Ben and Susan’s unusual relation – part 1

This is a story about ben and susan who are siblings but….let’s begin

“Hey Ben, have you seen the car keys?”

I didn’t even look up from my computer as my sister walked in the room.

“Yes, but you’re not getting them,” I said.

“Come on, I just need it for like half an hour,” she said. “Mom and dad won’t know.”

“You got that dent in the door last time you took it out, I think they’d notice something like that.”

Susan pouted as she sat down heavily on my bed, purposefully coming into my line of sight.

“That was an accident, it’s not like it would happen again,” she said.

“It doesn’t matter, you’re going to follow the rules this weekend whether you want to or not.”

I had to play the older brother a lot with Susan. I wasn’t actually older, or not by a significant amount anyway since we were twins and we didn’t actually know who was born first, but I had definitely developed into the more responsible one. My sister was way more impulsive and generally uncontrollable; two months since we turned eighteen and she’d already been grounded for getting caught drinking. It was a good thing I could get her to listen to me sometimes or who knows what kind of trouble she’d get into. To be fair she could mostly take care of herself and when she did something stupid she usually learned from it.

This Friday was the start of another weekend where I would have to try keeping her on leash, so to speak. Our parents would be gone until Sunday and I really didn’t want them to think we couldn’t be left on our own for a couple days.

“It’s always rules with you,” Susan said. “You never want to have any fun.”

“But when I do want to do something I have access to the car,” I countered.

Susan could see that she wasn’t getting anywhere with me and abruptly changed tactics.

“You still like Sherin right?” she asked, referring to one of her friends who I did indeed have an interest in.

“I never admitted to anything,” I said warily.

“Whatever. I’m just saying that I wanted to go pick her up so she could come over for a while. You’d like having her around wouldn’t you?”

I stayed silent since I actually did kind of like it when Sherin hung around. I could have sworn she was at least a little interested in me too, although that might have been wishful thinking.

“You could always try asking her out while she’s here,” Susan added.

“Okay, now I know you’re making things up ’cause you’re constantly telling me not to hit on your friends. And you know I wouldn’t even do that anyway.”

“Well it’d be kind of weird if you hooked up with someone I know.” She shrugged. “I just think it might be worth the trade off in this case. She’d probably say yes if you asked.”

That made me hesitate. I didn’t think Susan was lying which meant that I might actually have a chance with Sherin. I wasn’t desperate, not exactly, but I wasn’t rolling in dates either.

“You mean that?” I asked.

“Of course I do. She probably would have said something to you already if she thought I’d be okay with it.”

Susan knew she had me now, I could tell by that look of triumph that she could never quite manage to hide from me. Partly just because I’d seen it so often.

“Fine,” I said, giving in to inevitability. “But I’m driving and you’re not arguing that one.”

My sister leaped off my bed and wrapped her arms around me.

“See, you’re the best brother ever. Can we go right now?”

“Give me a couple minutes.”

Susan practically bounced out of the room as I leaned back and sighed. Now I’d have to be even more on my toes to make sure nothing went wrong or I’d be getting rightfully blamed as an active participant. Still, there was a chance that it could turn out to be worth the trouble.


We picked up Sherin without incident and when we got back the two girls spent some time doing whatever it is they do. In some ways it might have been better this way since as long as Susan wasn’t bored she was less likely to come up with bad ideas just to amuse herself.

It didn’t take me long however to realize that despite what Susan had convinced me, I still couldn’t simply walk up to Sherin and ask her out. I didn’t have the kind of confidence that would let me initiate something like that, particularly with my sister hanging around. Fortunately it turned out I didn’t have to.

I was lying on my bed that evening reading something for my English class, which would get a derisive comment from Susan if she caught me, when Sherin walked up to the doorway.

“Hey, mind if I come in?” she asked.

“Uh, no, that’s fine. I mean, yeah, sure.”

Great, I was having trouble with monosyllabic words. That didn’t bode well. I sat up and tossed the book onto my desk as Sherin came closer.

“So I guess I should thank you for letting me come over tonight,” she said, looking casually around my room.

“Oh that’s okay, it’s not a big deal,” I said, trying to downplay my involvement instinctively.

“Your sister said you might have something to ask me,” Sherin continued.

Shit shit shit, what did Susan tell her? I glanced toward the hallway to make sure it was still empty. The two of them probably wouldn’t be working together just to tease me, but I couldn’t discount the idea entirely.

Sherin gave a small smile at my look of panic. “That’s okay, I know she’s playing games,” she said. “But I think you do kind of like me don’t you?”

“Yeah, I do,” I admitted, not meeting her eyes.

