Ever since the day that Casey had found out Julia was lactating—and, perhaps more importantly, that Julia hadn't denied that she had been fucking me and breastfeeding me without Casey being involved, and, perhaps most importantly of all, that Julia and I had allowed Casey to be sexually humiliated by our intense focus on each other when Casey was fully open to a relationship involving all three of us—Casey had been a little depressed. I couldn't blame her. I had shown that I couldn't reassure her that she was the center of my life, but she still didn't really want to leave me. Nor did she want to cut off her relationship with her cousin. I thought secretly that part of that was that she was still hoping she could be in a sexual relationship with Julia and her lactating breasts, too.
Casey seemed depressed but she wasn't catatonic. In fact, though I slept in Julia's bed for a week after the night of the big discoveries above, I returned to hold Casey in our bed the following Sunday, and on Monday morning before work, I awoke to something I hadn't in a very long time.
I stirred from my sleep and Casey had already taken my cock deep into her wet, unbelievably tight pussy. She was facing away from me in reverse cowgirl and looking down at my balls, fondling them. I could see in the long mirror in the corner of our room that she had a look of total longing and reverence on her face. It was the hottest she had looked in a long time—like it was obvious how much she worshipped my cock and my balls. She was twisting her cunt on my cock like it was her fist.
"Casey," I groaned. "You look so fucking hot."
She made eye contact with me in the mirror. "I'm just so glad you came back. I...don't laugh at me, but I have been wanting to show off my ass for you."
I couldn't explain how it was happening so quickly, and I don't think she could have either, but Casey's ass really had plumped up without losing any of its tone or suppleness. Watching it bob up and down was an incredible wakeup call. I gave it a smack just to watch the fat bounce.
"Turn around," I said. "I want to see your beautiful face and know if your titties are growing too."
They were. Casey had always had nice dark pink nipples, perfectly centered in her B-cups and nice to suck, even if they hadn't been a source of intense desire for me like someone like Julia's tended to be. But Casey was filling out. There was no way these were B-cups anymore, and it didn't seem like hormones were suddenly going to take them back where they had been easily. As I pumped my rock-hard cock into her, her breasts slapped together in a way they never had before. We both moaned at the sound.
"Baby, can you tit-fuck me?" I said.
She smiled as she climbed off of me. "You never call me baby. I like it."
Oh, fuck. Julia had made that our thing with her focus on enjoying being called it so much. I made a mental note not to let this slip-up happen around her.
But in the meantime, I was distracted by Casey's breasts around my penis. There was no way this could've happened a couple of months ago. She looked up at me and smiled again. "I love smelling my own pussy on your dick," she purred.
"Suck it off," I ordered her.
She planted a lewd kiss on me right as a small burst of precum coursed out. I groaned in pleasure as she loudly slurped it up with her tits still wrapped around me and jerking my cock.
"Oh, do you like the noise?" she said coyly. She took my cock deeper in her mouth, holding her breasts to touch my balls instead (not a feeling I regretted at all), and slurped loudly, letting her saliva drip out of her mouth to coat my cock and then guzzling it back up greedily. It was so hot how much she wanted me and wanted to please me.
But something in my brain switched and I started begging her: "Casey, I want to come in your pussy. I want to come deep in your pussy. Come up here, baby, I want to come in your pussy." She lay down beside me and I speared her pussy with my cock and her mouth with my tongue. I didn't know what was going on, but I just wanted to be close to her, feel her in my arms. "Baby, baby—unghhh." I felt my cum gushing deep inside her, and more than that, I felt her body start to tremble and shake, and her own fluids gushed out from deep within, coming all over me. I kissed her hard and we stayed locked together for an unusually long time.
"I...don't know what's going on," I said after we'd rolled off each other. "I know this must be confusing, but I guess I really missed you."
"Listen," Casey said. "I know it's a Monday, but will you play hooky with me today? Can we at least have breakfast out of the house so we can have a conversation without Julia potentially hearing? I'm not mad, I really just want to spend a little bit of time with you."
The vulnerability made my heart swell. Maybe it was my protector instinct. We got dressed and headed out in separate cars as usual, but we met up at a beach cafe where we had gone on some early dates. It was a coffee in the morning, grilled cheese for lunch, beer in the evening kind of place, and being there with Casey and her blonde hair and surfer legs made me feel like I had won the lottery.
