Spa Day for Degenerate Princesses

Expiry: Never

  1. 1.
    “Sunday! Eeeeeeee!” Princess Luna squealed as she rushed out of her bedroom. Her legs raced as fast as they could to her sister's chambers as the lunar mare continued to bounce with excitement. “Sister! Today is the day!” Luna charged her horn and opened the doors to the bedchamber with a mighty slam. “Our little spa session!” Luna exclaimed as she shouted loud enough to wake half of Canterlot.
  2. 2.
     
  3. 3.
    DONK
  4. 4.
     
  5. 5.
    “ACK!” Princess Luna hissed as she bent her neck down to rub her head. “That will surely leave a mark. Why in the world haven't we remodeled this castle and the door frames after so many centuries?”
  6. 6.
     
  7. 7.
    “Because, my loud and obnoxious sister, it's YOUR neck and ONLY your neck that is longer than most ponies.” Princess Celestia grumbled as she rolled out of bed. The springs groaned as the wide princess left her bed and waddled over to her balcony.
  8. 8.
     
  9. 9.
    “Strange you say that, since you have no trouble hauling that cart wide rear of yours through the castle!” Luna teased as she aided her sister with their celestial duties. “Then again, I'm sure you did most of the breaking down yourself, fat ass.”
  10. 10.
     
  11. 11.
    Princess Celestia scoffed as she waddled back inside. “Keep this up and I'll simply forget my plus one for this exclusive spa treatment, Lulu. Although I always wonder how you keep that bloated head so high with such a noodle neck.”
  12. 12.
     
  13. 13.
    “Hey! It's dignified!” Luna pouted as she shot her face towards Celestia. “We must have a tall, imposing stature to strike fear in our enemies and show strength in front of our subjects.” Luna puffed out her chest as she walked out of the bedroom as tall as she could manage.
  14. 14.
     
  15. 15.
    DONK
  16. 16.
     
  17. 17.
    “Dang it!”
  18. 18.
     
  19. 19.
    “Duck, for goodness sake. One of these times, your horn is gonna bust off you silly mare.” Celestia giggled as she led the way to the dining hall.
  20. 20.
     
  21. 21.
    Celestia slid an extra chair or two over to her side of the table while Luna sat near the middle. “Just a light breakfast today. We have an early appointment.” Celestia told her servant.
  22. 22.
     
  23. 23.
    “A light breakfast? So only a dozen cakes?” Luna chuckled as she tossed a few apples into her mouth. Luna moaned as she swallowed them whole, sending three giant bulges sliding down her throat.
  24. 24.
     
  25. 25.
    “Must you eat like that? It creeps me out to see your already gross neck do such vulgar things...” Celestia stuck out her tongue in disgust.
  26. 26.
     
  27. 27.
    “Oh, what if I do this?” Luna smirked as she spiraled her head about and contorted her neck like a spring. “Does that creep you out?” She said with a goofy grin.
  28. 28.
     
  29. 29.
    “Is your bird brain getting enough oxygen up there? Should we send a team of scouts to climb up and inspect your coconut skull?” Celestia sighed as her sister continued to contort and stretch her neck out to eat.
  30. 30.
     
  31. 31.
    Celestia wasn't kept waiting long as a few cakes were pushed onto the table. “Good, a proper distraction from this carnival show.” The heavy princess wasted no time in shoving her muzzle right into the nearest cake and gobbling it up. It was Celestia's turn to moan as her stomach was flooded with sugary sweets.
  32. 32.
     
  33. 33.
    A chair groaned as the greedy princess chomped through her meal. Such desperation was ignored as Celestia continued to glut herself silly. Her face was slathered with frosting as she swapped from cake to cake.
  34. 34.
     
  35. 35.
    With the platters gone, Celestia leaned back and belched hard. A small lick of her lips finished off the rich, fattening meal. “Ah...ready to go, LunaaAAAAAA?!” Celestia screamed as her chairs collapsed under her titanic ass.
  36. 36.
     
  37. 37.
    “Pfffaaaahahahahaha! Not even the most powerful magics could lift you up from that spot, sister. Now who is the carnival freak show?” Luna smugly stood up and departed from the table with her neck straight and her head held high.
  38. 38.
     
  39. 39.
    THWONK
  40. 40.
     
  41. 41.
    “ACK!”
  42. 42.
     
  43. 43.
     
  44. 44.
     
  45. 45.
     
  46. 46.
    Fed and ready, the two mares were off in their carriages. Princess Luna eased herself into her seats by allowing her neck to slump against the plush pillows inside. The stallions set to pull Celestia's cart were already sweating bullets as they felt the carriage tilt from the sudden weight shift. Luna smirked as her ride took off, leaving Celestia in her dust.
  47. 47.
     
