To class

Alex realized that she hadn't actually gone to her class yet. She looked at her schedule to figure out what she had. "English - room 436 - Mrs. Ricks" it read. She started down the hall, unsure where room 436 was. As she walked, she passed other students, naked or dressed in the exposing clothing she was used to seeing in this world. They all took the opportunity to grab her butt or breasts, and since Alex was in no rush, she tried to return the favor. One boy she passed went even further, masturbating her for a few seconds before continuing on. She eventually found room 436, and she walked inside, unsure what to expect.

Alex stood at the door, shocked. Inside, all the students were in a huge daisy chain. No dick or pussy was unlicked as all the students recieved and gave oral to each other.

"Ah, you must be Alex," Mrs. Ricks said, stepping over the sweaty bodies on the floor. "Dr. Chen sent for you not too long ago." She turned to the oral orgy on the classroom floor. "Jane! Alex is here. Escort her to Dr. Chen's."

Reluctantly, a girl wearing a spandex bra and a light bush got up and walked towards Alex. "Hi," she began, "I'm Jane. This period I'm a messenger, but since you weren't here I joined in on the fun." She started glancing around the room.

"What's wrong?" Alex asked.

"Oh, I can't find my shorts. Oh well, who needs pants, right?" Jane said as she stuck a finger in Alex's asshole. "You like this?" Alex was too shocked to respond, and weakly nodded yes. Jane laughed and they walked on back to Dr. Chen's.

On the way, a bottomless boy reached and touched both Jane's and Alex's pussy lips. Just as quickly, Jane reached out and pulled on his dick. She turned to frown at Alex, who had only received the touch.

"You should've fondled him back," she responded. "What's wrong?" She smiled, and stuffed her finger deeper in Alex's ass, causing her to jump a bit.

"I'm just not used to it yet. I'm new here," she responded.

"I see. Well, here we are here," Jane said matter-of-factly. They both stood near the psychologist's office, looking through his large window. Inside, Alex could see her naked brother jerking off to a video. She leaned closer and saw it was a video of her and Dr. Chen having sex.

"How did he get that on camera?" she asked incredously.

Jane twirled her hair with her left hand as she massaged Alex's butthole with her right. "Oh, there are cameras all over the school to prevent theft. To prevent things like bribes and illegal behavior, they broadcast publicly to the school website so anybody can see them."

"That sounds like an invasion in your privacy." Alex responded, looking around for a camera.

"Well, we are in public. Anything that happens in public is allowed to be filmed without anybody's permission. And it has done good. My older brother got a scholarship when the college admissions people saw the post-football orgy in the locker room. He nailed every cheerleader and all his girl teammates, as well as me, two of his exes and this random lady who wandered in."

The door opened, and Dr. Chen walked out. "You can come inside now, Alex. Jane, come inside, I have an assignment for you."

Alex gulped and walked in. Pat and her looked at each other as Dr. Chen guided Alex to sit next to her brother.

"Now," he began, "both of you are aware, **** is perfectly acceptable here. In fact, feelings between siblings that otherwise wouldn't exist in your world are quite common here. This isn't a problem, except inasmuch as both of you think it is. I've talked to both of you, and you both have a lot of sexual tension built up. This is very unhealthy, and should be resolved immediately. Please start touching each other."

He crossed his arms, and Pat and Alex looked at each other, very nervous and embarrassed. Alex felt quite horny, but couldn't bring herself to touch her brother. It felt so wrong even though it wasn't.

Eventually she made the first move. She started stroking his rock-hard dick and tickling his balls a few times. He gathered up his courage and started exploring her breasts. "Good. Now both of you should stand up," Dr. Chen ordered.

Both siblings stood up, still holding each other. Alex started pumping at Pat's dick faster while he returned the favor by massaging her clitoris. Alex began moaning, and once Pat saw this, he stopped suppressing his groans of pleasure. Soon Pat reached for her soft behind and began feeling it. Alex kept pumping, getting hornier and hornier. Fuck it, she thought, I'll make the first move. She got really close to him, her nipples touching his chest, and redirected his dick to her opening, and slid it in.

Soon the moaning was impossible to stop as they passionately fucked. "Pat, cum inside her. Don't worry, she won't get pregnant." Pat weakly nodded as he continued to go in and out of his sister's pussy.

Soon a groan was heard, and Pat came, his penis lurching several times as it unloaded cum. Alex groaned, her mouth open and unable to close as she felt waves of orgasms wash over her. She started sexually recovering quickly due to the medications her doctor had given her, and she saw they were working on Pat too: his dick was already back at half-mast. They both looked at each other, relived, and then at Dr. Chen.

Alex giggled when she looked. Dr. Chen and Jane had been silently fucking to the scene, careful to not disturb the two lovers. When they saw the two siblings were done, they unmounted and finished themselves onto the floor.

"Excellent, you two really got into it. It was a bit too much for either Jane or myself to bear," Dr. Chen began. "As I was saying, I'm prescribing both of you a sex quota. To prevent sexual feelings from becoming barriers to normal living, you will need to have sex with each other twice a day for a month, at which time I will do another evaluation. I encourage you to fuck at least once at school and at least once at home." He pulled out two slips of paper. "Show these to your parents if they have any questions. My number is on it. This won't be part of your prescription, but I encourage you to continue to go nude or near-nude until we meet again, and try fucking in a very public place, like a mall."

Jane, still masturbating, turned to the psychologist. "Didn't you have an assignment for me?"

"Ah yes," Dr. Chen replied. He started scribbling on a piece of paper while talking. "Jane, I want you to go to one of their classes at least once daily and have sex with them, asking about how their sex went. Be understanding, since they're both virgins, and give them lots of pointers."

Pat spoke up. "We aren't virgins. And if we were, we aren't now."

Dr. Chen smiled. "Yes, in your world. But here a virgin is somebody who was only been having sex for a year or less, or isn't quite adapted to a normal sexual routine in our world. Now first period is over, but I encourage you to try fucking at lunch today. Enjoy second period."

Both Alex and Pat walked out, feeling quite relieved as they looked at each other. They noticed Jane wasn't with them, and looked back to see Dr. Chen fucking her doggy-style. Alex giggled to herself. Pat simply smiled.
