The first time I met her sister, she seemed to be a current J-style model with a tall, slender, and irresistible body. When I asked my sister to show me the swimsuit she was asked to wear for work, it was unexpectedly an extreme high-cut swimsuit...! I was overcome with the urge to see her wearing it. I secretly entered the house and peeked at her trying it on, but my dick got irritated because just watching wasn't enough! I tricked her into saying it was a shooting and posing practice, had her straddle my lower body, and brought her to a bare-skin state! When I had her do a high-cut bare-skin just for the promise of cosplaying, her undeveloped sensitive pussy started to get wet, so I immediately raw inserted! I creampied my shyly cumming sister many times after inserting into her pussy, which was teased with persistent bare-skin sex!