  48. 48.
    “Sure you aren't using enough stallions to pull your lazy butt around? They might expire from exhaustion at this rate.” Luna teased as Celestia finally waddled up to the spa.
  49. 49.
     
  50. 50.
    “Oh har har. Very funny.” Princess Celestia rolled her eyes as she prepared to open the door to the spa. “Please be civil while we are guests at this very nice, very private spa. While our subjects are no strangers to our banter, I'm looking forward to a stress free visit.”
  51. 51.
     
  52. 52.
    “Agreed. We are here to relax, after all.” Princess Luna smiled as her sister opened the door. Her face tightened as Celestia waddled into the spa and promptly wedged her wide hips right into the frame. “Um...Do..do you need any help, Celestia?” Luna sputtered with her teeth clenched into a joyous smile.
  53. 53.
     
  54. 54.
    “Please?” Celestia blushed as she struggled to pull herself inside. Luna reared onto her hind legs and pushed her hooves deep into Celestia's rump.
  55. 55.
     
  56. 56.
    “One...two...THREE!” Luna shouted as she used her magic and forelegs to shove. Princess Celestia wiggled her body and popped out of the door frame. The pear shaped mare fell onto her belly with a grunt while Princess Luna's head slammed into the top of the frame with a dull THUMP.
  57. 57.
     
  58. 58.
    Both mares were moaning as they struggled to stand. “Oh my goodness! I'm so sorry, Princess Celestia and Princess Luna. We'll have that door adjusted before your next visit!” The clerk at the front counter rushed over to help them to a chair. “Please, rest a moment as we prepare your rooms.”
  59. 59.
     
  60. 60.
    Celestia made sure to grab at least three chairs and sat down. “I really need to cut down on the cakes...” Celestia blushed as she picked up a nearby magazine. “Mmmm, Top Pastry From Around Equestria.”
  61. 61.
     
  62. 62.
    “Really? What kind of stuff are they showing off?” Luna craned her neck past Celestia's shoulder to look on. “That one looks good. Do the chefs already make something like that?”
  63. 63.
     
  64. 64.
    “Yes, it's quite tasty...Ohh, look at this one.” Celestia drooled as she jabbed as a gigantic cake. She turned the magazine sideways and shuddered as the pages unfolded to show off a cake bigger than a house.
  65. 65.
     
  66. 66.
    “So much for that diet.” Luna muttered to herself. “Self control, sister. I can see you getting bigger just from that image alone.”
  67. 67.
     
  68. 68.
    “Don't care...I NEEEEED it, Lulu.” Celestia licked her lips and rubbed her growling tummy.
  69. 69.
     
  70. 70.
    “Princess Celestia? We're ready for you.” One of the workers called her from the back.
  71. 71.
     
  72. 72.
    “Oh, lovely. See you soon, Luna.” Celestia slowly stood up from her seats, leaving her sister to dig through the pile of magazines on the table. The wide mare continued to drool all over herself as she waddled to the back. Thankfully, the frames and the walls only scraped her thick hips as she jiggled to her personal spa room.
  73. 73.
     
  74. 74.
    “Welcome, Princess. What would you like today? A soak? Massage? Perhaps a little of both while we feed you?” The workers smiled as Celestia's tummy grumbled and growled.
  75. 75.
     
  76. 76.
    “That all sounds lovely. Perhaps a small soak first for my coat.” Celestia grinned as the workers eased her into a large tub full of bubbles and sweet smelling oils. She closed her eyes and sat back as the warm water soothed her body and relaxed her to the core.
  77. 77.
     
  78. 78.
    “Open, please.” Celestia did as she was told and opened her mouth. A thick, rich, delicious slice of cake was eased into her mouth. The princess cooed as she savored the gigantic piece. A wet cloth dabbed at her cheeks as she chewed and swallowed, keeping her clean while she ate.
  79. 79.
     
  80. 80.
    Celestia dissolved into the tub as she completely relaxed. The tingles of the warmth made it hard for her to gauge just how full she was but it was no matter. Her stomach bloated outwards with each piece, sending each massive load of calories straight to her hips and butt.
  81. 81.
     
  82. 82.
    “Mmm...this is fantastic.” Princess Celestia cooed. She moaned in delight as a pair of hooves dove into the pool and rubbed her belly. “Yeeessssss....” Celestia moaned before another slice of cake was stuffed into her maw.
  83. 83.
     
  84. 84.
    Time blurred away. Hours seemed to pass for the piggy princess as she simply sat and ate. She moaned and belched between huge bites, her hind leg twitching as several hooves rubbed her belly. More and more cake was eased into her mouth until her stomach breached the surface of the pool.
  85. 85.
     
