My wife and I were in the process of moving to the same city as her whole extended family. I got a job offer and pretty much immediately moved and starting working. My wife ended up needing to stay back for longer. I moved in with some in-laws and there were a few siblings-in-law staying as well, including my sister-in-law, Sophie.
Sophie and I had always gotten along well. We shared a few TV shows that we liked and had a bit of a similar sense of humor. There were moments where I was sure that she had a bit of a crush on me. But she had always been a bit on the heavier side and I never saw her as an attractive person. Even so, I still enjoyed her company becasue she was fun to hang out with.
But when she moved to the same city around the time that I had we hadn’t seen eachother for a couple months. She had been going to the gym and running and it really showed. She lost weight, but kept her nice boobs and her butt was firm and tight.
One night my brother-in-law, Sophie, and I went out to a neighborhood bar for some drinks. Brother-in-law left early to play some video games with his college friends so Sophie and I stayed for a few more rounds. I’m not gonna lie, but I definitely felt some tension between us. I really tried to keep from sneaking peaks at her boobs, but she could tell when I would sneak some looks down her shirt.
On the way home I put my arm around her shoulder and she leaned in closer to me. We had to walk through a big park to get back to the house and there’s a little Japanese garden in the center of the park surround my some walls. Its a nice quiet spot and she suggested we walk through there to see some of the bonzai trees. I agreed, sensing some of her intention.
As we walked through we found out that a lot of the lamps weren’t lit along the path. At a particular spot Sophie kind of tripped and I grabbed her hand to help keep her falling. We didn’t let go of each other’s hands. We crossed a bridge over a koi pond and she stopped in the middle of the bridge. When I stopped too she stepped toward me and kissed me. She pulled away and apologized.
I grabbed her waist and pulled her back into a deep kiss. Our tongues intertwined and my hands began to wander. I grabbed one of her tits and began to massage it in my hand, she moaned into my mouth. One of her hands traced down my stomach and touched the front of the jeans.
I started to grind against her and moved a hand to start petting her over her dress. My cock was aching to be taken out of my pants and I didn’t think I could take it much longer. I unbuckled my pants and pulled them down, lettin her start to stroke my member. I lifted her dress a bit, slid her panties to the side, and started rubbing her pussy. She moaned softly at my touch. After a moment I tried to push my finger inside her and she eagerly pressed herself agasint it. I quickly began fingering her and her breath quickened.
“I want you,” I whispered in her ear, “Turn around.” She did as I asked, leaning forward against the bridge railing and I pushed her dress up and pulled down her panties. I placed my cock at the entrance to her wet pussy. “Tell me you want my cock,” I ordered.
“I want your cock inside me,” Sophie purred as she pushed her hips backward toward me. Her slit swallowed my whole length and she flexed her pussy to make it tighter for me. I started to fuck her slowly and tried not to cum too fast. I reached one hand around her waist and started to play with her clit and grabbed her hair in my other fist, pulling it and forcing her back to arch. She moaned in pleasure. As I began my rythm of thrusts into Sophie I kissed her neck and whispered, “You’re such a fucking slut, Sophie. Tell me how much you like my cock.”
She groaned in time with my thrusts, “Mm, I love your cock in my slut pussy. Hurry up and cum inside me.” I stopped playing with her clit and slapped her round ass and pulled harder on her hair. My thrusts got faster and I was getting closer to filling her with my cum. She reach her arm back and pulled my head closer to hers for a deep kiss.
My knees buckled as my orgasm took over my body. My cum shot into her pussy and my thrusts slowed. Finally as my dick softened I slipped out of my sister-in-law and stepped away. She shimmied out of her panties and used them to clean herself up and then tossed them into some nearby bushes.
We didn’t talk much for the rest of the walk home, but I think we both knew there would more for us to explore before the month was over.
