That night Bill called to make sure our clothes had arrived and if we liked them. He seemed pleased we did and didn't complain about how revealing they were. He said the heart cutout would make all the women jealous of our trim tummies and little waists. That prompted Mom to say that she was surprised that the dresses were so sexy. She assumed people at country clubs would be stodgy.

Bill explained that this ball was for young people and since Mom could pass for twenty-five she would not be out of place. He said he would fly in to get us about five then we would have dinner at his folks place then we could dress for the dance.

We landed at Seattle then we drove to their house. It wasn't a house. it was a mansion. Suddenly Mom connected with Bill's last name. "You said your dad was a lawyer. He is our Congressman! I remember this house from a magazine."

Yeah, but Dad prefers being thought of as a lawyer because that is where most of his money comes from.

We were really impressed. Dinner was fabulous served by a maid and his folks were really nice. They apologised that they would not be going to the dance because they had to fly to Washington later that night. They left after a few after dinner drinks and Bill said we should get dressed.

When Mom and I were alone dressing she said, "God Susan. They liked us! Do you know how great this could be for you if Bill would love you as much as you do him? Whatever he wants, you should do it."

I thought I would test her. "What if he wants sex?"

"That is alright just let him know you are doing it only because you love him. God, I wish I had talked to you about sex. Just remember even things that may seem strange are alright as long as you both like it."

I was enjoying this! It seemed like everything I had done with Bill was alright.

"What do you mean by strange?"

"I only know what your Dad likes. Sometimes he likes to be kissed down there."

"What do you mean down there?"

"Oh you know. You are embarrassing me. He likes to have me kiss and suck on his penis. It isn't so bad. it is clean."

"I heard about that in sex ed. Anything really strange?"

She blushed like a school girl. "Well sometimes he likes to spank my bare bottom. It doesn't hurt really. Just a little sting and it really excites him. Me too."

She had not put the dress on yet and her cute round buns were bare except for the string going up her crack. I could understand why a man would enjoy the submissiveness of a woman who would let him spank them. I also could understand how it could excite her. The little pain from Bill pinching my nipples and lightly slapping my boobs had just added to my excitement.

When we dressed Bill was waiting for us in the front room. He said we looked fabulous and we pirouetted in front of him giggling that he was so pleased.

The dance was great! We did not feel out of place at all since a lot of girls were dressed even sexier than us. Some wore gauzy dresses that you could see their panties and nipples through and one girl must have been really proud of her cute round butt because she had an upside down heart cutout on her back that bared the top of her butt-cheeks. When her boyfriend danced with her he put his hands under her dress to squeze her bottom.

We danced a lot! Me mostly with Bill but Mom was asked by boys much younger than her and was flattered by the attention. We both drank a little too much and got a little silly. I had never seen this side of her. She loved dancing and made no objection when men would hold her bottom to pull them tight against their bulging crotches.

Bill noticed we were getting drunk and excited so he said we should go home.

When we got there Mom scurried to the bar to make us drinks while Bill turned on the stereo. A good song came on and Mom and I started to dance.

Bill encouraged us by applauding and saying we looked great. We giggled and made some sexy moves. When the next song was faster Mom leaned forward and shook her breasts. They fell out of her dress! She just giggled and said, "Whoops" and began to put them back in but Bill yelled, "Leave them out! They look great!"

She did! I began to feel left out with him staring avidly at her bouncing boobs. I unzipped my dress and let it slide to my waist. I tucked my bra under my boobs to bare them completely to have them bounce and swing to the music. Now I had his attention and when Mom noticed she also let down her dress top and took off her bra.

It became a contest. Soon we were dancing close to him so he could take off the rest of our clothes one by one until we were naked then he danced with us while we removed his clothes.

When he was naked he dropped to his knees pulling Mom down with him then laid on his back and pulled her down on his dick. I again felt left out until he pulled me down on his face to lick my pussy.

I was facing Mom. She had this look of wild ecstacy on her face and was pinching her nipples and lifting her breasts until her nipples had hardened to look like little thumbs. I tried it and found my excitement jumped even higher until it was obvious we were in full orgasm.

Mom began letting out little screams and then slumped to sit shuddering on his dick. Suddenly her face clouded and she began to cry. She jumped up and ran to our room practically howling in grief.

I was glad to see her go. Now I had him to myself and I laid on him to kiss him and lick my juices off his face. Then I slid down his body to lick and suck on his dick so I could get it hard to climb on it. It wasn't working. He just laid there breathing hard but his dick stayed soft.

"What is wrong? It isn't getting hard."

"I am not Superman. That was a real workout. I am going to need a rest or something really special to get hard again."

I locked onto "Something special."

"Mom said Dad got real excited by spanking her and that it didn't hurt much. Would you like to try it?"

"Really! Tell me about it."

"She didn't give me any details. I guess you could do it any way you think it would be exciting."

"When I was a kid a girl told me she hated Catholic school because the Nuns would tie their hands above their heads and a girl would hold up her skirt while the Nun spanked her with a strap. The idea excited me. Would that be okay?"

"Oh God! That sounds like it would hurt but it might be even more exciting for you since I would be naked. I guess it would be alright. I know you won't hurt me too bad."

"We are all set for this. The chandelier has a winch to lower it to change bulbs. We can use it to tie you. Tie your stockings around your wrists while I look for a belt."

I became excited as I used my teeth to tighten the stockings around my wrists. I realized this act might make me unique. Some of the girls at the dance were as pretty as me and rich but I was sure those spoiled little bitches would never let him hurt them. I decided that even if it didn't hurt much I would act like it did so he would know the great sacrifice I was making for him.

He came back down with a wide thick western belt he was cutting in two to make an eighteen inch strap.

I was hoping he would just use his little dress belt but it would prove my love better if I suffered more.

He lowered the chandelier and I held up my hands so he could tie the stockings to it and pull me up until I was on tip-toes.

It felt good to be stretched and exciting but I thought I would remind him of the sacrifice I was making.

"Oh. I feel so helpless. I am at your mercy. You know I would never let you do this if I didn't love you so much. I'll bet no other girl would allow it."

"Yes I know you are proving your love but if it doesn't hurt it won't prove anything will it?"

"No. Make it hurt. I promise I won't ask you to stop."

"Good. Your body looks fantastic stretched like that. Let me show you."
