Turning the brightest shade of red you have ever seen, Yoji Drinks in his twin sister with his eyes. His pants instantly tighten.  "Why was Ryu in here" he thought to himself, but not for long.  Sounds of foot steps behind his didn't warn him quick enough, His big sister rushes in and stands there telling Yuuki to put some clothes on.<br/><br/>"You need to be nicer!" Yoji says quietly "And who are you to talk, I can see your nipples through that shirt... ever heard of a bra! You probably arn't even wearing underwear!" he was getting loud now, he didn't like it when people yelled at his twin.<br/><br/>"Yuuki is beautiful and you are jelious!" was the last thing Yoji said before realizing what just came out of his mouth.  Realizing his cock was pushing his pants outward he quickly pulls his bag off his shoulder and holds it in front of himself.<br/><br/>"I'm sorry sis, I didn't mean that..." Yoji bows his head down in shame for yelling at his older sister. But still keeping one eye on his naked twin.
