Cross X Blue

Blue's P. O. V

"I'm breaking up with you" Fell says. I feel my world shatter as he says those words. "but I thought you loved me" I say as tears start falling. "I thought I loved you as well but then I realized you were using me to cover up your feelings for someone else" he says looking away. "plus I like someone else. Throw out the ring or sell it for all I care" Fell says walking away

I sit in my room not moving off my bed. Fell moved out and is now dating a student from the school. It's been a month but it still hurts. I loved him with all my heart we were gonna get married then this happened. "Blue... Hey you ok" Cross asks coming over to me. Ink must of asked Cross to check on me since I haven't been to the school for a while. "fine" I mumble as more tears fall. I hate myself for being like this

Cross takes me to his house into his room. "you can stay here for a while you need someone right now" he says I just nod slowly.

After a month I slowly get over Fell but I started falling for my best friend's son. Cross comes over to me giving me food. "here eat up" Cross says. I thank him eating. Cross hugs me making me smile a little. After I finish Cross takes the plate setting it aside. "Barry why did Fell break up with you" Cross asks holding my hand. "he said I was using him to hide the fact I like someone else" I say looking down "and I'm starting to understand what he meant" I whisper the last part Cross nods.

After that day I start going to school again being the nurse it's really nice being back. Cross keeps checking on me everyday making sure I'm ok. I keep stuttering like an idiot in front of him though.

"Hey Blue how are you feeling today" Cross asks walking in. I blush lightly looking down "I-I'm ok" I stutter out. Cross comes over making me look at him. I noticed you have been acting differently around me lately what's wrong" he asks. I blush more. He's younger then me but way more taller then me. "n-nothing" I reply. "Cross come on you are suppose to hang out with Dream and I" Nightmare says. Cross looks over. "ya Night I'm coming" Cross says walking out. I sigh. "I'm an idiot he's dating Dream and Nightmare" I mutter to myself

After school that day Cross comes to pick me up. "ready to go" Cross asks I nod getting up. Cross smiles taking my hand then runs out pulling me with him. We end up at a park. Cross let's go of my hand and runs off soon coming back with two ice-creams giving me one. "thank you" I say picking it

Cross's P. O. V

I smile watching Blue. He's actually really cute. I smile watching as Blue ears his ice-cream happily. I slowly eat mine. Once down we walk around for a while. I hold his hand as we walk. "so how is Nightmare and Dream" Blue asks "ok" I reply. Blue just nods. After a while we start heading back. Once in my room I push Blue to the wall kissing him gently. Blue blushes darkly slowly kissing back wrapping his arms around my neck kissing back gently. I slowly pull off his shirt well try to but Blue stops me breaking the kiss. "aren't you dating Nightmare and Dream" he says. "no I'm not they are just friends" I say kissing him again removing his shirt. I run a hand down his body making him gasp. I slide my tongue in his mouth

Blue moans softly into my mouth making me want him more. We make out for a bit then I break the kiss hoi g down to his neck kissing it sucking and biting at it leaving marks on him. I smile looking at his neck then I strip us both until I push him on my bed looking at his naked body. I lick my lips getting on top of him. I make him lick my fingers.

After a bit I pull my fingers out of his mouth then push a finger into him making Blue moan. I kiss his head adding another finger then start fingering him Blue moans louder loving it. I soon pull my fingers out then slowly push into him. Blue moans holding onto me. I start thrusting in and out of him slowly loving the feeling. "more Cross please" Blue moans out. I thrust faster harder and deeper making Blue moan louder. I groan as Blue moans feeling so good. After a bit we both cum. I slowly pull out laying next to him. Blue cuddles to we. I smile pulling the blanket over us. We fall asleep.

When I wake up mom is standing by my door. "so you slept with my best friend" mom says I blush a bit. "he's cute and I like him" I answer. "whatever just don't hurt him and don't get hurt sweetie" mom says kissing my head then walks out closing the door.

Blue wakes up a while later looking up at me. I smile a little kissing his head. Blue smiles kissing me gently I kiss back holding him close.

Few months later

I hold Blue's hand walking on the beach at night. I kiss his hand smiling a little. After a while I stop then face him Blue I love you" I say smiling he smiles "I love you two" he says I look into his eyes. "I have loved you for a very long time" I say getting one one knee pulling out a ring. "so that's why I want to marry you" I say. Blue hugs me smiling. "of course I'll marry you" he says. I smile hugging back then put the ring on him. I'll never leave him like Fell did. I kiss Berry smiling. Blue kisses back happily.

More months later

"I can't believe you two actually got married" mom says. "I wasn't expecting it either Inky" Blue says cuddling into my side as I have an arm around him. "So my best friend is now my son in law just still need to get use to it" mom says. "yep and he's pregnant" I say smiling kissing Blueberries neck lightly.
