My sister came over this afternoon to have sex before she went into work and we had some of the roughest sex we’ve had in awhile. I live alone at my apartment so we usually hook up here for the most part. She came over and had her work clothes in her bag and she was wearing leggings and a t shirt. We hugged and kissed and she said she would meet me in bed so I got undressed and just laid in my bed naked stroking my cock waiting for her to come out of the bathroom. She came out completely naked and climbed up between my legs and started stroking my cock for me before starting to blow me. I turned her around and brought her ass up to my face and started eating her out while we 69 for bit, I started fingering her pussy and she crawled off and got in doggystyle position and told me to fuck her hard. I rubbed my dick against her pussy from behind until she couldn’t take it anymore and I just slid my cock inside of her, she was so wet I could feel her pussy swell with moisture when I went inside and just started a ducking her hard from behind, she gripped the sheets and buried her face in the bed and yelled harder and I just started pounding her as hard as I could until she fell flat on her stomach, I put her on her side and raised her knee up and really started getting deep inside her. My cock is pretty big and sex in this position use to be a bit of a struggle with it being uncomfortable for her but now I have her trained to take my dick in any position. I’m not sure how long we fucked but at one point I was fucking her so hard her face was red and she started tapping out just as I came inside her. I pushed as deep as I could for my last pump and emptied my load inside her. We laid in bed together breathing heavy before getting in the shower for a quick clean and rinse. She cleaned me up in the shower and sucked my dick a bit before getting out and dressed to head to work, she left me a joint on my kitchen table and brought me Panda Express. I smoked the joint and ate on my balcony thinking about the next time she might be able to come over so we can fuck in some new position. We explore all of our fetishes together, she wanted to try pissing on me so I let her piss on my legs in the shower, she wanted us to both try ass eating so we’ve done that, we’ve tried anal, and much More. If you have something we should try let me know, I’m always open to suggestion especially in the bedroom, I want to experiment on some new stuff with my sister soon.
