Strap-on Brother

"Jules, hi! Waiting for a shower?"

I looked around to see my sister-in-law. I knew she came to this gym, but I'd never actually seen her there before. It was a Saturday morning, not my usual time for working out. "Oh, hi. I was, but there seems to be a long queue, and I don't like the communal ones. I think I'll just go home and shower there."

She nodded agreement. "Yeah, dunno why, just doesn't seem right."

I hesitated. "Want to come back to mine? Shower there and then grab a bite? Mark's away so we could have a nice girly lunch."

"Sure. Nat's tided up doing something all day. That would be nice." Nat is her husband and my little brother.

We drove our own cars back to my place, and went in. "Shower in the bathroom's playing up at the moment, " I said. "The one in the en suite is better anyway. If you use that first and I'll just get a few bits out of the freezer for lunch while you're there. Clean towels under the wash basin." She made polite attempts to suggest I should go first but I brushed them off.

Two women at home by themselves? Talk of a shower? I know what you're thinking and you're wrong. I found some bits for lunch, put a bottle of wine and some beers to chill quickly and did a rapid tidy up of the living room.

Turns out I was tidying the wrong room.

Annie appeared wearing a towel, smiling happily. Smirking almost. Odd.

"Finished! Love your shower." It was nice - we'd just had it done.

I went into the bedroom to take my turn, undressed, and nearly died of embarrassment. Hanging on the radiator - put there by myself that very morning - was what Annie had presumably been smirking about. It was my favourite strap-on harness and a very large black dildo; I'd washed it in the bathroom after giving Mark a good seeing to, and then left it there safely to dry. Stupid, stupid, stupid.

Ah well. Annie was cool. Just suppose it had been my Mum ...

I showered, pondering whether to mention it or just pretend it hadn't happened. I was still unsure when I came out. It was a lovely sunny day, so I just slipped on a skirt and tee shirt, hair not done properly and no make up. I like not having men around sometimes.

Annie had dressed but was still smirking, which made my mind up.

"Sorry, didn't remember I'd left that out. Oops."

"That's OK. You guys had some fun last night then?"

"And this morning."

"Good God, really? So who's the big strap-on fan then - you or Mark?"

Are we really going to have this conversation? Looks like it.

"I suggested it. He was reluctant, but once he'd tried it he couldn't get enough."

"And were you as keen?"

"I adore fucking him. He's got a sexy arse as well."

"It looked pretty big?"

"Yeah, that one is. We started small, but just got carried away. I take it from your reaction that you've never tried it?"

"I've suggested it."

"And Nat said not?"

"Exactly"

"He doesn't know what he's missing."

I poured some wine and we moved outside to sit in the sun.

"Actually, Nat and I are having some difficulties, sex-wise."

"Really?" Nat is as attractive as Annie - which is very attractive. He'd had had a string of sexy girlfriends before settling down. I just somehow assumed that they would be doing fine.

"We have different views."

"Ah. Yes, Mark and I had a phase like that"

"You did. What happened?"

"Hey, I didn't mean to talk about me. You go on."

"No, I want to know. You've obviously solved it. What did you do?"

"Just between us? No pillow talk to Nat about his sister's slutty behaviour?"

"Is there slutty behaviour involved? Anyway, yes, no pillow talk."

"Well it seemed that whatever I wanted he didn't; whatever he wanted, I didn't. So we did a deal: we'd both try absolutely anything that the other really wanted. After trying it properly if we still didn't like it we'd move on. I mean we didn't try everything. It had to be something that we genuinely believed that the other would enjoy if they would only have a go. And one of mine was to fuck him with a strap-on."

"What else?"

"What did we try or what did we settle on?"

"Both?"

"You keep secrets?"

"Yes!"

"Threesomes, bondage, exhibitionism, anal and watersports. Oh and some home-made vids."

"And what was good?"

"Well, I hate watersports. Well, I hate being pissed on, at least. And I don't hate anal, but his cock is just too big for me there. And bondage it turned out that neither of us actually liked it when we had a go."

"So you're left with porn, threesomes, strapons and exhibitionism"

"No comment"

"Is that why you've got no knickers on?"

Oh God. "Sorry. If I tell him later that I've spent the day without them on he'll get such a boner. I'll go and put some on. Sorry."

She stopped me. "No, don't be silly. Fine with me."

"So what does Nat want that you're not up for?"

Now she went coy. "Well, it all seems a bit tame after what you said." Thank God I'd left out the cross-dressing.

"I bet he's got a list of kinks he'd like to try and isn't telling you then. And I bet you have as well."

"I'm not sure I have. I just really, really want to do his ass, but given that I've never done anyone's I'm not sure I'll even like it - perhaps it'll turn out like you and bondage: you try and then just wonder what the fuss was about."

"Well, there are ways. I could lend you Mark."

"What?"

"You can fuck Mark's ass with my strap-on. Just as a test."

"Er, I really don't think Nat would be cool with that."

"No? OK. How about mine?"

"What?"

"Oh come on, two women? Every red blooded male's fantasy?"

"I'm not gay!"

"Neither am I. Look, I could dress as a man, you do my ass, who's to tell what genders we are? You'd at least have a clue if you liked it, even if it wasn't entirely realistic."

"Er ..."

"I've got to say, though, there are two conditions."

"What are they?" Ha! I had her.

