[MF] My Sister-in-Law Moves in

My sister-in-law, Sara, moved in with us. She was five years younger, starting college, and we lived much closer to her college than her parents who were in another state did.

We agreed to provide for her as long as she was sticking to her studies.

Off the bat she made her self comfortable. We were all always close, so it was no surprise. It was not long before she spent a good deal of her time at the house in as little clothing as possible. She had carried herself at her parents in much the same manner so it was no surprise.

It took a little longer for the flirting to start. Excessive touches when my wife was not around. Constant banter and remarks that were filled with innuendo. At first I ignored it but she took it as a challenge and upped the game. It turned into sleep wear that hid nothing if she moved a certain way. Casually sitting against me if I was on the couch reading after my wife went to sleep while she watched tv or played on her phone.

Asking about our sex life or talking about her own without prompting. Soon I caught on that she was purposefully flashing me while my wife was in the room and looking away. Sara would shift or bend over and look directly at me with a grin. When we talked she would call me Daddy just to tease me.

One night after I had made love to my wife and she fell sleep, I went to read and as I passed Sara’s room I heard her masturbating. Loud, her toy buzzing, as she moaned my name and several filthy comments that told me she was more than a little bit of a freak. And I could relate. She was getting in my head more and more.

In the end she made the first move. My wife worked during the day and I worked a rotating night shift so she had plenty of opportunity. I was in the woodshop working on something when she came in. She had on a leather skirt that was purely for show, a black and red corset top, gothed out red and black fuck me boots, and eye shadow to complete the look of going to a sex club or metal concert.
“Well you are dressed up today.” I said

“Yeah, I wanted to feel pretty and then my plans got cancelled.”

“Whatcha going to do now?” It was a strain to not eye fuck her as we spoke. She pulled the look off incredibly well.

“I figured I could spend some time with you. What do you like to do out here all alone?” She asked leadingly. We talked for a bit about what I was building.

“I’ve been thinking, Daddy.” She began.

“I’m not your Daddy, Sara.” I told her. I knew there was no conviction in my voice in this old argument between us.

“You took me in. You put a roof over my head, provide for me, check on me, help me. You’re sweet and caring. Fun, firm. And you have been fucking me with your eyes for weeks. I want to thank you, Daddy.” By now she was right in front of me. Between me and the workbench with her hands on me.

“Please? Let me just say thank you how I want. You deserve it, Daddy. I need it.” Her hands were sliding more and more intimately. She looked up and smirked at me as her hand found the erection tucked down my leg. She squeezed it.

“It’ll be our little secret. Don’t you want to reward your little girl for doing so well? Working so hard to make you proud?” I hadn’t moved. My mind was racing deeper into the gutter.

“Daddy?” She purred in my ear. I growled, unable to speak.

“I want you to fuck me, Daddy. Right here. Let me moan over that big cock Daddy. Whenever you want me.” She bit my neck. I snapped. My hands gripped her ass and the back of her neck as I lifted her off the floor. I kissed her and she melted against me. Wrapping her legs around me as I kissed her neck and bit until she whimpered.

“Fuck yes. Ohh, Daddy. Fuck me like your little whore.” She was grinding against me. My hands on her ass found no panties, but they did find a buttplug and her pussy already soaked.

I pinned her down on my workbench. I was all hunger and need. Spreading her thighs to lick and eat her until she was writhing, my face soaked as she squirted. I pulled her off the bench and had her on her knees.

“If this is my reward, stop being a greedy girl. Put that filthy little mouth to work.” I growled. My pants were kicked off as she hungrily took my in her hands. Her tongue swirled and stroked until I took her by her braid and pushed into her mouth and throat. She choked and gagged but took me. Enthusiastically sucking as spit ran down her chin and her makeup ran with tears.
I needed more. I pulled her away gasping and begging me to fuck her like a little slut. The bench was perfect. I jerked her to her feet and bent her over. Her firm ass was covered in handprints as I shoved inside her. Beyond thoughts of consequences I ravaged her. Choking. Biting. Throwing her around when she wasn’t riding me. It was loud. Rough. Messy. I didn’t pull out and she didn’t want me too.

After, we went inside. We showered together. It was done and this was life now. I have never been one to back down even from shitty choices. And I didn’t want to. Sexually we were as compatible as anyone I had ever been with. Similar tastes and fantasies Few hard limits.

The shower was useless. With a house to ourselves for hours we fucked again in the living room. Bruises and bite marks. Nails clawed down my back. And culminating in me fucking her tight ass until her legs buckled and she soaked the hardwood floor mewling breathlessly. I licked her clean and through another orgasm. One more shower as we talked and held each other.

Her clothing started covering more. Hiding the marks. But we had no regrets except that we had to hide it. We enjoyed it too much. And we were just getting started.
