It had been weeks since Sarah's soft pale neck had first felt the pressure of the collar and had her mind broken and lost completely to the pleasures of subservience. Her body now responded out of pure reflex to the touch and command of both her husband Chris, and her father-in-law Phil, and although the mindless surrender of the collar left no room for hesitation or shame, in quiet moments when not wearing it, Sarah couldn't help but blush at the realisation that she could now recognise and distinguish the cocks and cum of Chris and Phil but feel and taste alone.
Tonight however, the sensations of those weeks of exploration and pleasure were only memories that threatened to overheat Sarah's thighs if she dwelled on them too long, as she sat on the sofa beside her brother-in-law Jackson and his petite young girlfriend Cleo, sharing snacks and small talk with the younger Asian girl while Gwen was again busy in the kitchen, and Phil, Chris and Jackson intently watched the football on the TV mounted on the opposite wall.
Sarah knew enough about the Jaguar's from watching most weekly games with her in-laws, but as Phil turned his weathered older face toward her and gave her a smile and a wink, the memories and desires of his powerful bulk pounding her right here on this sofa made her flush, crossing her legs tightly to try to stop the spreading warmth from between her soft thighs as her hands smoothed her dress and she distracted herself with asking Cleo how College was going.
Gwen soon returned with a tray of nachos, and Phil finished his beer and offered to fill everyone's glasses while he was up getting another for himself, leaving Sarah and Cleo to giggle and cheer at the intense shared enthusiasm Chris and Jackson displayed as the brothers practically launched themselves to their feet to celebrate a Jaguar's touchdown, leaping over the girls to high five.
"Sarah, can you help me with the drinks for a second?" the booming voice of their father called out, and as the other four settled back in to watch the game, Sarah squeezed her hourglass figure apologetically past Cleo and Gwen and made her way through her in-laws spacious home to find Phil out in the garage, his thick quads emphasised by the squatting position he had assumed in order to look through the drinks fridge, in addition to his ever-present short gym shorts.
"You can close the door behind you" his voice rumbled more quietly, a familiar glint of playfulness in his older eyes.
Sarah's blue eyes widened, and for a moment she caught her breath, before her full lips returned a cheeky smile of their own at the lack of collar around her throat.
"And how would closing the door help us bring the drinks out to the family?" she asked in her best innocent voice, heart pounding in her chest as her father-in-law turned and stood. Despite lacking the height of his eldest son, her husband, Phil still made her feel small looking down at her, his boozy breath close enough to taste as he leered back at her.
"Because you're going to take your panties off first, and I know you appreciate the privacy" he chuckled deep in his broad chest, "Or at least, when you're uncollared you do."
Back in the living room, the game had reached the half time break, the Jaguar's ahead by enough for the mood in the house to be positive, but not so much that Chris and Jackson were willing to talk about much else. Cleo brushed her long black hair back behind an ear and smiled politely at Gwen, thanking her for the hospitality, but the older blonde woman's attention was elsewhere.
After a few minutes, Chris finally noticed the look in his mother's eye, and when his younger brother excused himself to go to the bathroom, the taller man crossed the room to kneel beside Gwen's chair.
"Everything ok Mom?" he asked, his bearded face showing genuine concern as she smiled a thin-lipped smile back at him, her slender hands clasping his in reassurance.
"Oh yes, you enjoy the football sweetheart, I'm just wishing your father would hurry back without getting too... distracted... back there." She smiled, glancing nervously towards the Asian teen on the sofa not wanting the sordid secrets of her husband and daughter-in-law to become more widely known.
Nodding after a moment's thought, Chris stood up, still holding his mother's hand, and flashed a warm smile across the room at Cleo.
"Are you alright here until Jackson gets back?" he asked, "I need to help Mom with something before the second half."
As soon as the polite assurances had been made by the younger girl, Chris was leading Gwen upstairs and sitting her down on the edge of the guest bed in one of the spare bedrooms.
"What's wrong Mom? You're not getting jealous of Dad and Sarah, are you?" he asked, concern in his blue eyes as he knelt in front of her.
Gwen's narrow face broke into a wry smile, and she let out a short laugh before shaking her head, her fine blonde hair much more like that of her eldest son than any other resemblance in the family, and the squeeze of her hand expressing her adoration for the caring young man he had become.
"No no, you know your father and I haven't had a sex life for years, and that's by my actions not his. I've got nothing to be jealous about, trust me!" she smiled, "I'm worried about you more than anyone, are you sure you shouldn't be jealous of that gorgeous wife of yours sneaking off with your father, when we have other company and you aren't there to give your blessing or join in?"
Chris heard the hint of hardness in his mother's tone and smiled, he had been chatting and planning with his Dad for so long about turning the lovely but strictly monogamous Sarah into an open-minded cum slut for them to both use and share, that the thought of his wife willingly doing anything with her father-in-law without a collar or command only stirred his cock to semi-hardness. But his mother's concern warmed his heart at the same time, and so he moved to sit beside her on the bed, easily wrapping her shoulders under a long arm, even as his eyes wandered once more to the ever-generous bosom barely hidden by her dress.
"You don't want me to be jealous, is that what you're worried about Mom?"
Gwen's nod was a gentle confirmation of that concern, and yet Chris' erection continued to grow, imagining he could hear Sarah begging for Phil to fill her with cum downstairs as he let his free hand rest on his mother's soft thigh.
