I'd been dating Amy for about five weeks, and had progressed from dating weekly to dating twice per weekend to dates almost every night. She was 26 years old to my 28, 5'5", a long-haired blonde with an athletic build. We had met at a dance club, and after dancing together for two hours, she gave me a phone number that didn't turn out to be bogus, and she accepted when I called and asked her out to dinner for the following weekend.
But we still hadn't slept together. Usually, it only took me 5 or six dates to get a girl in bed, but Amy and I were up to 12 dates, and I still hadn't gotten past second base with her. We'd go out, have a great date, whether dinner or dancing or a movie, laughed our asses off most of the time and would spend at least an hour making out in my car in front of her apartment building, before she said good night and got out of the car. And I'll tell you, it was a damn glorious set of tatas to play with, C cups with thick nipples, and I could tell she was having little orgasms from the stimulation, but she'd slap my hand if it strayed further south and say "Not yet.". But it never felt like she was being a cock-tease, even though my balls ached after a couple of those nights and I had to masturbate to get to sleep.
It was more like she was waiting for something, something to give her permission to go further. I didn't know what it was, but I was willing to find out. I was already falling in love, and there was no way I was going to screw that up by being too demanding with her. I'd actually even browsed a couple of jewelry stores, because I knew she had a birthday coming up. Not an engagement ring, not yet, but I thought a necklace or some nice earrings would be a nice step in that direction.
It was a Tuesday, and she texted me that she wanted to meet after work at the food court at the mall closest to my office, and we'd see what movies were playing, and either see one, or decide where else to go. At the end of the text, she said "Love ya!". We hadn't said those words face to face yet, so I wondered if Amy had found her permission. I sure hoped so, my dick needed some relief.
I got done with my programming work around 6, and sent Amy a quick text saying I was on my way. The mall was only 10 minutes from my work, but I'd been expecting to be done around 5:30. But when you're debugging code, sometimes you have to finish a problem or you'll be thinking about it all night.
Anyways, I parked my car, and entered the mall. It only took me five seconds to spot her, over by the Chinese place. She was wearing a blue blouse that I'd seen her in before, and I walked over, leaned my head down, lifted her chin and gave her a 10-second french kiss.
"Ahem," I heard from my right. I turned my eyes, and saw Amy looking at me with an amused expression, wearing a red blouse over the same style jeans. "What the hell?" I thought. I broke the lip lock I was in the middle of, and looked down... at Amy. Or at least I thought so. My heart skipped a beat, and It took two seconds for the light bulb to turn on, then explode. "Oh, my gawd, you have a twin?"
"Smart boy, Josh," Amy-in-red said. "So you want to give your girlfriend at least as good a greeting as you just gave my sister Kate?" I leaned over to her in the same way, and did my best to top the first kiss. I stopped when the first moan came from Amy's throat. We were in a public place, and I could tell that everyone, and I mean everyone, was staring at us by that point.
I sat down on the opposite side of the table from the two girls, and looked back and forth at them for 20 seconds, looking for some difference between their faces. No freckles, no scars, their hair was the same length and styled the same way. I realized that I was in shock, and finally spoke. "I'm so sorry, Kate. You two look exactly alike. I can't see a single difference."
Amy chuckled. "Most people can't. Our parents actually had to give us different styled earrings as babies so they could tell us apart, and we sometimes joke with them that they got us mixed up before doing that, so I might actually be Kate, and she's Amy."
Kate reached her hand and touched mine, and said, "You don't need to apologize, Josh, that kiss was worth the little bit of embarrassment. You kiss really good."
We chatted for half an hour, talking about their childhoods, our respective jobs (Kate as an admin assistant at a marketing firm here in Boston, Amy as a manager at one of the suburban Macy's, me as a programmer for an insurance company), when I asked the question that would seal my fate for ever more, "So, I've heard about identical twins sometimes taking each other's place on dates with their boyfriends. You two ever do that?"
They looked at each other for a second, then took each other's hand, and in unison, said "Always."
My head spun, my vision dimmed a little, as I looked at them both. "So... you mean...oh gosh... I've been dating you both?"
Nodding their heads up and down rapidly, they said in one voice "Yuuuup!"
Amy (or at least I thought it was her, now I wasn't so sure) started, "Josh, we've actually done this...
(Kate) "...since we were 16."
(Amy) "Whenever a guy would ask one of us out for a second date..."
(Kate) "...we'd swap..."
(Amy) "... and see if he could tell."
(Kate) "Except nobody..."
(Amy) "...ever did..."
(Kate) "... even the guys who knew..."
(Amy) "... we were twins."
I had to push my mouth closed. "Oh my gawd, you two finish each other's sentences, too?"
(Unison) "Don't all identical twins?" They laughed.
"So... what happened after the second date?"
(Amy) "Sometimes we'd both decide..."
(Kate) "...not to take it further.."
(Amy) "...or we'd decide to keep going to..."
(Kate) "..see who liked him better."
"And if that wasn't the one he thought he was dating?" I asked.
Amy chuckled. "You'd be amazed at how well 'I think my sister really likes you' would work during a breakup, to get him to ask the other one of us out."
(Kate) "Either way, we'd be exclusive..."
(Amy) "...with the guy after that, for however long it lasted."
Kate blushed before saying, "We actually both lost our virginities to this boy named Brad that way, after we turned 18. I let him fuck me on one of my dates with him, but then broke up with him over some argument the next day but let him know Amy thought he was hot, and three dates with him later, she went to bed with him too..."
(Amy) "...then Mom found out what we were doing, and she read us the riot act for a couple of days. She didn't actually tell us we had to stop switch-dating, but..."
(Kate) "...she made us promise her two things - that we'd never sleep with a guy when we were both still secretly dating him..."
I immediately knew why I was stuck at second base, with not one but two girls. Thanks, mom.
(Amy) "...and to never intentionally hurt him or each other by being jealous."
"And did you ever tell any of the guys you were both dating him?"
(Unison) "You're the first."
"Why tell me, and are you going to tell me which of you likes me better?"
(Amy) "Why are we telling you?"
(Kate) "Because we can't choose. You're the first guy we've switch-dated this many times..."
(Amy) "...and we both think we're falling in love with you.."
(Kate) "...which has never happened before."
(Amy) "We decided we needed to tell you..."
