The next day both Clay and Sonja's parents and Michelle were all scheduled to leave. By sheer coincidence they had all booked flights within the same 2 hour period. So Clay, his parents and Damon took his SUV, Sonja, her parents and Michelle took her car, and Amy, Bridgette and Denise took Amy's car and they all headed to the airport. Goodbyes were exchanged and they all split up long enough to make sure everyone got where they were supposed to go before meeting back up and heading home.
"Hey mom," Bridgette said as they walked back to the parking garage. "Can I borrow the car? Denise and I need to go shopping."
"Need or want?" Amy asked.
Bridgette and Denise looked at each other.
"Both?" Bridgette asked.
"Both is good." Denise said.
Bridgette looked back to her mother, "Both."
"Sure honey," Amy said, laughing, "Just drop me off at home."
"That reminds me dad," Damon said to his father, "Could you drop me off at Sam's, since it's on the way?"
"Tell you what," Clay said, handing Damon his keys, "Take the SUV and I'll go home with Sonja."
"You mean we'll have the whole house to ourselves?" Sonja asked, with a fake gasp. "Whatever will we do with ourselves?"
"Whatever it is, we don't want to know." Amy said, making a sour face, causing everyone to laugh.
"Hopefully you'll pack," Damon said, "Considering you're leaving for your honeymoon tomorrow."
"Great," Sonja mumbled, "That reminds me I need to do my laundry. Thanks a lot Damon."
"You're welcome... mom." Damon said, throwing her a cheesy grin.
She took a good natured swat at him, but Damon easily avoided it.
The rest of the day passed without incident. Damon spent the day with his friends, Bridgette and Denise went shopping, Amy was in a zoom meeting with her co-hosts working on material for the next episode of their YouTube show and Clay and Sonja did their laundry and packed.
The next day Damon and Denise drove their parents to the airport to see them off on their honeymoon.
"Now you have the number for the hotel, there's plenty of food in the fridge..." Clay said.
Damon grabbed his father by the shoulders, "Dad, it's okay, we'll be fine. I'm not 12 anymore. If there's an emergency we'll call aunt Amy."
"Unless it's the end of the world, we won't bother you." Denise added, "We're old enough to take care of ourselves. Now go. Enjoy yourselves."
"They're right, dear," Sonja said, pulling on Clay's arm, "Let's go."
As they exchanged hugs Sonja leaned in close and whispered to Damon, "Take good care of my daughter."
He gave her a shocked and confused look but she just smiled and kissed him on the cheek.
Damon and Denise watched as their parents got in line for the TSA checkpoint and headed out of the airport. As they walked through the parking garage, Damon looked at Denise and smiled. "Your room or mine?"
"Yours is closer to the stairs." Denise said.
As soon as they got back to the house they raced up the stairs to Damon's room and practically ripped their clothes off as soon as they hit the landing. They fell into Damon's bed wrapped in each other's arms, their lips locked in a passionate kiss. Damon's cock was as hard as it had ever been, and Denise's pussy was soaking wet. They had the whole house to themselves for two weeks, and they were going to take full advantage of it.
Of course Damon still had no idea about Denise and Bridgette, or Denise and his father, and Denise had no idea about Damon and her mother, Amy or Michelle. All they both knew was that Damon was sinking all eight and half inches of his cock into Denise's eager pussy. She looked up at him with a lusty smile on her face.
"Fuck me big brother," she moaned, "Fuck the shit out of me!"
"If you insist." Damon said, and started doing just that.
He started hammering Denise as hard and fast as he could. For the first time since they had met just a week earlier they could finally be as loud and wild as they wanted. Denise was screaming and groaning in pleasure and Damon was grunting with the effort as he mercilessly hammered his cock into Denise. The bed squeaked underneath them, the slap of flesh as their hips met, the banging of the headboard against the wall, and their moans of sexual satisfaction filled every room in the house as they fucked like two wild animals in heat. Little did either of them know this was the very same room Clay and Amy first had sex in when they started their brother/sister incestous relationship years earlier.
"God your cock feels so goddamn good inside my fucking cunt," Denise growled, digging her nails into his back and wrapping her legs around his pumping hips.
"It's so much better now that we don't have to hide it," he grunted, "I've been waiting all week to fuck you like this."
"Me too," she moaned, "You're the best brother a girl could ask for."
He leaned down and kissed her, never stopping his hips from driving his cock deep inside her.
"I wish we could stay like this forever," she moaned, "Just fucking all day, every day."
"Well we got two weeks," Damon said, "And I plan to fuck you every single day."
"You'd better." Denise moaned. "Now flip over, I wanna ride that magnificent cock of yours."
Damon thrust deep inside her and rolled them over, keeping his dick buried in her. Once he was on his back, Denise sat up on her knees, clenching her cunt around his cock. They were both already covered in sweat, but they didn't care. They looked into each other's eyes and smiled. Denise braced herself on Damon's chest and started riding his cock, slowly at first, but rapidly picking up the pace, until she was bouncing up and down on his cock as fast as she could.
Damon watched her sweaty tits bounce around on her chest and reached up to grab and pinch her hard little nipples. Denise bit her lip and looked down at him, moaning in appreciation of what he was doing. She leaned forward so Damon could suck on her tits, and he eagerly took first one tit, then the other into his mouth. Then much like he had with his aunt a couple of days earlier, he pushed her tits together so her nipples were almost touching and sucked both of them into his mouth at the same time.
Denise squealed in pleasure and looked down at Damon wide eyed.
"Holy shit," she gasped, "What the fuck? No one's ever done that to me before."
"What about this?" Damon said, grabbing her hips, and much like he did with Sonja a few days earlier, he started controlling the pace, moving her up and down on his cock. Then he held her in place and hammered his cock up into her, causing her to first squeal and then scream in pleasure as she felt Damon's cock go deep inside her as he suddenly stopped and pulled her all the way down on his cock. She looked down at him, a look of shock on her face as she could feel Damon's cock throbbing inside her despite the fact that they weren't moving. He was just grinning at her.
"What the fuck are you doing to me?" she asked, brushing her purple hair out of her face.
"You like that?" he asked, wiggling his eyebrows.
