Gabe was drunk off his ass. He'd arrived at Ronnie's house, his best friend, a couple hours before everyone else came and they had the smart idea to pregame the pregame. His twin sister Brooke had come to the actual pregame with plenty of cocktail ingredients and he downed drink after drink, amazed at how he couldn't even taste any alcohol. Then at the bar, he'd met a cute asian girl celebrating her birthday, and like the gentleman he was, he had to buy her some drinks. Of course he couldn't let her drink them unaccompanied so he had a couple more alongside her. Though he managed to cop a feel over her tight white jeans and got a nice handful over her spaghetti strap crop top, he didn't go home with her. Instead, he found himself back at Ronnie's, their group dwindling down to the two guys, his sister, and two more girls, Vanessa and Melanie.
The whole group had plenty to drink, the stench of alcohol emenating from all of them. They sat in a circle and were in the middle of a game of Truth or Dare, though they came up with a new rule where they had to take a shot if they picked truth, which explained why Vanessa and Melanie already had their shirts off. They sat there both in simple lace bras, Vanessa's double Ds held up by a white one while Melanies perky Bs were held in a pink one.
"I don't know what else I expected, letting you two be the first ones to go", Brooke said, shaking her head at the two boys, drunkenly smiling and unashamedly looking back and forth between Vanessa and Melanie.
"Well since it's my turn, Gabe, truth or dare?"
Brooke had to repeat herself to get his attention, too entraptured by the way Vanessa's tits bounced around when she got up to get herself another drink.
"Dare obviously"
"Put on Vanessa's top and send a pic in our family group chat"
"Psh easy," he said, eager to take off his top and show his muscles to the girl. He'd been hitting the gym during college, at first to try and pickup girls, but instead found a group of guys as gym buddies and began really enjoying his workouts. Ronnie was one of those buddies. He went religiously with him and his hard work had paid off.
Even Brooke had to appreciate his chiseled muscles, happy that she would get photo evidence that would come in handy later when she was alone in bed.
"My turn?" Vanessa exclaimed, eager to get the game moving.
"Ok then, Brooke I dare you to-"
Melanie hit her on her arm, "You gotta ask her truth or dare first"
Pouting, she asked her, getting a "dare" in response. Brooke knew she could NOT handle another shot.
"Well since I know you don't have a bra under that top, it's only fair that you take off your jeans. We can't be the only partly undressed girls here"
Brooke looked over at her brother, seeing if he would object but he was back to looking at Vanessa. Sighing, she took her jeans off, careful to not peel her light blue thong along with them. She sat back down, cross legged and trying to cover her panties with her top, grateful she decided to shave before going out tonight.
"Ronnie, truth or dare?" Melanie asked.
"Dare"
"Show us your cock"
All three of the girls giggled at Ronnie's reaction, but after some coaxing, he pulled down his pants and boxers, sporting a good sized erection that Brooke licked her lips at. He sat back down and asked the question to Brooke.
"Dare"
Brooke looked at Gabe in surprise after Ronnie dared her to blow him, but his seemingly interested reaction gave her the confidence to push Ronnie to lie down and began to lick him from the bottom of his shaft to the top. Looking over, Vanessa and Melanie decided to forgo the game and pounce on Gabe, stripping him of his pants and boxers as well as Vanessa's top. She caught a glimpse of his cock as they started pulling him upstairs, feeling herself get more wet as she was enthusiastically bobbing on Ronnie's cock. After a couple minutes of sucking and playing with his balls, she got up and squatted over him, slowly lowering herself on his cock. She took off her shirt and her nice C cups came into view, perky and with small nipples. Brooke leaned over, riding cowgirl and gave him a nice long kiss, her toungue exploring his. Her brown hair tickling his face as they continued making out. She could feel pleasure start to build up and starting riding faster, moaning so loudly that the three upstairs could probably hear.
Meanwhile, Gabe found himself in heaven with Vanessa on his cock and Melanie on his face. He had somehow managed to undo their bra clasps at the same time and was rewarded with both girls on their knees, Vanessa focused on his balls while Melanie sucked him off. Gabe felt Vanessa switch from ball to ball, giving each a long suck and tickling them with her tongue. Melanie managed to deepthroat him, the feeling of the back of her throat almost tipped him over the edge.
