What a Good Neighbor Ch. 01

"That's a good girl, MY good girl. Mandy look at how she's really taking your finger fucking. You've done very well; she's almost ready for the real thing. Come here, I have something for you."

Mandy immediately turned to me, where I grabbed her and thrust my tongue deep into her mouth. As I did, I reached back and placed a finger between her ass cheeks, sliding down to her quivering puckered star and slipped it into her ass. Mandy hissed into my mouth but also pushed back on my finger only to feel a second finger joining in, then a third. Mandy was moaning and was losing control. Mandy panted and pouted as our kiss parted and even more so as my fingers left her quivering ass.

"OK Mandy, here's the deal for now. Your virgin ass is next. So while I deflower Sandy's ass, you should get your own ass ready. Hold out your fingers so I can lube them up for you. That's it. Now you're ready. Don't you think your ass would enjoy these slick fingers while I take your sister's ass? There you go my little ass-whore to be. Now mimic your sister's thrusts as best you can. That's it; work those fingers in just like you did Sandy -- my twin ass-whores."

I watched as Mandy began to slowly work her ass as she brazenly stared at her sister's gaping ass. Inch by inch she had first two, then three and was now trying to work the fourth finger into her ass. I couldn't help but smile as Mandy began to mimic her twin sister's thrust. Mandy was squirming against her own invading fingers and apparently enjoying every inch of them.

"OK Sandy, your turn. Are you ready to become an ass-whore -- MY ass-whore? Ready to lose that anal cherry to me?"

"OH DAMN YES. I'm so hot I feel like I'm going to explode. Fill my ass with your huge cock. Take my anal cherry. Make me your ass-whore. Anything you want, just fuck my ass. Fuck me hard and deep. Fill me with you hot cum. I'm yours Doc. Please take me now. Take my ass."

Slowly, I positioned myself behind Sandy's glorious ass. After applying another coat of lube to my cock, I placed the head of my cock between Sandy's ass cheeks just below the gapped opening of her ass.

"See this Mandy? See how your sister's ass is really gaped open for me? Your ass will soon be just as open and just as ready. I guess there's no need in asking Sandy if she's ready. OK Mandy, watch this, your sister is about to lose her anal cherry. Mandy, take your free hand, grab my cell phone off the end table and give it to me. We need to save this for later as well."

Slowly, I inched forward until the head of my cock was resting on the gaped opening of Sandy's ass. Holding the cell phone camera in one hand, at first I just teased my cock around the edges of Sandy's gaped ass as I took a picture or two. Then I began a slow tease by just barely slipping the tip in, only to pull it out -- again taking a few photos. Sandy was becoming extremely anxious. She wanted this in a big way. She reached back, grabbed my slick cock and positioned it at her gaped open ass. Then Sandy truly surprised me - in one deep backward thrust she took half my length into her ass with a very audible gasp.

Just as she began the backward thrust, I took several pictures of Sandy's ass swallowing my cock. Her body froze all movement as Sandy realized her lust had caused her to take my cock in that deep. With deep breaths, Sandy slowly began to accept the length and width of my cock. Her inner muscles were rippling around my cock. With another gasp and one final push backward, Sandy had my entire cock in her ass.

"OH MY GOD! OH MY GOD! OH MY GOD! I've got all his huge cock in my ass. I can feel his balls against my pussy and clit! OH MY GOD! I've never felt so full. Oh please, go slow, let me get used to this. I never knew I would feel so full. You were right, your cock is much bigger than Mandy's fingers. But damn, it feels so wonderful. I've never experienced sensations like this. OH yeah, that's it. Rock into me. OH Damn -- I'm going to cum. OH OH OH OHHHHHHHHH AHHHHHHHHHHHHHH YES FUCK ME! TAKE MY ASS DAMN YOU! FUCK MY ASS! Oh God, Mandy, he did it, he took my anal cherry. Oh damn I'm cuming again! AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH!!!!!

I set the cell phone camera down, grabbed Sandy's hips and slowly pulled all the way out only to slam back into her in one thrust. Over and over, I did the same thing. Each time, it just pushed Sandy to a new high. Each time I withdrew my cock, I could only marvel at the widening gape. Slowly I switched to a different tempo of hard half strokes so I could feel my swollen balls slapping against Sandy's wet pussy and clit.

"OH Damn yes, Doc. Fuck my ass. Pound your new ass-whore. Hear that sis, I'm Doc's new ass-whore and he's fucking my ass hard and deep. Are you watching sis. My ass is no longer virgin territory. Now I want your cum, Doc. Fill me. Make me yours. Claim my ass. Take my ass DADDY! DO ME DADDY! FUCK ME DADDY!"

