This is the forth part of my cocksucking college sister series. Here is a brief summary of each previous part.

Cocksucking College Sister: Fucked
In the third part, it is later that evening at their parents' anniversary when the two siblings finally cross the final taboo and have sex with each other as Anthony takes his sister's virginity.

Quick reminder of the ending of part 3:
While dancing with his mother, Anthony is shocked to learn she knows about him and his sister; he is doubly shocked with the words:
"So Anthony, do you want to fuck Mommy?"
Cocksucking College Sister: Mom & Dad
Mom let her shocking question linger in the air for the remainder of the song.
My head spun with the double revelation that:
1. Mom knew about Lilly and I having sex and was not outraged by it.
2. Mom had just asked if I would like to fuck her.
My cock was instantly at launch and ready for takeoff mode at the thought of fucking mom. She had been a constant stroke fantasy throughout high school by myself and all my buddies who called her a MILF. Unlike my shy sister who had always dressed rather conservatively, hiding her nice body, mom had always dressed provocatively but classy (if that is a combination that makes sense). She had always been a dress or skirt type of woman and my obsession with nylon legs definitely began with her. I remember sneaking into her room as a teenager and using her pantyhose to masturbate myself, envisioning losing my virginity to her. My head was spinning at the possibility of making my longest running sexual fantasy a reality.
Just as the song was nearing completion, I felt Mom's hand on my cock as she whispered in my ear, "Are you hard because of me?"
My cock flinched in her hand as all I could do was whimper.
"I'll take that as a yes, Anthony," she purred.
"Oh God Mom," I barely got out.
"I have to cut the cake and dance with your father but I should be able to disappear for a few minutes in about half an hour," Mom explained, looking completely insatiable.
"Are you serious?" I asked, even though her hand firmly on my cock there on the dance floor was a pretty good indication she was.
"I plan to show you just how serious I am as soon as I can disappear from my wifely duties Anthony. I have never been hornier than I was watching you fuck your sister," Mom answered, giving my cock one last squeeze.
"Meet me in the wine cellar at 12:15 is that understood?" she asked, like she would when she was laying down the law when I lived at home.
"Yes, Mom," I agreed, still unable to fathom the reality I was currently living.
"Good," Mom smiled as the song ended. Pulling me in for a hug, her breasts firmly pressed into me, she whispered, "Now don't you be late son."
Before I could respond she was gone, and the massive tent in my pants was no longer obscured by mom. I quickly moved to a table and sat down giving my cock time to settle down and my brain time to process what had just transpired.
I was alone only a minute when Lilly joined me.
"You ok, big brother you look completely frazzled," she asked, stressing the word big flirtatiously.
"Dazed and confused," I joked.
"What's going on?" Lilly asked suddenly worried. "Did mom find out?"
"Yes, but that is not the weird part," I answered.
Instantly near hyperventilating, her face went snow white, as she repeated, "Oh my God, oh my God, oh my God."
"That's what she said," I joked.
"This is not funny, Anthony," she said, in extreme panic mode.
"We have nothing to worry about," I said, putting my hand on her leg.
"Don't you dare start with me. You are to blame for this," she snapped, slapping my hand away.
"You didn't seem too concerned while I was you were coming on my face or when you begged me to fuck you," I smirked, having fun with my high-strung sister. Although if I didn't know what I knew, I am sure I would be freaking out just like she was.
"Stop it Anthony, this is serious," she said, tears beginning to flow.
"Ok, ok, I'm sorry, but let me explain," I said, realizing I had to tell her the truth. "But you can't freak out."
"It's a little too late for that," Lilly said, surveying the area for mom.
"Mom is ok with it," I said.
"What?" Lilly asked flabbergasted by my seemingly absurd statement.
"Actually she is more than ok with it," I added.
"What the hell are you talking about?" she asked frustrated by my vagueness.
"Mom..." I began, but was interrupted.
"Mom what?" came a voice from behind us.
Lilly who had just begun to regain some color in her face again went ghost white.
"I was just beginning to tell Lilly about our discussion Mom," I answered.
"I don't recall our conversation being a tell all," Mom replied, putting her hands on Lilly's shoulders.
Lilly froze in place like a statute completely overwhelmed by the situation. Finally, Lilly spoke, "I'm so sorry Mom."
"Sorry about what?" dad's voice asked out of the blue.
It was my turn to replicate Lilly's white face.
Mom tried to cover for her children whose faces had guilt written all over them saying, "Oh Jack, she was just telling me she wasn't feeling well and may have to call it a night."
"Oh, that's ok honey," Dad said, "all that is left is cutting cake and watching relatives get drunk."
Mom laughed, her response dripping with innuendo, "Yes, all the interesting things to see have already happened."
