Alex

Luke quickly pushed the door open and stepped inside closing the door behind him in one swift motion. All the while still stroking his cock with just seconds before cumming.

"What the hell are you doing?" Yelled Alex breathing heavy and clearly short of breath. Luke froze. Alex nearly jumped off the bed she sat up so fast. Her hair was a mess and her cheeks were flushed.

Luke had completely forgotten Alex shared a room with Haley. Luke was speechless. He was a deer in the headlights stroking his dick. He hadn't even thought to cover himself up. He just stood there, dick in hand, in front of his sister.

"Oh my God!" Cried Alex. "Were you gonna jerk off in here?"

"What? No," stammered Luke coming back to reality. He pushed his still hard dick into his shorts. His hardon still clear in his athletic gym shorts.

"Yes, you were. You had your dick out and you were jacking off," accused Alex. "And you still have a boner!"

"No, it's not like that," said Luke floundering. He couldn't think straight. He had given himself blue balls and was caught by his sister at the same time.

"Then what is it like?" Demanded Alex standing up from the bed. Luke's eyes went wide as he immediately noticed Alex wasn't wearing any bottoms, at all. Her thick, soft white legs leading the whole way up to her crotch. Luke followed the trail to her pussy and felt his penis throb. He was so horny right now. He wanted to fuck Alex. She had the biggest tits in the family and a nice big ass too. Her glasses and nerdiness only made her hotter. Luke forgot about his plan to cum on something of Haley's. Now he wanted to cum all over or inside Alex. He stared directly at her pussy hoping the image would be burned into his mind forever.

Alex's pussy wasn't shaven bare like his mother's, but it was trimmed. It looked like she cut back her dark brown bush so it didn't become overly hairy which somehow turned Luke on even more. He had seen enough shaven pussies on the Internet, but most importantly he had never seen Alex's. He was getting an eyeful right now.

Alex noticed his staring, but before Luke could say anything Alex....
