Then I moved into position in front of him. The black lab climbed up part of my back and put his front paws on me. I grabbed his cock and guided it in...to my waiting slit. Letting it slip past my lips into my tunnel, I steadied myself on my hands. The dog eagerly pounded his cock into my cunt. The room was quiet except for my moans, the dogs pants, and the sound of his canine prick pumping into my dripping wet cunt. He rocked my body forward making me moan with pleasure. I spread myself farther. We eventually became airborne, and before we knew it, we were landing at our destination. During the conversation, I discovered she was a dentist. I was fascinated at her life story, and how she chose her profession. It was clear we were connecting nicely.As we landed, we said our good-byes - sharing common pleasantries. As she was visiting for only about 24 hours or so, and she was traveling alone, I offered her dinner after she'd conducted her business. I really did not expect her to contact. It’s difficult to describe, but while doing it ... while parading myself right in front of our brother totally naked, I’d never felt so sexy and alive in my entire life. Finally, I put my hands on my sister’s head and smashed her mouth to my breast. “Suck it harder ... really hard.”My twin sister did as I requested, but her eyes looked up, questioning me, so I answered her question “Harder”. And then, I was in pure heaven.My husband reached out and pulled and twisted my nearest nipple. He. K,” Dad replied. “Anytime you feel like it let me know.”“Thanks,” replied Rita “I just don't know what I'm going to do about Tom and I.”“It will all work out for the best, you take my word for it,” Dad said, leaning over and kissing her temple.I backed out and left and got into my car. Interesting, I thought to myself, she's crying on Dad's shoulder. I wonder how long that's been going on? I put it out of my head and went about my business and made my way back. By then Rita seemed to be back to.