  86. 86.
    “Ohh, our big, sexy princess is getting too big for the soak. Time for your massage.” Celestia grumbled as she opened her eyes. Indeed, her swollen gut was exposed like a soft island alone in the tub.
  87. 87.
     
  88. 88.
    “Fine. As long as I can keep eating.” Celestia grunted as she struggled to stand back up. Her legs felt like jelly as she struggled to waddle to the reinforced massage table. It groaned slightly as she flopped on top and shoved her muzzle into the hole.
  89. 89.
     
  90. 90.
    “Fantastic. Let our hooves work their magic.” The masseuses blushed as they began pouring oils all over Celestia's back and rear. Their princess cooed in delight as she felt every set of hooves squish into her flabby rump.
  91. 91.
     
  92. 92.
    “Oh, by the sun.” Celestia moaned as she felt her body wobble and squish under a dozen professional hooves. She couldn't help but blush as her subjects admired every inch of her body. No roll of blubber was left untouched as they massaged the oils into her body until her coat shined.
  93. 93.
     
  94. 94.
    A small cake was placed near Celestia's face. “Lovely, just what I needed.” The glutton moaned as she pushed her muzzle right into the cake. Without the attendants to dab away the mess, huge globs of frosting clung to her mouth and chins.
  95. 95.
     
  96. 96.
    The masseuses gasped as they felt their princess grow fatter right under their hooves. “My, Princess. You're starving! Are they feeding you right at the castle? Why not stay here and let us feed you and pamper you right.” They giggled as Celestia eased her face away from her cake to belch out a bit of pressure in her bloated gut.
  97. 97.
     
  98. 98.
    “Thank you for the offer...but I cannot stay for too much longer. I have a country to run, after all.” The spa workers groaned before really sinking their hooves into Celestia's rear.
  99. 99.
     
  100. 100.
    “We'll just have to make sure we enjoy every moment.” They teased. Desperate hooves groped and kneaded her flabby rump, making Celestia shudder as she swallowed up another cake. “Our big, fat piggy princess needs another cake! Hurry!”
  101. 101.
     
  102. 102.
    Before any of the attendants could fetch another cake, the table began to whine and groan. “Oh no...is everything alright?” Celestia barely managed to ask before the sturdy table snapped. Her body fell to the ground and landed hard, sending her body jiggling for minutes before the sea of white blubber could be calmed.
  103. 103.
     
  104. 104.
    “I suppose my massage is over.” Celestia blushed as she struggled to her hooves. A few mares couldn't help but bite their lip in agony as they watched her immense rear wobble away. “Drat...” Celestia's face burned even brighter as her hips smooshed against the walls and impeded her waddle on her return from the waiting room.
  105. 105.
     
  106. 106.
     
  107. 107.
     
  108. 108.
     
  109. 109.
     
  110. 110.
    “Princess Luna, we're ready for you.” A masseuse called out to the awaiting princess.
  111. 111.
     
  112. 112.
    “Goody! I do love these sessions of ours. Luna smiled as she stood up and rushed to the back of the spa
  113. 113.
     
  114. 114.
    THONK
  115. 115.
     
  116. 116.
    “Oh dear, are you alright, Princess?” The mare rushed up to inspect the tall alicorn.
  117. 117.
     
  118. 118.
    “Won't be the first time today.” Luna blushed as she ducked under the top of the frame and kept her head low. “I simply must find a spell to widen and lengthen doorways sometime soon.”
  119. 119.
     
  120. 120.
    “Another time, my lovely, tall princess. We have the machine ready for you.” The masseuse opened the door to the private room, revealing a bed with straps and a small table next to it. “We've swapped out the straps with softer bindings, added a headrest and smoothed out the tugging process. Along with a new helper.”
  121. 121.
     
  122. 122.
    Luna cooed as a buff stallion walked over to a giant wheel next to the bed. “Whenever you are ready, Princess. I aim to please.” He rotated the wheel a bit and smiled as the small table slid away from the bed.
  123. 123.
     
  124. 124.
    “Fantastic! I can't wait.” Luna giggled as she laid upon the bed face up and strapped herself in. She placed her head onto the table and moaned in delight as the head rest hugged her skull. One last strap in place with her magic and she was ready.
  125. 125.
     
  126. 126.
    “One final thing.” The stallion offered a mouth guard to Luna. “Bite down on this. Just in case.” Luna did as she was told, stuffing the protective guard in her mouth.
  127. 127.
     
  128. 128.
    “Are you ready, my princess?” He offered one final warning as his hooves gripped the wheel. She nodded as best she could under her restraints.
  129. 129.
     
  130. 130.
    “I shall begin. If it becomes too much to bear, shoot a spark out from your horn or hit the button near your hooves.” He took a deep breath and began to turn the wheel. Princess Luna looked down and smiled as her body was drifting away from her head as the table pulled her neck tight. The stallion was forced to stop as Luna met her limits.
  131. 131.
     
