Her rich uncle died

I gently lifted my mom off my cock, her frail form still almost unable to move from the gigantic orgasm she had just received. I took her into the living room and laid her on the couch, letting her get her strength back.

I turned to leave her, but she gasped after me "No, Timmy, you should hear this. Get your sister." From her tone, it sounded important, so I closed my robe and went upstairs to tell Kate to come down as well.

5 minutes later, after my mom had caught her breath, she looked at us both very seriously. "Timmy, Kate, that was my uncle Davids solicitor. They've just informed me that they've finally found his will after he died last year. And he left us his house."

Both my sister and I were dumbstruck by the news. My great uncle David had owned a major pharmaceutical company, and his house had been gigantic, a real mansion just outside of town. An extravagant palace that seemed to have everything. We'd only been there once, when me and Kate had been much younger, back when our great aunt was still alive. I couldn't imagine what my Mom had done to get us back in his good graces, but I sure was glad she did it.
