I was startled by Bobs voice.

"Seeing the woman at the restaurant was quite a coincidence. In the top drawer of the cabinet in the hall you will find two black boxes. Get them and bring them here."

I ran over to it and brought them back to him He took them from me and opened them then handed one to me and one to Mom.

"If you have decided to stay with us we would like you to wear these as a sign of your commitment."

I looked into the box. There were two large rings with tags with Tim's first and last initial and six smaller ones laying on black velvet. They were beautiful.

"Oh of course I will wear them! You know I am committed to you Tim. I am only sorry I can't show them to the world!"

Mom joined in, "Yes I will wear them even though I know how much it hurts to put them on since Kay's dad had me wear them. Could I have this favor? Would it be alright if I put some ice on my nipples to numb them a little before you do it and can we just do two of them per session? If that is alright we can do my nipples tonight."

Bob answered, "That would be acceptable. Go get some ice. The needles are under the velvet."

I looked under the velvet there were two large gold plated needles for the large rings and two smaller ones for the other rings I knew would be put in the lips of my pussy.

I watched in fascination as she rubbed ice cubes on her nipples until she said she was ready. Bob slowly pushed one of the needles through her left nipple as he stretched it out by holding onto the tip. He left that needle in to keep the hole open until the bleeding stopped and repeated the operation to the right needle. Finally he put in the rings. They looked great and I reflected on the fact they showed a commitment much stronger than any engagement ring could. I decided that it could not have hurt terribly as Mom never screamed or sobbed. Her only reaction was a tremor going through her body and tears falling from her eyes.

Tim offered me the ice but I refused. "No! I want them super alive for this. The more it hurts the more I can prove my commitment. Tie me to the center post and whip them with ten lashes and then put them on."

He tied my hands behind the post then put a belt around the post and my waist to hold me in position. I felt my pussy getting wet as he shook out the thongs and slowly brought back his arm as he aimed at my hard nipples. I was panting with excitement as I watched the first lash compress my breasts as the fire began. The sting and burning rose along with my excitement.To my surprise the piercing was an anticlimax. My nipples were stinging and burning so much from the lashing, the pain from the needles being pushed through them was not bad at all. I came as they were being pushed through and I could see little drops of blood dripping off the ends of the needles while he got the rings and put them on. Then to keep me at the peak of my orgasms he knelt and began to lick my clitoris until I spaced out and ended up hanging by the belt around my waist.

We celebrated by getting drunk while we entertained them with belly-dancing and bump and grinds. Later Tim suggested we demonstrate our technique in performing sixty-nine on each other. Bob agreed and added, "We will make a contest to see who is most sensitive. The first one to get off will get a reward the other will be punished."

Mom must have really wanted to win because she faked an orgasm before I was even close. I protested and Bob agreed.

"Come on Kathy! You have not been brought off that fast in your life. Admit you were faking!"

"Yes, you are right. I'm sorry. I didn't want you to think I was not sensitive anymore because I am older."

"Well you deserve to be punished both for lying and for cutting an activity short that Tim and I were really enjoying.

They tied her with her face out. Her arms and legs were stretched and spread.

"This is an item we have not tried before. You may hate it or like it. It is an electric cattle prod. The man at the store said it was about the same as grabbing a spark plug on a car."

Mom watched wide eyed while he pushed it against her inner thigh and pushed a button. She screamed and fought against the ropes.

"Obviously you don't like it there. Maybe it will be better closer to your pussy."

He held it against her other thigh very close to her pussy and pressed the button again. Again Mom just screamed louder as she fought the ropes.

"Let's try it here."

As he said this he held down the button and pressed it against her right nipple. While she was still screaming he put it on her other one."

Her body went rigid and then slumped as she sobbed and babbled, "No, no, no, please no more."

Bob stepped back and let her calm down. "You seem to be very sensitive to electrical shocks. Because of this if you ask me nicely to give you one more on your pussy it will be the last one forever."

Moms eyes jumped open as her body became rigid again as she moaned, "Ooooh nooo. Not there it would kill me."

"Alright then if that is how you feel."

He stepped behind her and held the button down as he jabbed it into the cheeks of her ass over and over. The muscles in her butt tensed with each jab and she began to scream again. Then he stepped back in front of her and stood there calmly until she opened her clenched eyes and saw him.

"Oooh you are going to keep doing it until I ask you to do it to my pussy aren't you?"

"Well not forever, but there are a lot of places I haven't touched yet."

"Alright go ahead and do it." she said in resignation.

"That is not asking me nicely." he put the prongs between the lips of her pussy just below her clit and held it there with his finger off the button.

Mom took several deep breaths and bracing herself said, "Please do it to my pussy." Her tremors must have made it touch her clit because her scream changed to a screech and she slumped in her bonds in a dead faint.

We helped get her down and Bob carried her to the couch. I was amazed that something could hurt that bad without leaving a mark except for bruises on her wrists and ankles from fighting the ropes. I am ashamed to say it made me very excited to see her tortured that much and I pulled down Tim's shorts and got on my tip-toes to jam his prick into me. It had excited Tim too so he was happy to accommodate me. The surprise came when Bob came up behind me to drive his humongous tool into my anus. This was a new experience and I loved it as I was mashed between them and completely filled internally. My excitement grew and I came just as their dicks started to soften. I was so grateful I cleaned both of their dicks with my tongue in spite of the fact some of my shit was on Bob's.

I laid on the floor between them while they idly played with my nipples and worked their fingers into my pussy until we heard Mom letting out low moans. Bob went over to hold her while she cried, "Oh Bob. You must hate me to hurt me so badly."

"No Darling, I love you more than I can say. It is just important to me you never say 'No' to me."

He kept kissing and hugging her till she was smiling and crying at the same time. His lips were working their way from her breasts toward her pussy when she said, "I'm sorry. Of course you are right. I told you I loved you and would do anything for you then I lied to you by faking orgasm and complained about punishment I richly deserved. Do you forgive me?"

"Yes I will always forgive you when I feel you have been punished sufficiently. People react differently to shock. I thought you might get into it. My wife used to push her nipples into the electric fence till she came."

"Well maybe it is too impersonal since it is just a machine that works at the press of a button. Maybe if there were wires attached to it you were whipping me with I might react differently."