  132. 132.
    With a mighty grunt, the wheel operator pulled hard. Princess Luna moaned as she felt the tension building inside the core of her neck. Slowly, the small table began to move away from the bed. Luna looked down and smiled. “Ahhh....this is most satisfying.”
  133. 133.
     
  134. 134.
    Luna could feel every new inch of her neck as she was forced to grow taller and taller. The air was filled with the sound of stressed rubber as the stretchy princess was tugged and pulled about. She squirmed in her binds as the wheel operator stopped. “Is this enough for today, Princess?”
  135. 135.
     
  136. 136.
    “Don't you dare stop! I need to be the tallest thing there is!” Luna moaned as she felt the table drift away from the bed once more, ensuring a few more inches were added to her already imposing height. “Mooooorrrrreeee.” Luna begged.
  137. 137.
     
  138. 138.
    The attendants watched as Luna was nearly pulled apart. Her neck had easily doubled in length and had begun to droop down between the huge gap between the headrest and the bed. “Princess Luna, we've reached the safe limits of the machine. Do you still wish to continue?”
  139. 139.
     
  140. 140.
    “One....one more inch?” Luna pleaded. She watched as the remaining attendants placed their hands on the wheel and counted out loud. The wheel was pulled hard, yanking on Luna's neck with incredible pressure. A loud crack filled the room as the tall princess shot up another inch in seconds.
  141. 141.
     
  142. 142.
    “Princess! Are you alright?”
  143. 143.
     
  144. 144.
    Luna yanked the protective mouth guard out with her magic and let it drop to the floor. “Ohhhh yeeesssssssss.” Her magic drifted down the the straps and released her from her position on the bed. “Now, to see how tall I am.”
  145. 145.
     
  146. 146.
    Luna strained her neck as best she could. “Hnnnnnnnnggggg! Hmmmmmmph! Blast it!” She stomped in defeat as her head refused to move. It was still snug in the headrest and no amount of effort could budge it.
  147. 147.
     
  148. 148.
    “You know it doesn't work like that. You'll need a few days or even weeks to build up the muscles in your neck again.” The closest masseuse giggled as she helped Luna remove her head from the table. “For now, rest and let us help the healing process.”
  149. 149.
     
  150. 150.
    The team of ponies eased Luna into a nearby tub and let her body rest in the hot water. A special shelf allowed Luna to sprawl her neck in the water without fear of her dunking under the water. Dozens of hooves groped and massaged the limp noodle neck while a unicorn began to cast a few spells. The relaxed princess sighed under the water and took a deep breath from her nose.
  151. 151.
     
  152. 152.
    Luna closed her eyes and smiled. She could feel the new vertebrae setting into place while the muscles slowly strengthened. She couldn't help but breathe through her mouth and form bubbles in the hot tub. The attendants knew how to press Luna's buttons, ensuring for a relaxing massage.
  153. 153.
     
  154. 154.
     
  155. 155.
     
  156. 156.
     
  157. 157.
     
  158. 158.
    Princess Luna walked out to the waiting room with care. The spells and massage had done well to strengthen her muscles but her neck wobbled about with every step. “Tia? Are you done with your massage?”
  159. 159.
     
  160. 160.
    “Yes I am. Are you ready to go home?” Celestia asked from her corner of the waiting room. Four chairs were placed under her gigantic rear with a fifth nearby in case one gave out. “I'm starving. Hopefully the chefs can recreate some of these cakes.” Celestia cooed as she held up her cake magazine.
  161. 161.
     
  162. 162.
    “Sister, please. You had enough trouble navigating the spa and now you want more?” Luna did her best to hover her head around Celestia's ears. “I know you have them feed you cake while you get a massage. How are you even hungry?”
  163. 163.
     
  164. 164.
    “They are SNACK sized cakes, Luna. Can't a mare enjoy herself and indulge like we just did?” Celestia smirked as she opened the door to the spa. “Besides, exiting a building is no problem.”
  165. 165.
     
  166. 166.
    The solar princess smiled as she teleported out of the spa. “Ah, a well thought out plan, sister. Now what happens when you miss and ponies mistake you for the actual sun?”
  167. 167.
     
  168. 168.
    “Better than being mistaken for a giraffe that sat in black paint, Miss mile neck.” Celestia giggled as she forced herself back into her carriage.
  169. 169.
     
  170. 170.
    “You wont be laughing when all the stallions visit MY bedchambers and not yours, you rainbow maned cow!” Luna huffed as she eased her rubbery noodle neck into her ride. Half of Canterlot could hear them bickering on the ride back to the castle, forcing everypony to simply roll their eyes.
