It's my 18th birthday and I suppose I'm an adult now but I don't want to grow up. I just graduated high school and it's my last summer before I'm thrust into a world of endless responsibility. Can't I just pause this moment and live forever on summer break?

Blinking awake but not ready to face the day, I roll over onto my stomach and press my hard on into the mattress. I always wake up horny and ready to relieve myself. I start to grind into my bed and enjoy the feelings when I hear my door open and my dad steps in.

"Happy birthday bud!" He says a little to peppy for the early morning. He walks over and sits on my bed, making himself right at home. He rubs my back and pats my butt, repeating the motions as his hand rests on my butt longer each time, giving it a playful little shake.

"Thanks daddy, I don't wanna grow up." I look at him and pout. I don't feel like a man, or look very much like one. At 5'4 and 125 lbs I'm still a skinny guy, except for the lower half of my body, my legs are thick and my butt is big.

I didn't play sports in high school, never felt rough and rowdy like a lot of the cooler guys. I game a lot and prefer solo activities so I keep to myself mostly.

"Come on big guy, let's get you up and ready to celebrate." With that he moves my blanket off of me to reveal my undies covered bottom and resumes the butt pats. "What do you want to do today?" He asks me.

It's always just been him and I, mom ran off early on before her and my dad had a chance to have another kid. He never dated, never seemed interested in anything more than a one night stand every so often.

"Anything. Let's eat and watch a movie." I recommend, subconsciously pushing my butt out as my dad keeps rubbing it. His big strong hands always felt good on my body. We've always been really affectionate towards one another, lots of hugs and forehead kisses. It was nice, especially since neither of us got much attention elsewhere.

"Sounds good to me, why don't we grab breakfast and then head to the movies." He shakes my ass with excitement for emphasis.

"Daddy." I giggle, feeling the vibrations from his motions. "Thanks for the birthday massage. I really liked it."

"Anything for you buddy. I can give you a more proper one if you'd like." He straddles the back of my thighs and I feel his bare legs on mine since we're both in our underwear. His hands travel up the small of my back to rub my shoulders and kneads a few times before rubbing back down again. He repeats this process for a couple minutes as I melt into my bed and press my hard dick into the mattress, thankful he can't see it.

The touch of his hands varies from slow, fluttering finger swipes to a deeper kneading that drives me wild. I didn't need any presents for my birthday but this massage is the best gift possible.

As he works my shoulders, he moves up my thighs a bit and I feel him make contact against my butt. I can't tell if he's hard but I can feel the heat from his package touching me. I moan slightly, enjoying his massaging hands.

After a while he asks, "How's that feel buddy?"

I breathe out deeply and respond with a "So good," that mostly came out a moan. "Keep going please."

"I won't stop 'til you ask me to," he replies.

I periodically grind into the mattress and as I lift my butt back up I feel his dick more prevalently now. This time I can feel his hard dick trapped in his underwear. I swear I heard him suck in a breath and stifle a moan as I involuntarily let one out.

"Can you work my lower back a bit?" I ask, hoping he would include my ass well.

"Sure thing." His thumbs focusing on my back dimples, making small circles as the rest of his fingers lightly massage my sides, just above my plump booty.

"You're a little tight here son, you sit too much." He teases me a lot about my sedentary activities but I don't mind it.

"No way, I probably just need more massages." I say jokingly, but truthfully wouldn't mind if they were a daily occurrence.

"That's one option. You might need to up your exercise routine, it looks like you're a little bigger since school let out." He tells me as he pinches my butt.

I stifle a surprised squeal as I retort back "I exercise enough, I get my steps in when I need a snack from the kitchen."

'"I don't think that's gonna cut it buddy. Looks like all the snacks are staying put right here." He lightly smacks my ass as he finishes his sentence.

I have to bite my lip to stifle a moan, his berating was doing nothing to lessen this high. If anything I was loving the attention he was giving my ass.

"It"s normal, no bigger than a handful." I hope he tests to make sure. I was not disappointed as he grabbed a cheek in each hand and shakes my ass. I laugh a little and move my butt in a faux attempt to get his hands off but it just shakes my ass even more. "Daddy..."

