This a rather rare video for S1, a huge harem is very far from what they usually do. A special video celebrates its 15th anniversary.

The line up was stunning and it included Yua Mikami as flagship S1 girl. But some important S1 girls that were on their roster at that time were missing.

It is an amusing video and to see them all together, but the sex scenes are rather bland. Regardless, it’s worth the watch.
