I had moved in with Maria just over a year ago. Her place made more sense than mine seeing as it was closer to work for both of us. There was a bit of an age gap, she was just 24 and I was 36 so we had some lifestyle adjustments to work through but we got it all figured out.
The problem(?) all started about a year ago. Her parents moved out of state and her younger sister Kendra, moved in with us to finish school before she was off to college. We had a love/hate relationship. I hated most of the shit she did, she loved torturing me. Once away from her parents she thought she had free run. We were responsible for her and laid down the rules, and law when needed, but she pushed the limits for sure. One thing she loved to do was try and get me in trouble with her sister. She would always wear skimpy clothing, or just panties and a loose shirt. She's walk out of the bath with just a towel and know I was in the other room. When I would call her out or complain to Maria, she would just say she was being a bitch and to ignore her, she would be gone soon. Being a male, I have to admit, seeing her like that was hard to ignore at times.
The day finally came when she left. Off, out of state to a big campus for 4 years. I didn't hate her, it's just would be easier without her around. Then came Christmas. We lucked out when Thanksgiving break came. Kendra went and stayed with her parents but I guess they clashed more so than when they all lived here. Maria offered to let her stay here for the holiday before I could even voice an opinion.
It started right where it left off. She had zero respect for us, or mainly me, and pranced around the house like she owned it, but had none of the bills to pay. Each passing day got me more and more worked up. The straw that broke the camels back is one day, Maria had left for lunch with her friends and I was home alone with the demon.
I walked into the kitchen from working on the car outside. Dishes piled up by the sink, pans on the stove, and there she was. Back to me, leaning on the island. Half cropped shirt, easy to tell no bra, and lacey, skimpy panties. Ass up in the air. I had it. Fuck this. She needs to know who runs this house and that she needs to stop this nonsense. If she wants to walk around all inviting like that, she'll get a visitor. I walked up behind her and grabbed her hips. One hand reaching down and unzipping my pants I pulled my cock out and began rubbing it on her ass. 'Is this what you want? Is it? You dress like a little slut all the time and someone is going to give you a cock in your ass"
I expected a scream, turn, slap and storming off. Instead she leaned back more and started grinding her ass on my cock. 'Mmmmmm there ya go Jimmy, does that feel better, does it make you harder?' Wait, was she playing this game now, throwing it back on me?' Ok, two can play this game. I reached forward and with one pull basically ripped her panties down and off her. They fell to the floor exposing her perfect ass. I admit, I was harder than ever now. And not sure what to do next. Would she back down?
Kendra reached behind and spread her cheeks open, 'Come on Jimmy, lets feel you fuck my ass' That was it. I spit onto her perfect hole and pushed my cock up onto her. Grabbing her hips and pulling her onto me. Crying out both in pain and pleasure as I entered her from behind. It was easy to see she had done anal before, and enjoyed it quite a bit. I started fucking her on the island. My cock pressing out from my unzipped pants and into her tight ass, slapping against her cheeks. I reached one hand under her shirt and felt those beautiful 18yr old tits. Smaller than Maria's but so firm. Almost hard. Her nipples were fully erect as I continues to use her ass as my fuck toy. I pushed her down onto the island, ramming harder and harder into her. Screams of pleasure exiting her lips as she began cumming. I never managed to make Maria cum from anal, but it wasn't something we often did. As she panted more and more I began to cum deep inside her. Filling her ass with my seed. The feeling of finally fucking this little tart after all she had put me though was just too much. I collapsed on top of her on the counter. My cock still buried deep in her. She was breathing hard under me. I could feel her still cumming as I stayed inside her.
From behind me I head her. Maria was standing in the doorway. I don't know for how long. I don't know what she had seen. Instant worry rushed over me. I was about to start and try to explain when she said 'It's about time you two got that out of your system. Can we now just get back to life?' I froze, actually still inside her younger sisters ass. Second guessing if I heard that right. As Maria walked past she looked at her little sister. Smiling she said 'See, I told you he was good. By the way, that was hot'
I pulled out of her ass and stepped back. Kendra turned around and smiled at me. She reached forward, taking my cock in her hand, never breaking her gaze at me. 'You're still a dick' she said as she dropped to her knees and took my semi limp cock into her mouth......
