Emma loved to tease older men. Her best friend had introduced her to adult chatrooms a few years ago, and she loved to go on and make older guys really hot and bothered. She also fantasised about being put in her place by someone more experienced, but to the outside world you couldn't meet a more innocent girl. At twenty, a few of her boyfriends had tried it on with her but she restricted them to heavy petting. Online she could be as naughty and wild as she liked, and nobody would ever know. After all, she felt fairly safe that these random strangers were probably a million miles away from her real life and even if they weren't, she didn't give too much personal information about herself away. She could therefore explore her hidden, deviant kinks in secret, and she loved it.

I too never expected to ever encounter anyone I knew online. It was just entertainment to explore sexual fantasies. Unlike Emma, I had acted on a few of mine, but nowhere like what I spoke about in the chatrooms or in stories. Still, as I chatted to Emma online, I couldn't help but think of my twenty-year-old daughter's best friend. I didn't think it likely, but once I got that idea into my head I couldn't stop imagining that it was my daughter's friend who was describing sucking my cock, or fucking me, or letting me pump gallons of cum into her ass. I had never thought about my daughter's friends like this before, and part of me was bothered that I was. Still, it didn't stop me picturing the real Emma on her knees in front of me in the coming weeks. Finally, I couldn't stand it any longer and I had to know.

Late one night, I was talking with my beautiful daughter Lacey and stroking her hair and I decided to just ask her.

"Do you know if Emma ever goes on to an adult chat room site called Lush Stories?" I inquired.

Lacey took her mouth off my cock and looked up at me... oh did I mention I was sleeping with my daughter, or in fact my stepdaughter in truth? I know I shouldn't, but when she came to me after she became legally an adult to talk about her sexual dreams, I couldn't help myself. I probably shouldn't have patted the bed and invited her to sit down next to me with a raging hard on, but it had been so long since her mother died, and she was such an attractive eighteen-year-old. I probably should have stopped her when she grabbed hold of my cock and started stroking it as she spoke her erotic fantasies to me, but what can I say? I'm a weak, horny man. Some people would say that it wasn't appropriate for us to resolve my son (her stepbrother) Mike catching us together a few months later by getting him to join in, but the sex was amazing. But that is maybe a story for another time. Sorry for getting distracted, back to Emma...

I could hardly believe it when Lacey said that she had introduced Emma to Lush and that both of them were often on the site in question. We had never crossed paths, but I thought it would be a great joke if we started chatting there. We could even have her call me "daddy" online, and nobody would ever be any the wiser. I asked Lacey if she would mind if I seduced Emma, and she jumped up in glee. I think the two of them had fooled around a bit, but Lacey wanted to have her almost just as much as I did but had never built up the nerve to act on it. As we rode each other to climax, we made a plan for Emma's seduction.

It was a Saturday evening when Emma came over to see Lacey, but I had agreed that Lacey would actually go out with her brother. I think Emma was a bit confused that Lacey was not there, but I invited her into the lounge and put my plan into action.

"I gather you have been a naughty girl, Emma?" I said looking at her sternly.

Emma turned a glorious crimson as I held her gaze. "I don't know what you mean Mr Deane," she finally stammered.

"My daughter tells me you have been frequenting adult websites and chat rooms," I informed her.

Emma sat for a while in shock, trying to digest that her friend had given away her secret.

"What's more, I think we have spoken, and you revealed yourself to be a horny slut," I added, as Emma struggled to formulate a response. I pressed my advantage home as she sat stunned before me.

"I don't think this is very appropriate behaviour for a church minister's daughter, do you?" I questioned. I don't think she even stopped to think that it would also not look great on me if I gave away that I had been on the site as well. Instead, I watched as she went slightly panicky thinking how bad this could get for her.

"Please don't say anything Mr Deane!" she cried out, re-finding her voice.

"You can start by calling me 'Sir'" I replied in glee.

"Please, sir, I'll do anything," she added.

"Well, I suppose I could punish you myself," I said stroking my chin as I pretended to consider this. "OK, get over here and bend over my knees," I instructed her.

Slowly but surely, Emma got up and approached me. I pulled her to me and bent her over my lap, hitching up her skirt. My hands slid over her delectable ass before I yanked her pants down leaving her exposed before me. I drew my hand back and spanked her gently.

"What are you, Emma?" I asked. She looked up blankly at me. "You're a dirty little slut, who deserves to be punished," I told her. "Say it!" I urged her as she bowed her head in shame.

"I'm a dirty little slut who deserves to be punished," she moaned as my hand fell again.

"Louder!" I told her as I spanked her again.

"I'm a dirty little slut who deserves to be punished!" she said more forcefully.