"Sorry son, I couldn't help myself, you got a big butt. Kind of inviting.." He says as he finally let's go and resumes the massage. '"I could massage your glutes for you too, if you want. They say they hold a lot of tension."

"Oh sure, if you think that'd help. That would be nice." I say, trying to sound nonchalant even though I was screaming inside.

"Alright.. Well I could get to the muscle better if you take your briefs off." He recommends.

"Oh yeah, that makes sense. I can do that." I start to slip my underwear down, staying close to the bed trying to hide my boner. I was awkwardly sliding them past my thighs and I feel the cold, cool morning air on my butthole as my cheeks spread as I maneuver my underwear down. Just above my knees my dad takes over and I bend my legs so he can take them the rest of the way off.

"There, that's better." He says as he places his hands on the top of my thighs and massages just under my cheeks, framing them and grabbing them from underneath. He moves his hands back up the sides of my butt and caresses my ass. He openly grabs the cheeks now, softly yet firm, manipulating my ass and feeling me up.

"Actually, maybe you don't need exercise, I think all that gaming is doing you just fine." I blush at the comment, clearly dad was admiring my big butt cheeks.

I feel his breath on me as he's speaking, I feel the words tickle my ass. I subtly look back over my shoulder and see his face leaning down, close to my cheeks and he's inhaling me while massaging my ass. His face inching closer and closer to the crack of my ass and each movement of his hands revealing my butthole as my dad looks on intently. I flex my hole a bit, winking at him and he bites his lip. He leans down a bit more as he takes a deep breath in.

I relax my head back down and leave him to it, he was in the zone kneading my ass obsessively and smelling my morning scent. I repeatedly grind into the mattress and then push away from it, moaning slightly. Enjoying the close contact and spontaneous sensual massage. I was so fucking horny, I've never been touched like this before. This was already the best birthday I've ever had.

"This feels so good daddy, I wish I could get a birthday massage everyday." I tell him. He continues palming my soft, pliable cheeks, caressing my skin. My butt felt so good under his touch, his strong hands massaging my hairless ass.

"We just might have to pretend every days your birthday then buddy." Music to my ears. Again I feel his breath on me, closer and more intensely this time. I chance another look back and see him mere inches from me, his eyes closed and his nose almost directly on my hole. I push back a little and make contact with his face, he didn't try to pull away and I didn't push back down.

We stayed that way for a second until I ground my ass into his face a little more. My cheeks then encompass his face as he shakes it deeper into my crevasse. He was fully enveloped in me as his hands reach up my back as far as they can and he brings them back down to squish my cheeks around his head.

I finally feel his tongue flicker out as he makes first contact with my hole. It was like lightning every time he would flick his tongue out to lick me there. Another first, I was moaning loudly now as my dad's thick tongue was soaking my asshole.

"Oohh daddy." I groan as his tongue licks my crack up and down. I've always been a little self conscious about my big booty so it felt so good to be the object of someone's desire. And my dad's fat tongue licking me up was so incredible. "Mm, that feels so good."

"Wow baby, i didn't realize you had such a sweet hole back here. You taste so good." He says between planting kisses on my hole before diving right back in. He lifts up periodically to take in a deep breath of me. I was so horny, I kept grinding my hardness into the mattress.

I've always loved watching guys get rimmed in porn but I've never gotten to experience it personally. Dad's tongue in my ass exceeded all expectations. I was squirming on the bed and clutching the bedsheets. I was leaking precum already, he was driving me crazy.

"Oohh daddy, woow." My voice getting higher as I moan from the sensations. I arch my back and thrash my head back. He grabs my butt cheeks and jiggles them around his face, trying to swallow him up.

Dad licks my taint area which places his nose directly on my hole, breathing in my most private part. He traps his nose there with my cheeks, squeezing them together. I feel the hot air that he exhales land right on my hole, making me shiver. After a bit he lets up and resumes long swipes of his tongue up and down my booty crack.

"Damn baby boy, you've got such a sweet hole. I always noticed your big butt but I had no idea what you were hiding between these cheeks " He says as he gives them a slap and rubs a finger around my tight hole. "Did it feel good when daddy licked you here?" He asks as he applies a little pressure and I feel his finger pop through my defenses.

