I arrived at Lucy's house parked the car and rang the doorbell, I had called her on the way to say that I needed to stay with her for a while. Lucy was one of my flatmates at uni, we dated briefly in first year, but both decided a formal relationship was a bad idea as I struggled to keep it in my pants and she struggled to keep it out of her panties. Everytime we fucked up we'd always turn to the other for support though, and everyone who knew us told us to just grow up and get together, but we were certain that was a bad idea.
The door opened and Lucy was stood there in a pair of cut-off jeans that showed off her long legs and a tight cami top that showed off her slender frame, with her long black hair she was very conventionally beautiful and could easily have been a model. "Hi babes, good to see you." She said, leaning in for a kiss on the lips.
"Hello sexy, how's your summer been so far?" I asked as she ushered me inside and into the kitchen.
"Good thanks, just chilled out, yours?" She replied.
"Uh, yeah, similar..." I responded cagily.
"C'mon babes, you really think you can fob me off like that?"
"No, sorry, I just don't want to talk about it right now."
"You know I'll get it out of you anyway don't you?"
"Yeah..." Lucy could be very persuasive when she wanted to be, but I wanted time to come up with a convincing lie, I didn't really fancy explaining the truth.
"Based on how early it is I assume you've not eaten, do you fancy some food?" She asked.
"Yes please, thanks babe."
"Ooooh, first sexy, now babe - I am in favour today!" She prodded, "Bacon sarnie OK?"
"Great thanks."
"So how was Hannah? Last I saw she was sucking you like a pro." Lucy asked as she set to work on my bacon sandwich.
"Fantastic, total freak between the sheets." I told her.
"Thought she would be, and did it lead to dumping as hoped?"
"Yep, very next day!" I said with a grin.
We continued chatting as Lucy made and served our bacon sandwiches, she had finally found herself a post uni job through some of her Dad's contacts, working for a company based just down the road from me, so I invited her to share my new flat, an offer she quickly accepted.
"Right, come on then, you're not sitting around here moping all day - let's go buy stuff for our flat!" She said after we'd finished our bacon sarnies.
"If you want." I replied unenthusiastically.
"I do, now come on, you're driving!" She told me as she skipped out of the kitchen.
We had a good time shopping, and I even forgot about what had happened with my sister for a while as we bought the furniture and electricals that would adorn our flat. Lucy was her normal hyper self, the best moment coming in the furniture shop when she found a bed she thought she liked and I suggested she tried it out, to which she responded by lying on her back in the middle of the bed, grabbing her ankles to lift her legs above her head and moaning as if she was having an orgasm, much to the shock and amusement of our fellow shoppers and the staff.
"Yep, this one will definitely work!" She said with a grin after she had 'cum'.
Finally we went clothes shopping, which meant I got treated to my regular Lucy fashion show, as she paraded her chosen outfits for my approval - this girl was indeed magic.
After a quick coffee we headed back to hers, said a quick hello to her parents and went straight up to her room as she shut the door behind us.
"Now then babes, you are going to spill... what have you done this time?" She asked, gently pushing me so I sat down on the sofa.
"I'd still rather not talk about it..." I told her.
"Well I'm afraid I'm not giving you a choice..." She told me, slipping off her cami top & cut-off jeans to reveal no underwear and her amazingly tight body.
"Fuck..." Seeing her naked body always got me instantly hard, an effect I know was pretty widespread, "Please don't do this..." I knew what was coming, and I'd much rather put my lie through a much less difficult test.
"You've left me no option babes, turning up at my house with little notice and nothing other than what you're wearing means you left somewhere quickly and I want to know where & why!" She told me as she undid my belt, unbuttoned and unzipped my jeans. I instinctively co-operated as she pulled my jeans and boxers down, my hard cock springing free into her face, as with one movement she took the entire length into her mouth.