"Damn Sis, this is so damn HOT! His cock is pounding your ass. I can see his swollen balls slapping against your wet pussy. Oh damn, I'm going to cum too, Sis. Why did you get to go first? Oh oh oh. I'm cuuuuummmming toooooooo! YESSSSS FUCK HER ASS DADDDDDDYYYYYYY!"

Sandy and Mandy calling me Daddy mentally pushed me over the edge. I started slamming harder. I wanted to fill her up and I had very special plans for that cum. I could tell Sandy was close again. So with one hand grasping her hip, I slid the other around to seek out her clit. Damn it was almost the size of a peanut now. My fingers started to manipulate Sandy's clit in tempo to my anal thrusts. All Sandy could do was yelp out in a semi coherent state.

"Oh yes, oh yes, oh yes, Daddy. Do me Daddy. uhh huh uhh huh, take it take it take it - take my ass Daddy uhh huh uhh huh right there ohhhh ohhhhh ohhhhhhh OHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH YESSSSSSSSSSSSSS!"

As Sandy came, I moved into overdrive. Her ass was all mine now. Harder and harder I pummeled her ass, feeling my balls slap against Sandy's frothy pussy. I turned my head momentarily to see Mandy grunting and groaning as she was driving her fingers deeper and deeper into her own ass, matching my thrusts into Sandy. As if on queue, the twins erupted in simultaneous mind blowing orgasms. Their mutual screams seemed to drive the other on to a new plateau. I was determined that Sandy would not be able to sit for a long time. As my thrusts became more animalistic, I could feel that all too familiar knot in the small of my back begin to build. Then like a bottle rocket, those electric sparks began to shoot up my spine. As my balls tensed, I began to shoot volley after volley of hot creamy cum into Sandy's ass.

"YESSSSSS FILL ME DADDY! Mandy, he's filing my ass with cum. Damn he's filling me up. I can feel it -- it's so hot splashing into me. Oh yes YESSSSS FILL ME DADDY!"

With each volley of cum I drove deeper and deeper into Sandy's ass. I wanted it deep for a reason. A reason both Sandy, and in particular Mandy, were soon to find out. As my orgasm began to subside, I pushed forward one last time and left my cock deep in Sandy's ass. She reached back to cup my pussy juice covered balls and to feel where my cock was imbedded in her ass. As she traced the length to where it was buried in her ass, she gave another shudder and had a mini-orgasm. I remained in to the hilt and began to feel my cock slowly lose its hardness. As my cock softened, I stroked Sandy's back and her ass cheeks. Knowing it was almost time, I nudged Mandy to drag her back down to earth.

"Mandy, get over here. Do you remember your rules? Didn't you swear you accepted them and would abide by them at all times, just as your sister did?"

"Yes, I did and I will. I promise."

"Such a good cum-slut to be. Now what are you supposed to do if I offer you my cock or my cum?

"I'm to accept it without hesitation."

"That's right. Now get over here next to me as I have something for you."

Mandy scooted over to me, slowing the fingers she was driving into her ass. As soon as she was in position, with one hand I grabbed her by the neck and hair and held her head firmly. By twisting her head slightly, I angled her gaze to watch my cock slowly leave her sister's just fucked ass. As soon as my cock was free, it was if a damn burst. I grabbed the camera phone again and began snapping photos. Cum began oozing in heavy amounts out of Sandy's ass. It was running all over her pussy lips and over her clit. Once Sandy's pussy and clit were coated enough to suit me, I gently pushed Mandy's head to the sweet spot. Pausing there, I took another couple of photos.

"OK Mandy, I am offering you my cum, now lick it all up like a good cum-slut. You still want to be my ass-whore and cum-slut don't you. Sandy, reach your hands back and spread your cheeks for your sister. Mandy's also going to tongue my cum from your ass until you are completely clean."

Mandy leaned forward tentatively at first, and then hesitated. So I leaned over and whispered into her ear.

"Come on Mandy, show your sister that you're going to be a better cum-slut than she is. I know you can do it and I'll be really proud of you. See if you can make her cum for you by licking my cum off her clit and pussy lips. I bet you can. Just lick her pussy and clit like you want her to lick you when it's your turn. Now do it for me, take my cum, lick it all off and make Sandy cum again for me, for US!"

