The morning after I fucked Rachael at a concert, I found myself pacing anxiously around my kitchen. I was nervous about popping the question rattling around my skull, but I couldn't deny the emotional momentum Rachael and Emily had brought to my life, nor could I minimize my desire to maintain it. I knew Rachael was at least halfway on board, since the original idea had been hers, but if Emily was against the proposal and Rachael was all for it, that could be devastating to the happy home we'd begun to build.
The matching satisfied grins on their faces as they arrived for breakfast made it easier. I decided to preface the question in the horniest way possible, to pique Emily's interest. "Emily, how would you like to tie Rachael up and turn her into a cream pie factory for a few weeks?" Rachael's eyebrows shot up her face. That plan had been how she suggested this end goal, but we hadn't discussed it since they'd moved in with me.
"Ohhh, that sounds like fun." She turned to shoot a smoky look at Rachael before facing me again. "I do like it when we fuck with a theme."
"Well," I continued, "the theme here is the purpose, not the process."
Rachael cupped Emily's chin gently and turned the red head's eyes to her own. "I want us to have a baby, all three of us."
Emily froze for a long moment before she smashed her mouth onto Rachael's and immediately shoved her tongue down her girlfriend's throat. They were both whimpering when she tore apart their kiss with a loud, "mwha!" which she followed with, "Holy fuck, I think I just found something hotter than being fucked on a table."
I pulled them both to their feet and squeezed them tightly, Emily's vanilla perfume and Rachael's sandalwood hair mingling in my nose. "I want you both to understand that this isn't just about kinks. I want to build a life with the two of you. Instead of you living in my house, I want this to be our home. I want my bedroom to be our bedroom, and I want your bedroom to be a nursery." I kissed the tears from their cheeks as they stared up at me. "Plus, this means Emily will stick around for a while and I can justify putting in a pool for skinny dipping."
Emily sprouted a huge grin. "So, who gets knocked up first? Oh oh, are we gonna get preggers at the same time and make him service us and play with each other's mom tits all day?"
"Hell no," I interjected. "One pregnancy and one infant at a time. Mommy gets pampered for a few years, then we can switch, if we decide that's what we want."
"Probably a good idea," Emily replied. "If we both get pregnancy horny at the same time your dick might fall off."
I shoved Emily against the wall and fondled her tits roughly through her shirt, which was paper thin and impossibly soft, like only something old and well-worn can be. Something about the way it barely concealed and protected her was particularly enticing - like the thong equivalent of a shirt. I was lost in a memory for a moment, the memory of her buying that shirt and eye fucking her at a concert more than a decade earlier. "You know this means you get little to no dick until we have a positive test, right? This was Rachael's idea, so she gets to go first. We'll still take care of you, but every load goes into her. It's your job to keep us both crazed until we knock her up. I promise we'll take turns demolishing you once we get there." I turned to look at Rachael. "And you only get toys in your ass until then."
"It's a sacrifice I'm willing to make," Rachael said with a faux pout.
"I'm in," Emily replied. "When can we start?"
Rachael pulled her thin shirt off her voluptuous body, the only thing she wore, sat on the edge of the table facing Emily, and spread her legs wide. "As soon as you get us ready." I pushed Emily toward her. She grabbed Emily's flaming red hair and pulled her face between her thighs. We passed Emily back and forth, making her pleasure both of us with her mouth until she tried to drag my dick into Rachael's waiting pussy.
"Breed me like the horny slut who wants to be kept forever that I am," Rachael demanded as I slid into her. She was wetter than I ever remembered, more so than at the concert, more than the first time we played a rape game. "Fuck me. Put a baby in me so you know how much I love you. Own me forever," Rachael begged me while I filled her. Normally, Emily would have inserted herself into our coupling in some way. Instead, she stood to the side and watched, rapt and wide-eyed, amazed at the blissful ramblings gushing from Rachael. I clutched our mom-to-be tightly to me as I drove deeply into her. Our locked eyes held nothing but needy affection. We climaxed together ferociously, knowing that her getting pregnant was unlikely right then but inevitable all the same.
Emily was feverishly kissing both of us as soon as we caught our breath. Rachael pulled Emily's pussy to her mouth while I kissed and fondled our red-headed girlfriend until she soaked Rachael's face with a howling orgasm. After breakfast, we spent the day naked, constantly teasing each other. Any time they managed to get me fully hard, Emily would immediately start chanting, "Baby! Baby! Baby!" while she and Rachael fondled each other and Rachael gave me her best fuck me eyes. I quickly started to hope she had trouble conceiving.
I cheered when she started menstruating a week later. She looked hurt, until I explained to her that I was having too much fun trying to knock her up to stop after just a week. "You need to take some vacation time," Emily provided.
"She's right," I confirmed. "You wanted to be my breeding captive. Captives don't get to leave the house or put on clothes. Once your period is done, we're gonna fix that."
"Why don't you just quit?" Emily prompted. "We make plenty of money. You can be our sex slave and breeding stock that we use whenever we want. You won't have to deal with that job while you're pregnant, since I know it's just something you do, not something you love." She kissed Rachael softly. "Oh oh oh! And you'll always be right where we want you once he knocks you up so we can take adorable time lapse pics of your belly getting big! Plus plenty of hot preggo porn!"
Rachael looked at me with tears in her eyes, and I nodded. She leapt to me and squeezed me tightly before whispering in my ear, "I think she needs DPed on the table for her excellent suggestion."
I slapped Rachael on the ass hard enough to make her gasp before I told her, "Go get dressed." Emily turned to watch her leave with confusion on her face, which gave me a window to throw her face down onto the table and yank off her thong; she rarely wore more than that at home, under the transparent guise of keeping Rachael and I turned on for baby making purposes. She groaned loudly when my tongue went straight for her backdoor. Rachael returned with their strap on snugly attached and immediately stuck it in Emily's face. "You look so sexy with that dick in your mouth," Rachael told her - a common refrain traded between the two of them when one was sucking my cock, originating from the first threesome we had. I buried myself in Emily's ass, and we did our best to saw her in half. She was writhing with frustration at her inability to come by the time Rachael pulled her plastic cock from between Emily's lips.
Wordlessly, I scooped up Emily, carried her to the living room couch, and laid on my back without ever removing my cock from her ass. Rachael immediately climbed on top of her and slammed her strap on dick into Emily's dripping pussy. We spent hours making up for the limited fucking she gotten recently. She was too worn out to scream through her last orgasm when I exploded in her.
As promised, as soon as Rachael's period ended, we tied her to my bed and teased her for hours. Emily brought me dangerously close to coming several times with my dick in Rachael's face before I finally fucked a huge load into her. Emily took over and made me watch while she teased Rachael more and forced our mommy-to-be to pleasure her repeatedly until I was hard again and so turned on I shoved Emily out of the way and fucked a dozen orgasms into Rachael before giving her a second chance at pregnancy.
