“Alright girls, show me what you’ve got.” 18-year old Gina said. She laid her cards down on the table, to reveal a pair of fours.
“If you insist.” Across the table from Gina, Tabitha revealed her cards: a pair of threes and a pair of sixes. She grinned as the other girls groaned in disappointment.
“Dammit, Tabby,” Elizabeth said, throwing her cards down. “How are you so lucky?” Opposite her, Kaitlin did the same. “I thought you were bluffing Kat.” She said with a rueful grin. The redheaded girl shrugged.
“I guess tonight’s my lucky night, Lizzy.” Tabby said, smiling. “Now, let’s see them underoos.” The three girls glumly stood up. Gina had on a white t-shirt and light blue shorts, while Kaitlin was wearing a dark green blouse and a brown skirt. Lizzy had on her jeans but had already lost her shirt, literally. Beneath it, the teenage girl had on a white bra.
While Tabby watched, shuffling the deck, the three girls stripped. Gina and Kaitlin pulled off their shirts. Underneath, Gina had on a grey sports bra, while Kaitlin had a lacy black one on. Lizzy unzipped her jeans and slid them down her long legs, to reveal a matching pair of white panties.
“Cut.” Tabby said, handing the deck to Kaitlin. The girl did and passed it back. Tabby took it and quickly began dealing out the next hand.
It was Saturday evening. Gina’s parents were out for the evening, and they’d given their daughter permission to invite her three friends over to keep her company. There was nothing good on TV, so the four had got out a deck of cards. After a few rounds of Go Fish, Elizabeth had suggested poker instead. When the others pointed out they had nothing to bed, she’d just grinned. “How about this then? The losers have to take off one item of clothing.” Elizabeth said.  
“And,” Tabitha added. “When you’ve run out of clothes, you get tied up for the rest of the evening!” The other three had nodded, each eagerly imagining what they would do to the other three once they had won.
After a quick discussion over whether socks or shoes counted as one item of clothing or two or whether or not jewelry counted, the game had begun. The first few hands passed quickly and soon all four had lost their socks and shoes. Now the real fun began…
Gina glanced at her cards. Not much. She had three spades. She tossed the other two cards in and hoped for a flush. She frowned, as Tabby quickly dealt her two more. No such luck. Lizzy won that hand, with a pair of kings. The only other girl who had anything was Kaitlin with two fives.
“Looks like my lucks starting to change.” Lizzy said as the other girls stood. Gina pulled down her shorts. Beneath them she had on a pair of grey panties. Underneath her skirt, Kaitlin had on a pair of lacy panties that matched her bra. To the girl’s surprise, Tabby stood and slid off her jeans, leaving her shirt on. “I decided not to wear a bra tonight.” She told them with a mischievous grin. “Guess I picked a bad night, eh?”
Lizzy dealt out the next hand. Gina grinned as she saw a pair of aces in her hand. To her relief, no one else had better. Lizzy and Kaitlin both slid off their bras, while Tabby unbuttoned her shirt and slid it off, leaving all three of them in just their panties.
Tabby grinned, sitting up, bare chest thrust forward. “Come on, you two, be proud of what you’ve got.” Beside her, Lizzy and Kaitlin giggled, blushing slightly.
“It’s your deal, Gina.” Tabby said, passing the deck to her. Gina grabbed the cards and shuffled them. She dealt out hands to each of the girls, then looked at her own cards. She smiled. Not bad, a pair of fours. She threw the other three cards in the middle and grinned when she got another four back in return.
“Three fours.” She said, laying her cards on the table. Lizzy and Kaitlin groaned, resigning themselves to an evening in bondage. Tabby grinned. “Straight.” She said, flashing her hand. “Your bra, Gina, and then let’s deal with these two losers.”
“Fine.” Gina stood, reaching behind her back to unhook her bra. Meanwhile, Lizzy and Kaitlin hesitated, faced red. “Do we have to?” Lizzy asked.
“Come on,” Tabby said, hands on her hips. “We all agreed to this. No backing out, just because the cards didn’t go your way.” She grinned, “I guess we could tie you up first, and then you couldn’t stop us from taking your panties off…”
“Fine.” Blushing red, the two pulled their underwear down and kicked them into the pile of clothes. Gina and Tabby grinned, while their naked friends turned crimson with embarrassment and tried to cover themselves with their hands.
Before they’d started the game, the four had gathered a supply of rope, tape and scarves to deal with the losers. Grabbing a handful of scarves from a nearby chair, Tabby handed a couple to Gina. “Ok girls, turn around and put your hands behind your backs…” The two soon-to-be helpless captives glumly complied. Gina and Tabby advanced on their prisoners and gleefully proceeded to tie them up.
“Hey, not so tight!” Lizzy complained, as Gina quickly lashed her to her chair with rope, coil after coil circling her torso, pressing it against the back of the chair. “Not so-mmmppphhh!” her cries were cut off as Gina pulled a scarf between her teeth, gagging her. Nearby, Kaitlin meekly accepted her own gag.
“Not bad…” Tabby said, as she and Gina stepped back to admire their work. Their two friends were quite securely trussed to their chairs, bound with rope and scarves. The two captive girls squirmed, getting a feel for their bonds. They moaned as they realized they weren’t going anywhere soon…
“What do you say we call it a tie and have some fun with these two…” she said, grinning. The two captives grunted angrily, shaking their heads.
“I think they want some company this evening.” Gina said, stepping back to the table. “Besides, you aren’t getting off so easily…” She handed the deck to Tabitha. “You deal.”
“Alright then. One last hand to decide everything…” Tabby said, shuffling the deck. She dealt five cards to the both of them. Nearby, Lizzy and Kaitlin watched intently, wondering which of their friends would join them in bondage, and which one would be their tormentor for the evening.
“Two pair.” Gina said with a smile, setting the cards down on the table. Her smile disappeared as Tabby just grinned.
“Full house.” The other girl said. “And I think that makes you my prisoner for the evening…”
“yep.” Gina said, shaking her head in resignation as she stood up. She felt her cheeks flush red as she pulled down her panties and threw them in the pile of clothes. She dragged her chair over to sit beside Kaitlin and Lizzy.
“Arms behind the back of the chair, please.” Tabby said, grabbing some rope and stepping behind Gina. Gina did as she was told and felt her friend grab her hands and quickly tie them together with a scarf. “hmm…you said your parents would be home at 11, right Gina?” she said, grabbing another scarf.
“That’s righ-mmmppphhh…” Gina was cut off as Tabitha pulled the gag between her lips.
“Well then,” Tabby said, glancing at the clock. “We’ve got lots of time to play…” The three captive friends moaned into their gags…
