Kim's Penance

As I drove I began to think about the deal that Kim and I had made for no sex until Friday. The penalty we had agreed would be some sort of sexual penance. But what kind? As I began to think the problem over my mind wandered back to the pleasure I had gotten from watching my sister Karen get it on with her friend Liz. Why not tell Kim that she was to arrange to put on a show for me with her fifteen year old sister . That sounded great and maybe they could perform like Audrey and Sue had as well, maybe I should fuck Kim's ass just as I had done to Lucy too. My cock was throbbing urgently again and I shifted to thoughts of work a couple of blocks from home so my cock wouldn't betray me.

When I came in Kim and Mike were fully dressed. Everything appeared normal except Kim seemed a little standoffish. Mike, Kim and I talked for a couple of hours and then it was time to take him to the airport. Kim and I drove him out and saw him off.

On the way back I asked Kim how her afternoon had gone. She only said, "Fine." I tried to get more details from her. She told me they talked beside the pool but she was evasive as to what they discussed. She never could lie. I told her that I hoped she and Mike had lots of suntan lotion on. Her faced turned quite red at this line. She knew the jig was up but said nothing.

I proceeded then to tell her that I had spent the afternoon dreaming about a young woman seducing a sixteen year old beside a swimming pool. How she had a really skimpy bikini on and how she had coaxed him to spread suntan lotion all over. How she gradually ended up undressed and him massaging her all over. How she became so aroused she had to finger herself off. How she had shown him how to finger her off and how she had brought him off manually and with her mouth. I told her the thought of it had almost caused me to break our "Sexual Celibacy" agreement.

Kim finally blurted out that Mike was just too much. She couldn't stop herself and while she regretted breaking our agreement she was really glad I had enjoyed the show so much. "Did you know he was still a virgin." Kim added and that surprised me. "He has an immense cock too," she went on, admitting that he was as big as Robert. She seemed to be getting excited again by her thoughts of Mike.

"What about our deal though?" I interrupted. "What sort of sexual penance are you going to do?" She was a little taken aback by this side of our bargain. "A deal's a deal." I reminded her. "What else had happened after the lotion episode?" I asked. She maintained sternly that nothing else sexual had taken place than what I had seen. I was relieved I hadn't missed anything. We were almost home and I said I would think up something before bed time. My mind was flashing back to my plans I had made that afternoon after I had snuck out of the house after my spying on them. I let her worry though.

Kim seemed pretty nervous over the rest of the evening anticipating what I might tell her she had to do to atone for misbehaviour with Mike that afternoon.

Finally at nine I took her aside and told her she should take a quick shower and return to the den in the nude ready to do her penance. She seemed mystified but did as I had directed. I stripped off my clothes and put on a short house coat. I retrieved a tube of KY jelly from the guest bathroom.

I waited for Kim anticipating how it would feel to fuck her tight little asshole. My cock swelled with anticipation. Kim finally peered around the corner into the den. She asked me if I was ready for her to do her penance. I certainly was I assured her flinging back my house coat to display my erect manhood. She oohed and pranced into the room nude.

I told her that I was glad she enjoyed being a fuck sandwich for Paul and Robert the last weekend and I had really enjoyed fucking Lucy's ass so I had decided to try hers. She blushed and timidly asked if she had to. I told her in no uncertain terms that that was to be her penance. "If I must." she said but first I directed her to make my cock really hard by sucking it. She had no problem with this and sinking to her knees began to lick and suck in earnest. She was doing a wonderful job and I nearly forgot what she was preparing me for. In fact I wasn't sure she figured if I blew my load down her throat her asshole would be spared the reaming I intended for it.

Finally I pushed her away and told her kneel on the edge of the couch. She climbed up on the couch and with her knees on the edge placed her forearms on the couch back exposing her gorgeous ass. I stepped up behind her and took some KY jelly and having greased my middle finger, slipped it easily into her asshole. She moaned. I finger fucked her asshole for a minute than add a second finger forcing her open even more.

Next I withdrew my fingers and slipped my erect prick into her cunt. She groaned with pleasure at this turn of events and I proceeded to plow her cunt. She felt wonderful and tight but this wasn't what I had planned and slipped from her. I placed the tip of my cock on her puckered asshole and eased my red hot prick passed her sphincter until I was deep in her shit hole. She was really tense and tight. I told her to relax a little and began to gently push and pull my cock in and out of her. Each time I pushed into her I could feel a wonderful back pressure pushing down my cock to my prostrate and the need to release my load of come became more urgent. In only a matter of minutes it was too much and with one last push I began to spurt off deep in her bowels.

I didn't remember a lot after that but collapsing, spent and totally played, out on the couch beside her. Kim did give me a gentle kiss and thank me for being so gentle. She whispered in my ear that if that was ALL it took to repent of her digression with my brother I had better watch her more carefully in future. There seemed to be a special meaning in this. She seemed to be saying that she really enjoyed her ass fucking and my watching her making out with Mike.
