Coming back to the here and now, Jason had just ended his story. I saw Kristine smiling, she was taking an eight-inch strap-on dildo and harness out of her backpack.
"Kayla, come take a look at this."
I did, and my eyes widened in surprise. On the inside of the harness, where the wearer's pussy would be, was a 6-inch dildo, and around the back was a built-in butt plug, a nice, ass-filling flare, tapering down to the stem that would lock it up the ass, it looked to be about 5 inches long.
"This is the best," Kristine said, "While you're riding your partner, your sweet pussy and your tight ass hole will get all the hot stimulation you need. This harness makes me cum like crazy."
Taking to her hands and knees, she purred, "Lick my ass, Kayla, get my tight ass hole all ready for my nice, filling plug."
I kissed all over her gloriously shaped globes, the idea that I was kissing the ass that most of the guys in school would kill for, gave me an erotic charge and a heady sense of power. All those horny guys and I was the one kissing Kristine's fabulous rump. I watched her hands come back, she gently grabbed her cheeks and pulled them apart.
"Now my ass hole baby, " she cooed.
The rose-shaped puckered opening was right before my eyes. I stared, feeling the lust shoot through me. It was all pink, twitchy with anticipation, I was trembling as I applied my wet tongue and ran it around the tight rim of her pink rosebud. Kristine moaned deep and low, which spurred me on, and I started to lick eagerly, long, full tongue sweeps. I gently nudged her hands away, and my hands took over, gripping her cheeks, and keeping them spread wide. She tasted so clean, so fresh, and my excitement was roaring.
Kristine gasped, "That's it, that's mmmmm, ohhhh, yes baby, drive that tongue up there...mmmm, oh yes, tight there...now just lick and finger my ass, lick my hot tight ass hole, I love it!"
I probed at her asshole with my tongue, I slipped a finger into her soaking pussy, lubing it up with gushing juices. I pulled back slightly and pushed gently with my finger. It popped inside, the tight clench was incredible. I hoped I wasn't hurting her.
Kristine purred, "Deeper, shove that finger in, wriggle it all around!"
Her moans and purrs of pleasure built up as I pushed hard, feeling the tight clench parting reluctantly as I breached her tight rosebud. I could hear a wet, squelchy sound join in. I saw Kristine's hands at her pussy, she was stroking her sweet pink hole, fingers of her left hand strumming at her pussy lips, while 3 fingers of her right hand were stuffed up inside her. The wet squish increased, as Kristine started to fuck herself faster, her fingers were now plunging in and out rapidly.
Jason was watching the spectacle of Kristine masturbating furiously, while I, his sister and lover, licked and lapped at Kristine's tight rosebud. His cock looked painfully erect, the foreskin pulled back and his fat juicy cockhead exposed and glistened with pre-cum.
As I finger fucked the tight rosebud, I was remembering the shooting thrills that filled my body when Kristine gave me my anal deflowering, licking and lapping at me before penetrating my virgin clench, and fucking both my wet, juicy pussy and my virgin tight rosebud, it made my body shiver in remembered pleasure. The fact that my ass was stuffed with my new Red Devil butt plug, helped to push my lust along. I pumped my finger in and out, my tongue licking around and around, Kristine was gasping and growling with pleasure.
"Kayla baby, pull your finger out, and lick at my tight hole, oh fuck, I'm so close!"
I happily did so, making sure that her cheeks were spread open as much as possible, I let my tongue go wild on her tight, twitchy rosebud, her ass hole was quivering, oh yeah, cum for us teacher, cum real hard, my mind whispered.
"Fuck, oh god, yes, yes, GAWWWWWWW!"
Kristine's body shook wildly as her voice rose up to a shriek, her tight rosebud was twitching crazily against my tongue, as she tumbled into orgasm, oh fuck, my pussy was a soaking wet mass of lust, I'd be stroking my pussy like crazy while watching Jason get his ass filled with Kristine's dildo.
When the last spasm had rippled through her body, Kristine stood up, stepped into the harness, and pulled it up. When it was halfway up her thighs, Kristine reached inside and angled the six-inch dildo against her, ready to be penetrated. Kristine's face was a study of anticipation, she adjusted her body, working the pleasure toys against her body, then her face lit up, the lust-filled smile and the soft coo of pleasure as both dildo and butt plug slipped into the eager, hot pink holes awaiting them.
She pulled it tight against her crotch, then adjusted the straps, and what a sight. Kristine Marston, our school's hot history teacher, with an 8-inch cock jutting from her loins, I snickered, wondering how many guys would be up for being boned by that stiff, hard dildo.
