There were multiple locks and the first lock of the door got unlocked. My sister-in-law then slightly pushed me back with her ass in the bending posit...on. I was carrying food bags in my right hand. I had locked it in my finger.I slowly moved my hand towards my sister-in-law’s ass and started feeling that ass little by little. From her right ass cheeks to the left, from the left to the middle, from the middle to her ass hole, and from her ass hole to her pussy. I realized that my sister-in-law. My hands are moving to the tops of her thighs, rubbing them slowly and sensually. " What are you doing?" She breathed, again feeling helpless against my touch, my hands exploring the tops of her thighs, the tips of my fingers moving dangerously towards her pussy. She gasps as she feels my hardening cock pushing against the small of her back. " Just trying to warm us up," I sigh, " I've just remembered that you don't have any panties on right now," I purred into her ear, roughly biting the lobe. I put my other hand on her mouth as she started to moan, her eyes closed as I slipped a finger in her pussy and started to play with her as she neared closer to her orgasm. Her knees started to buckle as I held her up by her hand over her face.I then slowed down and stopped, taking my fingers out and licking them as I tasted her juices. She looked at me confused and whined in frustration. I turned her around and kissed her and told her that there would be more tomorrow and then promptly left. Her paddle leaned over her shoulder, Mara dangled her fingers in the water, waiting for her father and brother to make their way across the sparkling surface of the lake.Though the search was tedious, the company was good. Wade was as full of good humor as ever, joking and singing as he paddled along in the seat behind her. Everyone had stories to tell, many of which were new to Mara by virtue of her being too young to actually remember the incidents at the time. Despite the camaraderie, none.
