サキュバス☆ルゥの中出し魔力補給♪

Tsuyoshi is busily studying away for his exams. Then one day on a rare walk to the park, he gets captured by a hungry succubus named Ruu.

"Let's have some dick-in-pussy fun~ Since it's a first for us both, it'll definitely be a lot of fun!"

That's right, Tsuyoshi's attacker was a virgin... and a princess!

Eventually, however, Ruu snaps out of her intense hunger and apologizes. Even so, she fell in love at first sight , and wanted to train under him. Despite being a princess, she was still inexperienced, after all.
