Kristine grinned and looked over at me.
"Kayla, are you still an anal virgin?"
Holy fuck, did she just ask me that? I was momentarily stunned.
Kristine put on her "teacher in control" tone, and she barked, "Kayla, I asked you a question! Have you ever taken it up the ass? Has any guy's hot rod taken a trip up your chocolate speedway?"
I could feel my face blushing furiously, as I meekly answered, "No I haven't Miss Marston."
She chuckled, "Miss Marston, so formal, let's keep it on a first-name basis shall we?" At my nod, she continued, "Well I am going to take care of that, I have the perfect toy for that."
She lifted out the item she had chosen and held it up for us. It was a deep purple, double-pronged dildo. Straps were attached to the sides, and my mind lit up. The dildos were one atop the other, both looked to be about 7 inches long, with just enough space between them for...OH MY GOD.
She saw the flash of recognition on my face, and she chuckled, "I'm going to strap this baby on and fuck your pussy and your virgin ass hole at the same time. You'll love it, Kayla, on the bed, lay back, now!"
I quickly scrambled into position, my mind was spinning. My mind was worrying, oh god, would it be painful? What if it hurt too much, and Kristine would just continue, and ride me hard, raping my ass?
"First, we have to get your ass hole ready for it."
She stuffed two pillows under the small of my back, lifting my ass up. I felt her hands cup my cheeks, then they were spread apart. The idea that Kristine was looking right at my ass hole, exposed to her eyes, sent thrills through me.
Kristine's voice was a soft coo, "Mmmmm, oh yes, beautiful, your tight pink virgin rosebud, so sexy, enjoy this baby."
I felt my naked body quiver as Kristine's face lowered down and nuzzled warmly between the spread of my ass cheeks. I let out a cry of sheer pleasure as I felt her lips pressing against the tiny, ultra-sensitive pucker of my ass hole.
I let out another cry of sheer delight as her hot, wet tongue slid out, long, wet licks sliding over my ass hole, oh god, it was twitching with excitement, her tongue probed at me, pressing slightly into my ass hole, which clenched shut. I worked on making my ass hole loosen up, and gradually, it gave way, and Kristine's tongue was able to dip into me, swirling her tongue around the tight grip of my last virgin hole.
I was grunting, growling, purring, god, it was like nothing I'd ever felt before, my asshole was ultra-sensitive, and the sensations were so exquisite it was almost painful. I saw Jason sitting by the bed, mouth open, cock stiff as granite, staring at the sight of his sister in the grip of burning, sizzling lust. Then I growled louder, as I felt one of Kristine's fingers dip into me. Relax, relax, I told myself, as Kristine slid her finger up, testing the grip of my virgin hole. After several minutes of her finger probing my last virgin hole, she lifted her face up.
"Oh yeah, I think you're ready baby."
I watched her as she tied the dildo's straps between her legs and around her waist, fitting them into a buckle on the back, adjusting it slightly, and making sure it would stay in place.
I felt the squirt of slippery oil being applied to my ass, Kristine's fingers slid around my tight, twitchy rim, making me coo with pleasure, another squirt of oil, and her finger slid inside, spreading the oil around my inner hole.
