willing to let my wife be nude when I spanked her and that set a precedent I intend to follow. We'll start with you fully clothed but make no mistake, you will stand naked in front of us before the night is over."
I didn't start spanking right away. I let my hand roam around the surface and appreciate the firm softness and it's nice round shape. It wouldn't do for me to say it was the nicest rear end I ever fondled; my wife held that honor but it would rate right up there with the best. As I gave it a little squeeze I thought about what she might be feeling. Her father's hand had made numerous impressions on this surface many times so I knew mine wasn't the first male hand to be in contact with that part of her. This wasn't even the first time she was over my lap with her bottom raised. Still, I had a hunch this was a new experience for her. Surely she had engaged in some petting on dates and I suppose she might've let a boy put his hand on her rear end while dancing but that would be quite different from being in this position and feeling someone caress that part of her quite so gently and intimately.
My first swat startled her. I know it didn't hurt through all those clothes but I had inadvertently lulled her into forgetting why she was over my lap. I promised a light spanking but with two layers of clothes for protection I didn't think a sharp spank or two was out of line. After a dozen or so I raised her to her feet, unsnapped her jeans, sent them south and pulled her back down. Her rear end was so cute wrapped in white panties. I briefly considered starting all her spankings over her panties but my admonition about not deriving pleasure from someone else's punishment applied to me also. If she was in this position for good reason I would forego the enjoyment of the lovely gift wrapped package presently raised on my lap. But that was then and this was now so I again gave my eyes and hand free rein to explore before slapping down.
The landings weren't hard but I could see that a few of them stung a bit. When that happened I would stop and rub the surface to remind her that she was not being punished. I gathered from her soft purrs that she was not dissatisfied with the way the spanking was going. More swats and more caressing and it was time to get more serious. She had told us about one of her favorite fantasies and in that make-believe world the fellow pulled her panties down and she received more spanking before the clothes gathered about her ankles were removed. I skipped that part and had her step out of the jeans. In real life she always bared herself but I let her enjoy the lack of responsibility and all she had to do was stand passively as I put my fingers into the waistband of her panties and slid them down her legs very slowly. Her only active participation was to lift one foot and then the other to facilitate their removal.
As I was about to guide her back down she stepped back and asked me to wait a minute. She retrieved her jeans and took a note out of the pocket which she gave to my wife. As she read it she smiled broadly but didn't share the contents with me. It had something to do with the spanking and was written before we started our discussion so I came to the obvious conclusion that she had done some preparation for the evenings activities. I found out later just how much she had prepared but I don't want to get ahead of myself.
When she was back in place I looked down at her. It was a view of her I had seen before. Bare bottomed and ready to be spanked. The difference was that now she was already developing a healthy glow. Her rear end was nice and pink and ready to continue its transition to a deeper color. That alteration of hue took about ten minutes with the repetitious cycle of a few spanks followed by caressing, rubbing, gentle squeezing and back to spanks.
My wife wasn't a disinterested and inactive observer. She had managed to unsnap her bra without taking off her blouse and although I couldn't see her hand, the movement of the fabric covering it was enough to let me know what she was doing. The other hand was more obvious in its activities. Did I mention that just after her sister lost her pants and panties she shucked hers too? She was unclad below the waist and blatantly masturbating for us. I was slightly distracted by watching her and the girl on my lap told us later that seeing how much her sister was appreciating the show made it even better for her. Which is not to say that she didn't like the other things going on. The sensual nature of this kind of slow erotic spanking and the spreading heat from her back side to her front side were getting her extremely aroused.
When she was upright again she followed the family tradition of not putting a hand on her red bottom but she felt putting her hand in close proximity on the other side of her was acceptable and very desirable. However, I slapped her hand away and said, "None of that until you take everything off."
Unlike the story she told us where she reluctantly removes her T-shirt, tonight she had it off in no time. I would've thought she would want to finish the job quickly but she stopped just short of baring her breasts. I wasn't sure whether she was going back to her fantasy or was actually shy about showing them but one hand was holding her bra tight against her chest and she shook her head. "No. I can't do it. Haven't you humiliated me enough? Leave me this one shred of decency."
Aha. We were back in her fantasy. My wife stopped her self-pleasure and held up the note. I still couldn't read it but she pointed to it and then to the drawer where we kept the strap. Did the note say I was supposed to continue the spanking with the strap? That didn't fit in with my idea of a sexy spanking but I went to the drawer, opened it and smiled. Now I understood. Lying on top of the feared strip of leather was a long plastic tube. Battery powered.
The almost naked girl had her eyes closed, was bent at the waist and her feet were already rather far apart when I returned to her. She shuddered visibly when she heard the tell-tale buzzing but it wasn't a reaction to fear. She bent lower and thrust her rear end out even farther. Given the state of what she was prominently displaying it was obvious to the most casual observer that the vibrator would have no trouble gaining entry and it didn't. She moaned as it slid all the way in and made a slightly different sound as it came out. Another purr of pleasure when I moved the tip of it against her special spot and then frustration as I took it away. Her gyrations as her hindquarters searched for and hoped to recapture it were delightful. Then I did the probe, tickle and run away two more times before the precious bra fluttered to the floor and she reached between her legs to take command of the vibrator. I added a few spanks as it was going in and out and drove her higher.
My wife joined us and moved her sister to a more vertical stance. She said, "You've got to see this. I'll take over back here."
Taking over meant she applied the inspirational spanks while I watched a young woman with two busy hands. One was tweaking her nipples and you already know what the one with the vibrator was doing. It was a lovely sight and in deference to her sister, my wife waited until I had an eyeful of the hitherto hidden breasts before adding two more to my vision. Now there were two naked females in the room. One masturbating to beat the band and the other spanking her with one hand while the other (hand) was raising one of the two most recently exposed breasts towards me. I moved closer to take advantage of the offer and was attacked. I guess I did look out of place as the only one with any clothes on but three sets of hands and fingers quickly resolved that problem.
I hadn't fully considered just how I was going to relieve my own tension in these sessions. Last time I took my wife into the kitchen but I didn't think that was in the cards tonight. This is probably a male thing but while I was quite happy to watch them play with themselves I was shy about doing that to myself in public. Luckily, I didn't have to cross that bridge. Instead my natural inclination to have sexual intercourse with my wife in relative privacy was compromised. I ended up on my back with two familiar lips sliding up and down my erection while the previous star of the show was also on her back a few feet away. She (the one on her back) was lying so she could see us while as she (and the vibrator) went back into action. In my helpless(?) state there was nothing I could do to prevent someone from straddling me and impaling herself. This was totally unacceptable so I rolled us over and ravished my wife in the more dominant male on top position. After all, a man has to maintain his authority in his own house.
It was a lovely evening but alas, not repeated for a long time. There was a direct correlation between the reason for that and why our houseguest suggested the event and I guess I can tell you about it. I should warn you that you're getting the story third hand. My sister-in-law confided to my wife who told me in confidence and now I'm telling you. Please don't let anyone know you heard it here. O.K? It takes place over a period of time and to be honest, I'm not sure I have all the facts and chronology right but you'll never know the difference anyway. Likewise, anything I'm not sure of I'll make up as I go along and you'll be none the wiser. Tee-hee.