After about six or seven slaps (I think I lost count!), her ass was warm and red and she was practically shouting the sentence for me. I rested my hand on her ass and allowed my other hand to stray down to her sex. She was dripping with juices.

"See how wet you are," I said to Emma as I took my fingers up to Emma's mouth and fed them to her. She instinctively started sucking her own juice off my fingers.

I had her stand up and found a music track on my phone.

"Strip for me," I ordered her.

I could tell Emma was still somewhat embarrassed as she started swaying to the beat and running her hands over her body, but gradually she got more confident. She was a good dancer, and I loved to watch her dance for me.

"Good slut!" I encouraged her as her movements became more sensual.

Emma peeled off her top to leave her standing in a lacy black bra. God, her tits are fantastic, and I couldn't wait to get my hands on them. Next came her skirt so she stood naked before me. Her ass was still red from our earlier activities, and I had her twirl around and show herself fully to me.

I pulled Emma to me once again and encouraged her to her knees.

"Your slutty behaviour has made me get somewhat uncomfortable," I said, guiding her hand to rest on my crotch. "Take care of it for me," I told her.

Emma gasped at the feel of my stiff member and shook her head.

"What do you say to me, slut?" I hissed as she hesitated.

"Yes, sir," she finally responded as she peeled down my zip and lowered my trousers. Painfully slowly, she leant forward and planted a kiss on the tip of my cock beneath my boxers. Emboldened, she reached forward and began stroking it beneath the cloth. My cock throbbed uncomfortably as a small wet spot became visible on my boxers.

Growing impatient, I yanked my boxers off and my cock sprang free practically hitting her in the face.

"Now open up and suck," I told her as she stared at it. I wasn't sure how many dicks she had seen, but I knew that, whilst I wasn't porn star massive, I was big enough. Emma definitely seemed to be drooling as she sat on her knees in front of me.

I wasn't to know as she leaned forward that mine was the first prick she had ever sucked, but as she lowered her head onto my stiff member, I couldn't help but close my eyes and sigh. Emma started to lick my mushroom head, before sliding more of my hard shaft into her mouth. She raised herself off me, then licked down the underside of my swollen knob, before taking one of my balls into her mouth. After doing this for a while, she kissed up my length again before opening her mouth and taking more of my stiffness between her lips even deeper than before. I grabbed hold of her long blonde hair and encouraged her to keep going. I sensed her tense up as I hit the entrance to her throat.

"Good slut," I encouraged her. "Keep going."

I applied a bit more pressure to her head and felt my cock slide into her throat. The sensations as she squirmed beneath me were intense as I held her there for a few seconds before letting her pull up and gasp for air.

"You're doing so well, Emma," I smiled as she looked up at me with wide eyes. "You had nearly all of me in your mouth there. Wouldn't you like to please me by fitting all of my cock inside your lovely mouth?"

"Yes, sir," she replied as she began to take me back between her lips.

"Just relax," I urged her as she took me deeper.

It took a few attempts, but in no time I sat in wonder as she took me balls deep into her mouth and began to bob frantically back and forth. Her hand had strayed to her sex as she rubbed her sweet pussy whilst deep throating my dick. Eventually, I reached the point of no return as I spewed a load of hot cum into her mouth. Emma didn't miss a beat as she swallowed my sticky load, lost in her own orgasm.

I picked Emma up and kissed her for the first time fully on the lips. I know some guys don't like the taste of their own cum, but I love it, especially when it comes from the mouth of a gorgeous twenty-year-old.

I picked Emma up and carried her to my room. I lowered her onto my bed, naked as the day she was born, and began to strap her arms and legs to the corners of the bed with fastenings Lacey and I had arranged earlier.

I don't think Emma was aware of anything that was happening at first as she lay there, but she came back to herself with a start.

"What are you doing, Mr Deane?" she cried out as I fastened one of her ankles to the bottom of the bed.

I cupped her face in my hand lovingly.

"It is 'Sir' remember?" I said. "Don't ask questions."

Emma lay in stunned silence as I finished my work and stood back to admire her. God she was beautiful.

I lay down beside Emma and stroked her face and kissed her neck. Slowly, with deliberate movements, I allowed my hands to stroke down her body to her heaving bosom. Emma whimpered as I began to squeeze her breast and gently nip one of her hard nipples.

I lowered my head to take her other teat between my teeth and gently nibble. As I sucked more of her breast into my mouth, my hands wandered lower as I felt for her wet sex. I felt the top of her pussy and stroked her nether lips as she let out a deeper moan before me. I wet two fingers and slid them inside her moist hole and began to pump them in and out of her.

