My Labrador and I enjoyed similar sessions. I occasionally wondered if her furry pussy could accommodate my aching cock, so while she was laying on her back, I began fingering her twat and she obviously enjoyed it, so I eased the head of my dick in her creamy snatch and then fully penetrated her and to my exhilarated amazement, she enthusiastically began pumping her pelvis upwards to meet my pounding dick.
After an extended period of sliding my dick in and out of her snatch, I'd slowly fuck her doggie style and then I'd sit upright on my couch and wrap her luxurious pussy around my cock with her facing me to slowly hoist her body up and down and revel in the delicious sensation of the thrilling taboo of my throbbing cock in my dog's delightfully velvety pussy.
Then without pulling out, I'd stand up to walk down the hallway while vigorously bouncing her twat up and forcefully down on my dick until I reclined her back on my bed to resume slowly sliding my dick in and out.
I always finished by increasing my tempo until I clutched her rump with both hands and squirting my cum into the deepest depths of her quivering cooch while she excitedly wagged her furry tail against my twitching balls.
After catching my breath, I'd withdraw my deflated dick from her twat and she'd always jump up and run in excited circles and then sit down and lift one leg to greedily slurp my cum oozing from her thoroughly satisfied cooch and then slather her tongue around my cock to clean me up.
She was a fantastically devoted cock-whore and cum-slut.
