Featuring: Original character and Medb
Randall could still remember the Fifth Singularity as if it were yesterday. Waking up to find North America in a warzone and nurse, also Berserker-Class Servant, Florence Nightingale about to sever one of his limbs, meeting Cu's teacher Scathach and fighting a corrupt version of his student created from the Holy Grail by Queen Medb, a Rider-Class Servant. Even with her summoning 28 Demon Pillars in an act of defiance, Chaldea and the resistance came out on top over them and Cu Alter, thus winning the war.
However, Randall has his hands full when he summoned Medb into Chaldea. He can still remember the dumbfounded look on Cu's face and the eye twitching from Scathach when Medb clung to the Master like she does to Cu. At first Randall thought this wouldn't be so bad, but then he discovered she would jump him Cu whenever she sees either of them. This already annoys Randall since Medb was interrupting his bro time with Cu when he wasn't screwing Scathach.
He was tempted to sic Atalanta on her when Medb jumped Randall again (this time in front of Jack the Ripper no less! Granted she was a killer but still a kid nonetheless and Atalanta was not going to let that slide when he told her) but Mash convinced him to let things play out to let Medb adjust to Chaldea. Eventually you send her off with Saber Artoria and to grind for materials. He'd expect them to be gone for a while.
"So," Randall crossed his arms and stared at the feminine figure smiling as she sat on his bed. Nude and exposed for him to see. Medb somehow had access to him room and waited for him to exit the shower. "What brings you here?"
"Simple Master." Medb smirked and brushed her pink her aside so her pink nipples can be seen. "I've heard that you've been fucking that old hag for quite some time to replenish Mana and I want to see it for myself if the rumors are true." Randall knew she was talking about him and Scathach and it was not surprising Medb wanted to learn given her status as a sex maniac.
"..... think you can handle it? Randall took the challenge and took off his towel, letting Medb see his massive 12-inch cock that rises up to show off. Medb licked her lips and laid on Randall's best stomach while facing away from him before turning to give him a seductive look.
"Let's find out shall we?" Medb spread her legs, revealing her glistening pussy and inviting Randall in. Without hesitation, Randall jumped on top of her and inserted all of his cock in her. Medb moaned as her pussy was instantly filled up before squealing as the Master starts thrusting his cock in and out of the Rider-Class Servant. Hands moving grope her smaller but still bountiful D-cup breasts as Randall nibbled on her neck.
"Yes~! Just like that!" Medb moaned as she clutched the bedsheets as her Master dominated her in bed. Even after having many sex with other men, Randall was still big enough to leave Medb in awe and took it like a champ. Her eyes rolled up as Randall's movements were hard and fast that Medb almost passed out from the force he was exerting.
This went on for a few minutes before he slams his cock deep into Medb and groaned against her neck as he cums inside the Celtic Queen. Medb cried out in pleasure as hot cum pours into her pussy, making her go blank and painting her pussy white. His fingers digging into her tits as they he rode his orgasm out until it ended. He remains hard in her however and had another idea.
Medb yelped as she was flipped on her back before moaning as Randall starts to resume fucking her in missionary position. She gasped as Randall reached for her tits again, this time he brough his face between them and sucked on her nipples while maintaining his hard and fast pace. She wrapped her legs around his waist to prevent him from backing out even if he wanted to, not that he ever will.
Randall teeth grinded against the tips of her nipples and teases the Servant by pulling them which made Medb scream and clenched her pussy around his cock as a result. Medb saw stars as she was overwhelmed by Randall's strength. She had underestimated him based on rumors and now her pussy was paying for it.
She had little time for such thought before she arched her back and screams out as she came first, squirting her love juices all over the pulsating cock while clenching. Such actions made Randall's cock swell up and exploded in the Servant, delivering another round of semen into her. Some start to leak from her stuffed womb since she'd already met the threshold of how much she can take. Yet Randall decided to hurt her where it hurt most.
"Is this the best you can do? Scathach last much longer than you and you're a nymphomaniac." Randall challenged her, grinning as he stares the panting Servant as she tried to catch her breath. She felt her pride being jabbed at and that he claimed Scathach was supposedly better when having sex. As if she'll let that old hag win!
With a growl, Medb pushed Randall on his back so that she's the one on top and begins bouncing her hips up and down, living up to her Rider-Class status as the Celtic Queen rides the Master like a horse. Randall grinned as he provoked her and laid there as Medb did all the only, only putting her hands on her tits and latched unto them as Medb continues to service him.
"How'd you like me now Master?" Medb asked, moaning whenever she slams herself down against his waist since their position allowed him to hit the Rider-Class Servant's G-spot which made her cry out whenever it connects. His answer to was to simply pinch her nipples to show that he is loving it which made her proud and continued to bounce on him, the bed creaking a bit.
And her efforts were rewarded when she slams herself for the final time before arching her back and crying out as she came once again, squirting all over the bed. Randall would join her as his cock bursts with more hot cum. This time, cum was leaking from her as it can no longer hold it in, trickling down from her pussy down to his waist. Once the last load was put in the Celtic Queen, Randall's cock deflated inside.
Medb panted as she came down from her high. She glances down and watch cum leak from her pussy in awe and wondered how much did her Master put in her and feeling her mana go up. Neither moved from their position, busy basking in the afterglow of their intense moment
"..... can we stay like this for a while? I can't move my legs." Medb admitted sheepishly, feeling the numbness on her lower part. Randall chuckled and allowed Medb to sit on his cock until she could get off.
