And one other I meant to upload a while back but didn't. Enjoy!

>you could hardly wait, with it being your birthday and dear mother had promised a very special gift
>hours passed by excruciatingly slow, always leading you to peek out the doors
>soon enough, there was a light rap at the door, leaving you excited as you pulled it open
>"There's mama's boy~" Celestia cooed out, walking in and giving your cheek a nuzzle
>"Ready for your special surprise?" she asks, her eyes seeming to size you up carefully
>of course you were!
>"Then be my little ray of sunshine and let's..get you more comfortable.."
>the expression lost on you for a moment, but only a moment
>her head moved low, her mouth tugging at the hem of your pants while she looks up with a wink
>there were special sensations growing below with her proximity so close
>you start undressing, leaving your form as bare your dear mother's, sans the underwear
>"Those need to go, too~ Can't give you your growing up gift with those on," she teases, kissing to your stomach and taking the underwear in her mouth
>her head moves down, leaving you a bit tense as your lower half is utterly exposed to the goddess, and swiftly changing before her
>"That's my boy~" she coos, her horn brushing your chest as you lift your head
>the sudden sensation of your length being enveloped by the best warmth you've felt makes you elicit a small moan
>what was going on?
>why hadn't she made you feel this before? it felt good but..strange
>there was a pressure under the belly of your member, rolling up and down as you felt the warmth begin to move
>up and down your firming pole, you felt the tender care of your sun mother's lips ease into a steady rhythm
>it felt..amazing!
>there was hardly a reason to speak any words, though you knew you couldn't with this initial phase of pleasure
>the hold along your loins tightened and eased up repeatedly, moving back and forth as your felt her mane tickle your thighs and legs
>her horn grazed gently to your chest, turning this way and that as you felt different amounts of pleasure course through your body
>it felt like you were going to explode if she kept it up
>why would mama hide such a fun..game? was this a game?
>your quivering legs and subconscious hip movements were enough to have her ease back off very slowly
>the wet pop as you left her muzzle sounded as good as it felt, leaving you panting and looking down to wonder why things had stopped
>the wetness coating your firm member had you in awe
>but it was the idle strand of saliva leading from the tip to her mouth that let you know what had happened
>you ask in a stuttered breath what game she was playing with you
>"Oh~ It's no game, sweetheart. It's just a way to show my boy has grown up so well.. Just remember..if it gets like this again, come to mama and I'll take care of it."
>you nod quickly, happy to know she accepted you growing up and loving you still
>when the white alicorn began turning around, your attention was instantly drawn to more aspects of her body than before
>how had you not noticed how round her backside was? or how..lovely it appeared?
>it seemed Celestia noticed your wandering eyes and gave a soft giggle before her body eased back, pressing her rump to your chest
>"Sit down, honey. Let's make you a real man today~"
>obediently, you follow her rather insisting pushes with her rear, enjoying the feeling quite a bit
>you manage to finally sit down and lean back, almost worried at the eclipsing sun hovering above your body
>there was nothing to worry about, though
>her hinds lowered as she eased herself down and grazed your head with her tail more than a few times
>"Ready, my little man?"
>you give one more enthusiastic nod before she smiles sweetly and gives a playful bump to your chest with her flank
>you lay back after taking the hint and glance down to see the glistening wink between her legs
>you had seen the area a few times, but not like this
>in fact, you hardly remember being this..infatuated with it
>"It's all for you~" she whispers, her hinds straddling your lower body as she positions herself above your lap
>"Sweetie~ This is going to feel really nice.. So, don't worry when it feels like something's going to happen, okay?"
>you aren't sure how to take this supposed warning but agree and watch eagerly
>"Also, take yourself down there and..point it up at mommy.. It'll make it easier~"
>you grasp the base of your length, tilting you up and pointing it towards her unguarded loins
>"Good boy~" she says softly, those hips moving down gently until the first bit of contact is made to your member
>slowly, those slick folds spread and ease around your recently polished shaft
>every small touch is euphoric and only intensifies the more she lowers down
>inch by inch, her body welcomes yours, sinking down as you enter your dear and beloved mother
>it was impossible not to squirm under her, writing in pleasure at just the initial penetration
>"Oh! Oh, you're such a big boy.."
>there was a moment of reprieve, her rump now flush with your lap
>the sensations didn't stop, able to feel every twitch and squeeze within as you pet along her royal flanks
>"Mm, it's okay, sweetheart~ Mommy's going to do the work for you this time~ Just relax.."
>you accept and thank her, resting beneath the bright princess as she squirms in your lap a few times
>each motion clenches and rubs along your sensitive flesh like never before, coating you in the mare's slick juices
>then came the best moment ever
>that round plot rose, gliding those snug walls up your flesh and clapped back down into your lap
>her passage swallowed every inch of your length in one fell swoop
>again, she rose and lowered back down with that cushioned backside landing perfectly into your lap
>it was a new feeling, and wonderful one at that, as she began her first ever ride with her growing boy
>the mare bounced and wiggled her plump posterior down against you repeatedly as her walls clamped and released repeatedly
>her winking entrance repeatedly accepts you, slipping up and down as if you were the last thing to grace her inner presence
>"Oh! Oh, yes.. Just.. Just relax for m-mama!" she tells you, riding a bit faster
>you can hear the lewd slurps and slorps of her depths constantly pulling up and pressing back down around you
>as her body quaked against your own, you can't help but feel that familiar tension rising again
>mama knew best, and she had said to relax and let happen
>you curl your toes as you feel her work along you more and more, bouncing and looking back to you with an expression you've never seen before
>her hips roll and press, doing their best to draw out the very first essence of your welcome into manhood
>it got hotter by the second, as if you were closer to the sun than usual
>her wings helped lift and lower her now, the sounds becoming louder as she smiled to you
>you weren't able to hold it back
>not yet, anyway
>your hips lifted as she pressed back down, burying you as deep as possible for the time being
>whatever was happening, it was hard to focus as you felt yourself twitching within her and then the sudden rush of release
>it was different than when you urinated, so it had to have been something new
>at the same instance, Celestia closed her eyes and threw her head back in a loud moan, clamping down onto you and keeping whatever had expelled from you body deep inside her
>minutes had passed, but you hardly knew how many
>both of you were a sweaty mess that smelled of..something strong
>you laid there for a while, just enjoying the warmth embrace her lower body had on you before she eventually pulled off with a slick pop
>"You did very good~" she praised you, turning around and wearily kissing your brow
>"It's been ages.." she commented to herself and nosed along your cheek until she laid down with you, resuming your usually cuddling positions
>you give her your thanks and want to ask her so much, but the whole moment had made you weary and weak
>"We'll talk all about it when you rest up, my little man. Mm, or should I call you my big man now?"
>you both give a weak laugh and hug close, drifting of together
>you certainly did love your mother
