Anon's Birthday Present

A plethora of female Warframes surrounded Anon at the dinner table. A German triple chocolate fudge cake with ice cream filling sat upon a raised plate, decorated with lit candles. The Warframes sang an archaic song in celebration of the date of his birth, and tt the end of the song Anon exhaled and blew out the candles. They all cheered excitedly and congratulated him.
  "Are you ready for your prize, Anon?" Asked Banshee.
  Anon nodded. One by one the Warframes got down on their hands and knees and presented their swollen vulva to him, then simultaneous spread their labia. Anon's eyes widened and he took a rushed bite of the cake.
  "Whomever you choose shall give themselves unto to at your request for the rest of one Earth year." Explained Banshee.
  Ivara, sat at the far right end, threw her hips against the Warframe to her left and caused a domino effect of jiggling buttocks'. Anon's heart rate rapidly increased and his penis engorged with blood. He fell to his knees behind the red and grey Warframe Trinity and shoved his middle and index finger into her moist canal, and by twisting and curling his fingers he prepared her for penetration. First, however, he lowered his head and extended his tongue to taste the inside of her vagina. The taste sour, yet sweet, coated his tongue and perforated his nostrils. A thick layer of saliva drooled and blanketed her vulva which in turn dripped inside of her.
  "Come on, don't make me wait any longer." Begged Trinity as she brought her open palm down on her right buttock.
  Anon stood on his knees and plunged the head of his penis as deep as it would go. The blazing hot walls gripped his shaft and tugged it back inside with every thrust, milking pre-cum from his urethra. The Warframes waited, their butts still raised in the air, for their turn.
  All the while thrusting in and out of Trinity, Anon toyed with Zephyr and Mesa's pussies. The three Warframes moaned from his attacks and pushed themselves back against his appendages, enthralled with the pleasurable sensations that rippled through their bodies.
  A meager, yet hearty, flow of semen shot from Anon's penis and pumped inside of Trinity. The tender canal clamped down on his organ and held it in within, not allowing him to spill a drop.
  Anon's member remained hard, in fact it only pulsated with desire more after his ejaculation. He looked back at the cake and the small portion cut out of it, then licked a spec of chocolate frosting from his top lip before moving on to Ivara.
  As Anon scooted to the end of the row Ivara's hands moved slightly upward. Instead of spreading her labia, they spread her buttocks to better expose her winking anus. It was like a dream come true. Anon wiped Trinity's gooey slime around Ivara's anus and thrust his hips forward to bury his entirety within her rectum. Ivara yelped and moaned, then pulled herself forward. The sphincter opened around the rim, closed around the tip, then expanded to consume him down to the base again and again. The muscular anus squeezed his shaft with a ferocity unmatched, and even though he had just ejaculated, the feeling welled inside of him.
  Anon's organ repeatedly flexed and he clenched his kegel muscles in an attempt to stave off his orgasm. The act failed miserably. Six strands of stringy semen shot out and stuck to the inner walls of Ivara's rectum.
  Then, with his first two choices down, he scooted to his right and plunged himself inside of the next Warframe, then slowly worked down the line.
