Kristine was so right, walking around, feeling the fullness of my butt plug stuffed securely between my cheeks, keeping my ass hole pried open, was erotic beyond measure. Every step made my body tingle, and when we went into the local coffee shop and sat down with a cup, I couldn't help squirming my ass around, fuck, it felt so good.
Kristine cooed, "Feels good, doesn't it Kayla?"
I whispered back, "Yes, oh my god, it feels beyond good!"
She whispered back, "When you come to my class, I want you to have that butt plug where it belongs! Since your class is the last one of the day, after class, I will check that your butt plug is stretching your tight, sweet hole, and I will reward you accordingly."
Turning to Jason, she purred, "And how does it feel to have your ass hole filled up, you bad boy?"
Jason turned red, but he admitted, "It feels good!"
Kristine smiled, as she replied, "You see, there's nothing gay about feeling those surges of pleasure, and admitting the pleasure is really good. I know that at your age, more than a few guys are scared out of their minds, when something happens, like a girlfriend that wants to get adventurous, plays with that tight little hole, and all he can think about is 'Oh fuck, I'm turning gay!' "
A few minutes later, she purred, "Let's go back to the cabin, so I can give you a reward for being such hot, willing students!"
Back behind closed doors, she cooed, "I love getting my ass hole fucked, Jason, you get to explode a nice juicy load up my bunghole and to make sure it's a big load, Kayla, you are going to strap on a dildo and fuck your bother's ass while he fucks my ass!"
I was almost trembling. Kristine reached into her backpack, and with a smile, brought out a copy of her strap-on. My lust roared, and I was almost transfixed by the sight of that strap-on. Oh god, as I fucked Jason's ass hole, the built-in dildo and butt plug would give my hot, wet holes a filling, enjoyable ride.
"Bend forward my students," Kristine purred.
As I did so, I felt Kristine tug gently, and my ass surrendered the butt plug that had been between my cheeks, to make room for my strap-on's butt plug. Jason's butt plug was pulled out, and I felt the surge as I realized that I would be fucking my brother, very soon. The strap-on's butt plug had a nice, filling flare, tapering down to the stem that my tight ass would pucker around, keeping my asshole stuffed with 5 inches of ass-stuffing pleasure.
"This is your very own strap-on, Kayla. Whenever Jason wants his ass reamed, you'll have what he needs, and if you want to have some fun with a girlfriend, and of course with me, you'll have the perfect toy, it will give you as much pleasure as you can dish out."
I stepped into the harness of the strap-on. Pulling it up my thighs, I reached inside the harness, angling the dildo towards my pussy. I spit on my fingers and rubbed it over the butt plug, then I pulled it up, feeling Kristine's fingers pulling apart my ass cheeks, guiding the butt plug. The dildo glided easily into my pussy, I was so wet, and I felt the butt plug press against my ass-hole. I squatted, pulling the harness tight, and ummm, I let out a growl as the butt plug entered, the flare breeching me, then lock into place, as I buckled it tight around me. Both my holes stuffed, oh fuck, it felt so good!
Kristine smiled and took what she told us was a vibrating egg. She slipped it into her pussy, and turned a dial on the small remote control, and gave a soft purr of pleasure.
"Ummm feels so good, I love vibrating my pussy while my ass gets fucked," Kristine cooed as she took to hands and knees. "Mount up Jason, bury your cock, then hold still so Kayla can plunge the dildo into your ass-hole."
Jason quickly did so, and Kristine moaned as Jason pulled her ass cheeks apart, nudged the head of his cock against her, then powered it up our teacher's chocolate highway. I grabbed his cheeks and pulled them apart, I saw the tight pucker, and my mind roared with lust, I was going to fuck my brother's ass-hole! I reached down, guiding the dildo head on its ass-opening path, and with a smooth steady push, Jason hissed as his asshole was violated, and I sank it in to the hilt. I was seeing through a red haze of lust as we paused for a moment, then after a few movements, we got into the rhythm, oh fuck, when Jason pulled back, I pulled back, when he drove forward, I did likewise, the dildo and butt plug were making my holes lust fueled furnaces.
