Girly Boy/Rub one out quickly in the shower
From Create Your Own Story
This time, you decide to give in to your lust. Hell, you've managed to restrain yourself earlier, no chance you can do it again! The soap is making your skin all slippery, and you're already excited big time: that's why you start at a quick pace, wanting to get this over quickly. Again you think about those porno images, those gorgeous babes sucking and fucking those big, magnificent cocks, imagining yourself now as the man, now as the woman... it doesn't take long until you're ready to blast.
Jacking off at a furious pace, you are about to unload when your sister Kelly, not hearing the shower run, opens the door and enters the bathroom with only her panties on. "Who is there? Josh, is that you? Mind if I start here while you shower?" she says, just as you lose it and cum hard, several heavy spurts hitting the shower door and the wall. You're not able to speak for several seconds, so she asks again. "Josh? Are you alright?" With a trembling voice you answer, "Y-Yes, I'm a-almost finished h-here." She can surely sense you're not your usual self, and probably imagines what you've been doing, because a minute later, after you clean up and exit the shower, she gives you a dubious look while brushing her teeth. You don't say anything, she looks at you again but just enters the shower so you do what you must do and run off quickly.
You get back into your room, put on shorts and a tee and head downstairs for breakfast.
