My Fiancé's Sister ~ Trixya

Chapter 12 - Doing What's "Right"

"Oh my god..." Trixie moans ad Katya enters three fingers inside of her. The two of them sprawled out in her and Alex's bed. The bed sheets rub sensually against Trixie's back as her body is thrusted upwards towards the headboard with each upward stroke, and she moans again, louder.

"Told you." Katya replies smugly. She is straddling Trixie's thigh with one hand planted on the bed next to Trixie's chest, the muscles in her arm tense from holding herself up. She curls her fingers up to hit Trixie's g-spot.

Over the last week, since they went dress shopping, the two of them have been coming back to Trixie's apartment daily to have sex during Katya's lunch break. At first Trixie protested, Alex didn't deserve to be betrayed like this and she didn't think she could handle the guilt that would wash over her as Katya pulled her into the bedroom. But as soon Katya's body was on top of hers, she all but forgot who Alex even was.

Just as Trixie is about to hit her climax, she hears the front door being unlocked and opened. Katya stops her movements and whips her head towards the door, listening intently.

"This can't end well." She mutters, pulling her fingers out.

Panicking, Trixie shoves Katya off of her and scrambles out of the bed, trying to find her clothes and throwing Katya's at her in the process.

"Fucking hide or something! Get in the closet!" Trixie hisses sharply, hopping around and struggling to get her shorts on. Her mind is racing. How could she have been so stupid and careless? Why was Alex even home, and did he hear anything? Would he leave her and kick her out?

"Been there, done that." Katya retorts, buckling her belt. Trixie can't help but laugh and kiss her sloppily before quickly shoving her into the closet, pressing a finger to Katya's lips, shushing her.

Trixie fixes her hair and clothes, trying to get her breathing back to normal. She opens the door a crack, slipping out and quietly shutting it. Alex walks up to her, pulling her into a hug. He lets go and she moves to block the door handle.

"Hey, what're you doing home?" Trixie asks nervously.

"I wanted to bring you lunch," he says "but it appears as if someone's already done that." He looks deep into Trixie's eyes, dripping with guilt and fear. He couldn't hear voices, but he could hear the stumbling around of more than one person behind the door when he came home. "So, what's his name?" He asks casually.

"What? What are you talking about?" Trixie tries to act innocent.

"Drop it, Trixie. I know you've got someone in there." He sighs, pushing her out of the way.

"There's no one in there Alex." She says, blowing it off and trying to appear shocked that Alex would even think she would bring another person into their house, their bed. "Let's go eat." She

tugs on his arm towards the kitchen. Alex shakes her off, opening the door and stepping in, looking around.

Trixie's knees are weak and she's getting lightheaded. There was no way this was happening. She knew this is ten times worse than him catching her in bed with five guys.

He crosses his arms, checking for anyone under the bed, behind the dressers, and in the bathroom. Unless the person climbed out the window and scaled the wall, running off, Alex knows the only other place to look is the closet. He swings the door open and comes face to face with a flushed Katya.

"You've got to be fucking kidding me." He mutters, grabbing Katya's arm and pulling her out. He turns to Trixie, still gripping Katya's arm tightly. "My sister? Of all the people you could have cheated on me with you chose Katya? And in our bed? Why?"
