Can't stop a run away train.

Without a word being said between you, you slide your finger out of Heather’s pussy and reach around, grabbing hold of Heather’s bum, picking her up in the air. Heather brings your cock to the entrance of her pussy as you press your hips forward, lowering her light frame down onto your prick. Heather’s hand claw into your back as she crosses her feet behind your waist.

Your cock is deep within your first ever pussy. The sensation of Heather slippery smooth pussy walls causing your dick to twitch as you experience an entirely new heavenly sensation. You press her against the wall and start to thrust your hips against her. Heather pushing her pelvis to you, meeting every one of your strokes. You let out a moan of ecstasy as Heather too groans at the delicious sensation.

You are making love to your sister right there in the shower and it felt like the most natural thing to be going inside her. You knew with 100% certainty that this is what she wanted. All the teasing and coaxing leading to this moment when you two siblings share the greatest intimacy.

Heather is an experienced lover and knows what to do. All you really have to do is hold her up and she does the rest. Even being suspended in the air, Heather is able to ride you. The rocking of her hips against your cock becomes faster and faster. Her pussy is so incredibly slippery it’s a shock to you. As her speed reaches a crescendo Heather begins to shriek loudly as she shudders her whole body. Her pussy squeezing and pulsing its silky grip.

Heather’s orgasm is way too much sensation for your virginal cock to experience so soon.

You moan urgently, “Heather it’s too much!”

Still slides herself along your pole a couple of more times before getting off ever so reluctantly. You are sure she was weighing up in her mind not getting off and just letting you cum inside her. The risk just too great as she lowers her legs back to the shower floor. She has to hold tight to you until she is able to bring her uncoordinated limbs under control.

“Let’s go to your room,” she says puffing, shutting off the water and getting out of the shower. Heather wraps a towel around her wet body as you likewise quickly dry off before flowing your sister to your bedroom.

“Put something on and it’s your turn,” Heather tells you as she climbs onto your bed facing away from you. Her hair damp and falling down over her shoulders. Still hard as a rock, you drop your towel and cover your cock with one of the condoms Heather gave you. You lift the towel up over Heather bum giving yourself a clear view as you step in behind her, able to stand on the floor with her kneeling on the bed.

Heather moans again as you slide back inside your sister’s pussy. Her hands bunch up big handfuls of the sheets as she lets you take control of things this time. You revel in the feeling of your dick inside her. The small break giving you some time to recover and delaying your spraying. Knowing Heather has come, you feel no pressure and can explore this new world of sex. You discover very quickly that going fast will make you cum almost right away so you have to almost stop for a moment, refocus and take your time.

Judging by your moans, Heather knows you are enjoying yourself immensely.

“That feel good brother?” she asks you as you tenderly fuck her.

“So good Heather,” you confirm your delight.

“You like fucking your sister’s pussy?” she continues.

“I love it!”

“Yeah you love your sister's pussy?” she moans.

“God yes I love my sister's pussy. Uhhh yes!”

Your sister’s words pushing you to your peak.

“You’re going to cum aren’t you brother! Your sister’s pussy has got you to cum.”

“Yes, Heather. Oh God, your pussy is making me cum. I’m cumming,” you yell as you start unloading inside her. All that big load caught by the condom as you pump your seed out inside. You pull Heather's ass back as you fuck yourself hard and deep inside her for your final orgasmic strokes.

Panting you slide yourself out of Heather enflamed pussy and see the pool of cum caught by the latex. Your virginity was gone. Your sister making you a man.
