As I continued with my rhythm, only breaking the pattern to deliver the occasional smack to the centre of her bottom, I could feel her acknowledgement... of this challenge as she squirmed against my legs. Although controlled, her vocal responses gradually increased. “Oh God, OUCH! It hurts, Oh God, it really hurts, AAAGH!” Presented for real with this glorious bottom which held such appeal for me, it proved impossible not to recall some of the many fantasies this very bottom had featured in for. "It's not very big" Jay said apologetically, but she loved it and when we went down to the shop to tell Mister Singh that she would be staying with us for a while, he was quite relieved that she was able to buy booze legally and said that she was welcome.It was a bit crowded in our bed that night, but at least Frankie and I were able to sleep in each other's arms and it had been such a great weekend that we were ready for a good night's sleep.The next week was taken up with preparing for and. Jill was moaning in ecstasy as she had orgasm after orgasm. Then when she was loose enough this big fucking dog rammed his monster knot in Jill's stretched out cunt. Now they where locked solid and no fluid could leek out and the dog was pumping Jill full of his sperm. Then he tried to pull away but couldn't because of the size of his knot and how small Jill's pussy was and he had to stand there ass to pussy as his knot gradually drained its thin fluid in to Jill until it was small enough to. No one would be there for a while so I knew we would be safe from being caught. "So, what do you wanna do?" he asked. "Well, we could make out." I said shyly, I was beginning to chicken out. He made his way closer to me and pinned me against the lockers and started rubbing my thighs and kissing my neck gently, eventually finding my lips. I then dove my tounge right into his mouth, I'm sure he was surprised. As we were sloppily tounge kissing, I remembered how hard he had gotten when first.
