Berserker x Shirou lemon

A/N: I do believe this is the first ever Berserker (Frankenstein's Monster) x Shirou lemon on the Internet. I hope I do this pairing and sex scene justice with my humble writing skills. Also I grabbed as naked of a picture as I could off Type Moon's wiki. I didn't like the swimsuit ones from Grand Order where she's Saber but I did like this one on the bed a lot. I wished it showed a little more of the front side but hopefully the picture can give you an idea of what I'm trying to go for in my description of her.

You and Berserker appear in a lavish bedroom. Both of your clothes have been summarily discarded during the process. You must certainly still be in Caster's temple somewhere, as you can still hear Rin's shouting. But none of that matters compared to the striking, raw, primal beauty of Berserker's naked form. She is a lithe, tall, thin girl with barely B cup breasts and small ass, and she sits in your lap with the tip your erect cock against her flat stomach. You feel the heat emanating from her core.

Berserker smiles as she silently shifts her hips, rubbing her hot, wet snatch against the length of your steel-hard member. She lets out a grunt as you pierce her maidenhead. While she rests for a minute, she grabs your hands and smiles. She places them gently on the metal fins that just out of her neck and utters, "Traaace...."

She kisses you softly and takes the lead, slowly riding your clock. You feel both a spark of electricity and her mana pushing into you from the place where you're connected. You return her attention and do as she asks. "Trace, on." You whisper and complete a full circuit with Berserker's and your energy. It's a closer and more intimate connection than you've ever had to anyone.

"Shirou.. " Berserker whispers. "Thank you..." You feel Berserker increase the pace of the intimate fucking as she grips you tightly with her arms and legs. Her pussy naturally squeezes around your hard dick as well as she slides or in and out of her slick hole.

"I give you everything that I am." She whispers. You feel the fins under your hands rotate and open. She fully hilts herself upon you and you both smile as she leans her metal forehead plate against your own head. She whispers the words which pierce your very being and cause the mixture of her and your energy to flow up the length of your cock, through your spine and deep into the hot iron spike of your Trace. "Release limiters. Galvanize."

The energy pours out of your hands and into Berserker's metal fins. You kiss and the energy flows freely into her waiting mouth. You're hands subconsciously grip Berserker harder as lightning itself enters your spine through your intense fucking. You blast your first load into Berserker's hot core, further fueling the intense reaction that's already outfitting between you two.

You feel your hands release from Berserker's metal fins and nice down to grab her ass, pumping your your hot cum further inside Berserker. Both of you are impossibly and fully connected with each other. You lay Berserker down and take her in the missionary position. With the intense feeling of being one with her, it's not long until you fill her up once again and Berserker bequeaths you with her ultimate gift: Blasting Tree.
