I walked with Prachi far enough away from the house that we couldn’t be seen and then we stopped and I kissed her. I’d forgotten how difficult a f...rst kiss could be. As we embraced I took in how different her body was compared to Madhu’s. Prachi’s breasts were Medium it made her nipples seem bigger by comparison and my hands caressed her tight hips and perfect ass. It was exhilarating, and it only got better. She got down on her knees and pulled out my cock. She purred that it was beautiful and. Uh..." she grunted as he pushed his cock deeper and deeper into her ass. Soon she could feel his swelling knot ,which she knew was larger than the first dog's, press up against her stretched asshole."Knot me!" she cried. "Make my ass yours!" She pushed back against the dog hammering her ass, until she felt the growing knot push into her rectum.She screamed, half in pain, half in ecstasy as the knot stretched her ass and entered her. Once he was fully in her, she could feel his knot rapidly. Is that OK with you?"I instantly realised that I really had no choice in the matter “Ok let’s go". I replied heading for the door as quick as possible encase my wife changed her mind, as we were only 5 minutes’ walk from our hotel. As we headed down the street I walked ahead of my wife and Matt who were walking arm in arm behind me. I could hear my wife giggling and as I turned round I saw Matt whispering into her ear as his hand groped her ass under her dress. She was totally absorbed with him. We fucked and it didn't cross my mind again until I saw what she was wearing when she came into the room when my buddy Ron was over a month later. She had on hip-hugging sweatshorts and a clingy but loose v-neck top on without a bra. Her long legs led up to beautifully womanly hips and a bubble-butt. Her full and dense C cup breasts hung just a bit but her prominent nipples pointed straight out. When she moved they swayed and their curves strained against the fabric. Holy shit she looked hot..
