Flare fights Lobelia, but ends up having a hard time. - Just when she was about to receive the final blow, her older brother, Brother Shine, burst in and attacked Lobelia. - The two brothers repel Lobelia with their combined skills. - However, immediately after, Shine is swallowed by a warp hole and abducted. - Shine is brought to an unknown ruin by a warp hole. - Just then, Lobelia, who was supposed to have been defeated, appears. - The Lobelia I defeated earlier was just a copy. - Shine confronts Lobelia again, but is restrained and electrocuted. - ``You're going to be my guinea pig,'' he says, and Lobelia injects him with an experimental drug and gropes his crotch. - ``Now, I have to reward you, naughty guinea pig, right?'' Shine desperately resists the stimulation of Lobelia's hand job and blowjob, but he succumbs to Lobelia's t** and begs to be Lobelia's guinea pig himself, and falls. - I end up doing it. - "...The experiment was a success. We got some good data. Hehe, there's just one more person left..." Lobelia laughs mysteriously. - Another experiment by the evil female scientist is about to begin... [Female Scientist HAPPY END]
