Missy got straight A's, but so did kids of average ability. Some of her teachers knew she was an outstanding student, but in the non competitive atmo...phere we encourage, this wasn't easily discernable. Her scores on the PSAT, the highest in the school, had surprised some in the administration, including, I think, the principal. He had apparently known almost nothing about her, his brightest tenth grade student. He didn't even know I was her grandfather, not her father. I've often wondered. Last night (Friday) I thought I’d have the house to myself as Kip was going to spend the weekend down in Denver. On Friday morning Kip asked me if it was OK, if some friends of his crashed here, of course it was OK with me, it is his house and I’m a guest. Kip said the couple, Jeff and Stephanie, are long time friends and were coming up after work to go skiing on Saturday morning.So, last night, I was just doing some work and having a Jack and coke when Jeff and Stephanie arrived just before. I grab her waist and pull her back. Then I guide myself to her entrance. I hesitate, but when she doesnt object, I press into her. I pull out before even getting halfway in. I line up again, then I thrust all the way in. Uh&hellip,Uh&hellip,Ahh, she moans loudly as I glide in. Slowly, I begin moving back and forth, sliding in and out. Her moans begin coming regularly and heavy. I grunt occasionally as her pussy tightens and grips my cock. Ahh, fuck. Shit this is good. I begin picking up speed. She had on only small earrings, nothing more and her make up consisted of a dark blue eye shadow that made her baby blue eyes somehow shine, mascara, and lipstick."Okay? Sam you..." Thia's smile faded the moment he said her real name, "Ah... I mean Thia, you look fantastic."She smiled again but still felt bad, she didn't want him to like the way the old Sam looked. That's not her now, and if they made her choose again she wouldn't go back to her old self. After that day at Ally's Shane had done.