"First, it's got to be a thin dildo. I can't do large things up there."

"You should borrow Nat. Sorry, didn't say that. A thin dildo is fine."

"Has he got a small cock?"

"No, it's dead normal. Just my boyfriend before him had an enormous one, and the thought crept out. Ignore it, please."

"The second is weirder. You know I said threesomes? Well, yes, we've done them, and no that's not what I'm suggesting, but it's sort of related. Mark's cool with me doing anything with anybody and a strap-on. But the deal is that if he's not there he has a video of it. He thinks its the sexiest thing he has ever seen."

"You want a video of me fucking your bum so you can show it to your husband?"

"No vid, no fuck. Solid rule."

"Jeez, you two are complete perverts. OK, but I don't want the dressing as a man bit. That would be weird."

That was the weird bit? She's obviously more my kind of girl than I had given her credit for.

"OK. Plenty of light out here and it's totally private. Get stripped and I'll be back in a second."

I rushed into the bedroom and grabbed a camera, tripod, lube and strapon; I half expected that Annie would have had second thoughts and fled, but she was there, naked and inspecting her pussy.

"I should have waxed." She was worried about what she'd look like on camera.

"You look pretty good to me, but anyway this will hide any stray hairs", I said, handing her the harness and dildo. She looked fucking tasty to me as I took a few shots while setting up the camera.

She looked slightly bewildered at the harness, and they can be slightly puzzling at first, so I knelt in front of her to help put it on. Having the chance to inspect her closely I didn't know what she was moaning about, as she looked perfectly groomed to me - a little landing strip, but basically bare. Her pussy was already slightly damp, and I didn't think it was remnants of the shower.

I fumbled around putting the harness loosely around her, inserting tge dildo and tightening it up.

"Is it on your clitty properly?"

"I think so."

I grabbed the end of the dildo and moved it around, grinding it in to her, then looked quizzically.

"Yes. That's the spot."

"Now, if it was Mark I'd make him suck it a bit first, 'cos that really turns me on. But you've got to do what turns you on. Just pretend I'm Nat."

"Get on you knees and suck my cock."

I did. Sucking a strap-on is kind of weird; it's a far more a psychological turn on than a physical thing, but what's wrong with that?

"Deeper. Take it all in." In truth it wasn't a big one, so I could do that without much difficulty. I had my hands on her arse and pulled her into me, making sure that the end of the dildo was getting her clit properly.

"Harder, Nat, harder". I gripped it hard with my teeth and moved it around, trying to work out where she wanted it. I also pushed one hand up my cunt for lubrication then slowly moved it around her arse. She didn't protest, and in fact seemed to give a moan of encouragement.

A sigh. Had she cum? I thought so, and slackened slightly. After a pause, I looked up to see her smirking at me.

"Well done, Nat, good job. Now, over the table. I'm going to fuck the shit out of you."

"Be gentle?"

"I'll start gentle, but then I'm not holding back. Now stay there so I can point the camera at your sexy arse so your kinky sister and her husband can perve over you later."

"Can I put some lube on you cock?"

"Yeah go on, then I'll lube your arse."

It felt weird doing the cock, but then she firmly turned me over and lay me on the table, face down. "Nat, you have one sexy bum. Now rub you little cock while I'm doing this, but don't cum till I say." I put my hand on my clitty as she rubbed lube into my arsehole. Fuck, this was good.

After a bit I felt her fingers withdraw and the end of the cock enter me. She'd obviously paid attention to instructional videos of some kind, because she did it dead right. Slow and gentle at first, gradually going in deeper and harder.

"You OK, Nat?"

"Loving it. Do me."

She gathered speed, thrusting harder and harder. I don't know if she'd really meant me not to come, but I did, several times. Hard. Eventually she slowed down and stopped, and after a pause I felt her withdraw. I turned round and she seemed in a daze.

"Was it how you expected?"

"Fuck no. It was a hundred times better. Oh my god I can see why you do that at night and again in the morning."

"And then in the afternoon with my sister-in-law."

She giggled. I got some tissue and wiped down the dildo, then moved to unbuckle her, but she stopped me. "Hey, leave my cock alone. I want to see what I look like." She went into the house and stood in front of the full length mirror. "I look so fucking sexy like this. Why would he not want me?" I had to agree - she looked fabulous.

We sat in the living room - me still naked, her still wearing the strap-on and watched the video we just made.

"Show it to Nat."

"No. Really, he'd be a lot less pissed than if was Mark, but I'm still not sure he'd go for it."

"Let me show it to him?"

"You're kidding?"

"He listens to his big sister"

"Well, maybe, but surely you can't show him a video of us fucking and hope to get away with it."

"Bet you I can not only get him to watch it and enjoy it, but he'll rush home and demand you do him there and then."

"Or more probably he'll see his incredibly sexy big sister humping and forget that incest is a big no-no."

"Mmm"

"You pervert! I suggest incest and you just rub your cunt and say 'mmm' with a smile on your face. Would you really do him?"

"Would you mind?"

"If you can make him want to bend over and take my cock up his arse, then you can do anything you like to him as persuasion."

"You know I'd have to video it?"

"Send me a copy?"

"No, but you can come over and watch it with me afterwards"

"Perhaps we could try and re-enact it?"

"And Mark could video it for a proper professional job?"

Fuck yes. This was going to be good.
