In my mind, I cursed that fellow but then I saw she is coming back to the location where she was. Once she reached near me I felt I should try again b...t if I do it immediately she may suspect hence planned to do it after 5 mins.After 5 mins, I again did the same thing and this time she was there so when I picked the eraser slowly I touched her right thigh area. She turned towards me but when she saw me, I was picking the eraser and did not touch her intentionally, she went back to monitoring. You better get cleaned up. Mom's probably almost done packing for Aunt Karen's." Her large tits jiggled invitingly through her blue halter as she jumped up from her knees and stepped out of my room and into the hall.I pulled my pants up, buttoned them, and buckled my belt.