"Oohh, yes daddy. Your tongue feels amazing. So do your hands on me." I moan in enjoyment. His finger entering me was surprising but not too painful after the initial breech. He starts moving it further inside of me, rocking it back and forth.

"Wow, baby you're so warm and tight in here. Your hole is eagerly swallowing my finger. So hot. I wish you could see this." He says as his index finger bottoms out in me. He hooks it as he slides out and rubs something inside of me, triggering something I've never felt that makes me shiver with pleasure.

"Mmm, that feels so good." I moan, slack mouthed and paralyzed with lust. He inserts another finger, repeating the same initial discomfort before the pleasure takes over.

"Yeah your hole is swallowing my fingers with gusto." He says as he nudges my g-spot over and over. My leaky cock drenches the bed beneath me with my precum.

"I had no idea I could feel this good." I say as I rock against his invading digits.

"I can think of another internal massage technique that gets even deeper, buddy. I think you're really going to like it." He says as he climbs on top of me and lightly bites my neck a bit. "It's going to hurt a bit but it'll be worth it. Eventually the pain turns into pleasure. Want to try it out?" He asks me as his big dick slides up and down my crack.

"Yes daddy, please." I reply on autopilot, I would've agreed to anything at that point. I just wanted him to keep touching me. I felt so good underneath him and I knew that he would always keep me safe and never let anything hurt me. He's always been my reliable, trustworthy knight in shining armor and just cuz I'm an adult now doesn't mean that has to cease to be true.

I reach behind me so I can feel his dick and it feels huge in my hand and it feels twice as big as mine. As it rubs between my cheeks, the length is as long as my whole ass crack. I was a little worried at that point, how was all that going to fit inside of my virginal hole?

"Ohh, you're so big, daddy." I say as I continue rubbing his cock between my cheeks.

"Yeah I am, but I'll take it easy on you." He says as he gives me sweet, tender kisses on my neck and shoulders. "Hand me your lube, I wanna slick you up so I can slide right in. I wanna make you feel good."

I never thought I'd hear my dad talk like this before, it was something totally different. I reach into my bedside table and grab the lube I keep stored away. Handing it to him I hear him pop the top and drop some onto my hole. He smears it around with his thumb before inserting it inside of me. He repeats the process, coating my anal walls with as much lube as possible before he tries inserting his big dick.

He removes his thumb and I look back to see him squirt lube on his cock and rub it in. My mouth waters watching him jerk his fat cock. As excited as I was about daddy entering me, I was equally terrified.

He massages his cock head on to my hole, making slow circles and making me crave it. My eyes close and I moan, how do I want something so bad that I've never had? I flex my hole around him, trying to grab it so I can swallow it down my ass chute.

"You want it, baby? You ready for this cock?" Daddy teases me.

"Yes, daddy pleeaase." I nearly shout. I didn't mean to whine but he was driving me crazy with lust. I was so close to cuming and he hasn't even started fucking me yet..

"Okay, push out, it sounds weird but it helps." He says as he finally applies enough pressure to enter me. I push out as suggested and my prepped hole opens for his fat cock head. I squeal at the sudden pain and my entire body tightens. He stops right at the beginning to let my body adjust and I really needed that time.

I thought I was ready to take him but my body was so overwhelmed by the pain of the initial invasion that I was rethinking everything. I was taking deep breaths to try and calm myself.

"Oow, daddy it hurts." I say as neither of us move.

"I know it does, baby. It always starts like this, I'm sorry. I want to make you feel good. Will you let me?" He bends down just enough to resume planting kisses on my neck, shoulders and behind my ears.

How could I say no to the best man in the world? "Yes, of course. I'm sorry for being a cry baby."

"You're not, don't worry. Once your body adjusts, it's going to feel amazing. We'll get there. Mmm, you're so tight." He reassures me and it makes me feel a little better. Coincidentally making my ass feel better. Relaxing a bit, I was ready to see if I could take more of daddy's cock. "Mm, you feel so good."

I slightly raise my hips off my bed, taking in daddy's cock little by little so as to not overwhelm my tight anal walls. I wanted to make daddy feel good, he deserved a tight hole to spray his seed in. He does so much for me, I should repay the favor.

