Let's go for a triple

"It's your own fault for showing off like that," you say as you grab her hips and pull her over to you. You see her grin at your initiative and wiggles a bit to egg you on. You rest your cock between her cheeks and slide it in and out a few times before sliding down to her pussy. You slide in easily and thrust a few times until you're sure you're well lubricated before you pull back out. She looks back over her shoulder and gives you a confused look. Then her eyes widen a bit as she feels you pressing against her tight little asshole. You give her a sly smile and ask "how's this hole?" She seems a bit nervous as she responds, "I've tried it a few times, but I'm not sure if you'll fit." Your disappointment must have shown on your face because she scrambles to say, "it's okay, you can try. Just please be gentle."

She spreads her legs a little and you can feel her relax her sphincter in preparation for what's to cum.  You gently move your hips forward adding a little more pressure against her ass.  Finally, it starts to give a little as you see and feel yourself slowly sinking into her.  You manage to get the head inside and she takes in a sharp breath.  "You okay?" you ask.  "Yeah, I've just never had such a big one in there before.  Keep going, I wanna see how deep it feels."  With that said, you press on getting deeper and deeper until you feel your balls rest against her pussy.  You can feel her muscles tighten, trying to push you out but that just intensifies the sensation.  Her ass has such a vice grip on your member that you're surprised you even got it in.

Hinako has her face buried in a pillow and she's panting pretty hard.  Whether it's from pleasure or pain you can't tell.  Maybe you went a little too far, but it feels too good to stop.  Maybe there's something you can do to make her a little more comfortable.  You bend down over her until your chest is almost touching her back and reach a hand between her legs seeking out her clit.  You find it and give it a little stroke, causing her ass to spasm around your cock.  "No reason we can't both enjoy this," you say as you finally start to pull out, stopping when just the head is left in her before sliding back in.  This combined with the attention you're giving to her pussy causes her to moan, this time you're sure it's in delight.  Pretty soon you've got a good pace going, thrusting forward into her ass while you finger her drenched cunt.  Hinako is doing her part as well, tightening her ass as you pull out and relaxing as you go back in.  You feel her hand meet yours at her pussy, "haa. . . haa. . . I'll take care of this. . . UNnngggg!"  You move your hand back to her hips and increase your speed as she takes over working her own nub.  She's getting pretty into it now and is propping herself on her elbow using her free hand to bring her breast to her face.  She's practically drooling now as she clamps her lips over her own nipple and sucks like her life depended on it, stifling her moans a bit.

You're in heaven, pounding into her ass making wet slapping sounds every time your hips meet.  Finally, you feel your climax coming.  You grab her shoulders and pull her up, causing her nipple to slip from her mouth.  She's practically screaming now as you jackhammer into her, pulling on her shoulders to slam her back down on you.  Suddenly, she convulses as her orgasm hits her causing her to clamp down on your cock.  She's so tight now you can't move anymore, but that doesn't matter as you've already reached your limit.  Your cock does its best to release, but she's clamped down on you so tight you can't.  Stars flash in front of you as your orgasm is prolonged, your pulsing member trying futilely to shoot your wad.  Finally, Hinakos orgasm subsides and she loosens up.  With a roar, you unleash everything you have into her, filling her bowels with your seed.

You pull out your quickly softening member and collapse next to her, completely spent.  She rolls on her side to face you, a tear streaking down her face.  You wipe it away with your thumb and give her forehead a light peck, "sorry about that, I tried to be careful."

She shakes her head and smiles, "Don't apologize, that was amazing.  It hurt a little at first but then it felt really good.  I've never cum from anal before."

"That's because you've never had me before," you say, mentally beating your chest in triumph.  She rolls onto her back and rubs her belly, "I can still feel your warmth in me.  I don't think I'll be able to walk straight for awhile."

"Good, now you can't escape me," you say with a devious grin and pull her into your embrace giving her a deep kiss on the lips.  When you separate she gives you a dreamy look and says, "we are sooo doing that again."  You're shocked but are relieved when you realize she doesn't mean this very second.  Once was more than enough for one night.  With that, you pull the covers over the two of you and lie naked together in each others arms, basking in each others warmth as you drift off to sleep.
