My god, She had changed so much in just a few weeks she was quite shy before but now she had transformed into a nymphomaniac.She lay back on the bed, ...er legs lifted into the air displaying her delightful pink pussy. “Come on then you know what I want, lick me like you've never licked me before and I might be nice to you.”It wasn't easy with my hands still tied to go down on her and keep my balance, but I managed, I traced my tongue along her slit, my god she always tasted so good. My tongue. She sloppily kissed me and almost run back inside."Where have you been?" hissed my sister."Just outside getting some air," I said."Have you been perving with one of my friend?" she hissed."Yeah, but only one," I laughed."Who?" she asked, looking around to see who was missing."I don't know," I said, "didn't get her name."She looked at me for a long time then laughed."You're kidding right," she said and moved off.It was very late before everybody had gone and the mess was cleared away."We're off. “Don’t you get it? There’s nothing to see in space,” she explained with her usual sassy, know it all attitude.Emma made a move to slap her older sister. “Don’t call me goofy, it’s not a nice word,” she sniped at her older sister.“Yeah, but if the shoe fits, wear it,” Holly laughed at Emma. She stood five foot three, weighed 120 pounds, and had a body that already boasted big, youthful breasts that stuck out on her chest like twin torpedoes, long, slender legs and an ass that would make any. Perfect, just like my girl's ass, early morning inspiration."Good morning my love," I returned her greeting then seeing the tray, "you may place the tray, then get your perfect ass up here besides me, my girl." Ever eager, ever obedient, she placed the tray carefully before me then did a kind of slow motion leap that ended with her kneeling besides me, her knees spread, the locket glittering in the sun that poured through the window, "relax sweetheart, and don't move." My girl looked at me.