"Mmm, oh shiit." He says, grabbing my hips and letting me sink back onto him at my excruciatingly slow speed. Even moving at a snails pace I feel like I'm being split in two. We're both sweating by now from a mix of desire, stress and anticipation. My ass feels so full, I hope he's at least halfway in but I don't dare look.

"Rock a little bit. Move back and forth on it. You're doing great." He says patiently. I wish I was immediately a pro at this but my insides were on fire. I do as he says and push and pull on his dick.

Oh! There's that g-spot again. He nudged it and it jolted me alert. His cock found the switch that made my whole body tingle. I moved back and forth on him until I felt it again. It didn't take long before the sudden tingling returned and my entire body felt like it vibrated. I start moving a bit faster, trying to make that feeling happen consistently. Speeding up and making the strokes longer each time, I didn't even realize we were finally fucking.

I was so elated that my ass was swallowing daddy's cock with ease now that most of the pain had subsided. I was relieved I didn't have to back out, daddy didn't raise no quitter and now he was reaping the rewards.

"Mm, that's right baby. That feels really good. Is it good for you too?" He asks me as he starts meeting my thrusts, still depositing more and more of his cock into me.

"Yes daddy, you feel so good inside of me." I say as my ass clenches around his huge dick. I relax back onto the bed, allowing for dad to take over the movements.

His strokes are getting longer still and he leans forward and puts his arms under me and lays his chest down on my back. I feel his nuts slapping against me and finally his groin rests on my fat butt cheeks. Feeling like a footlong is stuffed inside of me, daddy grinds into me as his entire cock has finally gained entrance.

"Mmm." We moan together. Both enjoying the feeling of being physically connected like never before.

"I'm all the way in now. Are you okay?" He asks, concerned.

"Yes daddy. Fuck me." I didn't have to tell him twice as he pulls almost all the way out just to push completely back in. It was a crazy sensation, both uncomfortable and satisfying at the same time. The more he did it, the more he hit that crazy part inside of me that made me shiver with desire.

Each time he landed all the way in my, his hips smashed against the pillowy surface of my ass and he grinded into me. I was thankful to have such big booty cheeks so that he could enjoy them. And enjoy them, he did.

His pace quickened and he slammed into me harder and harder. Both of our breathing getting deeper and moans getting louder as my dad was relentlessly pounding into me. All I could do was stay stuck between him and the bed and that's all he needed from me. He was on a roll as he expertly took my virginity.

I was so turned on getting turned out by my daddy, there was no one else I could imagine giving it up to.

"Ooo daddy, Im gonna make a mess out of these sheets. You're gonna make me cum." I say as I felt the impending climax soon to overtake me.

"Yeah baby, cum for me. I wanna feel your ass squeeze my cock while you blast your load beneath you." He says in my ear, blowing hot air on my face. I loved having daddy this close to me, it felt so comfortable. So natural.

Feeling him slam into me was driving me wild. I was lost in a haze as my g-spot was slammed again and again, both of us nearly lifting off the bed with every powerful stroke my dad made.

I couldn't hold off any longer as daddy relentlessly slams my love button. I moan senselessly and feel my balls tighten and enter my body as they release their fluids. I feel it travel to my penis and shoot out onto the bed I'm smooshed against.

"Uuaauh-" I moan nonsense as my orgasm takes over my senses and my asshole clenches around Daddy's cock with a guillotine grip.

"Oh fuuuuck, baby you're so tight. You're gonna make me cum with you." He bites down on my neck and I feel his cock head expand before feeling a rush of liquid gushing into my hole. He moans so deeply as he squeezes me in his arms, drenching my insides with the same seed that made me.

His strokes cease as he slowly bounces against me, my fluffy cheeks acting as a small trampoline. "Damm baby, that felt so fucking good. I haven't came like that in forever." He says between planting kisses on my neck.

He starts to pull out and I push my ass up, preventing his exit. "No, don't. Not yet." I say as he stops and keeps his softening cock in me. "Stay inside me, please. It feels so good filling me up."

"Well okay, then." He says with a smirk. "Sounds like you discovered a new favorite past time, huh?" He says as he bottoms out in me.

"I guess so, maybe we can just order in and watch something here? We don't need to go out to celebrate my birthday." I say as I realize how horny I still am. "Besides, I can't play with my new favorite toy in public." I say as I grind my ass back against him.
