SIBLINGSThere was a soft knock on Micki's bedroom door followed by a whispering voice that asked, "Hey sis, are ya busy!?!" Micki put down her history book and replied, "Come on in, Mike, I'm just studying for quarterly final, what do you need!?!" Mike plopped down on the edge of Micki's bed and without even blinking, slid his hand up and under her bathrobe and began caressing the inside of her smooth thigh!!! "Hey, dummy," she whispered hoarsely, "what if mom or dad comes in, you wanna get us in trouble!!!" He chuckled quietly under his breath and replied, "Don't worry about a thing, they're already in bed fast asleep," while his fingers worked their way up her thigh until they encountered her panty clad pussy!!! "Well just the same," she retorted, "we made a deal that unless we were alone, we wouldn't take any chances!!!" I know, I know," he replied softly, " but jeez louise, just look at this," while standing up and opening his own bathrobe revealing a very firm erection!!! Micki looked at the door one last time, and making sure that neither of her parents were about before lowering her mouth to her twin brother's long fat cock!!! "Oh god, sis," he moaned, "you suck better than any girl I've ever had, I wonder which side of the family you get it from!?!" "She let his big pecker slip from her mouth before replying softly, "I don't know, but I'll bet it's from mom, I just think she loves sucking cock as much as I do!!!"
