"Exactly six months!" Grell ran over to Sebastian, skipping and singing. "it's been exactly six months since our first kiss! What do you-" he was cut off by Sebastian's lips on his.
"You've been keeping track?" He asked.
"Of course, Sebby-chan! Why would I not? And by the way, that was our four-hundred and thirty-fourth kiss." Grell said as he smiled up at the dark-haired demon.
"Your keepi" Sebastian asked.
"Oh, I have an internal memory for things like that." Grell said coyly. He grabbed his hand and pulled him to their room.
"I was hoping we could do something special for our anniversary." He explained. Sebastian pushed him up against the wall and started kissing up and down Grell's neck.
"Ah….Sebby…" Grell moaned. He started unbuttoning Sebastian's tailcoat. Sebastian had Grell's jacket and vest off before they broke apart. Grell sat on the bed and pulled Sebastian on top of him. Grell got Sebastian's tailcoat off and threw it across the room. While Sebastian started on his shirt, Grell removed Sebastian's tie and vest with his teeth. He managed to get Sebastian's shirt off and eyed the demon's muscular chest hungrily. Sebastian smirked and very slowly unbuttoned his pants and inched them down.
"Sebas-chan, don't tease!" Grell pouted. He grabbed the hem of Sebastian's pants and pulled them down, along with his boxers.
"Oh…oh my…" Grell said, eyeing Sebastian's enormous erection. Sebastian smirked again.
"Like what you see?" He asked.
"Not just what I see..." Grell took Sebastian's shaft in his hand and started rubbing it. "Feels nice too."
"Ohh…." Sebastian moaned.
"Wonder how it tastes…" Grell licked up the side of Sebastian's raging hard-on. Sebastian bucked his hips upward.
"Mmmmmm, I think I need to do some further research on the taste…" Grell put his tongue on the head of Sebastian's member and swirled it around. Sebastian moaned sexily.
"Do you want more, or are you afraid of me biting you?" Grell asked. He lifted his head up.
"I trust you…." Sebastian said.
"I was hoping you'd say that." Grell took Sebastian's member in his mouth and started sucking. Sebastian arched his back. Grell took him deeper, so that he hit the back of the reaper's throat. After a few minutes, Grell took his mouth off but still massaged Sebastian.
"Are you close yet?" He asked the demon.
"Ahhhh….yes…." Sebastian answered. Grell put his head back down and sucked faster.
"Grell…..!" Sebastian said. Grell swallowed and licked his lips as he sat up and shed the rest of his clothes.
"Damm, your good..." Sebastian said.
"ah...I d-do try." Grell replied coyly as Sebastian lightly fingered his slightly-smaller erection. The reaper melted instantly. Sebastian took Grell's member in his mouth and slowly started sucking.
"Ahhhh, Sebby-chan….faster…please!" Grell said. Sebastian's eyes lit up and he lifted his head up.
"How mad would you be if I stopped?" He asked.
"I would kill you and send you back to Hell…." Grell said.
"Well, we wouldn't want that." Sebastian put Grell back in his mouth and used much more tongue to make up for the lost time.
"You…..b-better…not….do…that…again…"Grell said, barley able to form a complete sentence.
"Don't worry, I won't." Sebastian said. They went on like that for a few more minutes.
"Sebby, I'm…..!" Grell cried. Sebastian lifted his head up and licked his lips free of the few drops of cum. He kissed the reaper hard.
"Number 435" Grell said, smiling. He then took three of Sebastian's fingers in his mouth and started sucking on them. Sebastian scooted closer to Grell so that their bodies were touching. He moved his fingers around in Grell's mouth and licked the reaper's ear. Grell opened his mouth to moan and Sebastian used the opportunity to take his fingers out and kiss the unsuspecting red-head hard.
"436." they both said at the same time. Grell laughed then tensened as Sebastian spread his legs.
"Ready?" Sebastian asked. Grell nodded.
"R-Ready" he said. Sebastian took put one finger inside of Grell's tight hole.
"Ngh!" Grell cried out. "S-Sebby-c-chan!"
"do you want more?" the demon asked.
"ah! Yes! Yes I want more!" Grell cried. As Sebastian added a second finger, he thought about how glad he was that Ciel had moved into Alois' mansion with him. It would be very awkward trying to explain this, and trying to keep Grll quiet was a lost cause.
"S-Sebas-Ahhhh!-c-chan!" Grell screamed, as if to prove what Sebastian had been thinking. "Ahhhh, faster! Faster!"
"how about this instead?" Sebastian asked as he began to scissor.
"oh! Ah! Yes! Yes! Oh more!" Grell screamed. Sebastian happily obliged, causing the reaper to moan loudly and arch his back. Finally, Sebastian pulled his fingers out and lined up the tip of his member to Grell's hole.
"Ahhhh! Sebas-chan, please, fuck me, fuck me now!" Grell cried in anticipation.
"such naughty launguage..." Sebastian said, distracting the red-head.
"please! Please fu-Oh!" Grell begged, then gasped as Sebastian entered his huge member into Grell's hole. He started thrusting slowly.
"Nya! S-Sebby! Oh! Oh yessssss! More! Faster!" Grell was legitimary screaming in pleasure now. He met each of Sebastian's thrusts with one of his own. Sebastian grabbed the reaper's hips and thrusted harder.
"Ahhhh! Seb-Sebas-Cha-chan!" Gell screamed louder, "Sebas-C-c-chan! I'm gonna...!" A few seconds later, Sebastian came too, filling Grell to the brim and slid out. He collapsed on the bed, exsausted and pulled Grell close.
"I love you so much, Sebby." Grell said. Sebastian kissed him.
"There is no possible way for you to love me as much as I love you." he challenged.
"There is too! And that was number 437, by the way." Grell said sleepily. He snuggled into Senastian's heaving chest and smiled.
"I love you more." Sebastian said. Grell yawned.
"I'll show you how much I love you..." his eyes closed and he fell asleep.
"I told you that it was impossible to love me more than I love you." Sebastian wispered into the sleeping Grell's ear. Then he too, fell asleep.
