I could see the head of his cock covered in pre-cum even though he hadn't touched himself. I squeezed the head of his cock and wiped his pre-cum on hi... fingers, and fed it to him. He licked my fingers clean of his pre-cum, and moaned. What a good boy.I was getting ready to go down and lick his boy clit, but as I did, he grabbed his legs and pulled his knees up behind his head. I got the hint. He wanted his taint licked. And that's just what he got! I started out lightly going over it with my. I lost count of how many times I came but my pussy and sheets were soaked with my juices and cum. It turned out to be a new experience and great fun for me and I think for everyone else as well.

Jumping ahead one week, I get a call from the first guy asking if I wanted to meet him. I agreed, and after work that day there started a routine of sexual attention any woman could only. I pulled into the driveway and only my sister's care was there.I opened the door and yelled hello. No one answered but I heard the shower going. I went upstairs, I guess deep down I was hoping to catch one more glimpse of my sister's perfect b cup tits and freshly shaved pussy.

Talk about crippled.”I nodded. Truth is, I too had forgotten how to subtract due to my using calculators so often. I started forcing myself to add and subtract manually so my brain would remember the process. Now I’m working on my multiplication tables. Next it’ll be multiplying and dividing fractions. Technology is handy, but it’s also a dangerous crutch.
