She whispered to me “I”ve never seen anything like this before, it”s so big, I don’t know if I can fit it all in my mouth. Then began to gentl... stroke the shaft of my dick, and slowly started to lick my head. Quietly, she began to suck on my tip, sticking it deeper and deeper into her throat with every bob. The pleasure I experienced at that moment was off the scale, having my sister suck on my dick was too intense to even begin to describe. I was rock hard, dangerously hard to be honest with. "Oh yes!" Laura replied. "I think he's just as excited about this as I am." That's good," Janet replied feeling more confident than ever that this couple was going to work out like a dream. "And like I told you earlier, Francis is definitely one of THE best studs Mike and I have ever worked with over the years. And," she added, and pausing for effect, she added: "he's got really, really nice and BIG cock. He's extremely good at using it, too!" Your making excited!" Laura said.As she and Janet. She was just sitting upon the bench when she heard feet on the tiled hall. An older man walked in and nodded to Kathryn in greeting. His eyes widened slowly and he seemed to take a second more careful look at her. Kathryn smiled and anxiously turned her head hoping he would go about his business. He did not. "Excuse me miss." His voice seemed loud in the silence of the museum as he walked closer. "Excuse me," he started again as Kathryn slowly turned to acknowledge him. "Ahhhhh yes, I see." He. Just as I got fully hard again, I heard a light tap on the door. I opened it up just a crack and leaned around it to see what was up. I knew who it was from the fact that she knocked and didnt just walk in like Rachel would. This might be bad, I was naked, she was fifteen, and her mom was downstairs. Whatcha doin? she asked playfully. You need to go back to your bedroom before we get caught! I said in a hushed whisper. Oh come on, Mom is downstairs and you know shes not coming up for at least.
