Bastienne was never one to shy away from playing games, especially with men. Her doctor, a stiff and serious older man, had been treating her for years, and she knew him well enough to understand his secret desires. Every time she went in for a check-up, he would insist on taking her temperature rectally - something that always made Bastienne squirm with embarrassment and excitement in equal measures.
Today was no different. As soon as she arrived at the clinic, the doctor ushered her into an examination room and began his routine. He asked her to take off her clothes from the waist down and climb onto the examination table, his eyes fixed on her round bottom. Bastienne couldn't help but feel a shiver of anticipation run down her spine as she positioned herself on the table, exposing her pink and puckered anus to him.
The doctor stood over her, his face flush with excitement, as he inserted the thermometer into her tight hole. Bastienne couldn't help but squirm and groan at the sensation, half-pretending to be in pain while secretly enjoying the intimate contact. As he took her temperature, she could feel the heat from his body pressing against her back, his breathing becoming increasingly erratic.
Finally, the doctor removed the thermometer, wiped it down, and presented it to Bastienne, his face beet red with excitement. "There you go, Bastienne," he said, his voice cracking slightly. "All done." Bastienne took the thermometer from him, concealing a smirk behind her hand.
"Oh, docteur," she purred, leaning back on the table and spreading her legs invitingly. "I think you forgot something." His eyes grew wide with confusion before dropping to her exposed pussy. Bastienne laughed softly, the sound like wind chimes tinkling in the breeze. "You always take my temperature rectally," she continued, her voice dripping with innocence. "But today, I think you should return the favor."
Without another word, she reached down between her legs, scooped up a sample of her fresh stool, and held it out to him on her palm. "Eat it," she commanded, her voice taking on a more authoritative tone. "Or I swear I'll tell everyone how inappropriate you've been with me all these years."
The doctor stared at the offering before him, his eyes darting back and forth between Bastienne and the offending sample. His face contorted in disgust, but there was something else there too - a desperation that made Bastienne's heart race. Slowly, he closed his eyes and opened his mouth, his tongue darting out tentatively to taste the sweet, musky tang of her shit.
With a soft moan, Bastienne watched as he closed his lips around the mound of feces on her palm, his tongue working it in and around his mouth. She couldn't believe it was happening - she was about to make her old, stiff doctor eat her shit! As he began to swallow, she squeezed another glob of hot, creamy diarrhea onto his tongue, his face scrunching up in surprise.
"One more taste," she purred, leaning forward and rubbing her soiled panties against his cheek. "Just to make sure you remember me." The doctor whimpered softly, his eyes still closed as he took one last delicate nibble of her filth before opening his mouth and swallowing hard.
Bastienne laughed softly, smiling down at him as he sat back on his heels, his face a mask of shame and arousal. "There now," she said sweetly. "That wasn't so hard, was it?" Without another word, she climbed down from the table, grabbed her clothes, and headed for the door, leaving the doctor to collect himself.
As she walked out of the room, she couldn't help but feel a rush of power and satisfaction. She knew he would never forget this moment, and she couldn't wait to see what other naughty games they could play together next time she saw him. After all, Bastienne loved nothing more than pushing boundaries and exploiting the weaknesses of others – especially when it came to their forbidden desires.
