My promiscuous brother in-law

The next months were absolute bliss, Riley made sure he got his daily dose of my ass and I was loving every moment of it, although my wife was starting to get cranky since Riley made no intention of leaving the house and I honestly I didn't want Riley to leave.

As Riley's bitch there was some rules I had to follow.

Rule.1- I had to be clean and shaved all over, Riley liked his ass neat and hairless and everyday I took special care of my ass and cock, there wasn't a single hair on it alongside the rest of my body.

Rule.2- I always have to refer to myself as Riley's fuck bitch and also ask him for permission if I wanted to suck his cock or have sex with him.

Rule.3- no matter how horny I was I should never stroke my cock or play with my ass, my orgasms belongs to him and only him could make me cum.

And lastly Rule.4- I should be prepared to get fuck anytime or anywhere, willingly give my body to him for his use and disposal and no other man could fuck what's his.

I obeyed every single rule and failure to do so ended with my ass whipped and sore.

I still had issues with my wife since I got all the satisfaction I needed from riley, I didn't have the energy to make love to her and so each night she'll pretty herself up and eventually get me to have sex with her but they was still a small issue of me not being able to cum and this was problem number 2.

It was a Saturday night, I was asleep right besides my wife after having sex, I couldn't sleep that night my cock was still hard as a rock and I needed Riley to quench this ache.

He's been busy for the past few days and he hasn't had time to fuck me, although he did instruct me to send pictures of my ass to me and would leave very dirty voice notes which always made my cock hard but i had to obey to Riley's 3rd rule and my cock would ached for hours leaving me disoriented.

I was finally drifting off to sleep but then I felt a large frame lie besides me and I got a big whiff of his scent, riley was here and my cock twitch for joy his hands were on my waist pulling my body towards his chest and I could feel his hard cock between my ass.

"Hey slut, miss me" he whispered and pushed his hard cock into my ass and I grind my ass back at me, I missed him so much and my hole tingled in anticipation for his cock.

I nodded and turned my head to me seeing the smirk in his face as he pressed his lips against mine, he tasted like beer his hairy face tickled my skin as we kissed hungrily, tongue plunged into my mouth exploring and searching for mine, then our tongues were wrapped around each other exchanging saliva as he continued to grind his cock into me.

His hands moved up to my tits and squeezing them, fingers brushing against my nipples as his lips descended down my neck suckling and bite on the skin and I couldn't help but moan. My wife stared and riley stopped his movements till we heard the soft snores of my spouse.

He continued to squeeze my tits and I bite down on my lip to stop myself from moaning, although I was quite scared my wife will wake up and catch but I couldn't think well with his cock throbbing between my butt crack and I immediately wanted that.

"Riley" I whispered and pushed my ass back towards his cock rubbing my plum cheeks on it.

'What is it slut" his lips were back on mine again his left hand on my crotch as he squeezed my hard cock causing my precum to drip.

"Please fuck your bitch hole riley" I begged wanting nothing more than to be pounded hard and have my ass sore even though my wife was right there.

"Hmm always eager for my cock huh you dirty little slut" he squeezed my dick again and I threw my head back, biting down on my lip so I wouldn't wake up my wife and having to get fucked right besides her made this so much better.

He pushed down my boxers till my bottom was completely bare, he spat on his cock and stroked it a couple of times holding the base as he slowly slid into my ass. As part of his 4th rule of always being prepared it meant I always had to have lube in my ass for easy penetration.

His cock slid easily into my hole till I was completely filled he raised my leg up slightly and slowly slid in and out of me so as not to make the bed squeak.

"Hmm that's it benji, squeeze that ass around my cock" I clenched my ass around his cock as he continued to fuck me slowly I stroke my dick alongside and moaned softly, my gaze went to my wife as she continued to sleep not knowing her slut of a husband was getting his ass fucked by her brother.

Riley pulled out his cock and shoved it back in, I could hear the sounds of his length digging into my hole, i stroked my cock faster closing my eyes.

"You're so fucking tight bitch" he whispered to me, sucking my ear lobe into his mouth as his hips rotated and thrust further. 

"Just look at you, getting your slut ass fucked right besides your wife" his dirty words were turning me on and I stroked and squeezed my cock faster.

"And you'll do this again, bitch, you'll let me fuck you again, and again and again" my toes were curled up in pleasure and everything he said was absolutely true.

"Remember when I fucked you in the garage when you begged for my cock in your dirty little hole before you left for work, or the time you sucked my cock in the kitchen while my sister was in the living room" I remembered vividly, I remember how I clenched my ass at the office so his cum wouldn't leak out and how I lick and swallowed every shot of load in the kitchen.

"You're such a cock loving slut, and am going to give it you bitch, going to fuck this little hole till you cant fucking walk" I moaned and stroked my myself faster I was getting close very close.

"You wanna cum slut, do it, cum! Show me how much you love being a cock slut" his thrust were harder and I grunted and cummed hard the first rope landing on my wife arm and the rest on the sheets.

I held my breath and stared hoping she wouldn't wake up and then I felt riley pull out and step away from the bed.

"Come on" he beckoned on me to come and I slowly got off the bed and followed him as we tip toed out of the room and into the hallway locking the door gently behind us.

My back hit the wall and he turned me around, his arm around my neck as he plunged his cock back into me, fucking his cock hard and fast, grunting as he warm breath hit my neck.

His body pushing me into the wall, he was holding back in the bedroom so as not to wake up my wife but out here in the hallway he was a monster his cock pushing into me in long hard thrust.

Using my hole as he's play thing as I clenched my ass around his cock, he granted and held me tighter sending one last thrust into my ass as he cum shot into my hole filling me up and at that time I realized I had cummed along side with him, my load dripping down my thigh.

He left his cock in me for a few minutes and pulled out and I clenched my ass to hold them in.

"5am, bright and early I want to wake up with my cock in your mouth, got it bitch" 

I nodded "yes riley" I felt his lips on my neck and his hands squeeze my ass.

"Good, now get yourself back in there before my sister wakes up" he left me there and went into his room, his boxer In his hand and his cock dangling I got back into my room and anticipated for 5am, eager to suck his cock.
