"Your sister is sexy," she said as her only explanation. Brian looked back at his sister, who was pumping her hips to the music as she continued to rub her pussy and squeeze her bare breast. Holly turned around again and bent over, shaking her ass for a second then putting her fingers under her thong, acting like she was going to pull it off. Then she stood back up, turned around and slipped her hand back onto her thong covered pussy.
"If you touch yourself, I'll take the rest off," she said as she lowered down to a squat, her legs wide apart and her thong so stretched her hand was doing more covering than the think pink fabric was. Holly smiled and bobbed up and down to the great even as she kept touching herself. Brian didn't hesitate any longer as he slipped his hand in his pants and began stroking himself. Holly and Hellen laughed.
"Oh baby that was perfect!" Hellen said proudly. This all seemed to satisfy his sister, who stood up and turned around, facing her ass out once again. She dropped to the floor, bobbing her ass up and down again to the beat, both teasing her brother and mother and working up the guts to get completely naked. She stood up and walked right up to Brian, bending over in front of him and shaking her ass, her sexy end bobbing up and down, Taking a few steps over she did the same thing in front of her mother, who immediately put her hands on each of Holly's sexy cheeks as her daughter swayed her hips. Brian watched in amazement as his mother generously squeezed her daughter's ass.
"Can I do that?" he asked before he even realized he was speaking. Holly as back over in a flash, shaking her gorgeous ass up and down for her brother. Hardly believing he was doing it, Brian slowly put his hands on Holly's curvy, smooth ass, and knew it was the best thing he'd ever felt. He squeezed and squeezed, not wanting to let go, and after what felt like a few seconds, Holly stepped forward and away, leaving them to watch again, both mother and son going back to touching themselves without even thinking about it. There was not to a lasting disappointment at Holly moving away form them, because as she leaned over and slipped her fingers under her thong once more, Brian became sure that she was going to take it off at last, and he would see her bare sexy ass.
Slowly, slowly, slowly, Holly pulled the thong down her ass, revealing her sexy bare crack more and more. At last, with one final tug, Holly had pulled her thong off, and was standing leaned over with her bare naked ass pointing right at her waiting brother and mother. She slipped her thong off and then immediately grabbed her cheeks and pulled them apart, revealing every secret part of her sexy round ass. She even put one finger in her mouth and ran it up her bare naked crack. She swayed her bare naked ass back and forth a few times before running hands over her ass again and spreading her cheeks. She then turned around and lifted one foot up onto the couch between her brother's legs, showing off her beautiful, tasty bare pussy, and began openly rubbing her fingers between her lips Brian could hardly believe that his mother and sister had encouraged him to watch Holly striptease completely naked, but he knew, as the song came to an end, if nothing else happened, this was the best birthday present he'd ever received.
To his everlasting pleasure, this was only the start.
Holly walked up to Brian, sat down on his lap, and began making out with him. Brian had no complaints now, happy to put his hands on his sister's naked ass and leg, enjoying her passionate kissing. He ran his hand up her long sexy leg and onto her flat tummy, then cupping her breast he began squeezing, thrilled at how good it felt to touch a woman's breast. He leaned forward and kissed Holly's breasts, moving straight to her nipples where he sucked hard and licked eagerly. She sighed with pleasure, pressing her breasts forward into her brother's face to give him better access. Brian pulled Holly forward, pushing his hard dick that was still under his shorts against his sister's sexy athletic legs, and was stimulated even more. She had been sitting across his lap, but now she swung her leg over so she was riding him, one leg on heath side and close enough so she could rub her wet, hot pussy against his hard dick. She did so eagerly as they went back to making out and Brian ran his hands all over Holly's naked body. With his hands on her ass, two wonderful handfuls of sweet sisterly booty, Holly leaned back so her amazing tits were perfect to suck on, which he did with great excitement. He took his time, enjoying himself as he traced the outlines of her nipples and ran his fingers lightly over her legs and down between them, and after many minutes Holly began pushing him forward. She grabbed the edge of his shorts and pulled them down, giving Brian the clue that she was wanting more, namely his dick inside of her.
Dan pulled his shorts and boxers off quickly, his hard cock popping out and ready for anything. Holly got off his lap and onto her knees, where she grabbed his dick and put it in her mouth, sucking hard and using her tongue to play with the tip of his cock. It was incredible to look down and see his sister sucking on his dick, and Brian almost came right there, but managed to speak up.
"I'm going to come," he said breathing heavily.
"Not yet, you have to be inside of me silly," Holly said excitedly, standing up and climbing onto her brother. She grabbed his dick and guided him in, sliding down onto her brother, pushing herself up and down on him immediately. Brian pumped his dick up into his sister, thrusting hard and soon releasing, pumping cum into his sweet and sexy sister's body. His breathing was fast and he heaved his body deeper inside of her, making her come as well, both siblings riding each other hard. After a few minutes they both breathed easier, and smiled, looking into each other's eyes with deep affection and love, and they started kissing, Brian still inside his sister.
"I'm sorry to break this up, but I'm going to need your sister," Hellen said with a supportive laugh. Brian pulled out of Holly as she stood up, and he gave her ass loving squeezes while Hellen handed Holly a wash cloth to wipe her brother's cum off as it seeped out of her vagina. Biran couldn't believe what an amazing birthday it had turned into.
"Now don't worry Brian, you'll get her back, and you'll have even more fun. I think we need to do something to get this guy working again," his mother said, walking up to him and tenderly touching her son's deflated dick. "And we know just the trick, don't we Holly?"
"Oh yeah! I can't wait!" Holly said excitedly, standing beautiful and naked in front of her brother and mother.
"We'll be right back, but don't go anywhere!" Hellen said as they left the room. Dan had to laugh, thinking that nothing could get him from that room unless it was death itself. He didn't' have to wait long, and soon heard a more upbeat, club song paying on the living room speakers. Holly ran in and jumped on the couch, wearing tiny black shorts and a zip up hoodie, and immediately began rocking her hips to the music, feeling up her tits. Hellen sauntered in, wearing a matching outfit, and got on the couch as well, stepping right up to her daughter and began pumping her hips back and forth as well, but she was looking seductively at her daughter and directing her actions towards her. She took Holly's hand and turned around, and then bent over, shaking her ass. At the same time Holly moved in behind her mother and started grinding against her mom, putting her hands on her hips and pressing herself right against Hellen's sexy ass.
Brian was in shock, his eyes wide and mouth hanging open, as they danced erotically in unison together, holding hands as they stood up and bumping and grinding still. Their hips swayed from side to side as they giggled and danced. They got lower and lower, their legs spreading open and still Holly had her pussy pressed right against Hellen's ass. As they stood back up, Brian watched his mom playfully start to pull the zipper down, and he could just see her bra when she turned around. Holly however was facing him as she danced and unzipped, leaning over so her cleavage was on display, feeling between her legs. Hellen started to take the hoodie off, then they both turned to face each other. Brian gave a little gasp when his mom ran her hands over Holly's chest, cupping her breasts as her daughter pulled her hoodie off. Brian's mom had hers off too, and he watched as his sister and mother danced closer and closer, wearing only shorts and a bra, their bodies pressing together.
