This was as far as things had gone, but here was my chance."Bet you a blow job." I tried to say as casually as you like, but my voice cracked, betrayi...g my tension, though my shaking hand on her boob was doing the job perfectly well on its own. I had dreams of Susan on her knees in front of me as her soft lips enveloped my cock."Hmmm." She said, her fingers playfully measuring my length, causing me to wonder if I was going to explode and wishing I'd brought a change of pants. "High stakes, huh?. ”He kept silent.Me: “Are you turned on by watching me naked?” I asked in shock.He: “I don’t know I can’t help it he said”Me: “Well try I am your sister.”He threw the bed-sheet on bed and came closer to meHe: “I know but…..”Me: “but! But what?”He: “But you are so hot and sexy and not to mention clean and smooth.”Well I didn’t wanted to hear that but that words of him though felt a little good as all the time I was in his apartment all I thought I did was lose my dignity little by little.Me:. . “Who do you belong to, lovely? Tell me…who can make you cum with just his voice, without even touching you? Who has you so aroused right now and always does, to the point that you can’t think straight?” As he kept at that agonizing slow, strong pace. “You…” She gasped, thrusting back against him, arching deeply, releasing a lusty moan from her chest. “And who am I , my beauty?” He thrust deeper and harder…but still slow. “My… Master…” She groaned, pushing back against him, her back arched.. We sat and just talked to each other. I then got up and went to the kitchen and grab us both a glass of wine and a blanket. I handed her a glass of wine and layer down a blanket in front of the fireplace. We laid and drank wine together just looking and feeling the warmth of the fire. I leaned over to kiss her. In doing so I wrapped my arm around her embracing her body up against mine. I held her tightly not wanting to let her go. I went from kissing her lips to her neck. I pulled off her shirt.
