You make sure Trish gets what she wants

You feel nervous, giddy with excitement, fearful and **** all at once. When Nathan takes Trish by the arm you add a little jealousy to that list. You knew your girlfriend slept with men, but this is the first time you've seen her looking that way at a guy. Paula intertwines her fingers with yours, startling you. "Come on," she whispers, pressing her hip against yours, "I can show you my room."

You look up the stairs, where Nathan has started leading Trish. She looks back at you, but for once she seems at a loss for words. It feels strange. Not as strange as it will feel for Nathan if Trish decides to give him a demonstration of why she's a very special girl. You have no idea how that would work out - it could end with Nathan running screaming, it could end with him, like you, learning something he never knew about himself.

But tonight doesn't have to be the night to chance it. You let Paula lead you but, loud enough to be heard by the other two, you ask "Is your bed big enough for all of us?" You cringe a little at the amount of emphasis you put on 'all', but the three of them are more drunk than you are. You even get to see the quarter second delay before Paula's eyes look at Nathan and Trish, then back to you.

"Um, but don't you want to...?"

You let Paula know you find her plenty attractive with a long, slow kiss. Your fingers find the clasp and, with more practice than most men, you undo it and run your hands up and down her spine. When you finally pull back slightly and break the kiss Paula is panting. "Oh, I want to. I want to do all sorts of things tonight." With that you give her a grin and look up at your companions.

Trish is grinning back wolfishly, her hand wrapped around Nathan's waist and resting on his manhood. He deserves a show, you think. Sensually, you remove your own bra and twirl it on your finger. "Do you have room for two more?" you ask in your most girly tone.

"We can use the master bedroom" says Nathan.

Paula winces and starts to say "That might not be such a good..." but you interrupt her again, this time with a hug that plants your free and frisky tit flesh against hers. "Live a little," you say as you gently slide her bra straps off her shoulders.

Once Paula's motor is running she stops arguing and starts helping. She whips most of the covers off so she can re-make the bed later, then she wriggles out of those Jeans faster than Trish can get out of hers. You can feel the breeze, of course. Not wearing panties does give you that advantage over them. Instead of slipping off your last scrap of clothing you use the time to unbutton Nathan's pants and whip off his belt.

He laughs happily, just as you would if an eager young woman was fighting her way to your junk. He surprises you by putting his palms on your shoulders. "Hey Jane, not that I don't love this, but Paula's had her eye on you for... since she met you."

Sure enough, as much fun as Paula and Trish are having right now, you see them both looking your way. Damn it's hard being the hot one! Deep down in the pit of your stomach you feel that desire to please Trish. Yes, it's just some magic or **** or something, but you don't really want to fight it right now. You know that Trish wants to spend herself inside Paula's tight little pussy and you are going to give her that gift - cause you are the best girlfriend a girl could have.

You smile back at Paula, then run a finger down Nathan's chest, over his nice abs and to the band of his underwear. "Oh, I know. I've been looking at Paula all night too. And I really want to play with her. But the thing is... it's been a long while since I had a nice hard cock. And I'm so horny that I'm getting greedy. Yeah, I want both."

That gets a confused look from Nathan, till you grab his wrists and pull him over to where Paula and Trish are. "Baby," you say to Trish, "you know how needy I am. Pretty please, can I do something very naughty? Can I get both my itches scratched at once?"

Trish is smiling like a maniac, so she must have caught on. "Oh God, how did I wind up with such a crazy, sexy girlfriend?" she asks. "You know you've got me wrapped around your finger, so do it. Show off what kind of girl you are to our new friends!"

You giggle and wrap your arms around Paula. "Hi beautiful, can you lead the way?" She eagerly picks you up and carries you to the bed. You give her a long, tender kiss and then crook your finger Nathan's way. Trish is whispering something in his ear while she rolls a condom onto his quite impressive cock. His eyes look glazed over and he's smiling to himself until your finger snaps him out of it.

That's him taken care of, you think to yourself as you feel a weight settle on the bed behind you. You concentrate all your attention on Paula - your now talented fingers don't go straight for her clit, they sweep smoothly over her flat tummy, her firm mounds, her hot neck - which gets less and less tense as you gently tease her. You lips seek out her shoulder, her ear, only then going back to her mouth where you find a tongue as **** as yours.

You pull her close so your nipples can press against her soft skin once again. Then you feel Nathan's hands wrap around your waist. To mess with Paula a little you take her hands and press them firmly on top of his. She lets out a happy little moan and you know that Trish is doing something to her. Nathan doesn't have his hands free, but he does have one stiff appendage he can move and he uses that to lift the back of your short skirt a little higher.

"Mmmm, yeah!" you moan into Paula's mouth. Nathan's cock grinds between your thighs a few times, that condom feeling very heavily lubed up. Most considerate of him - not that you need any lube right now. You feel a hand reach down, obviously Trish, and you smile. Right up until that hand guides his girthy manhood to your sphincter.

"Such a lovely, dirty girl" says Trish as she uses her other hand to pull your cheeks apart. Nathan takes that as his cue and starts feeding your rectum inch after inch of cock. You squirm a bit, but with all three of them holding on plus the copious lube you're betting Trish applied you are firmly impaled in seconds.

"Ohhhh!" is all you can manage after that. It's not Trish's cock, but she has been training you to enjoy getting you ass filled.

"Here," says Trish, taking one of Paula's hands and feeding her fingers deep inside your pussy. "Do you feel that?" she asks as Nathan begins to slide back. She kisses Paula's ear and whispers "That's your brother's cock thrusting in there. Isn't it neat the way you can feel that? Isn't this what you've wanted for so long, Jane?"

Paula doesn't know what to make of it, but as Nathan starts to slowly fill you again you catch Trish looking deep into your eyes. All that lust in your belly seems to boil up and you grab Paula for another kiss. If Trish wants this then you want this. You suck the air out of Paula's lungs and say "I'm sorry I'm such a naughty girl. I've always wanted to do this - I must have begged Trish aaahhhh dozen times to let me, ummphh, have some sibling love!"

With that you cum hard. You know that Paula feels it - how could she miss it with three fingers jammed inside your pussy? Nathan must be loving it too. When you finally come down you moan to yourself "Ohhhh, never could do this with my family."

Paula is grinning ear to ear. Whether she had some desire for this before or whether this is brand new, you know that fucking the stuffing out of some girl with her younger brother is definitely on the menu from now on. And then you see a look cross her face: Surprise. You know what that means and draw her into a long and passionate kiss. Neither you nor Nathan can see anything, but your questing fingers feel the telltale bulge below Paula's clit. Trish's trouser snake has been revealed, but with some careful kissing and clit polishing from you the horny sister is too lusty to do anything but start moaning harder.

The thought of Trish fulfilling her desires and pumping a thick load of cum inside Paula combined with the rather pleasant pace Nathan is taking reaming your ass leaves you struggling to hold yourself together. But you do hold long enough. When you tilt your head back and moan as your thighs quiver Paula starts sucking on your nipples. Clearly she's decided that this unexpected cock is not unwelcome.

When you hear "Mmmm you're sooo sweeet!" from Nathan as he kisses the back of your neck you know that your ride is coming to a close. Trish doesn't take much longer before she whispers "I love you" and you feel her seed being **** from her overfull balls, up that fantastic shaft and into a waiting womb. She may have whispered into Paula's ear, but it was your eyes she was staring into.
