You should do it

“Do it,” the professor cut me off.

“What?” I asked, not so much because I didn’t hear her as because I was startled by her sudden decision.

“Go ahead,” she reiterated. “See if she’ll take you in.”

Since she was being a bit vague about the specifics, I hesitated before asking, “You mean … what she says here about…?”

“Yes,” the professor said shortly.

“O … kay,” I said slowly. “It’s just … I want to make sure, because you sound a little … I don’t know … conflicted?”

“No, I’m fine,” she said brusquely.

I sat silently for a moment, trying to decide what the best way to say “I don’t believe you” would be without offending her. “Look, professor…” I started.

“No, really, it’s fine,” she cut me off. I heard her sigh, the sound a bit odd. I realized after a moment that it was because she must have pulled the mic away from her mouth for a moment, or covered it with her hand. “Okay, here’s the thing,” she said finally. “I guess there’s no reason not to just say it. It’s not like I’ll ever have to face you,” she said wryly. “If there was ever a person I could be sure I’ll never have to talk with face-to-face about something embarrassing, it’s you.”

“I guess so,” I said with some amusement.

“So the thing is … it turns me on,” she admitted.

“It…?”

“Yes,” she said brusquely. “The idea that you’ll go and … have sex with this … this … with my doppelganger. That I’m going to be able to watch you having sex with ‘me’ through your own eyes … it turns me on. I guess … I guess you could say I’ve never had much of a sex life. Well, to be completely honest: I’ve had a grand total of three sexual partners, and I was only intimate with two of those more than once. But it’s not that I’m any less … less…”

“Horny?” I suggested.

“Yes,” she said flatly. “Horny. I’m not any less horny than anybody. I’ve just never been a very social person. The idea of having a vicarious sexual experience through this alternate version of me—a ‘me’ who has casual sex with her roommates and advertises for threesomes on the Internet … a ‘me’ who isn’t afraid to admit her interest in women—it’s exciting.”

“Okay, I guess I can understand that,” I said. “But to be honest, I’m a little worried,” I added.

“Worried? Why?” she asked.

“Well … frankly, the idea of having a sexual relationship with your twin—especially one who’s interested in having wild threesomes, like you said—is pretty appealing to me, too. If you’re going to be honest, I might as well, too: I think you’re very attractive.”

“Uh … thank you,” the professor said tentatively. I could practically hear her blushing through the comm-link.

“But here’s the thing: what if things don’t go so well between your double and me?” I asked. “Sexual relationships don’t always work out, especially between strangers,” I pointed out realistically. “Or what if you find the experience of watching it through my eyes more uncomfortable than you think? Or what if everything turns out fine, but you just feel more embarrassed about talking to me afterwards than you think you will? You’re my only lifeline to where I came from, and who I really am. I don’t want to end up with dead air on the other end of this mic for the rest of my life because of an awkward sexual episode,” I explained.

“Well, I can understand that,” she accepted, “but I think I can stay objective even if things go bad,” she declared.

“You say that now…” I said dubiously.

“No, really,” she insisted. “I’d like to think that even if I get a little uncomfortable, I’d be able to remain objective enough not to just abandon you. I think I can promise that no matter what happens, I’ll be staying in regular contact with you.”

I realized that between her earlier insistence on believing that her double would be understanding of my plight, and her present insistence that no amount of embarrassment would drive her away from radio contact with me, Professor Rosenblum had a strongly idealized self-image. I hoped she would live up to it.

“Okay, professor,” I said. “If you’re sure, then I’m willing to give it a shot. I mean, who knows? Maybe I’m not even her type?”

“Sure you are,” she said, then fell silent. Again, I could almost hear her blushing in the sudden silence.

For my part, I was grinning. “So, Professor?” I asked glibly. “Do you think if I had stayed in our world, we could have been lovers ourselves?”

She was silent for a minute or so. “Well, I … I don’t … I’d like to think that…”

“Oh, come on, Professor,” I prodded. “No sense being embarrassed with the guy you’ll never see again, remember?”

“Well, yes,” she acknowledged. “I suppose … I do find you attractive. And I … well, like I said…”

Since she apparently had trouble saying it, I supplied: “You’re horny?”

“Yes,” she accepted frostily. “I’m horny. So, yes … I suppose … if you would have…”

“Well, I’ll admit, your first impression did leave something to be desired,” I kidded her gently, “but if you’d asked … definitely.”

“You … you wouldn’t have minded that I’m … a little older?” she asked tentatively.

“Are you kidding?” I asked. “You look great, whatever our ages. And not to be crass, but with a figure like yours, I doubt there are many guys who wouldn’t be interested in you even if they wouldn’t usually go for older women.” The professor was slim—unusually slim for a woman near forty, I’d say—but she also had usually large breasts, although she’d been dressed modestly enough when we had met that it hadn’t drawn my attention too distractingly. “If ideas about your age are what’s stopping you from getting yourself out there in our world, I’d reconsider,” I advised her.

“Well, I … I, um…” the professor sounded a little startled.