That was all the extra encouragement Mandy needed. Her tongue snaked out and began to lathe over Sandy's cum covered pussy lips. As her tongue worked up and down her sister, I took a few more close-up photos of her tongue licking up my cum from her sister's pussy and clit. Sandy began to moan at the onslaught. Just as I had hoped, when Mandy zeroed in her tongue on Sandy's cum covered clit, Sandy had another major orgasm. And just as I had hoped, in doing so, it caused her inner muscles to contract and there was a fountain of cum flowing from Sandy's ass.

"Good girl Mandy. I knew you could do it. Now look at all that cum. It's like her ass is a cum water fountain just for you --- and your sister. Remember, you are to share what is given to you. Lap my cum from her, but don't swallow -- at least not yet. That's it, run your tongue deep into her gaped no longer virgin ass. Get it all. Use your fingers on her clit and make her cum again. Let's make sure you get it all out. That's it, Sandy likes her sister licking my cum from her ass and her sister playing with her clit. Just like Sandy will do to you later today. That's it, she's cumming again. Get your mouth over her ass and catch that cum. Good girl. I think you've got it all. Now, share it with your sister and BOTH of you swallow it all my little cum-sluts."

As they kissed, I guided Sandy's hands back to join the fingers buried deep in Mandy's ass. Then I whispered to Sandy, then to Mandy.

"That's it baby, start getting her ready to loose her anal cherry. Now both of you, swallow all you have because you have some cock sucking to learn. You two are going to suck my cock until I'm hard, so I can take Mandy's anal cherry. You're both going to be my ass-whores and cum-sluts before you head home later."

I watched with pride as the twins swapped my cum. Their kisses were hot and passionate. As they kissed, I slowly placed my hand atop Sandy's hand as she worked her fingers into Mandy's ass. Sandy needed no encouragement at all as she immediately started to work her fingers in and out of Mandy's ass with more enthusiasm. Watching the two caused my cock start to rise slightly. Yes, I wanted Mandy's ass, but I was going to need the girls' help getting my cock ready for round two.

Basic math told me "52 into 19 times two" doesn't work too well without some help. At that thought I smiled and gazed at the two 19-year-old twins before me. They were lost in a sea of lust.

"Wait a minute here! Did Sandy and Mandy really call me Daddy while I was taking Sandy's ass?"

Chapter 3

It's A "Two Fer" Afternoon

I slowly sat back contemplating the events of the afternoon thus far. Not only am I now out of my hermit like doldrums and celibate life, but I have two naked 19-year-old vixens writhing in front of me swapping my cum. DAMN! I couldn't believe the abrupt change in my life. Now it was time for round two -- after a little help from my new found friends.

"Goodness girls, you two seem to enjoy my cum. Don't worry, there's plenty more for the two of you -- LOTS MORE! But, we need to talk a bit before we continue. When you two are quite through, come over here and sit on the floor in front of me."

Mandy and Sandy slowly loosened their arms from around one another. Breaking their lingering kiss, they both licked their lips as they turned to me. Like proper little cum-sluts, they obeyed my wishes and sat in front of me. However, as Mandy sat back on her heels, her eyes bugged out and a smile crept across her face. I then noticed Sandy had sat similarly beside her and Sandy's hand had slipped behind Mandy. Upon closer inspection I could see Sandy's fingers sliding in and out of Mandy's ass.

"It seems Sandy has overcome her previous reluctance to play with your ass, Mandy."

Mandy smiled and nodded as Sandy blushed. But, Sandy continued with a renewed vigor. I sat back on the loveseat and allowed my legs to spread apart. The two girls began to stare at my semi erect cock. It still had a sheen from the ass fucking I had just given Sandy. In addition, there was a rather large dollop of cum still weeping from the tip.

"You two missed some of my cum. I see you both looking, but now is the time the two of you should be licking. Both of you, NOW! Lick, kiss and suck my cock. It's your cock now, so worship it like good cum-sluts."

Both girls looked at one another as if mentally asking what to do next.

"But your cock was just in my ....."

Sandy never completed her sentence. Mandy leaned forward sliding out her tongue and began to lap at the head of my cock. Once she retrieved the last dollop of cum, her eyes cut up to mine. I just nodded to her sister. Mandy leaned in and kissed Sandy to share the last of my cum. In short order, they were swapping the last of my cum between their tongues. Mandy was finally the one to break their kiss and turn toward me.

"That was the hottest thing I have ever seen. I never once thought my sis would be able to take all your cock in her ass. And when Sandy came all over my mouth when I was licking your cum from her, I could almost feel her orgasm inside me. But, when you had me share your cum with her, it just sent me over the top. My pussy is so wet and Sandy has my ass begging to be taken."

