Fuck half sister

You go to you half sisters house and wait for her to return from school. Finally she returns and as she enters her room you immediately use the watch on her, freezing her. You look at her young tight eighteen year old body. Walking behind her you pull down her jeans and cotton panties. Pulling out your cock you slip it up inside of her and thrust until you cum inside of her. Putting youself away you put her cloths back on and start time again.
