Mark pushed open the heavy glass doors of the gym, a determined expression on his furry face. He had let himself go over the past few years, and it was time for a change. As he scanned the room, his eyes landed on a figure that made his heart race – Rita, a sleek and muscular Labrador, and the daughter of a special forces unit commander.
Rita caught his gaze and flashed him a dazzling smile. "Well, well, well, if it isn't the man of the hour," she said, sauntering over to him. "I haven't seen you in here for a while. I was starting to think you'd given up."
Mark chuckled, feeling a blush creep up his cheeks. "No chance of that," he said. "I'm determined to get back in shape."
Rita's eyes raked over his body, taking in his full build. "I can see that," she said, her voice low and sultry. "You've got the potential to be a real powerhouse. With a little hard work and dedication, I have no doubt you'll get there."
Mark felt a thrill run through him at her words. He had always been attracted to Rita's confidence and charisma, but he had never acted on it. He was married, after all, and loyalty was important to him. But as he looked into Rita's warm brown eyes, he couldn't help but feel a pull towards her.
Over the next few months, Mark's body transformed. His muscles grew pumped and defined, and his stamina increased tenfold. Rita and Mark's friendship deepened, and they found themselves spending more and more time together. It wasn't long before they began a six-month affair, sneaking around behind Mark's wife's back.
One evening, they decided to take their relationship to the next level. Rita's parents were out of town, and they had the apartment to themselves. As they made their way to Rita's bedroom, Mark's heart pounded in his chest. He had never been with a woman like Rita before – confident, strong, and in control.
In Rita's bedroom, they made love under a red thin silk blanket, on a red silk bed. Mark, however, couldn't shake off the guilt of cheating on his wife, Lena. His phone rang, interrupting their moment. It was Lena, asking where he was. Mark, irritated, told her he was with a friend and that he'd be back the day after tomorrow.
Rita, who had been eavesdropping, asked Mark when he'd tell Lena about them and leave her. Mark replied that he'd kick her and their son, Lucky, out of the house when the divorce papers were ready.
Rita, unaffected by Mark's short temper, proposed that they start a family of their own. Mark, surprised, agreed. Rita took control, straddling Mark and riding him. Mark, who hadn't felt a vagina without a condom for a long time, came abundantly.
As they lay in each other's arms, Rita thought that Mark would make a perfect husband and father. Mark, still feeling guilty, couldn't help but wonder if he was making the right decision. But as Rita's warm body pressed against his, he couldn't deny the attraction he felt towards her. It was a new regime, indeed.
