Fine, what's the worst that could happen

After giving it a brief consideration, you eventually exhale and nod your head. "Yes sure, just be careful." It's better to have him on your side, than to risk having him spill your secret to everyone. Since he just came anyway, he wasn't going to shoot off again anytime soon. You can feel him moving a little closer up against you, his chubby belly made it anything but easy for the overweight boy. Considering how good your body looks, he was probably excited beyond belief to have this chance.

Upon feeling his appendage on your inner thigh, you quickly reach for his nightstand to grab a tissue. "Hold on a second," you demand as you reach under the bed covers, grab the shaft of his rod and begin wiping off all the icky remnants of condom lube and sperm. That was way too close for a second, as you realize your mistake. "There, now it's good to go." Just to be sure, you let your fingers run from the bottom of his cock up to the tip - clean and dry.

He's beginning to move his dick upwards and fumbles around a bit, not quite hitting the mark, so you assist him and guide the tip of his cock right up to your subtle vagina and between the meaty folds of your cunt. It was then that he hesitated, as if having second thoughts upon remembering something. "Come on, bro. Chicks hate it when the guy is shy. Here, lemme help," you offer as you slightly change the angle of your hips and begin pushing back against him.

Torn between emotions, your brother remained silent. He had to choose between putting a stop to it, or getting to enjoy the naked embrace of a real pussy even if it meant letting his "brother" inseminate himself.

Underneath the bed covers, your pussy lips began to part lightly to start making room for your brother's cock. In the process, those pursed lips also began peeling back his foreskin as maybe a quarter of his cockhead was inside you. Your female genitals were preparing to take a real man inside. And then, without wasting more time, you simply thrust your butt backwards and take in the first few inches, including his now fully exposed glands with the batch of slimy sperm that had been tucked away under his foreskin - now free to roam within you. Enough to pose a risk.

Still completely unaware of the delicate situation down there, you begin rotating your hips lightly to give him a better idea of what it feels like to be bareback inside a young teen's vag, completely focused and determined to make him feel good so that he would be like clay in your grasp. Unfortunately that also causes his cum to further smear around inside of your pussy, giving your interior a fine coating of virile semen. When you eventually pull back again and have his member slipping out of you with an audible pop, he's still looking stunned and speechless.

"What's wrong? Thought you'd be more happy." Just to be sure that there was no accident, you reach down, slide a finger into the tight comforts of your cunt and wriggle your digit around a little. Warm and pretty lubricated, but that's nothing unexpected. Just a typical pussy. The small trace amount of sperm that was now coating the inside of your vagina went completely unnoticed.

Did he not enjoy it? Lowering your hand a bit more, you touch his erection - he was rock hard. Whatever he was thinking about, seemed to turn him on at least.
