Haley walks in

Haley slowly pushed the door open and stood there shocked at what she had just watched. She couldn't believe it. Alex just sucked Luke's cock and made him cum all over her.

"Oh God, Haley," Luke's voice cracked as he shot up on the bed stricken with terror. His eyes widened with the realization that they had been caught and they were screwed. Haley slowed stepped into the bedroom. She was still only wearing the red thong and white tank top.

"It's not what it looks like," cried Alex jumping to her feet. Her tits bounced underneath her shirt. Her pussy was still showing. Haley immediately noticed her sister's bush and wet pussy.

"Really?" Said Haley looking from Alex's cum coated face to her pussy to Luke's deflated cock. "Cuz, it looks like I caught my SISTER sucking my BROTHER'S dick."

"Please, don't tell mom and dad," begged Luke standing from the bed. His soft dick dangling down as he walked around it to stand next to Alex. Both siblings stood in silence waiting for their older sister's judgement.

"This is so fucked up, you guys. I can't believe actually sucked his dick, Alex," said Haley looking down at Luke's dick. Alex looked at the floor embarrassed. She still hadn't wiped the cum from her face.

"Well, he was going to jerk off and cum on your pillow," cried Alex looking up at Haley. "So I did you a favor."

"What?!" Yelled Haley.

"Alex," yelled Luke tackling Alex onto the bedroom floor.

Luke landed on top of her between her legs. They wrestled, but Luke managed to stay on top. His dick rubbed all over Alex's pussy. To Haley, it looked like the siblings were having sex and it really turned her on. She wished she would have actually seen Alex sucking his dick. Not just catching the absolute end.

"Hey, stop it, you two," yelled Haley as she slapped Luke on the ass. They stopped almost immediately, but Luke stayed on top of Alex. A weird look crept over Alex's face.

"Luke, are you hard?" Asked Alex. Luke thought for a moment.

"Yeah, I think I am," answered Luke.

"Jesus Christ! Get off!" Yelled Alex rolling over throwing Luke off of her. It was true. Luke was fully erect again. Haley couldn't take her eyes off of his hard cock. She felt her pussy moisten with the idea of fucking him. She wanted to straddle that cock and slide it all the way inside on the first go letting it stretch her and then riding him until he came inside her.

"Well, I was trying to get off, but you quit too soon," said Luke.

"I, I, I can't do this," said Haley knowing her thoughts were wrong. She turned to leave the room.

"Wait, don't tell mom and dad!" Cried Alex still on the floor with her legs spread. Her hairy pussy was still on view to Haley.

"Oh I'm telling them. You two need therapy!" Said Haley over her shoulder.

"Wait, we'll do anything begged Alex standing up. Haley stopped and closed the door with a smile that neither Luke nor Alex could see.
