Lolicon hentai with orgy

So basically i remember that it's old, i saw it when i was discovering hentai. The main girl is a short blond loli that invites the protagonist to her house for an orgy. When he goes rhere they are already at it with multiple girls compiting for being the most popular. But i remember it was all actually a plan for the main girl to do it with the protagonist, she was in love with him but too shy to tell him, so she wanted to use the orgy as an excuse to be with him lol.
