Sebastian pulled Grell's swimming trunks back up and smiled. "You should've brought underwear." he said, even though he had forgotten it himself too. He grabbed Grell's shirt and gave it to Grell. "..Or do you need help with that?" Sebastian asked and kissed Grell's neck. Grell giggled and tangled Sebastian's hair. "No, I'll be fine dressing myself. It's just undressing myself I need help with." Grell said. He closed his eyes for a second and enjoyed the feeling of Sebastian's breath on his shoulder. "Good." Sebastian said. "We should go swim more often, mister Grell." he said while he put on his shirt and shoes. "We definitely should, Sebas-chan." Grell answered. Just before Grell opened the door of the changing room, Sebastian pushed him against the wall. Grell gazed into Sebastian's red eyes and blinked. Sebastian moved the hair which was in front of Grell's ear. "Ai shi teru." he whispered. "Watashi mo daisuki." Grell said with a smile. Sebastian slowly pushed his lips against Grell's, moving his hand through Grell's hair. Grell wrapped his arms around Sebastian's neck as they kissed.
Sebastian had always had some kind of weakness for the reaper and since he had the oppertunity to take all Grell he needed, he made sure to get all of it and keep it forever. He placed his hand on Grell's cheek while his tongue moved through Grell's entire mouth. Grell played with Sebastian's tongue until Sebastian pulled back.
"We should get to the coach now." he said. "Young master is waiting." Grell nodded and followed Sebastian to the coach. He climbed in and smiled at Sebastian. The coach started to move forward when Sebastian closed the door. "Sebastian.. What happened to your hair." Ciel asked. Sebastian's cheeks turned slightly red and he immediately started to fix it. "Sebas-chan, let me help you." Grell said. He ran his hand through Sebastian's hair and carefully moved it back into it's usual form. "This will do, I guess." Grell said with a smile. "Now, how did your hair get ruined again...?" Ciel asked again. Sebastian sighed. "You don't need to know everything, my lord." he said and smiled. "...That means it must've been something disgusting, mustn't it?" Ciel asked with a develish smile, which disappeared right away when he started to think of all the things that could have happened. "Never mind, Sebastian, don't tell me." he muttered.
As soon as they arrived at the manor they got out of the coach and went inside, except Grell. "Why don't you come in, Grell?" Sebastian asked slightly worried. Grell smiled. "Well, I think I'll just go home. It was fun, I've had a great time with you, Sebby-darling." he said and winked. "But I'll see you tomorrow, probably." "Let me at least bring you home. You must be tired of... Swimming." Sebastian said with a grin. "You don't.." "Young master, I'm bringing mister Grell to his house!" Sebastian yelled before Grell could finish his sentence. Grell rolled his eyes. "This isn't necessairy, I'll be home in a second." Grell muttered as Sebastian grabbed Grell's hand. "It's very necessairy, mister Grell." Sebastian said while he walked home with Grell.
Grell gave Sebastian a kiss when they arrived at his house. "Thank you for today." he said with a smile. Sebastian shook his head. "Today isn't over yet." he said smiling and pushed his lips against Grell's to roughly kiss him. "Sebastian!" Grell screamed because of the shock, but kissed Sebastian back right after. Sebastian pushed Grell inside his house and closed the door by kicking it. Grell threw the keys on the kitchentable as he fell on the ground because of Sebastian. Sebastian slowly pulled back. He looked at the reaper he was sitting on and smiled. He bent forward and started to slowly unbutton Grell's blouse, without breaking the eyecontact. Grell swallowed, he never expected things like this to ever happen. He had loved Sebastian since he met him, but never tought of the fact Sebastian would ever love him back. He never tought Sebastian and he would end up like this. Kissing on the floor, stripping each other naked. Grell grabbed Sebastian's hand, bit in the cloth of his glove and slid the glove off Sebastian's hand. Sebastian grinned and stuck his other hand to Grell, who did the same as with the other glove. Sebastian pulled off Grell's blouse as he finished unbuttoning it and tenderly sucked Grell's nipple. Grell moved his hand through Sebastian's hair and tried not to moan, but couldn't stop a small moan coming from between his lips. Sebastian chuckled and started to kiss Grell's chest, slowly moving down to Grell's swimming trunks which he was still wearing. "I'll have to remove these again." he said smiling and pulled them down. Grell gasped as Sebastian released his growing member. Grell rolled on Sebastian, which made them switch positions. He unbuttoned Sebastian's blouse as as fast as he could and accidentally pulled off a few buttons. "You aren't very careful when you want it, are you?" Sebastian asked with a grin. Grell smiled lustful which was enough of an answer to Sebastian. He took off Sebastian's shirt and swimming trunks. Sebastian pushed Grell in the ground. "Sebby..." Grell gasped. "Not on the ground." he muttered and crawled to the couch. Sebastian chuckled and followed Grell to the couch, without looking tired at all. "Grell, I love you." he whispered before he entered Grell with two fingers. Grell moaned and sighed when Sebastian added a third finger. "I love you too, Sebas-chan." Grell gasped. When Grell said that Sebastian removed his fingers and replaced it by something bigger, looking for Grell's spot which would make him scream. "Sebastian! It hurts!" Grell screamed and even though it hurt, he enjoyed the feeling. Sebastian came inside of Grell and slowly removed himself out of Grell. He gasped, just as Grell and gave Grell a short kiss on his cheek. "Do you want something to drink, Sebby-darling?" Grell asked. "No, I must return to my young lord. I'm sorry, I'd love to but I don't have time." Sebastian muttered a little bit sad. "It's okay, maybe another time." Grell said with a smile. Sebastian dressed himself and gave Grell another short kiss. "You're fun, mr. Grell." he said again. Grell giggled. "You too, Sebas-chan. You too."