“Tell you what, Professor,” I said. “Think about this for a second: I’m about to go see if your exact double wants to have sex with me—no, not just have sex with me; wants me to move in so we can have sex all the time. Does that sound like something I’d do if I wasn’t attracted to you?”

“Well, I…”

“In fact…” I continued, “when you think about it, your double here may not really look exactly like you,” I pointed out. “I’m assuming I’ll want to move in with her based on what I know you look like. So if you think about it, what I’m really saying is I’d like to move in with you, and fuck you all the time,” I said as salaciously as possible.

“Oh … oh, my,” the professor murmured.

“Professor?”

“Y–yes?” she stammered.

“You mentioned that you were moving your comm equipment. Where are you now?” I asked.

“At home,” she said. “I thought it would be—”

“Take your clothes off,” I interrupted her.

“W–what?” she stammered.

“I want you naked,” I said, and heard her audibly gulp on the other end of the line. “Take your clothes off, Professor.”

“O–okay,” she said.

I heard a muffled clatter as the headset she was using to talk to me was put down, then some even fainter shuffling sounds as she got undressed. While she was distracted, I quickly stood up from my chair in the library’s computer room, which I had noted was in a more or less secluded part of the building—currently deserted except for me, in fact. I, too, took off all my clothes, carefully keeping my eyes on the rest of the room, not looking down at myself or what I was doing, so the professor wouldn’t be able to see that I was undressing through my eyes if she happened to look at her display.

Once I was naked, I sat back down, still carefully keeping my eyes on the computer monitor. It felt extremely strange to be naked in public—nervous and exciting, even though I knew that in this universe, nobody would bat an eye to see me sitting here this way even if somebody did happen to walk into this part of the library.

After a moment, I heard the headset being picked up again.

“H–hello?” she stammered.

“Professor, are you naked now?” I asked.

“Y–yes,” she confirmed nervously.

I looked down, and hefted my dick in my right hand. It was already semi-turgid from all the erotic talk and from the novel thrill of being naked in a public place, albeit I was not yet fully hard.

“Ohmy!” the professor blurted when her view of my vision took in my naked abdomen and crotch.

“Professor, there’s something special I can do with my dick. I’m going to do it now, so you can watch,” I told her, starting to stroke me dick.

I heard her start to breathe heavily.

“I want you to masturbate while you watch me, Professor,” I told her. “Professor?” I asked after a moment. “Are you playing with yourself yet?”

“Y–yes,” she mumbled with some embarrassment. “I … I was already. When I saw you … your…”

“Okay, good,” I said to spare her the ongoing embarrassment of bringing herself to say it, feeling both pleased and a bit amused at her initiative. “Can you guess what I can do with my dick, Professor?” I asked. I didn’t wait more than a couple of seconds for her to reply, though. “I can suck it.”

I heard her gasp a little over the mic.

“That’s right. I can suck my own dick. And I’m going to do it now. I’m going to keep my eyes open. And can you guess what I want you to imagine while you watch?” I asked.

“That … that it’s me sucking it,” she said in a small voice.

“That’s right,” I told her. “Now, professor … are you ready?” I asked.

“Oh my god,” was all she said.

I used one hand to aim my prick upwards—by now fully erect, thanks to my stroking and the dirty-talking—and bent over sharply in the chair. My dick was about nine and a half inches long when I was completely hard—it was maybe nine right now, not being totally stiff just yet—and I was flexible enough that when I really pushed it, I could get maybe an inch or two into my mouth. Not a whole lot, really, compared to getting a blowjob from another person, but definitely better than just jerking off.

“Oh my god!” the professor moaned again once she saw me starting to suck my dick, through my own eyes. After a few minutes, I started hearing rather noisy squelching sounds on the mic. Evidently, Professor Rosenblum was working up quite a storm of her own between her legs while she watched me.

I took my time. I wasn’t too worried about anyone coming in and catching me. In the first place because I’d been in the library for hours and hadn’t seen anybody else in the computer room, and in the second because I was pretty sure no one who came in would even care if they did catch me, in this world. All in all, I think I sucked my cock for about fifteen minutes, periodically taking short breaks to rest my over-bent back while I simply jerked off. Meanwhile, I had heard the professor have no less than three orgasms of her own. She seemed to have a particularly easy-to-hit trigger, and each successive orgasm came sooner than the last.

When I finally felt like I couldn’t hold back any longer, I stopped sucking my dick and pulled back a bit, far enough that the professor would be able to see me cumming through my eyes on her display. It would be a whole lot messier than just finishing in my mouth, but she wouldn’t even notice that if I did, and this was really all for her benefit.

“Here it comes, Professor,” I said, my voice tight as the orgasm washed over me, tightening the muscles of my body and constricting my diaphragm.

I began to cum, spurting jism all over my belly and chest, not to mention getting my hand and dick absolutely sloppy with the stuff as I continued to jerk off.

“Oh my god!” the professor fairly shouted into my ear, then continued to pant and cry out as she, too, had an orgasm of her own.

“Wow. Cybersex?” another voice asked.