"Sandy, why did you hesitate to take the cum from my cock that was offered to you? Yes, my cock had been in your ass, but you had just moments before readily accepted my cum that came out of your ass when your sister kissed you. That's a bit hypocritical on your part don't you think?"

"Yes, Sir, Dad ... I mean Doc. Now that you put it that way, I just didn't know what to think."

"Well, you and I will work on that for sure. Remember your rules -- any time I offer you my cock or my cum -- you are to accept it WITHOUT hesitation. Which brings me to my next observation ... you both called me Daddy there toward the end. What was that all about? Enlighten me."

Both girls blushed and their heads hung for a minute. Mandy nudged Sandy as if imploring her to tell me. Sandy just looked at her sister then looked at me. She started to speak, but her mouth just moved, no words coming forth. I couldn't help but grin and try to keep from laughing aloud. Sandy finally smiled and looked up at me.

"We both have fantasized about you being our sexy Daddy and teaching us how to be naughty daughters for you. We've played with one another at night in our bedroom making up fantasies about you being our sexy Daddy and would cum like crazy. We both kind of let that part slip as we were both so turned on. If it bothers you, we'll try not to do that again."

"Ladies, it is completely OK with me. In fact, I kind of like the idea of being your sexy, NASTY Daddy and teaching his nasty daughters to be his little cum-sluts. Do you want me to be your NASTY sexy Daddy?"

Sandy and Mandy looked at each other as their smiles grew wider and wider. Almost in unison they both screamed out.

"Oh Yes, Daddy!"

"OK, that's settled then. Both of you lean over here, kiss and suck your nasty Daddy's cock. You first Sandy. NOW!"

Sandy's eyes looked up at me and grew wider. As she leaned forward her lips pursed. At first she just stared at the cock that had just taken her ass. It was her first true up close look. Sandy licked her lips and leaned in closer still. She wrapped her tiny hand as best she could around the still glistening semi-erect shaft and then kissed the tip. Her tongue then slid forward and she began to lick the head, sliding her tongue all around the corona. Then as if some sort of spell came over her, her lips parted, formed an "O" and she engulfed as much of my cock as she could.

"That's a good girl Sandy. Be Daddy's nasty little cum-slut. Suck Daddy's cock. Suck the cock that just took your virgin ass. Make it hard so it can take your sister's ass. Now Mandy, you need to be Daddy's nasty cum-slut too. Lean over here and take turns. Sandy, let your sister have some of her Daddy's cock. Make sure you two get it all. Lick from my balls all the way to the tip. Get every inch that was in Sandy's virgin ass. And if you want to be really nasty girls for Daddy, you can take turns sucking Daddy's balls and then licking around Daddy's ass. Daddy likes his ass played with just as much as you two do."

I just sat back and watched. Sandy and Mandy were taking turns licking up and down my shaft. Then they would take turns sucking the head of my cock into their hot little mouths. As one sucked the head, the other would lick down the shaft and suck my balls. With their eager mouths and tongues working in unison, my cock began to grow. As it did, their eyes grew bigger as well.

"Such nasty little girls I have. Look how you're making Daddy's cock get bigger. If you keep this up, Daddy will be ready to take Mandy's ass in no time at all. Such good little girls you are ... MY good little cum-sluts."

The praise seemed to give them more inspiration, or perhaps it was a bit of sibling rivalry. In either case, the two girls worked at seeing who could take more and more of their "Daddy's" cock. I watched and marveled at how well each was doing. Before long both girls could get about half of my cock in the mouths before they began to gag. Not bad for starters.

Then it was Mandy that surprised me. As Sandy was working more of my cock into her mouth, Mandy was licking down my shaft, then over my balls. Then WHAM -- her tongue zeroed in on my ass. At first it was just a few tentative licks. But by the third pass, she began to press her tongue into my ass. She was definitely going to be my natural anal-slut. Needless to say, between their double efforts my cock was once again at its full 10 inches, possibly more.

"Such wanton and hungry girls, you're both so hungry for Daddy's cock. Look how hard you made it. It looks hard enough and big enough to take your sweet ass doesn't it, Mandy?"

Both girls stared at how large my cock had grown. It was all nice and slick now from their saliva, not from the fuck juices and lube from Sandy's ass. The two girls had cleaned all that off and replaced it with their own juices. Sandy looked at my cock, then at Mandy, then back to my cock, then back to Mandy, then back to my cock.

"Did he have ALL THAT up my ass? WOW! I've got to see it take your ass, sis. I mean, WOW! The thought of all that cock going into either of our asses is amazing. It makes me hot all over just thinking about it. And I'm going to get to see it. Go on Daddy; take Mandy's ass like you did mine."
