You look back over at your younger siblings, both of them clearly embarrassed at this entire situation. Aaron seems to be suddenly body-shy to an almost cute, but also frustrating extent. Meanwhile, Missy is naked while Aaron is not, and that seems to be making her rather self-conscious as well despite you being naked as well. You do catch though that she can't seem to take her eyes off of your engorged cock.
You let out a sigh and throw the shower door open. “All right, fine,” You say. “I guess Aaron doesn't want to take a shower with us. You then turn a happier expression towards Missy “Missy, come on, you want to hop in with me?”
Missy looks back over to Aaron, and then she gives something that almost looks like a shrug before taking several uneasy steps toward you. Uneasy, but not hesitant. It is clear she is still a bit off about the whole scenario, but she almost seems glad to be doing what you tell her to, as though getting in the shower with you might make this situation seem normal again.
“You coming Aaron?” You ask as you step into the shower behind Missy. This seems to jar Aaron out of his stupor and he quickly strips off his PJs and follows behind with a slightly more confident version of the approach Missy had. Well then, it looks like you succeeded. Now you have got two naked younger siblings, your cute ginger six-year-old sister with freckles all over her face and tanned arms with her torso left pale-white like a swimsuit. This has a rather fun effect in the way of emphasizing the region between her legs just a little more as the white becomes a vee at the junction of her legs that seems to be pointing directly at her little child sex. The other is your girly-looking little brother. Once again, you are taken by just how sexy he looks and you have the strangest feeling come over you in regards to his young body.
'Damn it, I'm not gay!' you tell yourself in your mind, but you just can't help how much your little brother's body seems to be appealing to you. Of particular note is the fact that his little four-inch skinny stick of a penis is pointing straight out from his body. That thing looks incredibly cute, you just want to see it splattering his little boy cum all over the place.
'So, where to start?'
