A couple of months ago, Sissy, who is married to my brother, had gotten herself deep into debt by the overuse of her credit cards. She didn't want her husband to find out, so she asked me if I would lend her the money to clear up her debts. I agreed, but I told her that thought she would have a hard enough time paying back the loan and badly needed to learn a lesson in money management. So I made her agree to pay interest on the loan by being my personal sex slave on a once-a-week basis.

Every Thursday night after my wife had left for class at a nearby evening college, Sissy would arrive at my house. I would make her strip down completely and crawl on all fours to the top of the second floor stairs, where I would be waiting. I would be her master for the evening.

The sight of her thirty-eight inch melons swaying back and forth as she crawled ignited both my cock and my plan of action. For when she got to the top of the stairs, she would then crawl on her belly to the foot of my bed, where I made her kiss and suck each one of my toes. She was good at it too, very enjoyable to watch her doing that.

While she sucked my toes, I would snap the first of many pictures, which recorded the night's action and would be my ultimate insurance that the loan would be repaid in full and also to keep her from telling anyone about our arrangement, like my brother.

With the preliminaries out of the way, I always place Sissy on all fours on my bed and then push her head down into a pillow and tie her hands, over her head, to the headboard. Now I am ready to work on her pleasingly plump ass with its tight little hole.

Using bright pink lipstick, I would paint the brown little bull's-eye pink, and then using the brightest of red lipstick, I always write in big letters "FUCK MY ASS". As soon as I have recorded this scene with my camera, I mount her quickly from behind, shoving my straining cock in as far as it will go up Sissy's Hershey highway.

The bright pink lipstick is the only lubricant she gets. I want her to feel some pain in order to understand the evils of being literally up to her ass in debt! As soon as I have cum deep inside her bowels, I untie her hands and flip her over and then tie her spread eagle on the bed.

The second phase of Sissy's slave duty begins as I coat the inside of her pussy with something hot and tingling like mouthwash or horseradish. Next, I tape plastic bags full of ice cubes to her 44DD tits. The alternating hot and cold sensations flowing from her pussy and tits to her brain make her as cock hungry as a nympho doing a life sentence in solitary.

The best way to satisfy her cock hunger now is to stick my cock right down her throat. I straddle her upper torso. While I hold her head immobile with my hands, I fuck her mouth until I shoot and my cum is oozing out of the corners of her mouth. As soon as I capture this image with my camera, and she has licked all of the cum from her face and swallowed it, it's time for the final phase of Sissy's slave duty.

Out of my wife's dresser came the biggest thickest vibrating dildo, which I use to tantalize Sissy, touching her almost everywhere except on her quivering clit. Sissy's hips are bucking wildly as if she were a bitch in heat. At the same time, she starts to scream at the top of her lungs for me to cunt fuck her as hard as I can.

But since I have decided that she won't get my cock in her cunt until she has repaid the loan in full, I ignore her pleas for a good hard fucking. Instead, when I think that she can't stand anymore teasing, I again fuck her in the mouth and when I'm ready to cum again, I quickly pull out and jack-off all over her face. Then I untie her and send her home, and I again become the good and faithful husband for my wife. She has no idea what goes on when she is at her weekly class.

Oh, and by the way, as a result of our weekly sessions, Sissy is repaying her loan faster than I had ever expected!

The End
