My curiosity drawing me to the door, I peered inside and was greated to Mark sprawled stark bollock naked on the bed and Sam sucking his hard cock. I ...atched as Sam licked his shaft and head not missing anywhere, Mark was groaning as she bobbed her head up and down , her free hand groping his ball bag! My cock was so rigid it almost hurt, i pulled my cock out and began wanking myself off as sam expertly sucked his cock.I began to wank my cock harder and using my free hand to play with my balls. I eventually got two cups of ice cream and walked back slowly to give myself a chance to size her up. She was still sitting on the bench gazing off in the opposite direction, lightly bouncing her crossed leg, brown wavy hair flowing, looking lonely and... alluring. And that was that. Something came over me, a strong desire for this girl, my sister, this wonderful feminine creature. No. Noooooo!We ate our ice cream in silence. When she looked away, my eyes found their way to her legs, uncrossed. "Man, wait until you get a look at her." Who is she?" Pete started down the ladder."Her name's Viv Lanier. She said she's from Reno, that's all."Reaching the ground floor of the barn, Pete faced his brother. "And she asked for me?" Yep."Pete headed out of the barn. Cal started to accompany him.Pete stopped. "I'm the one she asked for. Knock down some more of that hay, why don't you?" Aw, for Christ's sake!" Cal grumbled, but he turned to the task.As Pete approached the car he saw the reason for. I had shopped there several times and the middle aged assistant who wasnormally there was very helpful when I was buying 'something for mywife'. Now whether she knew what I was buying was for me or not, shenever made any comment or even a hint suggesting anything was anythingbut totally normal and that suited me fine. Some cross dressers I talkto love to say they were shopping for themselves but I felt this was fartoo personal to share in that way.As I went into the department she looked up.
