Geno x Reaper

Reaper's P. O. V

I sit in my chair humming doing papers. I get them printed off then head to Geno's class. I open the door smiling.   "hello" Geno says looking down at something on his desk.  "Hello Geno" I say sweetly he looks over to me.  He blushes immediately.  I walk over putting the papers on his desk then sit in his lap.  "I want attention" I say "R-r-reap" he says stutter.  I lean my head on his chest.  "Um work I um" he stumbles over his words. I move one of his hands up my dress a bit making him blush more. I hear laughing from the students.  "Reaper later I'm busy" he says. I pull him down kissing him.  Geno kisses back sliding his hand up further my dress I gasps letting him slide his tongue into my mouth. Our tongues dance together until he starts exploding my mouth.  I hold him close softly moaning into into his mouth.  "Dad can you take mom to his office instead of doing this in front of us" I hear Goth say.  Geno breaks the kiss a string if saliva connects us that he breaks.  "Sorry got carried away" he says. I blush burying my face into his chest. "Get back to work babe" he says but I don't move I stay in his lap. Geno sighs going back to his work while I slowly fall fall asleep in his lap. I wake a bit minutes later  and decide i should let him work in peace so I kiss his cheek quickly then head back to my office where I just sit there because I finished my work a while ago.

It's been a few days and Geno has been busy so busy he hasn't kissed me me or even really had come to bed.  I sit in mine and Geno's room.  "Geno" I whine. This is just like high school all over again.  I then get an Idea. I head to Geno's office he's still working.  "Reaper I'm busy" he says I roll my eyes locking the door. I walk over hugging him from behind.  I kiss his neck then pull him out a bit.  "Reaper" he says.  "Keep working" I say getting on my knees under the desk.  I pull out his dick then start licking it.

Geno's P. O. V

I've been grading papers and working on new assignments for the last few days Reaper was getting really needy.  I want him I do I just have so much work. So he came in here and gives my dick little kitten licks.  I let out soft moans while still working.  He soon takes my dick into his mouth sucking lightly. "Reaper so good" I moan out. Reaper let's out soft moans around my dick. I place one hand on his head.  "Take me deeper cupcake" I say making Reaper take me all the way in.  Sucking more.  I moan louder loving  how it feels.  Reaper stops getting up. "What's wrong cupcake" I ask.  He blushes pulling off his pants and boxers getting on my lap sliding me into him.  We both moan softly.  "Keep  working" he says I nod kissing his neck gently.  Reaper starts bounceing up and down on my dick moaning more. I finish a paper going onto the next while Reaper wraps his arms around my neck going faster and deeper. "Nya mmm ah so good Geno you are so big and thick" Reaper says.  Something in me snaps.  I slam him onto my desk and start thrusting in and out of him roughly. Reap digs his nails into me moaning softly. I bite his shoulder thrusting into his prostate.  I moan into his shoulder.  I feel him tighten around me and cums. "Geno" he moans out.  I thrust a few more times cumming deep inside of him. I pull out then notice Reaper fell asleep.  I smile picking him up.  I lay him on the couch I have in the office.  I dress him then put a blanket over him. I look at my desk then back at Reaper.  I smile getting on the couch cuddling him slowly falling asleep.

The next day at school Reaper comes running in and tackle hugs me to the ground.  "Woah cupcake" I say hugging him softly. The class laughs at us on the ground.  I roll my eyes sitting up.  "Reap I'm busy but if you want to wait sit at my desk until everyone knows what their doing" I say.  Reaper nods sitting on top of my desk. I smile handing out the work.  Reaper sits on my desk waiting and waiting.  I finally go over to him picking him up.  Reaper giggles cutely.  "Gen Gen we should go on a date soon you've been so busy lately and we haven't really done anything in a while so let's go on a date after school ok baby" he says.  I sigh "I'm sorry I've been so busy cupcake" I say kissing his cheek. "And also I know you don't remember but its our anniversary you know because we are engaged" Reap says.  "I'm sorry love we will do after school" I say holding him close I hear Goth Palette and Cray giggle I smile to myself.  Reaper leaves then I go into the hallway making some calls and cashing in favors.  After school I go to Reaper who is now wearing a different outfit from his work one.  He looks so cute.  I take his hand leading him to the limo that is waiting for us.  Nightmare opens the door winking at me.  I let Reaper go in first then I go in Nightmare closes the door.  Reaper sits in my lap laying his head on my chest.  I hold him close and start kissing his neck Reaper moans softly as I do.  I leave a few hickeys on him on our way to a special place. we get to a place a clearing in the forest where there is a water fall also set up is a table with food and wine.  I lead him to the table pulling the chair out and pushing it in once he sits.  "call me when you need to be picked up" Nightmare says driving off.  I sit in my chair Reaper is blushing darkly.  "Geno" he says.  "Yes love" I say pouring the wine.  "You did all this after I left didn't you" he says.  "Yep only the best for my sweet cupcake" I say he blushes more. "You are such a romantic" he says.  I smile and feed him.  We eat peacefully listening to the found of the waterfall and wind blowing though the trees.  Once we are finished eating and drinking I take him to a blanket and lay down looking at the stars.  Reaper lays on me smiling. "Hey sweetie what do you think if I wore a wedding dress when we get married" Reaper asks in his sweet voice. "I'd love you in anything my love" I say kissing his head.  "Guess we will see" he says.  I nod holding him even closer.  "Happy anniversary" I say.  "Ya happy anniversary my love" he says.  "Oh I almost forgot I have a gift for you" he says sitting up then hands me a small box I open it.  Inside is a chain along with a little keychain charm.  I look at it and my name is in it.  I sit up and kiss him.  Reaper kisses back wrapping his arms around my neck. I break the kiss smiling.  "Thank you cupcake" I say.
