Cassie's Curse

Technicalities
Mamie stood rooted to the spot, staring in horror at the scene in front of her, like watching a slow-motion train wreck unfolding, the cars piling up like the years of her life, all being destroyed in a single, gut-wrenching act. She wanted to turn and run; but for some reason, she had to keep looking. Her sister, on her knees, there in front of the couch; Mamie's husband sitting in front of her; his pants around his ankles; his bare knees spread wide; his head thrown back in ecstasy, resting on the back cushions; his face screwed up in passion while Cassie's head bobbed frantically on Reggie's vein-bulging erection.
And Mamie thought: I've never done that to him. In all our years together, I've never knelt in front of him like that. Is that why this is happening? Am I to blame?
Reggie moaned loudly without raising his head, while simultaneously, Cassie made a surprised "Mmmph!" sound, her cheeks suddenly bulging. And then, in a mixture of awe and revulsion, Mamie stood and watched her sister's throat muscles contract, relax, contract again as she gulped. Slowly, purposefully, the kneeling woman turned her head to the left and stared across the room, up into Mamie's eyes. Cassie worked her throat one last time, one last swallowed betrayal, like taking a final sip of a friendship, then she slowly slid her lips from Reggie's deflating shaft. And she smiled.
Mamie made a noise, deep in her clutched throat, though she later couldn't remember exactly what kind of noise it was, and she spun to her left and fled toward the stairs leading up to her bedroom. She was sitting on the edge of the bed, her eyes dry, her knees together, her back straight, prim and proper and ladylike, when Cassie pushed the bedroom door open and joined her, sitting beside her as they always sat, like they always had, as if nothing at all had happened between them.
"Go away," Mamie said softly.
"No, I won't" Cassie replied calmly.
"I hate you."
"No, you don't."
"I thought you loved me."
Cassie, already making contact all along their sides, shifted slightly and tucked her arm through her sibling's, grasping Mamie's hand. "I do. Nothing's changed."
Mamie tried to pull away, then gave up. Gave up, just like always. "How can you say that, after ...." She didn't find it possible to put the act into words.
"I never wanted you to see that. I was ... compelled to do it. I was going to explain it to you later. I was expecting your little errand to take longer."
"I knew right away something was wrong at the pharmacy when they didn't have any prescription for you. And my cell phone was dead, and I couldn't call you. And, what do you mean 'explain it to me?' How could you possibly explain something like that? And what do you mean 'compelled?' How long have you and Reggie ...? When did you start ...? I thought you were a lesbian, for Chrissake!"
"We didn't, and we've never, and I am, and I'll explain it all to you; but it's a long, sad story." She took a deep, sighing breath. "I'm in real trouble, big sister." Cassie always called her that, because Mamie was nine months her senior. Mamie was also four inches shorter, and that added irony to the moniker.
The comment made Mamie start, and she turned and stared deeply up into the other woman's eyes. Her emotions were like a cyclone, going in every direction at once.
They had always been so close, so ... together: the perfect odd couple. Mamie was petite though curvaceous, shy, introverted, bookish. She had been hopelessly in awe of the boys in high school, constantly in the grip of hormonal lust, yet emotionally incapable of finding any sort of romantic attachment. Cassie had always been tall, svelte, athletic, socially outgoing and sure of herself.
Their only commonality had been their devotion to each other; and that was the rock on which their separate lives had been built. Mamie was certain that they had never lied to one another, never questioned, always confided. Long before Cassie "came out," she had divulged her sexual identity to her sister, and they plotted together how to break the news to their parents and friends. And it was Cassie who had played matchmaker between Mamie and Reggie during senior year, then had visited them regularly all through college. Only two years ago, she had been Mamie's maid of honor and helped her plan every detail of the wedding.
She had been crushed when Cassie had gotten the sports scholarship to UIC, then decided to stay in Chicago after graduation. Mamie and Reggie moved back home to the St. Louis area after four years at the University of Missouri. The distance between the two cities wasn't THAT far, but sometimes it seemed unbearable. Mamie had missed her sister SO much, and had been hugely excited this morning when she heard that Cassie would be coming into town and staying with them for a while.
"You're in trouble?" Mamie asked meekly while wondering silently why she wasn't staying on-topic. She'd just caught her sister giving her husband a blowjob, for cryin' out loud! But somehow, this new revelation seemed even more shocking. "You're having trouble, and you haven't told ME about it?"
