You break your one rule.

You turn to your brother. He is the only person you love. Mum and dad don't give either of you any attention. They only care about their careers.

Sam though has always been there for you. Born 10 minutes before you and so much taller than you, he has always been big bro, and you little sis.

When You turn around and press yourself against him Sam stiffens in surprise. You always had the rule that any sexual experimentation is limited to you giving him a hand job or him fingering you tiny pussy. Now you are pressed against him, naked and vulnerable. Looking up at your loving brother you get up on you toes and kiss him on the lips.

You feel his arms wrap around you and pressing you against him. Opening his mouth Sam kisses you back and you feel his big tongue inside your mouth.

Bringing your arms up to wrap around Sam's neck, you feel your small breasts squash against his toned body.

As you hold on to Sam and kiss with a desperate longing born of desire long denied, you feel his hands slide down your body and come to rest on your ass cheeks. Seemingly without effort you feel yourself lifted off the ground by Sam's strong arms.

Wrapping your legs around your brother's waist, you pull closer and kiss him deeper. Taking advantage of your now even mouths, you bury your tongue in Sam's mouth, moaning in desire as you feel his rock hard cock, press against your folds with only the thin material of his shorts between you.

Without warning Sam pulls away and looks at you questioningly. “You sure you want to do this little sis? He asks and you blush and look away in return.

Looking back up and directly into his eyes you say yes and feel him crush you back against his chest.

You feel his lips on your neck. At that special spot that drives you wild. 'How does he know how to do that?’ You wonder as you feel big bro moving across the room.

You moans of desire turn into a squeak of surprise as you feel Sam throw you off him and experience a moment of weightlessness before landing on your back on the bed.

Levering yourself up onto your elbows you see Sam struggling to get his large hard cock out of his shorts. As you see them drop and Sam's magnificent tool is open for your viewing you beckon with a finger and whisper “Come here big bro.”

Smiling Sam crawls forward between your open thighs and your mouths meet once more.
