Jessica had watched her sister-in-law abuse her brother for years - verbally, emotionally, and even at times sexually. In a way, despite being John's sister, Jessica couldn't blame Ellery. John was weak-willed, and unwilling to defend himself. Not only that, but Ellery was an absolute powerhouse of sexual might - her breasts were huge, her body well-proportioned, and her ass with just the right amount of jiggle. That being said, and despite the understanding, Jessica couldn't just stand by, and watch as her brother was subjugated and oppressed, even by a woman so worthy of undertaking such actions. And so she planned, and waited, until Christmas, and the boys of the family left for their yearly football game - a moment when all that would be left in the house was the women.
On that early morning, when all the men had left, and all the women still slept, Jessica crawled into Ellery's bed, pulled off the covers, and positioned herself behind the woman she intended to tame. Slowly, she lowered her hand down the body of her familial rival, and with the most subtle of motions, brought it under and into Ellery's panties, and to bear against her sister-in-law's waiting clit and pussy. Jessica's hope was that her brother's wife would slowly rouse, and be so shocked by the sudden engagement, that she would simply lie there and allow herself to be dominated - fighting back only when it was already too late.
Despite that plan, and even the possible soundness of it, Ellery was only pretending to react in the way her rival expected. For in fact, she was ready. She had sensed it. The growing boldness in Jessica. Catching the glares at the dinner table, and the wincing whenever precious brother was insulted. And so she too formulated a plan. One that involved her waiting for Jessica to attack, allowing her to do her worst, and then once her best had been exhausted, to counter attack. And so like a fly into a spiderweb, the loyal sister fingered Ellery slowly, gently, not wanting to arouse the dominating spirit of her enemy. That paucity of passion gave the busty blonde exactly what she wanted, a meek, drawn out attack, which would allow for her to play the role of expectant submissive, just long enough for Jessica to gain enough confidence to stay engaged when the moment of rebellion occurred.
Ellery could feel a powerful orgasm building within her, and so she went to turn, both the tables and her body, so she could take control of her husband's sister, but as she made that attempt she found herself stuck. With thighs wrapped around her abdomen, and a firm hand squeezing at one of her massive tits. She had made a classic mistake, assuming sexual strength equated to physical strength, and that her own carnal prowess meant that she could overpower her opponent when ever she pleased. Such was not the case, as Jessica was stronger, faster, and had been trained in both wrestling and jujitsu, and so she held firm, as her fingers worked, draining Ellery's strength, concentration, and bringing her closer and closer to an quickly approaching orgasm. The realization that she had so mistook her position, and the mishandled the fight for sexual domination caused her to cry out:
