"Oh. My. God. That's hot," she said to Alice.
"I know, he's so fun to dominate. Fuck, it's so sexy to put him in his place."
"Keep sucking, darlin'," Nikki coaxed, hands on my head, fingers entwined in my hair, "I can feel myself in your throat."
Nodding, tears coming to my eyes, I grabbed her beautiful ass and snaked my tongue out beneath her cock to get more in me. Sensing my need for breath, Nikki pulled out, trailing thick deep-throat lube between my lips and the end of her cock. After my one breath she pulled my head to her and started to fuck my face. I relaxed my throat and tightened my lips around her shaft as she pushed it into me.
Sounds of my gags filled the room as I allowed her to assert herself over me more directly. I gave myself to Nikki as fully as Alice did. Nikki pulled out so I could catch my breath, then feeling me extend my neck to get her cock back in my mouth, slid her cock back down my throat. Alice could see Nikki swaying back and forth to the motion of fucking my mouth.
With my right hand busy on my cock, which had become erect again, I reached up with my left and nudged her legs apart. As she complied I placed my middle finger gently against her slit, my throat still enveloping her cock. Putting pressure on her pussy I pulled off for a breath and looked up with a questioning glance. "Go for it," she husked.
I slid that cock back in my mouth and fucked it with my throat as I slid my finger between her folds. Moaning, clearly close to coming, myself, I stroked Nikki's g-spot. Back and forth on the dildo in my throat and mouth, on her g-spot: I was fully Nikki's bitch.
"Look at that slut go," Alice's throaty voice reached our ears softly. Nikki grunted in reply as I moaned and let her cock pop in and out of my throat, deep gagging noises surrounding everyone until, with little warning, Nikki tensed up and jammed her cock in my throat, holding it there as she clamped her pussy down on my finger.
At this, I pushed down on Nikki's cock and screamed through my nose as I came again, catching it in my hand. I pulled back for air then watched Nikki's cock bounce in my face as she continued to come. As we came down from our respective peaks, Nikki sat back on the bed next to a curled up Alice.
"Oh, look, the bitch needs to clean up again," Alice grinned, pulling my hand to her mouth. "I'll help this time, baby." She cleaned my hand and swallowed everything. Nikki flopped back, exhausted, while I asked for some help up off of my knees. Alice pulled me up to join them on the bed.
"Who's a happy bitch," she crooned.
"I'm a happy bitch, M'am, thank you both so much," I gushed.
"Not just a bitch anymore, either, are you," Alice's voice taking on a more somber tone as she made sure I saw her grab Nikki's hand.
"No, M'am," I asked, the reminder slowly returning to the fore of my consciousness.
As Nikki squeezed back, Alice said gently but firmly, "You. Are a cuckold now. This cannot change. You can't undo it. You'll always be a cuckold." Holding Nikki's hand and my gaze simultaneously, she continued, "I was reluctant, as you know, before tonight, but after what just happened, there's no way I'm going back. I love you more than ever and you'll always be my primary partner but you'll always be my cuckold as well. That's what you want, isn't it?"
The love was clear in her eyes as was the certainty of her statement. There was no returning. I nodded.
"Good, because I don't want to stop this. It's too good to stop, don't you agree, Nikki?"
"Fuck yeah, I agree," Nikki replied. "Brian," she continued, "thank you for introducing me to your girlfriend. Don't worry, I'm not interested in stealing her away, though I probably could, if tonight is any indication." I shuddered, a mix of fear and pleasure suffusing my body. "But I will be back to fuck both of you. Soon, right baby?"
Twisting around to Nikki, Her pussy peaking out between her tanned thighs, Alice kissed Nikki deeply, "That's right, baby. We have lots of plans together and for Brian, don't we?"
Nikki just started chuckling as I craned my neck towards Alice's bulging pussy, so close…
