Sid was surprised when his archaeology professor asked to seem him after class. He was doing well in the class. He couldn't be in trouble, could he? Ms. Kane's cheerful expression when he approached her dispelled his fears, but he was still confused.
"Don't worry, it's nothing bad. I have an opportunity I'd like you to help me with, if you're willing."
"What, like, extra credit? I don't think--"
"No, no, no. That would be... improper in this case. Come with me to my office, so we can talk about it in private."
Sid couldn't help observing her body as he followed her to her office. She was a beautiful woman, and all this talk of privacy and impropriety was making his imagination run wild, but he convinced himself it was just his hormones talking.
They sat down in her office. "Sid, you're an excellent student, and if I may, you're a very handsome young man, and you're my first choice for someone to help me with something I need to take care of."
Sid had been frozen in his seat since she called him "handsome."
Ms. Kane gave him a knowing smile, and continued. "Just for this weekend, I want to swap bodies with you." Sid was having trouble processing what she'd just said, but she continued on. "I've acquired a certain artifact that is capable of this. It can swap our bodies for 48 hours, after which we'll automatically return to our current forms. You see, I have some private business I need to take care of, and I'd like to use your body to do it. In return, you can do whatever you want with my body as long as your in it. I promise you, this has certain...advantages." She purposefully undid the top few buttons of her blouse and spread them apart to reveal substantial cleavage. Then she looked at him, waiting for a response.
Sid eventually stopped gaping. "You want to... switch bodies? What are you even talking about?"
"It's exactly as simple as I've stated. 48 hours, no more, no less." She glanced at the clock. "It's 4:30 on Friday right now, so Sunday afternoon we'll switch back. It isn't strictly necessary, but let's try to meet back here for the switch. I've cleared my schedule for the weekend, so you'll have no responsibilities. Just you, my body, and it's accompanying hormonal urges. What do you say?"
Sid was in disbelief. But somewhere between the hormones telling him to say yes to this attractive woman, the sheer novelty of the experience she was proposing, his disbelief that any of this was real, and the simple curiosity about what game she playing, he agreed. "I'll do it."
Ms. Kane smiled. "Excellent." She opened a drawer in her desk and removed a simple looking box. She opened it and removed a stone tablet the size of a textbook. It was covered in intricate carvings of what appeared to be both Nordic runes as well as Mayan hieroglyphics. To the naked eye, it gave all appearances of being genuinely ancient. Where could this have possibly come from, Sid wondered.
"Place your finger here." She said, gesturing to a ringed circle at one end of the table. He did so, and she placed her finger on a mirroring circle on the other end. The carved symbols began to grow a bright blue light, then they flashed, filling the room with light. Sid opened his eyes, and saw his own smiling face looking at him. His body clapped his hands. "Excellent! Thank you so much, I won't forget this."
He stood to get up, while Sid still sat in shock that it had actually happened. He watched his body head for the door, and before it left it turned and said "See you in two days. And be sure to have fun... Susan." Then he was gone.
Sid looked down at Ms. Kane's... Susan's.... his... cleavage. He began rubbing the soft mounds. Another hand shot to his crotch, and found it smooth and flat. He lifted up the skirt he was wearing and saw pink the pink panties he was now wearing.
"OH MY FUCKING GOD. She was telling the truth!"
Sid paced about the room, alternative feeling up his new residence and trying to figure out what to do. He gathered his thoughts, and decided to leave. He picked up Ms. Kane's purse and left the building.
As the temporary Ms. Susan Kane walked around outside, she noticed the sway of his hips, the breeze through her skirt, and the glances she was receiving from men all around her. "I guess I'll go home..." she thought. "But to where? I don't know where Ms. Kane lives. What the fuck was I thinking, agreeing to this?" Then she got an idea. "I could go back to my dorm room. Matt is probably there, and I could probably tease him with this body." Sid found that idea strangely appealing.
She returned to his dorm, where the door was open, as usual, and sure enough, Matt was there, hunched over his desk checking Facebook on his computer. Sid leaned against the open doorway and waited for Matt to notice. Matt had mentioned before how hot Sid's teacher was, not that many guys would disagree, so Sid knew this would be fun. Matt looked up to see who was there, and when he saw Ms. Kane, he sat up straight and pivoted his chair towards her in surprise.
Sid them got a good look at Matt head on. He was wearing one of his smaller t-shirts, and she could see the tight shoulder muscles and pecs beneath it. Sid's breath quickened in her female chest, and she felt a stirring that took her by surprise.
"Uhh. Mrs. Krane! Wh-what are you doing here?"
"It's Kane. Ms. Kane. But you can call me Susan" Sid was proud of how smooth that line came out.
Matt pulled himself together and calmed his nerves. He stood up and gestured to her to come in.
As Matt stood, Sid, gazed upon his chest, topped with broad, powerful shoulders, tapering down to a straight, firm, waist. She finally looked up, realizing that Matt was towering above him now, and from this angle, she could really see what a strong jaw Matt really had. He had a scruffy five o'clock shadow, and Sid's heart quickened again. She felt a tingle on her chest, and glanced down to see that her nipples had hardened. She quickly looked back at Matt, who was trying to play it cool.
"Uh, what can I do for you, Ms....Susan?"
Sid managed to fumble out the line he'd planned earlier. "I needed to talk to Sid, but now that I see that you're here, maybe not" She blushed heavily. Why did she think that was a good thing to say? She was flush with embarrassment. Had she blown her chances? Wait, what?
Matt had an awkward expression of confusion and arousal. "Uh, I think Sid should be back soon, unless he went out after class. What were you saying about...uh, me?"
Sid was very surprised by the feeling in her body right now, especially the moistening in her panties. Her legs bowed a little. "Uh, what I mean is..." she tried to say. Her vision noticed a subtle movement twitching, and she scanned to see that Matt had a raging boner that he seemed to be preoccupied with hiding. She could feel her heart beating in her chest.
"What I need is..." She heard the door click shut behind her. She didn't know when she'd maneuvered it behind her, but her involuntary thrust of her hips had finally shut it.
"What I need is.... a man."
Matt stepped forward in a trance, and ripped open her blouse. The shock and arousal of it made Sid think that she was going to cum right then and there. One of Matt's hands rubbed her breast, and the other wormed it's way under her blouse to unhook the black bra she was wearing. It fell to the floor, then she grabbed Matt's shirt and pulled it over his head. He worked it the rest of the way off while she caressed every supple muscle on his torso. She reached around him, feeling the muscles tensing on his back, and pulled him down to kiss her. Soon she was on the bed, and Matt was fumbling to take his pants off. When he was done, she reached into his boxers and grabbed his erect penis, and she felt her arms and legs turn to jelly. She needed that dick. She tore down his underwear and began sucking on it vigorously. Her right hand was helping the shaft while her left hand was pulling down her sopping panties and began fingering her clit. She didn't let Matt cum, though. She pulled her skirt and panties off completely, then laid back on the bed. Matt quickly followed and penetrated her moist pussy with his hard member.
Sid felt waves of pleasure rocketing through her body as Matt began thrusting harder and harder, faster and faster.
Sid awoke from a stupor some time later. She felt her roommate's sleeping body cradling her from behind, hand on her breast, semi-erect cock pressing noticeably on her rear end.
She still felt the warmth dripping from her vagina.
"Hmmm, 48 hours, you say?"
