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.
Kristine babbled, "Oh fuck, I love it, ream my ass out, cream me so deep baby!"
Jason was happy to do so, as he gave Kristine an ass-filling fuck. I felt a perverse pleasure, as I rode Jason's ass hole, he was grunting and growling, umm, the sights, sounds, and smells of hot lust filled the cabin, and I was letting our gasps and cries of pleasure, the two dildos rubbing against each other was making my pussy roar with lust as my ass-hole was sending out throbs of pleasure in concert. Oh god, I could feel the wave coming for me, fuck, it was so fucking hot.
Kristine babbled, "Oh fuck, gonna cum, gonna cum so hard, yes, yes, yes, GRAWWWWWWWWW!"
Her scream of climax filled the room, a few seconds later, Jason grunted and growled as he thrust forward hard, eager to blast his load as deep as possible. That gave me the last little push, and my pussy started to spasm crazily, while my asshole pulsed in time around the butt plug, and I shrieked as I flew over the edge, our sounds making a symphony of lust to fill the cabin.
Kristine was right, she was a hungry eager lady, sexually voracious, and we formed so many combinations of 2 and 3, Kristine and I would 69 each other, our copious juices trailing all over our faces while Jason watched, we gave my brother a double blowjob, his cock and balls received thorough tongue washings until his cock was spurting, our mouths locked around his prick in a hot, wet fusing of mouths, and we fucked in various combinations, until Jason and I were exhausted, my pussy and asshole felt the soreness of being well fucked, his cock spent for the time being.