My cock was fully hard now, and I couldn't wait any longer to feel myself inside her. I moved myself so that my dick was touching her moist folds.

"Do you want me to fuck you, my pet?" I asked her.

"Yes, sir," she simply nodded with a moan.

"Yes, sir what?" I teased her.

"Yes sir, please fuck me," she responded in growing need.

"You can do better than that," I told her as I hovered at her entrance.

"Yes sir, fill my pussy with your stiff cock and make me yours," she screamed as I began to slide into her fuck canal.

With a sudden push, I slammed into the beautiful creature below me.

"Were you a virgin, Emma?" I asked in shock as I felt myself burst through her hymen. I had always assumed that she had been sleeping with her boyfriends and would never have taken her so roughly if I knew. Emma just whimpered beneath me, I wasn’t sure if it was from pain or pleasure. I think it was a mix of both as she moaned again.

"Do you want to stop?" I asked, feeling a bit ashamed of how I had treated her.

"No, fuck me!" She cried out as she started to thrust herself up towards me.

I responded to her, and soon I was slamming into her wonderful tight young pussy.

"Yes!" she uttered as I began to move back out almost to the tip of her entrance and then back in fully to her welcoming sex.

"Harder, please sir, make me cum!" Emma squealed as I began to pump her wonderful cunt with my throbbing meat even harder.

I grabbed hold of one of her tits and squeezed hard as I felt my own orgasm approaching.

"Cum for me, Emma!" I ordered her as I felt my own cum boiling up once more.

She screamed and I felt her pussy muscles clamping onto my shaft as I erupted into her. I wasn't sure if Emma was on birth control, but we could cross that bridge if we needed to. Somewhere in the back of my mind I wondered if Lacey would like another brother or sister, but there were lots of other options.

Emma and I lay on the bed for a while before I went to get up to get a drink.

"Aren't you going to release me?" Emma said with nervousness as she watched me go.

"Soon," I promised her as I left the room and rang Lacey.

I don't think Emma could quite believe it when I returned with Lacey behind me. If she had her arms free, she would have covered herself, but as it was she just looked on in extreme embarrassment as Lacey walked in the room.

"Have you been fucking my daddy, Emma?" Lacey asked her with a glint in her eye.

Emma moved her mouth but nothing came out.

"I can't blame you really, he has such a nice cock," said Lacey as she grabbed hold of me and sank to her knees.

Emma could only stare at her best friend as she began to take my own cock deep into her mouth. Emma thought Lacey told her everything, but she had never imagined that Lacey and I were involved together. We knew it was a risk revealing this now, but we felt sure we could keep our secret. Especially as Emma now had secrets of her own.

Lacey stopped her glorious blow job and grinned at her friend still laid out on the bed.

"Not that I can blame you either, Daddy," said Lacey. "She does look yummy."

With that, Lacey lay down and started kissing Emma on the mouth. Emma felt overwhelmed but opened up on instinct and began passionately kissing Lacey back. Lacey grabbed hold of one of Emma's boobs before moving down to suck it, much like I had done before. Slowly, she kissed downwards until she was lapping at Emma's sweet pussy. She knew that I had cum there recently, but this just increased her vigour as she lapped at her friend's sex.

Emma looked up at me with a gleam in her eye.

"Can we keep her Daddy, please, can we?" asked Lacey. Lacey had told me that Emma wanted to move out of her family home, but the idea of her joining ours hadn't been on my radar.

"I suppose so," I said finally. "It's been a while since I got you a new toy."

"Well, that's not strictly true..." grinned Lacey as she went to our toy box and got out a new strap-on dildo we had purchased.

As Emma watched, Lacey fitted the strap on to herself and rubbed on some generous lube.

She released her friend from her restraints as she laid down beside her.

"My daddy can be quite demanding at times, but he's a good guy really," whispered Lacey loud enough for me to hear. "Say the word and all this stops."

Emma responded by pulling Lacey's head to herself and kissing her deeply.

"Don't stop!" she whispered as Lacey hovered over her.

Lacey pushed the dildo deep into Emma's well used pussy and began to saw back and forth. She looked up at me with a grin.

"I think we have a new member of the family," she said joyfully as she fucked in and out of her friend. "Imagine all the fun we are going to have," she added as Mike walked into room.

I sat back and just watched as Mike stripped and got behind his stepsister. She stayed still, buried deep inside Emma, as Mike began to push his hard cock into his sister's ass. I was happy to be a spectator as the three of them began to move together, Lacey fucking into Emma's pussy as Mike savoured his sisters back passage.

"Have you taken Emma's anal cherry yet, daddy?" she asked me with a grin.

Emma just moaned as Lacey...
