Too late to stop...

Grinning, you allow Amy to rapidly undo your zipper. She yanks your pants down over your hips, rapidly followed by your briefs. As she does this, your cock springs out even with her face. She looks at it, smiling softly.

"MMmmmm, John, I can't wait to have that inside me," she pants, sliding her hand up to stroke along your shaft. The contact sends ripples of pleasure up your spinal cord, as you quickly kick your pants free of your ankles.

Amy runs her tounge along her upper lip, and lies back on the couch, her hips pumping toward you. Sliding your shirt off, you lean forward over her body, running your hands along her stomach, pausing briefly to massage her breasts gently. The motion causes your throbbing erection to run along her thigh, and she groans at the contact.

"Yeah, that feels so good," Amy groans. "Put it in, please!"

"All in good time," you grin at her, and slide a hand down to grasp your pulsing member. You proceed to slide your cock over her thighs, her crotch, everywhere, except her pussy. She's wiggling her hips, and trying desperately to capture it, but you resist the desire to just bury yourself inside her.

"Stop teasing, big bro!" Amy scolds you. "Don't you want to fuck your sexy little sister?"

With that, you slide your cock to her pussy lips. Taking your time, you stroke your cockhead up and down her pussy, rubbing gently at the lips, parting them slightly. Her excitement lubricates you both, and you feel her pussy quivering in expectation. Finally unable to take any more, you move to the entrance to her body, and slip the head of your dick between the folds.

Her reaction is intense, and her legs come around you to attempt to pull you deeper, while she attempts to pull you down onto her. You resist, and drive a little deeper, feeling her extremely tight pussy clamping hard onto your cock.

"More... Please..." Amy wails, totally lost in the experience. "Deeper, John, Deeper!"

You ease your chest down onto her breasts, your hands coming around to grasp at her waist. You push your cock further into her body, her pussy swallowing another inch or so. The feeling is intense, when suddenly you come up against a barrier.

Your eyes widen as you look into your little sisters eyes, as she gasps and moans agains you. She's still a virgin! When she said she was saving herself, she really meant it.

Amy notices your hesistation, and her legs come around you to pull you against her. Your cock is stretching her hymen to the breaking point, and another movement would deflower her. She seems to sense this, and nods at your questioning gaze.

"Yes... Take me." With that, her hands come down to your buttocks, and pull you forward. Your cock pauses once more, then rips past her virginal barrier, sliding deep within her body. Her back arches in response as you deflower her, and she bites down on your shoulder. She shudders, and her pussy clamps onto you just as hard as when you made her come on your tounge. Your little sister apparently is a little kinky, and is enjoying the slight pain.

"Oh god. Yes!" Amy exclaims, and with that, you both begin to move against each other. The feeling is incredible, with her arms and legs urging you on, and her pussy accepting you totally. She winces occasionally, but the pain just seems to be a sexual spice to her, enhancing rather than detracting from her pleasure.

Several minutes go by, with you lost in each others arms. You continue to make love, your bodies fusing in an incestuos embrace. You feel yourself reaching for orgasm, getting closer. Your pace increases, and you and Amy both look down at your fused crotches to watch your naked cock plunging in and out of her. You're so close.

Naked cock? You look down and realize that you failed to put on a condom before you went inside her. With your little sister a virgin, the chance that she's on the pill is very slight. You continue to move, and your coming orgasm grows.

Amy notices it too, and her eyes grow a little nervous. She looks into your eyes, and nods. Whatever you want to do will be okay with her.

Should you pull out and put on a condom before continuing, or just finish inside her?
