Still covered in her goodbye sperm from Omega Nu, Caitlin waited tied up in the backseat of Grace's truck as Grace took her back to her house. It had been roughly three months since her first night at Omega Nu and she was happy to be out of there. All the clothing she currently had on was the choker they had given her.
However, Grace still instilled a terrible fear inside her. Caitlin felt sick thinking about what Grace would do to her. She had not had a chance to punish her for any of her behavior since the night Caitlin had fucked her for the first and only time.
Grace kept looking at the backseat, her eyes filled with lust. Caitlin felt like she was being fed on a silver platter to a hungry wolf.
"Did they hurt you permanently at all? Are you hungry?" Grace asked. Grace did not sound like she cared about Caitlin; she sounded like a farmer asking about a cow before buying it.
"They definitely hurt me, but it shouldn't be anything I won't recover from," Caitlin responded. She was even more worried by Grace asking about her than if she had just ignored Caitlin in the backseat. "As for food, I haven't eaten today, so I am pretty hungry." For some reason, she thought being honest was a good idea for these questions. She could not imagine Grace doing anything bad to her for being hungry. Even if it was just because Grace wanted her fuckmeat in prime condition, she did have to care about Caitlin's wellbeing.
The drive seemed to go on for an eternity but eventually they made it to Grace's house. Caitlin was still naked and helpless as Grace got out and opened the door to the backseat. Grace picked Caitlin up, slung her over her shoulder in broad daylight, spanked her ass and brought the naked, sperm-covered blonde into the house. Two of Grace's neighbors gave them a strange look. Caitlin watched the outside world leave her as Grace walked through the door, before shutting it. Caitlin felt cornered.
Grace undid the hogtie trapping Caitlin and let her walk.
"There's a plate of lasagna on the table. Help yourself to it," Grace told her. Caitlin was worried. It reminded her of the day she became Grace's sex slave. Grace had drugged her using a bottle of water. However, her stomach's grumbling seemed more important. If Grace wanted to rape Caitlin, she was going to, whether she was drugged or not.
Caitlin sat down and wolfed down the lasagna. Grace sat across from her. She had put a towel on Caitlin's chair to avoid getting any cum on her furniture.
"From what I heard, and the little I saw, those Omega Nu boys were pretty rough with you. Not just them either, but Brenna too. You must be so glad to be back in the arms of only one person," Grace said, a sinister smile clear on her face.
Caitlin did not want to answer. She could never admit to being happier in Grace's hands, especially to Grace, even if the alternative was Omega Nu. She quickly finished her food and placed her dishes in the sink.
Grace wrapped her arms around Caitlin from behind. Caitlin felt a strapon already poking against her butt through Grace's skirt. She couldn't tell exactly how large it was but it felt huge. Caitlin felt her stomach sink. Grace really did have big plans for her tonight, in every sense of the word.
"I'll take care of these dishes. You go clean up. Wash that cum off yourself. The bedroom upstairs has a bathroom with a shower. You smell exactly like I would expect a frat house sex slave to smell. Take a nice, long shower and I will be ready for you when you get out," Grace whispered into her ear. She finished off with a kiss on the cheek before letting go of Caitlin.
"Now go!" she said excitedly, giving Caitlin a quick spank.
Caitlin was still reeling from being back here in Grace's house, but she really wanted a shower. The food had been fine, so it would probably be okay for her to take a shower. Grace's giddy mood was still throwing her off. She thought she'd be tied up, handcuffed, pinned to the ground or bent over as soon as Grace got her in the house but she wasn't. At least, not yet.
That shower was the single best hour of Caitlin's life in the past three months. All the sperm still on her flowed down the drain. She felt like she was getting rid of her whole time at Omega Nu in that shower. It was her first shower in weeks where she did not have anything shoved into her.
She washed her hair and every part of her body as thoroughly as she could. When she was done, it was the cleanest she had ever felt in her life. She looked at herself in the bathroom mirror and thought, "It's a shame that this is being wasted on Grace." Her heart felt heavy in her chest as she exited the bathroom.
What she saw was a truly unexpected horror. Grace was laying sideways on the bed, fully nude with her head propped up on her arm, looking Caitlin up and down, grinning from ear to ear. This was a pretty normal sight, with the exception of one part.
Caitlin realized she had never felt a strap on earlier today. Grace had a monstrous penis where her vagina used to be. It was already bigger than most of the ones Caitlin had dealt with at Omega Nu, and it was still flaccid.