“Good, ’cause I kind of like you too. And even if Kris is just hoping you’ll wuss out of saying anything, she did still give me permission.”

“Permission for what?” I asked automatically.

I didn’t bother pretending to take offense at the ‘wuss out’ comment because it was pretty dead on for me. As my sister would well know.

“For whatever. I figure we could probably do something just to bug her if you wanted.”

“Like what?”

“Like I could give you a blowjob.”

I heard the words and they matched up with her lip movements, but it seemed like I must have misunderstood somehow. Sherin had always been friendly around me and everything, but her suggestion went against most of what I understood about girls. Outside of when she came over with Susan, or occasionally when we bumped into each other in school, we’d never really spent any time together. The idea of someone just casually offering me anything sexual without at least going out a couple times was completely foreign to me.

“Um, okay,” I said faintly.

Confused or not, enough of my brain was functioning to accept. Unless this turned out to be a prank after all, and I really didn’t think it was since it definitely wasn’t my sister’s style, there was no good reason to refuse.

Sherin knelt down in front of me, but didn’t immediately make any further move.

“You don’t have to be so nervous,” she said.

“I know, it’s just I haven’t really done anything like this with that many girls.” Plus I was generally more comfortable with them when I did, but I could think of a good way to say that.

“That’s okay, I haven’t done this with that many guys either.”

As though my concern had anything to do with our relative amounts of experience.

“Or is it because I’m moving too fast?” she asked, tilting her head slightly. “I swear I don’t usually, I’m not a slut or anything. But I know you well enough that I can trust you not to be a dick about it later like some guys.”

“And you can always have Susan kick my ass if you’re wrong.”

“That too. But I don’t think I am.”

I watched in fascination as she reached for the front of my pants and undid them with only a slight fumble. My cock wasn’t completely soft, but it was far from hard which I found a little embarrassing as Sherin carefully fished it out. She didn’t seem to think there was anything wrong and acted as though it was nothing out of the ordinary. When I thought about it, I really was more used to a little foreplay before any clothing started coming off, so to speak. It was perfectly reasonable that I wouldn’t be as worked up as normal.

“It’s been a little while,” Sherin said. “I might be out of practice.”

She certainly didn’t seem out of practice to me. Her fingers seemed to know exactly what they were doing as they gently stroked me to full erection. Then again, maybe I just wasn’t much of a connoisseur. Any girl getting me off was better than doing it myself as far as I was concerned.

“That feels good,” I assured her.

The corner of her mouth twitched upward as she looked at me for a second, then leaned closer to my lap.

“This’ll feel even better,” she said.

I drew in a sharp breath as her tongue flicked out and ran across the head of my cock before disappearing again. She repeated the movement a couple times before licking a path along the entire underside of the shaft. I had been getting very close to full hardness and Sherin’s playful tongue was enough to get me the rest of the way.

With her hand wrapped around the base of my cock she parted her lips around the tip and started to take me into her mouth. She used a kind of bobbing motion as she worked me deeper inside until she was about halfway down my full length.

“I keep forgetting how much I like doing this,” Sherin told me as she pulled back briefly. “I kinda wish I could take it a little deeper though, I have a wicked gag-reflex and it doesn’t really work out very well if I go too far.”

“You’re doing pretty well as far as I’m concerned.”

“See, that’s what I’m saying about being able to trust you. I said almost the exact same thing to this one guy, and he wanted to, like, ‘help me get used to it’ or something. I’d have needed to like him a lot more before I’d let him shove his dick down my throat.”

It wouldn’t even have occurred to me to expect anything more than what Sherin wanted to do. Partly just because that’s the sort of person I was, and partly because what she was doing felt so good anyway.

As her focus returned to my cock I once again got to feel her take as much of me as she could into her mouth while her fingers circled around the part she couldn’t reach. She looked incredibly sexy as she sucked me off despite still being fully clothed. I loved the way she would look up at me every now and then without breaking her rhythm.

I was so wrapped up in the experience that it was another few minutes before I noticed Susan watching from the doorway. It belatedly occurred to me that Sherin had never actually closed the door and my sister would naturally have been curious what her friend was doing in my room for so long.

My initial reaction was simply to freeze up, unnoticed by Sherin since I had been keeping fairly still anyway. I didn’t think Susan could see that much from where she was, but she could definitely guess what was going on. Once she saw that I had noticed her she bit her lip for a second before turning around and walking away.

“Shit,” I said softly.

Sherin must have decided that I meant I was close to orgasm because she started working even harder on me. Despite my concern over what Susan was thinking I actually was getting close and soon my need to cum overrode everything else.

“I’m gonna cum,” I said, just to give Sherin some proper warning.
