My sister my house guest 2

Me and my sister start getting closer we start sharing one bed.

The next we kind of went back to normal. We went shopping and restocked the cupboards.
Later Sarah went out and brought two guys back with her. They had been drinking and didn't notice me standing in the dark hallway watching them fuck my sister.
Honestly what did they expect me to stay in my room and listen to them go at it. They were making a lot of noise.
I know my sister had her tongue pierced and I know what that means. Sarah enjoys sucking cock. I even felt it rub my shaft when she sucked me off.
But to watch her kneel down and suck two cocks while in her bedroom. Watching suck one and then the other cock back and forth.
Then they got her on her bed and took turns fucking her. The first guy fucked her until he shot his load, and the other guy fucked her sloppy cunt.
They had a break, and I got out of there in case they went for a piss. When the noise started up again, I returned. Sarah was back on her knees sucking those cocks again. I wondered if she was tasting her own pussy from those cocks after they had just been in her. Next thing she is ordering them around one on his back on her bed while she is lubing up the other guy's cock.
I watched her get sandwiched on her bed.
After they had finished both guys left and I went into her room with a damp towel to help her clean up. She jumped up and kissed me on the lips She could see
I was already hard; Sarah dropped to her knees and sucked me off.
I looked down her she smiled and threw me a kiss before deep throating my cock. Feeling suck, me off while in a 69 is one thing. But standing and watching her do it is even better.
I closed my eyes and shot my load. When I opened them again, I could see in Sarah's mouth my cum all over her tongue she moved it around before swallowing it.
She handed me her dildo and asked me to fuck her with it.
At first, I took it slowly poking it into slowly. But it was her toy that she had used a fair bit. So, it went in with ease and so I was fucking her with it as hard as my arm could swing back and forth. I discovered her orgasm face as she lay, and I fucked her with a dildo.
She stopped me lubed my cock and asked me to fuck her arse again. She got her legs off the bed and lay on her belly I got off the bed and took her doggy style. I hung onto her hips as I fucked until I cum in her bottom.
I slept in her bed with her again just holding while we slept.
I next morning I woke up with Sarah sucking my cock again. We had a relaxing Sunday at home got a few things done around the house and started acting more like a couple than brother and sister.
What she was wearing around the house in front of me. A white tank top without a bra. Her nipples were poking through that top, and you could see the dark areolas through the cloth. A mini skirt with no panties under it. Every time I looked at her, she would flash her gash at me.
Just before she went to bed, I begged her to let me do the one thing I had wanting to do. Go down on her. While she did not have a pussy full of cum. Afterwards she kissed me on the lips and sucked me off. then she went to bed.
Monday, Tuesday and Wednesday we did the same thing each day. Sarah got up and went to work. Later I got and went to work. I got home and she was in bed. After I eaten and showered, I got in bed with her. The only thing between her legs was her dildo.
Sarah started teasing me, of a morning while I lay in bed and she got up she took the dildo still covered in her juices and deep throated it.
I wanted to lick or suck her juices off of the dildo. But at the same time, I didn't want to lick or suck a cock shaped object.
Then the dreams started I started dreaming of Sarah having sex with other women this led to a threesome and Sarah pegging me. Then I was having nightmares where she was sharing me with the guys she was bringing home.
