The rematch came after lunch. Christina had come down dressed in a maid's outfit, carrying a tray of sandwiches and drinks. She unchained Susan and dropped off the tray before returning upstairs. She returned a half hour later with Jacoby. She no longer wore the maid outfit and was naked, just as Susan still was. She lay down on the concrete basement floor and spread her legs and arms wide apart. Jacoby approached Christina with another double-sided dildo. This object was at least three inches around and eight inches on each end. Jacoby slathered it with lubricant before shoving it deep into the girl's open pussy.
Jacoby motioned to Susan to come up and she obliged, lying down on the floor as instructed by the master. He positioned her over the other end of the dildo as he slowly slid her towards the other woman, pushing the dildo deep inside her. Susan spread her legs wide, sliding one under Christina's outstretched leg and the other over top as Jacoby told her. The man came around and grabbed Susan's ankle and pulled her closer to Christina until the dildo was completely buried inside both women.
Jacoby pulled out some rope and bound the girl's thighs together, preventing them from separating their legs from each other or pulling away from the dildo. Their wrists were tied with rope to hooks in the floor, keeping them spread.
Christina began rocking her hips as the dildo began vibrating inside the women. Susan could feel the woman's clit against her own and every movement the other woman made caused her to tingle. Soon she was rocking in unison with Christina, completely forgetting where she was or the man who was sitting in a chair watching the two women try to get each other off. Susan was determined she was not going to lose this battle and closed her eyes and focused only on the vibrations inside her and the pressure against her clit being applied by the other woman. The pair rocked and pressed against each other for what felt like forever to the two girls but it was really only a matter of minutes before Susan, driven to the edge earlier and left frustrated, moaned in delight as she felt the waves of pleasure roll over her body.
Christina was still rocking against her as their captor came over and began releasing Susan. The woman yelled in frustration as Susan was pulled away and the dildo was removed from her. She was still rocking in her bondage, trying to grind against nothing, not caring about the punishment she was about to endure, only wanting the sweet release she had been denied.
Jacoby handed Susan the flogger. "Twenty strokes, anywhere you like." Susan brought the whip down against Christina's bare stomach softly. "Susan, if you are not going to take this seriously, I will use that whip against you instead," Jacoby said. Susan pulled the whip back and brought it down sharply against Christina's stomach, eliciting a yelp of pain from the woman. Susan struck quickly three more times in the same spot, red stripes appearing on Christina's stomach.
Susan forgot herself, thinking now only of all the punishment she had endured, including being whipped by this woman earlier today and she brought the whip sharply down onto Christina's breast, striking her right in the nipple. Christina screamed "Bitch" loudly but Susan did not care, striking the woman 14 more times across her tits, red marks now criss-crossing her chest. Jacoby grabbed Susan's hand before she could administer any more blows than Christina deserved for losing. Susan collapsed to her knees next to the tied woman and began sobbing. Jacoby untied Christina and led her upstairs, leaving Susan alone in the dungeon with her tears.
