Check Sam's bedroom

As Sam walks over to the door he hears a quiet whimper coming from inside, followed by a sharp moan. Slowly turning the handle he eases the door open to peek in and freezes as he sees Joe and Phina, their bodies entwined, Joe’s cock buried in Phina’s mouth as he attacked her pussy with his tongue. Both so engrossed in what they were doing they didn’t notice Sam at the door staring at their show of incestuous passion.

Not sure what to do, Sam began to slowly close the door, trying desperately to not make a sound or alert them to his presence. Freezing again as he felt hot breath on the back of his neck, and a hand snake around his waist.

“They are really enjoying themselves, aren’t they,” Emma whispered in his ear?

Her hand slid into his swimming trunks to wrap around his engorged cock. Gripping it hard and then beginning to slowly stroke it.

“I think you're enjoying them too,” she whispered before nibbling on his ear.

Sam turned to look at her and before he could speak their lips met, her hot tongue forcing its way into his mouth, her body pressing against his as she continues to jerk him off. For a moment he tried to fight it, but the constant display of female flesh over the course of the day, the flirting, and the site of Shelly taking James’s cock between her beautiful lips only a short while ago had all finally broken down his resistance.

He broke the and with his forehead pressed against her let out a gasp of pleasure.

“Fuck, I want you so bad,” He growled.

Emma laughed, and then sank to her knees in front of him, pulling down his trunks as she went. His cock bounced out, nearly hitting her in the nose. She giggled at that and then caught it with her lips, sucking him into her mouth for a moment, then pulling back and licking it from the tip all the way to his balls.

“You keep an eye on my children while I enjoy this delicious treat,” she cooed as she looked up at him and then began to lick and nibble on his dick.

Sam moaned as she took him back into her mouth, her lips sliding up and down his length as her tongue danced across his flesh. Tearing his eyes away to glance into the room Joe and Phina had changed positions, Phina laying back on the bed with Joe’s cock moving like a rapid fire piston into his sister’s beautiful little pussy.

It took Sam a moment to realize that Phina was staring right at him, as their eyes met she smiled and then licked her lips. He glanced down is fear, then realized the position of the door hid Emma from sight. With his hand on her head, and the movement of his body as she sucked his cock he probably looked like he was just vigorously jerking off.

Phina blew him a kiss, and then reached up and pulled her brother down into his arms, kissing him as he fucked her.

Sam could see their bodies tensing as they reached orgasm, his own body doing the same as Emma’s ministrations brought him to the edge. Suddenly, Phina’s body arched upward, her entire body shaking as she came. Joe jerked backward and out of his sister, then began shooting his load across her stomach at the exact moment Sam began to fire his own into Emma’s hungry mouth.

Emma pulled off his dick with an audible pop, and smiled and licked her lips as she looked up at him.

“That was delicio. . .,” her words were interrupted by the sound of Mike yelling up the stairs.

“What the hell are you all doing up there. Lunch is on the table, do I have to come get you myself,” he roared.

Everyone froze as they heard him begin climbing the stairs.
