My sister who is a stuck-up hottie slipped into my room two weeks ago, pulled off her t-shirt and p****** and asked me to make love to her. I’m 18 and she is almost 17. I made love to her obvious virgin body for over an hour. She swore me to secrecy and left. It was totally awesome except that we ruined my beds bottom sheet. The next morning she was her usual bitchy self. Two mornings later she was up before me and cooking us breakfast?!! She was sorry that she had used me?? Her boyfriend didn’t DO virgins?!? He was a total pig when they did IT?!? So now she wanted to be nicer to me after 6 or 7 years of living hell?!? I quickly turned her into my submissive s** toy and slave for my chores. I came in her mouth only an hour ago. She seems really happy now and is actually nice to people! Even our parents have noticed a big change in her.
