Not only are you super hot, but you are super sweet as well. Thanks again, Susan." "Aww, thank you, Zack. It was my pleasure. I really had a great tim... with you, Seth and Bobby." He slid a folded napkin to Susan as he walked away. "Looks like you have a secret admirer or three," I said sarcastically. "Yeah, I wonder what this is all about," Susan said as she unfolded the napkin. As she read it I saw her eyes open wide. She smiled as she read it. She looked towards the guys. They were all. We have a pool in our back yard and sometimes during the day when he is at work, she might be out there on her float topless.On day back in early summer, he came home from work early and caught her out there and she could not get out and get her bikini top on the deck before he got a good look at her.That's when the flirting started and he loves catching her in the yard when I'm not around, so rather than being rude, she will talk with him there at the fence for awhile.The flirting started. .I just mumbled...he came closer...he sk** his heel under my jeans covered balls. I was very aroused...I felt his legs and they were silky smooth...his cock was right in my face...he guided it to my mouth...I took it in...tasty...I was touching his heels...the coolness of the leather was heavenly. He began to pump faster..I was really enjoying...tasting his thick precum. Before long he began to moan and his thrusts increased. I knew he was close so I doubled down and sucked harder and was soon. "It's OK Sara. I kind of liked knowing you were watching us. We both did, actually." Dad knows! Oh my God, I'm so embarrassed." Don't be. He was actually pretty turned on by the whole thing. It was actually his idea to rent this boat and go to the island. Could be kind of fun," she said coyly as she winked and slipped a finger into the bottom of her mouth. She leaned over close to me and whispered, "Besides, you saw me fucking your father...I want to watch you fuck your brother. It's only.
