Get her to sit up...

"Sit up," you say, your voice hoarse and your lips dry.

Your sister does exactly as you wish. Silently she sits up. The covers of her bed fall aside and pool on the bed behind her. She has her back to the wall. Her legs are over the bed and her feet touch the ground. Your sister has amazing breasts. Her tank top wraps around her chest, below her boobs now - thanks to your command - and pushing them up for you to see. She looks gorgeous.

You can see her better now, now that she is sitting straight. Your sister does not sleep in touch. Small black panties cling to her hips and for a long minute your eyes lower to her legs and crotch. She earns a living making sexy underwear look great... no wonder she looks great in her own sexy panties.

Slowly, slowly, your eyes return to her voluptuous breasts. Perfect.

It is then that you release that your right hand has dipped beneath the waist band of your own underwear. Your cock is hard between your fingers.

You just -have- to do it. You -have- to. It is with growing confidence that your sister will remain asleep and under your power that you slowly pull your underwear off.

Naked and erect you stand before your sister. Your cock is just inches away from those perfect breasts. Your dick could touch those perfect nipples.

Thoughts flash through your mind. Images. Ideas. You can almost imagine what it would be like to kiss your sister now. You can almost imagine what it would be like to kiss and suckle on those wonderful tits. You can almost imagine what it would be like to jack off in front of her like this. Oh... you can almost imagne what it would be like to jack off on to her. A hot shudder runs through your body.

You could do so much with your sister right now.
