Nightmare P.O.V

I sit there, staring at the blueprints. Cross isn't with me so that means I should be able to work right? Well, apparently not. I haven't seen him all day and I'm getting worried. I should be happy that he's not annoying me, but I honestly love him. My pride just won't allow him to know. I get up and leave my room in the castle. Tweedle Dee and and Tweedle Dumb are sitting in the living room.

"Hey Dust, Horror, have either of you guys seen Cross?" They look over their shoulder at me.

"Why would you care where he is?" Dust asks.

"Because I feel like it. Why do you want to know?"

"Because I'm bored." Dust answers, looking back to the tv.

"He's in his room."

"Thanks, Horror." I leave them and begin to make my way to Cross' room. I hear small noises coming from the other side. I open the door and look in. Cross is holding his member as he bites a pillow, trying to muffle his moans. His mouth lets go of the pillow every once in awhile to let out a louder moan.

"S-senpai!" He moans louder. I feel myself get harder at his moans. I slowly walk to his bed, quietly sitting down. I let my tentacles wonder his body, picking him up and putting him on my lap in the process. His eyes shoot open.

"S-senpai w-what a-are y-you d-do- Aagh!" He moans as I begin to lick his neck, one of my tentacles stroking his member. He leans his head back, moaning.

"Wow Cross, you look hot like this. Maybe I should do it more often." I whisper seductively in his ear. His member gets harder at my voice. I reach my hand under his shirt and grab his soul. It was a white soul with black swirling around it. Cross looks at it then back into me, worry evident in his eyes. I smile and run a finger over the smooth surface, his back arching into me. I bring it up to my face, giving it a rough lick. He lets out a long moan, turning me on even more. My tentacles begin to roam his body, covering him in the black goo. I squeeze his soul as he's now a moaning mess. His soul lets out a black substance as he moans loudly. I drink it up, sucking on the soul a bit. This earns an immediate reaction from him. After a few more seconds, he comes on my tentacle. I lay him on the bed, towering over the peace of beauty. I lick all of the cum off of the tentacle, savoring the taste.

"You taste so good Crossy. I want more." I lean in, kissing him roughly. He's surprised at first but soon melts into the kiss. I pull away and look down, seeing an entrance formed.

"Are you that excited?" I ask, running a finger over the folds. Cross shudders, bucking his hips slightly.

"P-please I-I-I need t-this."

"Ah ah ah, patience is key love." I lean down, thrusting a tongue in his entrance.

Cross P.O.V

"AAAHH!" I moan loudly. God this is heaven! He continues to eat me out as I moan. I soon come again and he drinks it up. He sits up, placing the tip of his member at my entrance. He pushes in fully, waiting for me to adjust. I buck my hips telling him to move. He takes it out until only the tip is in and slams his whole length in. I throw my head back in pleasure as he continues ramming into me mercilessly. I lose my train of thought as he pounds into my entrance. I feel close to cumming, a knot building up in my stomach.

"S-Senpai I-I'm g-gonna-Aaaagghh!" I scream as he hits my g-spot, the knot in my stomach snapping in half. I cum, but he's still going, driving me crazy. I feel his tentacles roam my body once more, rubbing all the sensitive spots on my back and ribs. I feel him swell up inside me.

"I'm gonna cum." Nightmare says. I feel close to my second release.

"C-cum inside!" I scream/moaned. I feel him ram into my g-spot, cumming deep inside. I moan loudly and cum again. Nightmare stops to catch his breath, placing a kiss on my lips.

"I love Cross. I've always had." My face lights up with joy as I hug him.

"I love you too Senpai." Nightmare chuckles.

"Call me Nightmare, okay?" I nod.

"Okay Nightmare." He smiles.

"Now I just have one more question." I look at him, confused,

"What is it?" He thrusts his hips, making me moan.

"You ready for round two?" I spread my legs wider, looking into his eyes.

"Give it to me daddy."
