“Again.”
I winced. I thought I had trained enough for that day. I thought wrong. I got back down on my hands and knees, reached behind and spread my ass cheeks open, burying my face into the ground. I felt the thick silicone dildo press against my tired asshole, ready for another round. It entered me slowly, and despite training all day it still stretched me wide, as my once tight asshole got used to the thick cock.
In no time, the machine whirred to life, thrusting the cock in and out of my asshole hard and fast. My big, hanging boobs swayed against the floor with every thrust from the machine.
“Enjoying yourself?” he asked me.
“Always when I’m with you Sir,” I responded back as usual.
I kept my ass cheeks spread open while the toy continued to fuck my ass. This was what I signed up for after all; I wanted to become an anal slut, and he told me this was the best way.
The fake balls of the cock slapped against me loudly, as my pussy had been slowly leaking my juices since we started this session. Something about giving in, being used, and having my asshole stretched drove my pussy wild.
The cock reached deep in my ass, filling me in ways I never knew I needed. My pussy ached to be filled too, but as that wasn’t allowed, I was training to cum only from anal. And I was close. The machine continued its onslaught, in and out of my ass. I moaned in pleasure, my toes curled and my whole body tensed.
As the orgasm hit me I couldn’t move, I couldn’t even moan, as pure orgasmic bliss spread from my asshole throughout my groin, causing my clit to ache and my hips to convulse. That drove the cock deeper inside me, extending my orgasm, as my whole body now shook.
He finally shut the machine off, with the cock deep inside me still; my pussy twitched as my grool dripped down my bare lips, making a mess on the floor below. I caught my breath and slowly removed the cock from my ass. As I continued spreading my cheeks, my bright red asshole gaped open, showing off how stretched and well used it now was.
I longed to have my pussy filled, as my neglected clit ached to be used. From now on though, it was anal orgasms only.
I stood up and smiled, proud of how quick my last orgasm came about. He walked around me, looking at my dirt covered breasts hanging down, my bare mound, my wet mess between my legs.
“Again,” he said.
As I got down on my hands and knees and spread my ass, I could feel my asshole was still slightly gaping open. The training was slowly paying off. Then his cock slid inside my ass.
