Me and Susan got very close in the coming days and we never let a chance to fuck go waste. We made love in the morning when Susan woke me up by sucking my morning wood in the car on our way back home, at home when Margaret was at work and finally at night before we slept in each other's arms.
It was after month since we started our relationship when Margaret confronted us at breakfast.
"I need to talk to you both" she said giving both of us cold looks, she waved her hand signaling both of us to sit.
"Yes mom?" Susan asked innocently.
"It has come to my notice that both of you have been sleeping in the same room for a while now and I presume doing more than just cuddling each other in the bed?" Margaret said glaring at us.
Neither of us replied, our nervous silence telling her everything.
"I am utterly disappointed in you both!" Margaret snapped at us angrily. "How could you two be so irresponsible!?"
"I can explain mom..." Susan said but was quieted by Margaret with a wave of her hand.
"You!" she said pointing a finger at me then continued, "Do you really love my daughter or is it just lust for you?" she asked me.
"I truly love Susan and I have loved her since the moment I met her. I promise that I will never hurt Susan intentionally or unintentionally." I said surprised with myself for coming up with so dramatic sentences. She glared at me for a moment longer before turning back to Susan.
"What about you?" Margaret asked Susan.
"I feel the same for Ralph and I cannot bear to live without him." Susan answered with teary eyes.
"Well if this is the case, I have no problem with it." Margaret said her face twisting into a smile. My heart stopped, barely able to believe she agreed so fast.
Susan ran and hugged her mother as both women wept into each other's arms.

Later that night when Susan and I lay in bed, she asked me "Do you really love me?"
"Truly, deeply and madly" I replied, pulling her into a very tight embrace.
That night we made very slow and passionate love unlike our previous fuck sessions which used to be very wild.
The next day both was the first day of summer break and when me Susan went down from breakfast we found a note from Margaret saying that she had to urgently leave for Washington for an important case and she would be away for at least a month.
"Do you know what this means daddy?" Susan asked me with a wicked smile.
"Yes you dirty little girl" I replied as I kissed Susan hungrily and my hand went under her t shirt massaging her breasts.
She then pulled down my shorts freeing my raging hardon and started stroking it as I lightly fingered her pussy. I made Susan sit on the couch as I dug my head between her legs to eat her out. As my tongue delicately worked on her clit , circling her pussy her moans started getting louder and finally after a few licks on her g spot she came hard releasing her juices into my mouth.
We switched positions and Susan engulfed my cock in one go , her tongue working in magic ascending me to the pinnacle of ecstasy as I climaxed into her mouth as she kept on sucking me to get me hard again.
Once I was hard enough she got and removed her t shirt revealing her heavenly tits.
She leaned against the dining table and motioned me towards her saying "I want it up my ass daddy."
As I went up to her I asked "How do you want it, you dirty slut?" as I spanked her ass.
"Hard and fast daddy!" she squealed with a mixture of pleasure and pain.
