Mia was staring right at me now. "Well, if she forgets we'll just have to remind her." So far I'd been holding it together, but now a cold hard shock jolted my pride and my pussy in equal measure and I heard a soft whimper escape my lips. Jesus, what's wrong with me? No longer able to resist, my hand slid down and started stroking my slit.
Mia returned her attention to my husband and kissed him with fervor, grinding her pussy against his hardening manhood. She began to slide down his body, planting kisses as she went, sucking hard in a few spots to leave love bites I'd have to look at for days. She reached her destination and took hold of David's shaft, then dragged her tongue from his balls to his tip in one long lick, enveloping the head and sucking wildly for a few seconds. She looked over then and saw where my hand was. Her mouth popped off his cock and she replaced it with the steady stroking of her hand; he was powerfully erect now.
"Oh, man. Look at the little tart, she can't help herself. I guess you were right," she said to David. At this my eyes shut and my head fell, though my fingers sped up. "Aw, I think we embarrassed her. Are you embarrassed, Kimmy?" No answer. "Are you? " she repeated.
"Yes," I managed, but with more than a hint of annoyance.
"Embarrassed you need to find someone to fuck your husband for you? Someone better?"
"Yes, Mia."
"Oh, I think that's 'Miss Mia' to you, isn't it?"
"... Yes, Miss Mia." David just lay there with his hands behind his head, content to watch my humiliation. Mia snorted and went back to servicing my husband's cock. Seeing it in her mouth set off a trickle of arousal, along with a wave of jealousy. It's a magnificent tool -- pretty long, uncommonly thick, and always ready. He's a great lay, and I'd always felt gratitude. But now I had to watch as it was given to someone else, and it was carving up a small part of me. She attacked it with relish, twirling her tongue, stroking the shaft, working the balls, varying her technique. It was an inspired performance, which made it sting all the more.
But David got to appreciate it fully. His pleasure was obvious -- too obvious, for my comfort. He was more responsive than I've seen him in a long time, his body overcome with intermittent little spasms, and drawing out of him an "ah!" or a muttered "oh, fuck" again and again.
Mia stopped after just a couple of minutes. Her hand slowly stroked up and down and she looked up at my husband.
"Tell me: who sucks your cock better, me or her?" She didn't even look in my direction, and neither did he.
"Do you have to ask? You do, baby. She's fine, but you're just ... on a whole other level."
"Well that's just sad," Mia told him. "She's had so long to learn -- so, so long. Is she slow or something?"
"She tries her best," he said. He reached down and stroked her cheek with the back of his fingers. "She's just not you. That was special."
Mia beamed, triumphant -- she turned her head to let me see before looking back to David.
"Well, she's gonna learn something tonight, at least," she told him. Then, to me: "Get over here. Foot of the bed." She pointed to a spot behind her. Mia slithered up David's body to straddle him as I went over and crawled onto the foot of the bed, as ordered. She rose up so she was hovering over his crotch.
"I'm gonna fuck your husband now, Kimmy. It's your job to help, isn't it?"
"Yes, it is."
"Then help, cuck. Put him in me."
Oh, god. She was serious. I muttered "fuck" under my breath and heard Mia chuckle in response. I hesitated. Without saying anything more or turning to look at me, Mia shot her hand out and pointed, decisively, below her.
I willed myself to continue -- to reach my hand out, to take hold of the shaft, to resist the temptation to stroke it, to hold him upright. To aim.
Mia descended, and I could only watch as she found the mark. David's shaft parted the lips of her shaved pussy and she rocked back to force the first couple inches inside. She gave a surprised "Ah!" -- merely seeing it wouldn't have prepared her for his girth. Mia let out an amused groan as she rotated her hips and slowly began to swallow his shaft. I removed my hand, but kept my position behind them.
"Yeah, just stay there a second, Kimmy. Stay there and watch," she said. It seemed like she took more pleasure in taunting me than anything else that was going on. Her hips gave a happy little wiggle as she bottomed out, taking the last of my husband's cock. "Mmmmm, yes, right where it belongs. Get a good look, Kimmy. See what it's like when he's inside a pussy that's worth his time..."
I did see. A mix of emotions played across my face, but no one else would notice -- David & Mia were far too engrossed in each other. I sensed that I had to touch my own pussy as I watched my husband use hers, and I sensed that I had to get myself further away from their union; it was too intense. As they started to fuck in earnest, I slid off the bed and moved back to my chair.
Mia rode David; I watched, slack-jawed, and rode my right hand. If her youth and beauty were dispiriting before, they were positively intimidating now. She was lithe yet powerful, moving with a grace and confidence I could only envy. Mia started with a slow rocking back & forth, her hands braced against David's chest. His hands roamed freely for a time -- stroking her face, squeezing her breasts, playing with her nipples, gliding down her sides -- before landing on her hips to help guide her. They stayed like that, grinding away at a steady pace with only the faintest hint of acceleration, like an impatient metronome. The whole time, their eyes were locked onto each other's -- in that moment, I was irrelevant. My fingers sped up. Mia broke their silence.
"Oooh, David, honey, you've got something special back there," she sighed. Mia reached back to caress his balls as she kept up her rhythm. "You deserve the best..."
"Oh yeah, this is the best," he told her. "You feel so ... fucking ... good." At this their pace sped up and they became more frankly passionate. Seeing this sent me spinning. An embarrassingly wet smacking sound could be heard from my chair as I worked two fingers inside myself, but my involuntary moan finally gave me away. It was David who first looked over and addressed the situation.
"Kimberly. You said you were going to be good. You know not to cum without permission -- you wouldn't dare. Right?" I hurried to shake my head but couldn't stop my fingers.
"I'll be good, I promise," I said. Our exchange had done nothing to slow my momentum, and I was forced to ask almost immediately: "Please, sir, may I cum soon? Please ... I'll be ... ohhh ... I'll be good."
"Oh. No, sweetie. I'm not the one you need to ask," he said. Oh, shit. "This college girl is in charge of your pussy tonight -- we both thought that would be best." Mia had slowed her grinding while she watched the show, an impish grin cast in my direction. I steeled myself to beg.
"Please, Miss Mia, may I cum soon? I need it..."
"Aw, poor baby. And what'll you give me if I say yes?"
"What ... what do you want?"
"I want you to fucking wait," she said, reveling in her petty cruelty. "You cum when I say so. Think you can manage that, Kimmy?"
"Yes ... oh fuck ... I can." I slowed my right hand to a crawl. What choice did I have? Still my legs spasmed and I failed to stifle my moans. I doubted I could hold back, and Mia could see it.
"No, I don't think so, pet," she said. "Get your hand off that cunt. We won't have you popping off before I'm ready." A tortured groan escaped my lips as I tore my hand away. My eyes clenched shut and I heard Mia giggle.
"Now, where were we?" I heard her say. The creaking of the bed sped up and my husband grunted. I bowed to my predicament and watched, forced to settle for my hands roaming across my own body and stroking my own nipples.