"Oh fuck!" I moaned, Lucy gave the most amazing head and had used this technique to get things out of me before, the first time being when I had cheated on her during our brief original dating.
Despite having cum inside my sister that morning she quickly brought me to the brink of orgasm, before letting my cock drop from her mouth, "Now you know this is where you're staying until you tell me don't you!" She said, a twinkle in her eye, before diving back down and wrapping her lips around my cock.
Lucy was an expert at keeping you on the point of orgasm, the longest I'd previously resisted this torture was just under half an hour. She gently licked and sucked my cock, being careful to do nothing that would make me cum as I moaned. Then, ten minutes in, my phone rang. Without stopping she fumbled in my jeans pocket for it and pulled it out.
"It's your sister; do you want to get it?" She asked.
"Nah, it's OK..." I said, trying to stay calm, as Lucy put the phone down and continued her assault on my cock.
The phone rang off, but a minute or so later a text came through, given my position I could hardly tell her not to read it, I just hoped it wasn't incriminating...
"She's just text you." Lucy said, breaking off from her sucking for a moment, "Says 'Please call me bro, we need to talk x'. Maybe you should call her, it sounds urgent..."
"Uh, yeah, I will later." I said, trying to hide my obvious guilt.
"Oh my god, you didn't did you?" Lucy asked, a big grin suddenly spreading across her face.
"Didn't what?" I asked, trying to stay calm.
"You dirty bastard you did didn't you!" She said, grinning, her hand still gently stroking my cock. "You fucked your little sister!"
"How..."
"I can taste pussy on your cock babes, and your guilty face when I suggested you called her means 2 + 2 = incest!" She said, before diving back down onto my cock.
"Oh fuck..." I moaned as Lucy increased her assault on my cock, she was obviously happy she'd got her answer. "But you're not disgusted? Oh fuuck, mmmmmmm." I asked, before cumming in her mouth.
Lucy swallowed my cum in one gulp, showing me her clean tongue "Disgusted, no; intrigued, yes! I saw her at Christmas remember; I could tell she was a slut, and a fit one to boot!"
"How could you tell?" I asked.
"Takes one to know one, now I want all the gory details babes!" She told me as she lay back on her bed, her fingers sliding down her body to her pussy in anticipation.
I sat and watched as Lucy brought herself to orgasm twice as I recounted the debauched story of my summer with my sister, I left no details out and it was a pleasure to watch her beautiful body writhe in orgasm infront of me. When she had finished and regained her breath she sat up and took my hand and looked me in the eye:
"Babes, you need to stop beating yourself up. She was obviously gagging for you, and incest aside you've done nothing wrong."
"You think?"
"Yeah, the poor slut was obviously gagging for a cock inside her. If I didn't get any for a month I'd probably be trying to get the dog to fuck me or something!"
"Thanks Lucy, that's a weight off." I told her.
"Good, but you need to call your sister!"
"I need to think about what I'm going to say - can I do it tomorrow please?"
"Do you promise?" She asked.
"Yes Miss. Lucy..." I replied with a grin.
"Watch it you, now let's go get some food & hit the hay."
We both got dressed and went back downstairs, made ourselves some tea and went to bed.

***************************
I woke up for the second time in a couple of days to find a pair of lips around my cock, this time however they were Lucy's.
"I'm horny babes, fuck me?" She asked, seeing I was awake.
"With pleasure!" I grinned, as I watched this beautiful woman mount me.
"Ooooooh, I love the feel of your cock sinking into me!" She said, as her pussy slowly slid down the length of my shaft until it was all inside her.
Lucy rode me slowly as I played with her nips and clit, knowing exactly which buttons to press and when to give her maximum pleasure. Then, my phone went; Lucy grabbed it before I could stop her.
"It's your sister, I'm answering it!" She told me in no uncertain terms, my cock still buried in her pussy. "Shhhh!" She gestured as she pressed the speaker phone button.
"Hello?" I heard my sister's voice.
