I’m 19 years old and my sisters 18. We both know that neither of us are virgins. But witnessing my sister with a silver dildo shoved in her pussy is... the most erotic sight I have ever seen. She is five foot six with long auburn hair and green eyes. She is very athletic due to volleyball and cheer leading. She was moaning louder than ever. Her pace kept increasing until suddenly she shoved it as deep as she could and arched her back high in the air. She had the most intense orgasm I have seen.. ” She almost felt bad.“Get ready to lose that bet, honey.”It was clear that she had underestimated him. She needed to entice him to get out of the water before the minute was up. She let her towel drop to the snow. Martin inched closer to the shore but stayed in the water. Nova could feel the intensity of his eyes.“Nice try, Nova. But when I get out of this water, you better be ready for me.” Reality finally hit that she would lose and what the consequence would be. She watched him saunter out. Her tight grip doubled my pleasure and I knew what I had to do next. Though I continued to suck her milk out, I licked and kissed her flesh more than I sucked her. As a result, her hand moved tighter on my cock.My cock felt thinner as she squeezed gently with both her hands. Again she held my tip and pressed onto the sensitive part of it. I moaned again making sure I did not leave her nipple. I fell onto her more and took more of her flesh.She was jerking now and then as my mouth pulled half of. "I finished and brushed my teeth going out and sitting at the table. Kat immediately stuck a thermometer in my mouth and sat looking at me. I tried to smile at her, but I was still feeling a little queasy. When she took it out of my mouth and looked at it I could see the surprise in her eyes as she looked at me."You don't have a temperature, Jon. I think I will call the doctor to run a few tests on you to see if maybe something else is wrong that I can't see. This is really a little strange to.
