Natalie and I started dating our freshman year of college. By the following year, we both just knew that we'd end up spending the rest of our lives together. So I didn't think much of it when we ran into her ex-boyfriend Mark on campus one day, even when she ran up to him and threw her arms around him in greeting.
"Mark! How have you been?"
It took him a moment to recognize her. "Hey, Natalie! You look good!"
"Thanks. Um, this is Kyle."
We shook hands. Soon the three of us headed to a nearby restaurant to get caught up. They'd dated in high school and broke up not long after they graduated. He'd spent a couple of years at a community college back home, then transferred to our school. He wasn't chasing after her; he'd wanted to go to this school since before he started dating her, and they'd both had a couple of years to move on.
That little meeting could have blown up in all of our faces. But it didn't. She didn't ignore me, she told him about her life with me, she told me some stories about her time with him, and he and I compared notes directly. Mark and I found that we clicked, and from that day on we were friends.
Over the next several months, the three of us all hung out together regularly. Sometimes Mark and I hung out without Natalie. Mark dated a few girls here and there, but never got serious with any of them.
One day his plans to meet up with us fell through. She seemed really disappointed, and I started wondering if there was something more between them. We went out without him, and she mostly got over it before we came back home, but I still wondered exactly how she felt about him. I couldn't think of a good way to ask her without it sounding like an accusation, so I let it go.
Her birthday came up not long afterward. Mark's roommate was out of town that weekend, so he volunteered to host a birthday party for her. He got the drinks (he was the only one of the three of us that was over 21 at the time), I got some food and some cake mix, and we invited Natalie and a few of her friends.
Natalie is a little bit shorter that Mark and I. She's slim and just curvy enough to be nice and snuggly. Her cute little breasts are small enough that she sometimes doesn't bother to wear a bra under her T-shirt, and her birthday party was one of those times.
About halfway through the party, I hit the restroom. On coming back out, I heard voices coming from Mark's bedroom. I have really good hearing, so I didn't need to press my ear to the door or do anything else to give myself away. Mark and Natalie were in there talking about what CD's in his music collection they should bring out to play next. Then they got quiet for a little while.
Then Natalie said in a worried, almost despairing voice, "Please stop looking at me like that. Kyle's been good to me, I can't do that to him!"
"You're right. He's my friend and I'd be a shitty friend if anything ever happened between us."
"Yeah, and I'd be a shitty girlfriend."
They went quiet again, then Natalie said, "OK we need to get out of here right now before we end up in that bed. I'm going first, wait before you follow me."
That was my cue to head back to the living room. I placed myself as casually as I could next to the opening of the hallway and listened for the door opening. The seconds ticked away and the door remained ominously closed. I found myself getting turned on at what might be happening. Right when I'd concluded that she had been unable to pull herself away from the temptation, that door finally opened.
Natalie came out of the hallway and saw me. I kissed her. She returned the kiss with feeling, which reassured me. I didn't taste anything on her lips or tongue other than her saliva. I had no idea if I would be able to taste anything if it was there, but at least I didn't find any sign of anything untoward happening. She broke the kiss quickly, since her friends were around and prolonged PDA was considered rude.
It seems that she had remained faithful, but only by the hardest. There was no longer any doubt that there were still feelings between them. The way I figured it, she'd have to either continue resisting temptation every time they happened to be alone together, break contact with him completely, or break up with me and start dating him (in which case I'd have to break contact with her for my own sanity).
This had to be a very difficult position for her to be in. She was probably wishing that she could somehow have both of us.
Wait, why couldn't she have both of us? When I thought she was kissing Mark, I had not the slightest desire to break up with her over it. The only worry I had was that she'd decide to break up with me so she could be with him If she knew she was allowed to be with both of us, I figured there would be no reason in the world for her to break up with me.
I was surprised to find that the thought of Mark and I taking turns with Natalie in bed was getting me really excited.
Now the question was how to bring this up. Right now neither of them even knew that I knew how hard it had been for them to behave. Do I start by talking to Mark or by talking to Natalie? Or do I wait until I can bring it up with both of them at once? How would Mark react? Would he be willing to share Natalie with me? If not, at least it would all be out in the open.
I kept turning it over and over in my mind while trying to keep participating in the party. I swapped CD's when needed, put more food out, and kept busy so my brooding wouldn't become obvious or spoil the party. Mark and Natalie kept looking at each other, getting close to each other while making sure not to actually touch.
Finally, everyone except for Mark, Natalie, and I had left. Natalie said, "Thanks, guys, that was a fun party!"
"Yes it was. We should stay and help Mark clean up."
I had decided to bring it up after we cleaned, but still wasn't sure how to start. After we cleaned the three of us just kind of looked at each other. I finally spoke up.
"I think it's time for us to give Natalie her birthday kisses. You go first, Mark."
They looked at me quizzically. I didn't say anything else. Finally, they looked at each other and softly pressed their lips together for a split second. Then they looked at me.
I said, "Come on, guys, you can do better than that." I surprised myself by successfully getting those words out, and I certainly surprised them. Natalie giggled nervously, and we all looked at each other a bit awkwardly.
Finally they both shrugged as a gesture meaning, "Okay, if you say so," and leaned toward each other for a kiss. They gave each other another peck on the lips, then he pushed his tongue against her lips. After less than a second of hesitation, she parted her lips and slipped her arms around him. Their kiss quickly became a hot, sensuous makeout session, with their arms around each other and their tongues dancing in each others' mouths.
I watched them for about half a minute, then came up behind her and started kissing the side of her neck. She tilted her head to give me more access. I kept that up for about a minute while they made out. Then I softly said, "My turn" and turned her around to face me.
Mark didn't let go of her, simply let her turn around in his arms. He ended up holding her from behind with his hands just above the waistline of her shorts. I leaned in for a kiss and started my own hot makeout session with her. This time I could slightly taste a new flavor on her lips and tongue, convincing me that they had not kissed earlier in Mark's room.
I kissed her for a few minutes, switching from a steady makeout session to a series of quick but sensuous kisses, then back to making out. She tilted her head to allow Mark to kiss the side of her neck at the same time. Then I decided on my next move, one that would convey to her that I wanted more to happen and gauge whether she wanted it as well. I knew that in her place I would definitely want it to happen, but she had never mentioned threesomes at all and may or may not want one tonight.
I pulled her shirt up, untucking it from her shorts and bringing the bottom of her shirt above Mark's hands. She tensed up. I let go of the shirt, letting it fall and cover his hands and leaving them directly touching her bare belly. He left his hands still, I started kissing her again, and she soon relaxed.
He pulled her backwards a bit against him. She pulled me with her so that I was slightly pressing against her from the front. I could feel his hands through her shirt, so I knew when he started stroking her belly. He started with short strokes and kept that up for a while. He gradually got his hands to go higher with each stroke. I could feel her body start to get warmer.
Natalie let go of my waist and rested her arms on my shoulders. This allowed him to raise his arms and hands as high as he wanted without her arms being in the way. It didn't take him long to take advantage of it. He slid his hands down to the top of her shorts, then slid them back up and kept going. She took a sharp breath when his hands both reached her breasts. I could feel the change in his hands as he gently squeezed both breasts. She took another sharp breath and moaned a bit; from that and the movement I could feel through both of our shirts, I correctly inferred that he had started pinching her right nipple. She kissed me harder than ever.
She turned her head and kissed him. I could now look down and see the outline of his hands through her shirt. I kissed the side of her neck again and listened to her soft moans muffled by their kiss. I turned her head back toward me and kissed her again. Then I pulled her shirt up.
