Featuring: Original character and Mysterious Heroine X
Saberface. A word that Randall was familiar with since arriving at Chaldea. It's a trait that's referring how some Heroic Spirits have faces that are identical to Artoria Pendragon from the Saber-Class. At first he thought it was an exaggeration from Romani and Da Vinci until he saw it firsthand when he summoned more Servants. Turns out they weren't lying.
He could understand Morgan le Fay and Mordred resembling Artoria, since they're her sister and son respectively, but then he discovered that Jeanne d'Arc, Nero Claudius and Okita Souji are also Saberfaces. Hell he's even managed to summon two alternate versions of Artoria like her younger self Saber Lily and even her big-tittied Lancer-Class version. Despite this, they were not offended and seemed to be fine with the running joke.
That is until he summoned Assassin-Class, the Mysterious Heroine X. She's another version of Artoria, but unlike the others, she doesn't tolerate other Sabers as it was her goal to eliminate all the other Saberfaces and become the strongest Saber in Chaldea.
Knowing she could jump at any Saberface Servant when he wasn't around, Randall struck a deal with X: In exchange for not attacking any Saberface in sight, Randall would spend twice the amount of time into increasing his bond with her so she can get stronger. The Assassin-Class was more than happy to take it since it would mean her Master would praise her more than any other Saber. Of course Randall decided not to reveal he knew her real identity due to how obvious it was.
In time X could feel she was getting stronger as she and Randall spend hours grinding materials and that fueled her pride. But like any Servant, she would inevitably ran low on mana and in need of a charge. At first X panicked and thought she would lose her Master's attention. Instead, Randall invited her to his quarters as he will perform Mana Transfer where not only will X regain her lost mana back, would but also increase her strength.
Randall's lips crashed int X's who wrapped her arms around her Master and returned the gestures as they make out standing up. The Assassin-Class was in her white and blue underwear save for her jacket which was instead zipped open and still had her hat on. His hands reached for her E-cup tits and fondled them through her bra which made her moan. In turn she grabs her Master's stiff 12-inch cock and begins jerking him off.
They continued their makeout session for a while before they brake the kiss, their faces flush with lust and need. X wasted no time discarding her underwear and turns so that her dripping wet cunt is exposed to her master. "My pussy is yours Master~" X purred, wiggling her hips to entice him. It works as X yelps when Randal gets up from behind her and rubs his eager cock against her pussy folds.
"Such a naught Servant." Randall growled, his right arm placed on her waist while using his free one to grip one of the Assassin-Class' tits. The tip of his manhood positioned and without hesitation, Randall slams into X making her scream out in pleasure as the shaft completely fills her. she had no time to savor the feeling before Randall thrusts in and out of her in a hard and fast pace.
"Ah! So rough Master! Yet if feels so good!" X squeals as Randall rams his cock into his Servant like a bull in heat. He pulled the self-proclaimed "best Saberface" back while he thrusts forward so that his cock could explore every nook and cranny due to his massive size. Sweat poured from their bodies as they got close and closer to their end.
"Cumming!" X's tight pussy proved too much for the Master to handle and Randall's cock swells inside the Assassin-Class' cunt as he spews hot cum into her. X arched her back and cried out as her needy pussy was being flooded with her Master's semen, drenching her insides white. They stayed in that position for a while until Randall's balls stopped churning and he sighed in relief as his orgasm cools down.
Not content with just one creampie though, Randal positioned X next to his bed where they are kneeling and lifted one leg while continuing to thrust into her stuff cunt. "Oh yes~! Fuck me more Master!" X moaned out as she clutched the bedsheets and cling on the edge as if to anchor herself while he hammers her. Her nipples scraped against the cotton of the bed as the blonde Servant is being railed by Chaldea's last Master.
Randall groaned as he could feel the Assassin's cunt clenching with every thrust he made, it seems she was into this for a while and you intend on satisfying her as he starts speeding up a bit. Her voice pitched a bit higher as he gradually sped up and it wasn't before X gave a long moan as her pussy squeezes the Master's cock and squirts all over his waist. Randall grits his teeth as he cums inside the Servant.
Since it was already full, X's womb pushed out the old cum followed by the newer due to overflowing semen being pumped. X's eyes rolled into her yead as she claws at the bedsheets as her Master creams her need womb. She bit her lips, bod shaking in ecstasy as Randall finishes inside her. X sighs when the orgasm ended, but gasped when she felt his still hard shaft twitch inside her, indicating she was in for another round.
Soon X was moaning as she was pinned underneath Randall in a missionary position, his hands once attached to her bouncing breasts again as he shoves his cock into her. By this point, X had heart-shaped pupils and her face flushed red as a tomato as she took her Master's massive cock. Their sweat clinging to their skin as Randall dominates his Servant. He leans down to kiss X again o which the Assassin return, their tongues clashing once more.
Eventually both Master and Servant moaned into their mouths as X's cunt clenches his cock one more time, squeezing it for its worth as she squirts. The shaft spews its final loads into the Assassin's womb, filling her up again. This time cum kept flowing out of X since there was no more room for Randall's cum to hold it in, making a stain on Randall's bed. Not he cared though as he stayed in that position before his felt his cock deflate.
"That..... was a good fucking X." Randall hummed as he slowly withdrew his limp away out of her, watching as his essence leak from her sore and filled womb in a motion similar to maple syrup. Her flushed face also added to her beauty as he marveled at the sight of the self-proclaimed "best Saberface.
"Thank you so much Master." X panted, her eyes shadowed by her baseball cap as she could feel his cum dripping from her cunt down to her asshole and into his bedsheets. She was exhausted but also recharged her mana with Randall and she would promise to repay him, right after cleaning up.
