The time I got into trouble helping my sister move [FM]

My parents had me and my sister a full decade apart. Because of that, she and I never really clicked. For most of my childhood, she viewed me as the kid who was getting in the way and treated me as such. By the time I reached my teenage years, she had moved out, and as a result, the relationship between us never got fully repaired. We’re civil towards each other now, there’s no screaming, but it’s clear that she and I are never going to spend time together without our parents as the hinge.

When I was nineteen (I’m in my mid-thirties now.), I had to help my sister and her boyfriend move house. My Dad was driving the truck for them, my sister and Mom went along with him. There were family members meeting them at the new house, to begin unloading the truck. I volunteered to stay back with her boyfriend to finish loading some items which hadn’t fit into the truck, into his car. My sister actually protested me being left alone with her boyfriend, she said it wouldn’t make any sense because I “wasn’t being useful anyway”. She was entirely right, actually. I had spent the entire day up until that point doing everything I could to avoid actually working. I was the first one to take a break, or disappear for a few minutes, and I had worn a floral patterned sundress with a low neckline, and wedge heels, neither of which were conducive to manual labour.

My sister’s boyfriend at the time was a guy named Javen. She had met him in college because they studied similar things. I’d had a crush on him since the first time she brought him home for thanksgiving. I had never done anything about it though, aside from a little bit of flirting here and there. He was black, and about six feet tall, with an athletic build. Javen kept his hair in short curls atop his head, and he had well kept stubble that fell shy of a beard. He was shirtless in basketball shorts due to how hot it had been that day, and I had made no effort to hide the fact that I had enjoyed looking at him throughout the day.

He and I made short work of loading the rest of their stuff into his car, both because there wasn’t actually that much to load, and because I actually helped once my sister was gone. I apologized to him for being a complete pain the whole day. He actually laughed, and told me it was no problem. He had siblings too, so he understood the strained relationship. Javen was one of the only people who had ever called me out on exactly what I was doing up until that point. I think deep down I knew I was being a bitch because I hated my sister, but it wasn’t something I had fully admitted to myself yet.

We chatted for a while about siblings, and what a pain it is growing up with older ones. He had an older brother, though not an age gap as big as mine, so we shared a lot of the same complaints. We were sitting on the hardwood floor of his empty house talking, I was milking the break from my family and my sister for as long as it was worth. My sister ended up calling to see how we were doing, but it had only been thirty minutes, so it was clear that she had called to check up on us.

Because of the emptiness of the house, or maybe just because of the volume he had set on his phone, I heard both sides of their conversation. She was complaining about me! The fact that I’d done nothing to help all day, the fact that I had dressed ‘like a little slag’, it went on for a little while. Javen turned like he was going to get up and leave the room once she started, but I put my hand on his arm to get him to stay and let me hear it. He looked confused, but didn’t stop my sister from her rant. My sister proceeded to compare wearing a sundress in August to streetwalking, both an insane comparison, and infuriating. I decided if that was how she viewed me, she might as well be right.

When Javen got off the phone with her, he apologized for the things she had said. I shrugged it off, and told him that I was used to her not liking me. I hadn’t known though, that she thought I was a slut. He corrected me, pointing out that she’d never said anything like that about me in the past. He said she was probably just venting because moving is stressful on everybody. That stress is something I had no frame of reference for at the time, but I know all to well now.

I told Javen that if she thought I was being a slag, I might as well live up to it a little bit. He laughed, thinking I was joking, and suggested I sunbathe nude on their back deck, or maybe to make a pass at one of the neighbours. I laughed, and pushed things a little bit further, asking Javen why he wasn’t making a pass at his girlfriend’s slutty sister. He told me that he absolutely would have, except for the fact that he had no game. My sister had been the one to ask him out, apparently.We sat in silence for a few moments after that, probably a couple of minutes, actually. The joking energy had drained from the room and there was suddenly palpable sexual tension between us.

The combination of angry and horny is a dangerous one for me, I’ve never had much impulse control as it is. Looking back I sort of wish I could say that I fought the temptation, but I didn’t. Instead, I laid back on the hardwood floor, and propped myself up on my elbows with an arched back, smirking at him. I told him that if he wanted her sister, all he had to do was ask nicely. Javen was getting the message by that point, and moved himself next to me on the floor, reaching down to run his hand up the bare skin of my leg.

I pulled my dress up for him, and he moved my white panties to the side before pushing a finger inside of me. I shuddered and moaned when he did that, leaning to the side to rest my head on his shoulder. I kissed his neck as he fingered me with a steady pace, then nipped at his ear before I asked him to add a second finger.

Javen obliged, and pushed a second finger inside of me with a twisting motion, increasing his speed as well. I pushed my hand into his basketball shorts too and started massaging his cock through his boxers. He was semi-erect already, and quickly hardened under my touch. I pushed his shorts and boxers down, stroking his cock with my hand once it was freed. He let out a moan that sounded loud in the empty house, and asked if I was sure. I told him yes, but that we didn’t have much time.

That was all the confirmation Javen needed, he pushed me down on the floor completely, turning me on my side before giving my ass a smack. I rolled further, and raised my ass in the air for him. My arousal ran down my thighs as I raised myself, I’ve always been juicy, but the fact that I was about to fuck my sister’s boyfriend had me worked up far beyond usual. I told Javen that I was on birth control, and he chuckled saying that was good, because he didn’t have a condom.

Javen hurriedly pushed his pants down, and slid his cock inside of me with little hesitation. I pushed back into him and moaned, then he spanked my ass and began fucking me at a steady pace from behind. The entire house was pretty much empty, so it was loud. The sound of Javen’s hips slapping against my ass as he fucked me filled the air around us and mixed with my moans as they reverberated off the bare walls.

Any nerves he might have had were evidently gone. Javen pulled my arms behind my back and fucked me harder, using my wrists to pull me back into him with every thrust. I moaned louder, and asked him if my sister let him fuck her that roughly. He didn’t respond orally, but let out a grunt and pressed my cheek into the floor, really pounding me. He was actually quite a bit rougher with me than I had expected him to be, I adored it. Eventually he could hold back no longer, and pulled out quickly, blowing his load over my ass.

We had to leave fairly quickly after that, so I cleaned up as best I could using my panties as a towel because we had none. Then I tossed them in a trash bag, and we went to meet everyone else. I struggled mightily the rest of the day to keep from flashing people, and Javen grinned at me whenever we made eye contact.

Nothing ever happened with him and I afterward. He and my sister did end up getting married, and later divorced for reasons unrelated to infidelity.
