Myong gasped as the plastic dildo entered her pussy. I pushed forward and easily slid the toy to its' fullest depth. It seems Myong had gained a larger pussy along with her extra weight. I turned Myong over and entered her doggy style, I giggled a little girly laugh as I saw her larger ass begin to jiggle with every thrust.
I was getting bored with having the strapon, so I willed myself to have the real thing. I immediately felt the familiar pleasure of a real cock between my slender legs, sliding in and out of her wet pussy. Even though I now had a 10" long, 3" diameter dick, it still felt loose inside Myong's pussy. I admit, I was a bit turned on by her ass jiggling and the next thought that came into my mind became a reality as soon as I thought it... I was going to have to be a bit more careful...
The penis between my legs began to grow and take on a darker color. The skin grew leathery and I could smell the equine scent as the horse cock took full form. It was huge and definitely filled up Myong's pussy as I could tell from her squeals of delight. I slid it in deeper and finally hit bottom as she gasped in pleasure. The glistening pussy juice made the horse dick slippery and I pushed in and out as she came, squirting all over my thighs. The pressure of her squirting orgasm pushed my horse cock all the way out of her pussy, but I quickly slid it back in to her soaking hole. I picked up my thrusting pace and felt my balls begin to tighten as I approached my climax.
I came violently, gushing a gallon of horse cum into her pussy. Myong moaned with delight as she was filled with my equine fluid. I thrust deeply one last time as I shot the last of my cum deep inside her.
She fell to her stomach as I withdrew the massive member, quickly wishing it back to the small plastic strapon. Myong turned and looked at me with a glazed eye and sweat pouring off of her now chubby cheeks. We cuddled in the pool of horse cum and drifted off to a blissful sleep.
This was going to be fun!
