Mark stood next to the sink frantically trying to tease a load out of his throbbing cock. His phone showed an image of a busty redhead, teasing him with her curves, her large boobs falling out of the tiny top she was wearing.
Mark had always been an excellent Dad, but it seemed to him that over the year or so since his daughter, Jenny, had hit 18, every new outfit she bought was smaller, tighter and more revealing than the last. To make things worse, he couldn't help but notice that she filled them all so well.
He adored his daughter, she was sharp witted, funny and kind. But having a figure like a pumped-up version of his wife, Julia, and an unconsciously flirty nature made it increasingly difficult to regard her in an entirely virtuous manner.
He knew that unless he rid himself of his insistent hard-on, the planned family game night was going to have an increased level of challenge for him, a challenge for him to keep his eyes in the right place. This was something that Julia would most definitely notice.
His hand instinctively flew off his dick as there was a loud knock on the door. His wife shouted, "Hurry up Mark, we're almost set up downstairs." she laughed and then said more quietly, "You'd better not be jerking off in there, I've a feeling I might need you to be working on full throttle later on." Chuckling, she made a noise like a revving engine.
Mark had no idea how Julia did it. It was like she had X-ray vision or something, she always knew. Her teasing had killed it for him and he really didn't feel he could carry on now. Save it for later as instructed. His impressive cock had shrunk back to semi hard, but he still struggled to tuck it back into his pants and make it inconspicuous.
He took one last look at his phone before he swiped the glorious pneumatic redhead off the screen. He hoped Jenny would be wearing something more conservative this evening. But he knew that that was extremely unlikely these days.
When Mark entered the living room, his son Andy was already sat at the table. Andy smiled then silently pulled a face nodding towards the kitchen door. Mark paused, the sound of a heated discussion going on in the kitchen drifted into the room.
"...but now that your brother is an adult too, we're not going to get many more chances for evenings like this." He heard Julia saying in a firm, reasoned tone.
"Mommmm, I've already told the girls I'm going out with them, I'm sorry, but I completely forgot this silly game thing was tonight...." Jenny whined in response.
The two men looked at one another. Mark couldn't believe how grown up his son looked, as tall as him with the same, wavy brown hair, but with his mother's softer features and blue eyes. Andy was wearing the pair of sports shorts and T-shirt he got home in. No need to dress up for games night. He always enjoyed spending time with Mum, Dad and his (slightly) older sister, even if she could still be a bit bratty at times.
Julia walked in from the kitchen carrying a couple of bowls of nibbles and placed them on the table. Her long straight red hair was tied back and she had on a light button up blouse. Both men noticed how she was just revealing enough cleavage to advertise how good her boobs were.
Andy had come to terms with having a 'hot Mum' and tried not to think about it too much, despite the constant comments and teasing from his friends. If he was honest with himself, he'd have to admit that the fact his mates ogled her and his sister made him hard.
As Julia set the bowls down she sighed deeply, then, with a worn smile, said, "Jenny and I have come to an arrangement, she will be joining us for a few rounds of games, but has a very pressing engagement that she must attend later on, isn't that right..."
With a "Yes Mommm", Jenny swanned into the room carrying glasses and a bottle to set down. The guys stopped dead in place as they saw her walk in. Jenny was clearly not dressed for an evening at home, even by her standards.
She had the same long red hair as her mother, but wore it down over her shoulders. From the corners of their averted eyes, but of the guys observed the thin, vest-like top clinging to her large tits and the faint outline of her nipples on show. The top stopped barely below her jutting chest, leaving her midriff exposed. The gentle sway as she walked in made it obvious that she wasn't wearing a bra. Below this, she had on a tiny pair of white denim shorts and heels. Mark and Andy were both so practiced at 'not looking' these days, that they quickly turned the conversation to something more mundane to keep their focus.
"So, what shall we play first then?" chimed in Mark, breaking the tense silence between mother and daughter.
Straight away, Julia jumped in "Well, as its our first games night since Andy reached adulthood..." she was interrupted by a snort from Jenny who looked at her brother and pulled a face before smiling. They had always been close and this sort of teasing was just part of their antagonistic, but loving relationship.
Julia shot Jenny a fake "telling off" stare which made them both laugh and started again, "Well, as its our first games night since Andy reached adulthood, I thought we could try that game we got for Christmas."
"Oh, the one with the card and the drink?" asked Mark, getting up and crossing to the drawer where the game had been put, "Did you ever work out who sent it to us?"
"No," she replied, "its really odd, I asked everyone I could think of, but nothing, perhaps it was wrongly addressed?"
"Oh well, someone's loss!" Mark had returned to the table with the game box and sat down. "Becomes You -- a game for adults only." he read from the box. "Doesn't give much away does it, I presume its 'adults only' because there's alcohol in the drink?" He opened the box and removed the cards, bottle, four little shot glasses and instructions.
"Look at how cute the little glasses are!" Jenny commented in a mock girly voice, "It's not some sort of drinking game is it?"
"Not much of one with bottle this small," interjected Andy, picking up the bottle and examining it. "As long as I'm not going to have to endure some sort of dodgy sex game with you lot."
Julia blushed a little, "Well, it was addressed to all of us, so I don't think that it could be that sort of thing, whoever it was from. But if it makes anyone uncomfortable, we can just play something else. OK?"
