My knees became very weak and I almost fell to the floor. Somehow I stabilized myself but shook noticeably.This stunned Mom and she froze, not knowing...what to say. The smile came off her face as she looked down, pretending that she was noticing for the first time that I was in her panties. I felt very shameful as she looked at me, and as I looked down at the floor in shame I realized I still had quite an erection poking out from the front of her panties. This deeply embarrassed us both but I. She was a water-skier and had smooth, muscular, but not too muscular legs that saw their share of sunlight. Her cute brown feet were in white flip-flops, the kind that has the really thin stringy thongs which showed off her cute feet. I got an instant hard-on. She pulled me to my feet where the group was sitting in the sand. We hadn't begun to ski yet so she told the group she was going to warm up the boat and get used to driving it by taking it around the lake once. She of course called me to. “Do you see anything you like?” she asked.“Yeah,” I replied.April stepped backwards and sat on my lap. As she did, she slipped her hand around to the base of my neck and whispered,“Is that a cucumber I feel, or are you kind of happy to see me?”I chuckled.“I don’t think it’s a cucumber,” I breathlessly replied. April shifted her weight, as she grabbed my hands and placed them on to her thighs and between her parted legs. She pushed my fingers towards her womanhood.“You know what I’d really. Oh yea, this is going to be a hot one, I know. My heart speeds up and my breathing comes faster. Her command is barely uttered before I've stripped naked."Here, put your gear on while I watch," Julie orders as she hands me The Lasso and Love Leash. I quickly slip the Lasso over my balls and cinch it around my sac. My balls are now presented nicely for Julie's inspection. She cups them and tightens the Lasso just a bit more. "I want to make sure those puppies don't slide up and hide on me," she.