After the second time he told them to stop in fear of cumming, he was then pushed onto the bed where Melanie started off riding him and Vanessa sucking on Melanie's cute, perky tits, occasionally stopping to make out with her. Vanessa switched with her after a bit, even tighter than her friend, and began slamming down on him, getting him closer and closer to orgasm. Melanie took her place right over his head and began smothering him. With Melanie's pussy suffocating him, he couldn't let them know he was about to cum and started to unleash inside Vanessa. He grabbed her hips, slowing her down on his sensitive tip, enjoying the waves of pleasure washing over him. He could feel Melanie shaking as he brought her to orgasm and she collapsed on his left, one of his arms wrapped around her naked body and feeling her tits smushed against him. After resting a bit with Gabe still inside her, Vanessa got off and assumed the same position on the right, giving him a kiss on the cheek before snuggling against him. Gabe fell asleep with the largest smile plastered on his face.
Gabe and Brooke were on their way home when she decided to bring up what happened that night.
"Well that was something," she said laughing. "I hope you enjoyed Vanessa and Melanie"
Gabe just smiled and gave a chuckle.
"Truth or dare was kinda fun too"
"Oh yes"
"You just enjoyed seeing the girls in their bras"
"Well I didn't get to see all the girls, but definitely yes"
Brooke blushed at his comment.
"Anyways, dares are always fun like that. It always gives me a rush for some reason"
"Why don't we do it at home then?" Gabe offered.
"You think so? Ok," she replied. "How about we each get one a day, but they can only last for the rest of the day?"
He nodded, thoughts already racing through his mind.
"I go first then," he blurted out.
She gave him a pouty look. "Fine"
When they got home they both took a shower and regrouped at the table where Brooke started whipping up pancakes for them. Their parents were hardly at home, always taking care of their clients in overseas countries. The siblings were used to their absence and settled into a normal routine without them.
"Brooke, my first dare is that you go braless today"
Booke looked up at him and then looked down at her own outfit. She was wearing some short cotton shorts, a loose black tank top and a simple bra underneath. She smiled at him and reached back to unclasp her bra. As she took it off without taking her tank top off, Gabe's eyes were glued to her chest, hoping to catch a peek of nipple. She threw the bra at him and went back to whisking the batter. He could see her boobs jiggling in her tank top, no longer confined by her bra. When she pulled her hands back, he could see her nipples poke out. His cock was at full mast now.
Throughout breakfast, Gabe's eyes were glued to her chest. She reveled in the attention and felt some wetness building up in her panties. She decided there to spend the rest of the day in the common areas where Gabe could watch over her.
Other than Gabe following around Brooke the whole day, nothing further really happened. He caught quite an eyeful of cleavage whenever she bent over and plenty of sideboob. But when the two parted at night for bed, they both furiously masturbated, him with lotion and her with her vibrator.
In the morning she was waiting for him at the breakfast table with a smile on her face.
"Your turn. Drop those shorts and put these on"
She threw a pair of his compression shorts at him. He chuckled and smiled back.
"Fair play" he said, turning around and putting them on. He turned back and put his arms out. Brooke's eyes wandered down, stopping at the outline of his cock. The thin compression shorts did little to hide it, and she could tell by his erection that he was excited by her dare. He sat down at the table but she shook her head and told him to stand up.
"I gave you a show so I think I should be given the same"
She didn't know how, but his cock stayed hard the entire time. After breakfast, she watched him mow the backyard in just those shorts, his shirt off because of how hot it was. Though no longer rock hard, his cock made a sizeable outline in his shorts. She sat on the couch after, watching him walk around the house doing various chores, eyes glued to his shorts just like his were to her tits the day before. At night, they did the same routine as the last night, but her horniness made Brooke a little more vocal, which Gabe could hear if he tried hard enough.
The next morning, Gabe was waiting for her at the table. On it was a pink bikini. She held them up, seeing the bottoms were fairly cheeky and the top was slightly too small for her. They didn't have to say anything to each other, Brooke already knew what to do. She turned around and stripped, Gabe able to see a glimpse of her pussy as she bent over to get her legs in the bottom. She adjusted the top and turned around.
"Ta-da!"
She looked down at his crotch, a bulge slowly growing in his pajama pants. She giggled and went over to the fridge to start breakfast.
By midday Gabe was torn on what to do. His sister was watching TV with him while he watched her. His cock was straining against his pants, the urge to jack off growing by the minute, but he didn't want to miss out on his sister in her new bikini. She was laying belly down on the carpet in front of him, her legs spread and he could faintly see the outline of her pussy lips through the bikini. She looked back seeing the expression on his face and the bulge in his pants and spoke up.
"Will you let me have my dare today? I think you'll like it"
"He nodded, wondering what she had in mind. She knelt in front of him and said,
"Let me watch you jerk off. I've never really seen a dude jack off before"
