Thirteen: second mating

After all the vampires along with their guards left promising to return within two weeks to begin training, preparing for what Sir Night Eye had seen in a vision.  Shoto took Izuku back to their combined room.  Izuku had moved in with his potential mate after their first mating.  Shoto planned to complete the second part to the mating process.  This way they could begin to train Izuku how to use his newfound powers that he would get because of the second mating.

"Shoto......." Izuku asked softly as the two entered the room.

"Is there something wrong Izuku?" asked Shoto as Izuku went to sit on their large king size bed.

"You never told me the reason why there is three parts to the mating ritual." stated Izuku bashfully.  Shoto sat down next to Izuku pulling him close before laying down onto the bed causing Izuku to straddle him.

"The reasons are simple enough to understand.  The first part to the mating was to mark you as mine.  It also connects us mentally as we can speak with each other telepathically.  This is the reason why you maybe the only one to break through my rage.  As my mate and with you being marked by me, even in a raged state, your voice will be able to reach me and break me out of my rage." Shoto explained as he nipped at his mate mark. 

The mark was of a golden crown with red and blue tribal lines.  When Izuku became a vampire, he would mark Shoto with the same mark but the color of the lines would be different.  Izuku found himself getting turned on with Shoto lightly nipping at the mark that he moaned out loud.

"Shoto......."

"The other reason to the first part was to show everyone who you belong to.  Now for the second part of the mating, more physical changes happen.  Your body changes allowing you to support and carry children.  You will begin to ovulate much like a female does.  Only without the monthly bleeding and cramps.  You won't be able to physically give birth as your body isn't built for that but, you will be able to carry our children until they are ready to be born." stated Shoto as he lifted Izuku's shirt off of his body and unbuttoned his pants.  Shoto's fingers traced over Izuku's stomach as he placed a light kiss on the belly. "You will be able to carry our child for six months until we have to cut them out from you." Izuku bucked his hips rubbing his hard on against Shoto's.  Shoto lightly kissed and began to suckle on Izuku's nipples earning a sharp gasp in pleasure from the human.  *I personally can't wait until you produce milk.  I bet it will just taste as sweet as you.* Shoto growled out mentally.  Izuku moaned out Shoto's name as his hard on became even harder.

"Shoto......  Please....... Stop teasing........" Izuku panted.  Shoto grabbed Izuku by the hips as he rolled his mate onto the bed ripping off Izuku's pants and boxers in one swift movement.

"Now during the second part of our mating when you and I reach our climax, you will feel power slam into your body.  That is the power that you will have as a supernatural." stated Shoto as he began to prep Izuku.  Izuku whimpered and pleaded for Shoto to hurry.

Shoto stopped as he removed his own clothing admiring how Izuku's eyes were clouded with lust.  His cock was leaking with precum and twitching madly for relief.  A light layer of sweat clung to Izuku's body.  Izuku's nipples were swollen and hard from Shoto licking and nipping at them.  His lips were bruised from the kisses.

"Beautiful......." Shoto growled in a dark voice as his eyes flashed red.  "Everything about you tastes so sweet that I can barely contain myself." Shoto pushed his hard cock deep into Izuku causing the human to scream out in pleasure and pain.  "Damn you are so tight Izuku." growled out Shoto.

"Shoto........  Move.......  Please........" moaned out Izuku as he bucked his hips.  Shoto moved in and out slowly brushing ever so slightly against his prostate.  "Ah.......  Shoto.......!" Izuku cried out.

*Now during the third part of the mating it will be much more intense.  You will be fertile as I will be able to get you pregnant.  You will also be transforming into a pure blood.* Shoto told the human mentally.

"Shoto......  Faster......  Harder......" Izuku cried out.

Shoto obeyed his mate's cries and pleads as he moved harder and faster causing his wings to unfurl from his back.  His fangs to fully lengthen and his eyes to glow blood red.

"Izuku......." Shoto growled as he sank his fangs into the mate mark on the hollow of Izuku's neck.  Izuku cried out as he held onto Shoto chanting out the vampire's name as he begged him to go faster and harder.  Shoto complied with Izuku's wishes as he used one of his hands to cut open his neck allowing Izuku to feed.  Izuku latched onto the open wound causing Shoto to growl in the bite as he picked Izuku up off the bed nearly slamming him against the wall.  Izuku's legs wrapped around Shoto's waist as he met the vampire's thrusts with his own.  Shoto could feel Izuku's inner walls clamping down on him hard.  They were both close to reaching their climax.  Shoto freed one of his hand grabbing a hold of Izuku's erection and stroking it in time with their wild thrusts as he continued to hit Izuku's sweet spot.  Izuku threw his head back moaning out loud.

"Ah......  Yes........  Shoto........!" he cried out.

*Cum for me Izuku!* Shoto commanded mentally.  Izuku cried out as he came hard.  Shoto released his fangs from Izuku's neck snarling out as he came.  Shoto could feel Izuku's power slamming hard into them both causing the orgasm to last longer than normal.

Izuku found the strength to push Shoto back onto the bed as the human began to ride him hard.  Shoto growled out in pleasure allowing the human to do as he liked.  Green lighting began to dance around Izuku's body as his veins began to glow with energy.  Need and desire slammed into Shoto as he thrusted up into Izuku's thrusts hitting the one spot that caused Izuku to shout out in pleasure.

"Ah......  Shoto.......  More......." cried out Izuku as his thrusts became faster and harder.  "There......  Faster...... Harder......"

"God.......  Izuku......" growled Shoto.  The power was building along with the need to climax and cum.  "Shit.......  Izuku......." Shoto cried out as he could feel his own power surging forth.  Izuku began to chant out Shoto's name as his toes curled.  "Fuck......  Cum for me.......  My mate!" Shoto growled out.  Izuku cried out coming harder than ever before as the power slammed into them both causing Shoto to cum hard into his mate before they both collapsed in exhaustion.
