Play with her titties...

Your sisters naked body stands on display before you as you eye every inch of her hungrily... Your hands wander first to the soft large mounds of flesh on her chest, and you rather roughly begin to carress them, kneading and squeezing, pinching and pulling on them as you revel in the pleasure of your new plaything... You kneel down amd take one of her soft nipples into your mouth, gently sucking on it and swirling your tongue around it, eagerly taking your time while you pleasure her tit with your mouth... You hear her breath quicken, telling you she's awake... That thought alone emboldens you, knowing that she's okay with being your little toy, your plaything, as she pretends to sleep...

You begin to gently nibble on her now hard nipple, and try as she may, Sarah can't keep her tiny moans of pleasure hidden any longer... You take your time with her, going back and forth between licking, sucking, and biting on her delicate nipples...

Your hands begin to roam down her soft skin... Close and closer to her slit...
