Our first MFF for our birthday

My friend Dima and I have been friends for years, and it was his birthday—he was 22. So, naturally, I came. Of course, how could he not? He was renting an apartment with his girlfriend, Lera. She's so beautiful, slim, with a round butt, neat B-cup breasts, dark shoulder-length hair, and brown eyes. Basically, even the first time I saw her, I thought Dima was lucky. So, when I showed up, almost all the guests had already left, leaving just me, Dima, and Lera. His roommate, Artyom, was there, too, but he'd left somewhere earlier, so it was just the three of us. We were sitting in the kitchen, drinking beer, laughing at all sorts of bullshit, reminiscing about school and partying. Lera had already had a fair amount to drink, her face flushed, her eyes shining, and she kept looking at me strangely. At first, I didn't pay attention—well, who knows, she'd been drinking. But then she started clinging to me when we went into the room, like they wanted to continue. Dima seemed fine, didn't react, even smiled a little. We sat down on the couch, Lera between us. And then she says, "You know, I've always dreamed of having two guys at once." I was completely stunned. Dima laughed and said, "Seryoga, what about you?" Well, I said, "I don't mind, if you don't mind." Lera beamed. Dima said, "Well, since it's my birthday, the gift will be just right." And then it began. Dima started kissing her first, and I watched at first, then joined in too. We undressed her together, and she didn't resist, on the contrary, she helped, pulled off her T-shirt, and unbuttoned her bra herself. Her breasts were truly amazing, her nipples sticking out like studs. Dima grabbed her breasts, and I started kissing her neck, and she moaned softly. Then we laid her down on the couch, and Dima was the first to penetrate her. He has a normal dick, about 18 centimeters. He started fucking her, and at the same time, I put it in her mouth. Lera sucked well, tried hard, worked her tongue, and I almost came right away. We switched several times. Sometimes it was me in her pussy, Dima in her mouth, sometimes vice versa. Lera moaned, squirmed, and said, "More, more." Dima came in her mouth for the first time, she winced and spat it all out. Then I came on her breasts, and she smeared all the cum over her nipples. Dima said, "You're amazing, Lera." She laughed and said, "I told you I wanted to try a threesome." Then Dima suggested trying it in the ass. Lera hesitated at first, but then agreed. Dima brought oil from the kitchen, smeared it on her ass and his cock, and slowly entered. Lera whined, of course, but then relaxed and began to move. I stood nearby while she sucked my cock. We fucked her like this for about twenty minutes. Dima came in her ass, pulled out, and I immediately inserted it into her pussy. She was all wet and hot, I entered easily and began to fuck her hard. Dima sat nearby, watched and languidly jerked off. Then he became aroused again, came over and inserted it into her mouth. We fucked her again together, I came in her pussy, and Dima couldn't cum anymore. Then Lera went to take a shower, and Dima and I stayed on the couch, catching our breath. Dima says, "So, are you okay?" I say, "Awesome." He laughed, "Best birthday ever." Lera came out of the shower, all clean, in a robe. We took turns washing ourselves, too. Then they both lay down on the bed, and I settled down on the couch. And Dima and I were lying there, laughing quietly so as not to wake her. He says, "Seryoga, you gave me the best present, thanks for coming." I say, "Come on, thank you for inviting me." This is what my friend's birthday was like.
