Aunty requested me to drop Priya from the tuition coz it was going to rain. I said ok as usual and started my bike and proceeded towards classes all o... sudden on the way it started pouring heavily I had no options I just parked my bike by the side and stood in a lobby of a house near by and called up Priya to say wait for me as soon as the rain subsidies I will pick her up. She agreed accordingly. During my conversation the house door opened and what I saw a beautiful girl with pinkish. From what he could make out, it looked like she had a pretty face although he couldn't see it too well."What in Hell is she doing??" It looked like she was climbing up higher onto a wet rock dangerously close to the crashing waves. "Damn! She's gonna get killed!" he swore out loud. He dropped his coffee cup and cigarette and ran as fast as he could down to the rocks, carefully watching his own footing as he made his way to her. The rocks were slippery and wet and very dangerous.She did not see. The only thing left covering her big round ass was a skimpy little pair of black panties.I took off my clothes and pulled off my boxers to free my already stiff cock. I rubbed the tip of my cock along the entrance of my sister's dripping wet pussy, coating my cock in her juices.“ok sis, you continue what you're doing there and I'm gonna fuck this sexy pussy of yours” I said, still teasing her snatch.My sister just nodded her aknowledgement and I began slowly pushing into her pussy, she groaned. Wide-eyed and breathless, Cindy gulped and gulped until she'd swallowed the mouthful of hot jism, then she gasped and stared in disbelief as the animal-cock pumped and squirted and gushed huge quantities of come. She heard the stuff splash onto the earth and it startled her.Wanting to see more of that action, she lunged to her knees and grabbed the jolting horse-cock in her hand. She whacked his prick fast and furiously to make it come some more so she could watch it. Her hand did a good job..
