The next day

*With Blake off to work and Rily at college, the house fell quiet, save for the occasional rustle of papers from Mike's makeshift workspace. Suddenly, the front door creaked open, signaling Alena's arrival. Mike looked up to see his mother-in-law saunter in, clad only in a skimpy bra and panties that did little to conceal her mature curves.*

*Mike's jaw dropped, taken aback by Alena's brazen display of sexuality. Memories of their previous encounter still lingered, and he felt a wave of discomfort wash over him.* "Alena, we need to talk about what happened last time," *he began, his voice trembling slightly.* "It was a mistake, and it won't happen again."

*But Alena merely laughed, a cold, mocking sound that sent chills down Mike's spine.*

*Without warning, Alena spat directly onto Mike's face, the saliva dripping down his cheek in a humiliating display of contempt. Seizing the opportunity, she snatched a pill bottle from her purse and popped one capsules into her mouth, washing them down with a swig of water.*

*Mike's eyes widened in shock as he recognized the pills - the same suspicious BLK brand Tyrone had gifted them the day before. A dark realization dawned on him: perhaps these **** were the catalyst for Alena's sudden increase in sexual aggression.*

*Before Mike could express his concerns, Alena hiked up her panties and flipped onto her stomach, presenting her bare rear end to him.* "Clean my ass, Mike," *she demanded, her voice dripping with condescension.* "Since you're so pathetic, you might as well serve a purpose."

*Mike stared at Alena's exposed buttocks, his mind reeling from the rapid succession of shocking events. The cool, clinical detachment with which she issued her command only added to his sense of disorientation and powerlessness.*

*Despite his reservations, Mike found himself drawn towards Alena's inviting flesh, his own desires momentarily eclipsing his apprehensions. With a heavy sigh, he leaned forward and pressed his lips to her puckered anus, the taste and texture foreign yet strangely arousing.*

*As he worked to clean her thoroughly, Mike couldn't help but wonder if the BLK pills were indeed responsible for Alena's newfound boldness. And if so, what other transformations might they bring about in those around him - including himself? The thought sent a shiver down his spine even as his tongue continued its ministrations.*

*Alena's abrupt departure left Mike shaken, his mind whirling with unanswered questions and unspoken fears. The lingering taste of her anus still fresh on his lips, he struggled to process the bizarre encounter, torn between revulsion and an unsettling arousal.*

*His primary concern, however, was the potential danger posed by the mysterious BLK pills. Knowing he couldn't broach the subject with Blake directly, given the connection to her mother, Mike felt compelled to act discreetly. The sealed box, now stashed away, served as a tangible reminder of the threat lurking in the shadows.*

*Determined to intervene before things escalated further, Mike resolved to find a subtle yet effective way to dissuade Alena from taking the pills.*
