I entered Pippa's bedroom where she had changed into a bathrobe.

"That was your mother. Your gran's fine but she'll be staying with her for a few days to make sure. I promised her I would look after you two until your father gets back".

"Well you've done a good job so far. My nipples and ass are sore and I've still got your cum oozing out of my ass and down my legs. See." With that she turned and raised her robe showing her sexy ass with a small rivulet of white liquid making its way out from between her cheeks. "Nice sight ? It certainly feels good."

"My pleasure. We will be heading back to my house to stay until one of your parents return. However, a few rules. I intend to continue our little setup, and Becky's education. She shows plenty of promise but needs to expand her horizons alot. I'm going to need your help in that. Also I hope we can repeat our little performance of this morning. You were one hell of a fuck, and I'm looking forward to tasting and experiencing your pussy"

"I think I can agree to that. I haven't been that well ass fucked for ages, and I think Beccy could learn to enjoy it too."

"I do hope so, and a few other things as well. So who else has fucked that pretty ass of your here. It was obvious that you'd done that before, even to the half used tub in the bathroom."

"Oh the tubs mummy's, not mine" she answered casually.

"Margaret's ?" I asked stunned. "I didn't know Dave was into that."

"He's not, she uses it with her lovers"

"LOVERS ! Margaret !" I was shocked. As my late wife's sister I expected her to be as loyal to Dave, as Anne had been to me.

"Oh daddy's too busy chasing his secretary Gill. Not that he's succeeded in catching her. Not surprisingly since she prefers women. In fact we've made love here, she's even fucked my ass with a strap-on dildo, although she doesn't like taking it herself."....(cont)
