Musical lesson

You pull open the drawer and peek inside. There is the usual stuff you would expect in there, but also some dusty things that were put in there and likely forgotten. One of them is a wooden double maraca. You have no idea how this peanut-shaped percussion instrument ended up here. You take it out. It is just 8 inches long, but it has two rather bulky heads.

"You always said you are very musical, big sister," you say.

Your sister raises her head and her eyes widen in shock, realizing what is in your mind. She can't escape in her hog-tie, as you turn over to her, comfortable in your seat. Although it was not long ago that you stretched her with your rather large cock- and the Maraca has a very smooth surface-, the big end of the instrument can't enter her pussy just yet.

You have to help with your fingers to **** it in. Once as it has passed her lips, you can move it better, going in deeper. The diameter on the thickest part is about 3 inches, while the slim part in the middle is just about one, so it glides deep into her after the first stretching. You feel her squirming as you fuck her with the double Maraca, and even through her taped mouth her painful moaning is quite audible. You feel hard again.
