Tim rubs her cheeks some as he asks, “Abigail, why are you being spanked tonight?” Abbie tears now filling her eyes already, in anticipation of h...r having to confess her sins.Abbie hesitantly replies, “I was very bad, getting involved with gossip which I should be stopping, not adding to. And treating staff members without respect and in full view of others. Now I will be spanked every week as a reminder to be good. And for any minor or major misconduct, I have committed during the past. Although I was not a smoker my self the thought of Emma smoking really turned me on. Watching those sexy lips sucking on the cig and then blowing gently out... I felt my cock getting hard again!I quickly opened the door and there sat in the corner on an old chair was Emma.

We still had not spoken to each other other than generic conversation whenever our parents were around. Around 12, everyone went to their rooms.There were 4 bedrooms, one each for her parents and.

When she got almost to the top step, she started fumbling boxes. That's when I noticed she wasn't wearing any panties. My heart started pounding, as I stared at the thickest white ass I had ever seen. To me her ass was perfect, just how I had imagined.
