Hello there. I’m Mark, here to share a fairly recent and ongoing thing between my sister, Lauren and myself. I am 45 and Lauren 42.

We are 2 of 5 siblings and have always been the “wild ones” as we only graduated high school and not college like our siblings. This is one reason why we bonded so much and have always been close. Neither one of us is married and we started to text and talk nightly over last summer. Lauren really wanted to go see this metal band at a small theater not far from us and we made a date to go. I knew we’d be drinking and having a good time and invited her to spend the night. She thought this was a great idea and accepted.

She came over the Saturday afternoon of the show and we hung out and had a couple of drinks and then got ready. When she came out of the bedroom I was stunned. First of all, she’s very good looking, long black, wavy hair, green eyes, huge tits, I am talking D cup for sure but how she was dressed got me. Her tits were exposed almost to her nipples and she had on a short skirt with open toe platform heels. Her nails painted a dark purple on her fingers and toes. I was a bit taken aback and she asked me how she looked. I said one thing that set the tone of the evening : “If you weren’t my sister”. This made her laugh and feel good. I wore all black with a black leather jacket and off we went.

We had a great time and actually held hands occasionally and she grinded back into me a few times causing a very hard cock. Needless to say, it felt like a date.

Once we were home I fixed another drink and put some music on. She was acting really care free and silly and I knew she pretty much had a little too much to drink as did I. It was nearing 1 am and Lauren said she was going to get ready for bed. Except she went in my room and not the guest bedroom. After about ten to 15 minutes she called out to me and when I went in she was lying stark naked on my bed with her feet touching and her knees far apart exposing her pussy completely. Her tits looks huge and after seeing the deer in headlights look on my face she followed up on my earlier comment by saying “Tonight, I’m not your sister”. I’m like “Hold that thought”. I went in the other room, removed every bit of my clothes and went back in with a full 7” hard on. I wear my hair in a pony tail, am 5’10”, black hair and 170. When she saw my cock she said “Get up here” and that was that.

I laid down on top of her and we locked lips in a deep, tongue swirling kiss. We kissed passionately for several minutes before I moved down to her huge tits. I squeezed and sucked on them for all I was worth and then she bounced up and rolls me over and straddled me so were were in a 69. The first taste of her pussy drove me insane, she was shaved around her lips and had a square patch of black hair on the mound. I drove my tongue deep in her pussy and her mouth felt like a dream on my cock. She pumped the shaft in her hand while sucking it and the only reason I held on was the alcohol. She squeezed my balls as she took my cock very deep in her mouth. I decided to go further and spread her ass cheeks apart and flicked my tongue across her asshole. This seemed to turn her on more so I continued licking it and put a finger in it. I worked my finger in and out when she suddenly flips around and mounts my cock and said “Fuck me good, Mark”. She began to ride me, her tits swaying in my face so once again I sucked, licked and squeezed them. Her pussy was wet and tight and every inch of my cock was in her going in and out, in and out, in and out. We fucked like this for a good ten minutes, she had cum twice already and I knew I was getting there. I lifted her off of me onto her back and drove my cock deep in her pussy. She wrapped her legs tight around me and I pounded her pussy with all I had. A few short minutes later I felt the eruption on the way and shouted out and began shooting ropes and ropes of cum deep inside her drenched pussy. I rolled off of her and she immediately went back to sucking my cock until damn if she didn’t get me hard again

Once I got just as hard as before, she takes my hand and leads me into the living room. She put her knees on the couch, holding the back of it and crouched down so her asshole was open and exposed to me. I couldn’t believe it, she wanted me to fuck her ass. I got a little saliva and rubbed it around and inside her asshole and then pushed my cock in a very little at a time. In about 90 seconds I was all the way in. She was making all kinds of grunts and groans as I held her hips and slammed my cock repeatedly into her asshole. She bucked back and met me thrust for thrust. I began pounding her ass harder and faster and in seconds I erupted with spurt after spurt of cum into her ass. More than before if that was possible. I was spent and so was she. We slept together naked that night and fucked half the day on Sunday when we were sober so it wasn’t just the alcohol. It’s unusual I know but she stays here all the time and we are seeing each other exclusively. Totally out of the blue and unexpected.
