He calls Elizabeth.

It took just a moment for my shaking hands to find my flip phone and hit Elizabeth's speed dial.

"Hello?" She sounded surprised. I put her on speaker.

"Hey, it's your boyfriend. I'm... here with... Jessica."

"Hello, Jessica." Was Elizabeth being polite? I couldn't tell her tone through the tinny speakers. Jessica was at a full blush. "Ian told me that you're his... um... his date this evening. I hope that you're treating him well."

There's no script for a moment like this. Here's my girlfriend, on the phone, teasing another woman. Jessica was lost for words, for a moment, before she found her courage.

"We're having a good time. He's such a sweet guy. You're really lucky to have him."

"Thanks!" Elizabeth cheered into the receiver. "I miss him and I know he misses me."

"Is it true..." Jessica fidgeted. "Is it true that you... loan him out sometimes?"

After a beat, "You want to borrow my boyfriend?"

My heart was pounding in my chest. I could see Jessica's arousal in her hardened nipples, her quick breathing. We were running hot, just waiting for permission from Elizabeth.

"I feel kinda bad," Elizabeth explained slowly, "I've had plenty of fun at college but Ian hasn't had a chance yet. I don't want him to go without. Would you mind... taking care of him for me? Be good to him, okay?"

That was all the permission that my partner for the evening needed. Jessica pressed forward, closing the distance between us, and pushing me backwards onto the couch. Her lips were hot, soft, and tasted sharp and sweet. I set the phone down on the coffee table beside us as she hastily removed her thin top and my t-shirt. Her hands shot to my belt, mercifully freeing my erect member from my pants as our tongues danced.

She broke off the kiss with a wicked grin as her small, warm hand found my shaft. A shiver ran through me as I watched her crawl down between my legs. Her petite, pale, rounded shoulders contrasted against the enormous and flawless cleavage straining against her sports bra. As she took me into her mouth, her dark hair fell over her face. Next thing I knew, those lips that only moments before had been joking and laughing with me were wrapped around my cock.

"What's happening?" I heard Elizabeth ask.

Jessica made an obscene sound, wet and sloppy. Elizabeth caught the cue. "Is she going down on you? Lucky you. I'm all alone here tonight," she purred into the phone. "Be good and give her the same treatment. He's really good at it."

Jessica was practiced in her treatment of me. She knew just how to stimulate the head, gently, while stroking the shaft. I didn't want to finish too quickly, so I softly tapped her head. With a teasing final lick, she brushed her hair out of her eyes and looked up at me. "My turn?"

"We're wearing too many clothes," I answered. With a single motion, I stood and dropped my slacks and exposed my erection to the warm room. Jessica smiled as I reached for the hem of her bra. The fabric barely cleared her now gloriously exposed tits. Their massive size in contrast to her tiny frame was almost comical. I couldn't help but mash my face in between them, groping roughly with both hands as her hot scent filled my brain, driving me mad. I moved to run my lips across her puffy, engorged nipple as I let my other hand drift beneath her waistband.

Her panties were soaked. She needed attention. I peeled the thin shorts right along with her underwear, which clung in a mess to her perfectly smooth, shaven sex. Her arousal filled the room, begging for me to taste. I kissed down her flat abdomen to her hips, kissed up her thighs, and gave her pussy a small lick that sent a quiver all over her.

Jessica's pleasured moans weren't the only sounds in the room. From the phone on the table came the distorted but unmistakable signs that Elizabeth was playing along at home. As I licked up and down Jessica's folds, sucked her clit, and built up speed, I heard my girlfriend ask, "How is he?"

"He's... he's really good. You... OH! Have him trained so well. Oh my God. YES! Use your fingers, please. Please. Uhh... oh..." As my fingers entered her wet slit, Jessica lost coherence. I could feel her rough g-spot on the other side of her swollen clit, demanding attention.

She was close when Elizabeth interjected, "Aren't you going to fuck him?"

I felt Jessica's hands on my face. I looked up her magnificent body to her tense face. She was biting her lips and nodding unconsciously. As I rose, she shamelessly held her legs apart, offering herself to me. I rubbed my cockhead at her entrance.

"Please!" With her cry, I slipped gently inside her. She moaned in ecstasy as our bodies joined. My hands found her narrow waist and I practically pulled her onto myself. She grabbed my shoulders tightly and suddenly I was holding Jessica in midair. With a graceful swing, she wrapped her leg around my arm for leverage. Her hips slammed onto my cock, violently bouncing her gorgeous tits.

I rotated and dropped us back onto the couch so Jessica could ride me. She was pounding away wildly now, shaking out her hair, squeezing her breasts. I held my hands at her hips and focused on the feeling every time she took me into her pussy. Over Jessica's shameless moans I could hear from the phone the unmistakable sounds of Elizabeth nearing her climax. Jessica seemed close too, now rubbing her clit and grinding my dick against her g-spot.

Elizabeth came first, straining the tiny speaker with her high-pitched, glorious agony. The sounds of my cumming girlfriend set Jessica off. She squeezed a nipple so hard I thought she'd hurt herself as she pressed her body roughly against me. Her inner walls tugged at me, begged for my cum. Jessica pulled me into a savage kiss and started thrusting her hips again. Her wet walls convulsing on me, I exploded inside her, filling her completely.

She smiled. "Nice to finally talk to you, Elizabeth."

"Thanks for taking care of Ian. Can't wait to meet you." The phone clicked off, leaving me with a marvellously naked coed stuck on my lap.

We hopped into bed, though we didn't sleep much. As soon as I recovered, we made love a second time, with a little more privacy. Still, it felt like I was doing what Elizabeth wanted. I wasn't sure how Jessica would adapt to this bizarre situation. Hell, I wasn't even sure what I thought about it.
