You start slow.

Sam kisses you deeply and you kiss him back, feeling his rock hard cock resting against your delicate folds.

Wrapping your arms around your brother's neck you fall back onto the bed and bring him down on top of you. Pressing you down.

You feel big strong hands on your tiny little titties and moan into Sam's mouth as he pinches your nipples.

You squirm around under your brother in desperate need, feeling his cock move around on your swollen lips. Pulling back from your mouth, Sam smiles down at you and whispers “Let me help you with that.”

Sam pulls back and starts to hump his giant tool against you, applying pressure against your little button.

You cry of pleasure is drowned out by Sam's mouth and you buck against him, seeking more pressure.

Sam seems to know better though and continues his torturously slow pace. You feel your pussy grow slick with your combined juices and your lips open to allow Sam's cock into your channel.

As your brother continues to grind against you he pulls back from your mouth and looks down at you. “Do you have a condom?” He whispers with need in his voice. Your lips are burning and your voice is gone from the intensity of your kissing so you just shake your head. “Fuck!” He mutters before pushing his cock hard into your clit and sliding through your juices.

This is sexy as hell and you definitely will get off from the attention your little clit is getting but you want to be knocked up by your brother. Spreading your legs even wider you tilt your pelvis to give him better access to your honeypot.

Sure enough on the next stroke, Sam's cock catches at your opening and his head stretches you open. Looking down your brother looks at you with a question in his eyes. You smile up at his and whisper “Maybe just the head? But please be gentle. It's my first time.”

Sam looks surprised and replies “But all those guys chasing you. You don't sleep with any of them?”

You just shrug and reply “They weren't you.”

As Sam starts to gently fuck his head in and out of your soaking snatch, you feel the walls of your canal start to open to him and the sweet pleasure of being gently fucked by your brother fills you till you don't think you can take anymore.

As Sam bend forward to kiss you again, you feel his cock start to press in deeper inside you. As you reach up to press your hands against his magnificent body you feel his hands again at your breasts.

As your brother continues to test your limits, you pretend to not notice that he is now over halfway inside you. Kissing him tenderly you let him set the pace as you revel in you long denied desire fulfilled.

As Sam bottoms out inside you and you feel his heavy balls rest against your ass you look up into his eyes and wink.

With an animalistic growl, Sam starts to fuck you faster and harder. While before he was tender and loving, now he is hard and demanding.

You try to give as good as you get, kissing him back as hard as he gives but your rising orgasm saps your focus and strength.

Sam seems to sense your closeness and he adjusts his angle so that his pubic bone crushes your clit with every drive.

You cry out in exquisite pleasure and cum, calling out your brother's name.

As you come down from your orgasmic high you feel Sam tense and his cock pulses inside you. At the same time a wet heat fills your core and you know that he has filled you with his cum.

Collapsing on top of you Sam gasps between breaths “Sorry… I couldn't… your pussy was squeezing me.” But you shush him and hold him close.

After a minute Sam climbs off you and pulls a blanket over the two of you. Pulling you up close to him, he spoons you and you revel in the smell of your big bro. Sam kisses you on the ear and asks “Hey sis. You're not on the pill, are you?”

You whisper back “No.”
