Some identical twins struggle to retain a sense of individuality. They'll style their hair differently, dress differently... anything they can to differentiate themselves from their sibling. But Lisa and Nancy were different. They reveled in their similarity. Growing up, they vexed their parents because it was never possible to discipline them when they were naughty behind their parent's back - it was simply impossible to know which of them was guilty. They shared everything. They ostensibly dated separate boys in high school, but secretly they swapped occasionally to share notes. After graduation, they applied, and were accepted to the same campus of the state university. Though they had been assigned to different dorm rooms, they talked one of their assigned roommates into swapping so that they could live together.

The two of them were proud of their looks. They were striking redheads with green eyes. Both 5'5" and 110 pounds. They had wide hips and 34C breasts. They had the same dimples when they smiled, which was often at the same time. They generally wore little make-up apart from a little bit of lip gloss. Since they were freshmen, all of their courses were introductory classes, most with hundreds of students. Even so, they stood out. They always dressed similarly, if not identically. They were used to being gawked at, but when asked they said that although they enjoyed being at the center of attention, they didn't mind sharing the spotlight with their sister. To them, it was the perfect balance.

It was during a lab for a particularly challenging computer science course that the two sisters met Keith. He was a computer science major and helped the two girls with their lab project. Though he was a self-admitted geek, he was tall, had handsome features, blonde hair and wore a leather jacket. The two girls both liked Keith. Most guys they had dated had been a little bit freaked out, but Keith seemed to enjoy the ambiguity. They spent a lot of time in the computer lab, with Keith helping them out with the subjects he was good at. He quickly gave up on telling them apart and simply called one of them "Lisa" and the other "Nancy" without making sure he was talking to the correct one. The girls were so used to trading identities, they didn't mind. One day, after they had finished, he cleared his throat and said, "Hey, I want to ask you two something. I want to ask you out on a date. But... this is a little weird. I can't tell you two apart, and you're both so much fun together, I don't really want to. Would it be weird if I asked you both out for a pizza?"

The girls looked at each other and smiled. All of the boys they had dated before had been a little freaked out by their interchangeability. But Keith seemed different. Maybe they could share him after all. They both nodded and said, "Sure!"

Keith grinned, but then added, "I still don't know which of you is which. If I just were to pick one name to call you both, which would it be?"

The girls had never really considered that. People had always insisted on using their separate names. Keith's suggestion had them at a loss. They both looked at each other. One of them said, "I dunno. I guess Nancy?"

The other spoke up and said, "Either is fine. I'm actually Nancy, but if she doesn't mind, it's ok with me."

The first girl smiled and nodded. Keith smiled and said, "Alright, Nancys. I'll meet you at Granite Pizza at 7."

--

The girls arrived at the pizza place on time. Both had on jean shorts and white T shirts that they knotted at the bottom to show a little bit of their midriffs. As usually happened, lots of heads turned to see the two identical knockouts walk through the door. Keith was waiting for them by a corner booth and waved them over.

"Hi, girls! Glad you could make it!"

They both smiled and said "Hi, Keith," at the same time.

"How do you two always do that?" he said and smiled.

The waitress came and they ordered a pizza and sodas. They talked about their classes, and about their favorite bands... the evening flew by and before they knew it, Keith had paid the check and invited them back to his apartment.

Once there, he turned on his stereo and played some dance music. The three of them danced wildly. The girls laughed sometimes at Keith's moves, but he laughed with them. The music changed to a slow number and for a moment, Keith wasn't sure what to do. He reached out to one of the girls and put his arms around her and they started to dance together. The other sister stood for a moment. She watched her sister dance with... their man. She started to feel jealous. She walked over to her sister and tapped her on the shoulder, saying, "My turn."

Her sister smiled and stepped away from Keith while the other girl took over. Keith danced with her just as he had danced with the other, but the girl who was dancing held Keith closer. Keith moved his hand lower on her back, moving closer to her ass.

Now the shoe was on the other foot, and the sister that was left out felt the jealousy flare up inside her. His hand was on her ass! Secretly she wished it was on her own. She shouted, "Hey!"

The two dancers stopped and looked at her. She didn't quite know what to say next. Keith spoke. "Ok, I can see what's up." He walked over and turned off the stereo. "Both of you. Sit down." He pointed to the couch. The two girls looked at each other and sat down.

"Girls, I really want this to work. I've really got feelings for both of you. But we're going to have to nip this jealousy in the bud right now. There's one of me, and two of you. My promise to both of you is that I will do my very best to treat you both equally. But there's going to be times when I can't treat you equally at the same time, and that means you're going to have to wait your turn."

As the two of them listened to him, they looked at the floor. They knew he was right, and were ashamed of themselves.

One of them said, "I'm sorry."

The other said, "Yeah, me too."

Keith folded his arms, "I don't think that's enough. Come with me." He walked out of the room and down the hall. The two girls looked at each other, stood up and followed him.

He arrived at the bedroom. Inside was a queen bed. The wall next to the bed was a pair of mirrored sliding glass doors. He ushered them over to the side of the bed next to the closet.

He said, "I think we need to nip this jealousy thing in the bud. I think the two of you need a spanking."

He let that thought hang in the room for a moment, while the color drained from the two faces in front of him. The two sisters nodded and looked at the floor.

"And just to bring this lesson home, you're going to spank each other." He pointed at the sister closest to him and said, "Stand up and drop your pants and get over your sister's lap."

She looked at her sister and slowly stood up. She reached down to her pants and unsnapped them and pushed them down her hips. She leaned over and positioned herself over her sister's lap. The seated sister looked over to Keith.

He simply said, "Go."

She looked down at her sister's panty clad ass. She took her right hand and brought it down sharply on her sister's ass, bringing a yelp.

Keith said, "Harder! Remember how you felt watching us dance!"

He said this and the image of watching her sister dance with her man filled her mind and the jealousy flared up inside her again. She brought her hand down harder on the opposite cheek, bringing another cry from her sibling. In her mind, she made a direct connection between the jealous part of her mind and her hand, bringing her sister to tears. After a few moments, she slowed down. The spanking had emptied her mind of the jealousy. Her sister sobbed over her knee, her as cheeks visibly pinker through her sheer panties.

Keith spoke, "Alright. Switch places."

The spanked sister stood up, sniffling. She looked at her sister, clearly angry. The first sister felt a pit open up in her stomach, feeling guilty both about the jealous feelings she had had and the spanking she just gave her sister. She stood up and lowered her own pants. Her sister grabbed her wrist and yanked her down into place. She didn't wait for Keith's urging and spanked her sister hard from the start. Her head flew up with the spanking and she cried out. As she felt the fiery rain of spanks on her ass, she caught a glimpse of herself over her sister's knee in the mirrored closet doors. It almost looked like she was spanking herself. But she had no time to dwell on the scene. The spanking continued, the upright sister extracting her own vengeance for the spanking she had just received and for the jealousy she had felt. As she spanked, as her sister had before her, she felt the anger and jealousy flow from her mind to her hand to her sister's ass until she calmed down. As she had done before, her sister cried over her knee. She stopped and looked back at Keith.

Keith spoke again, "Alright. Stand up and come here." He embraced them both and they shared a group hug. He kissed each sister in turn, and then asked, "do you both feel better now?"

They both nodded and looked back at him. He took one hand from each sister and gradually eased them down towards his crotch, and asked, "How much better?"

All three of them smiled.
