SMUT DONT READ IF U DONT LIKE
After the steamy night they had they were embarrassed they never done those things before it was their first time it was the morning so they got up and got ready for another day officially together. To Shinra surprise Arthur was being overly overprotective of him he went everywhere Shinra went everyone noticed it too it was weird.
Everyone was in the room where they work when tamaki goes in and let me tell you this she always ends up tripping and having her clothes getting taken off I don't know or in fact everyone always wonders why anyway as walks in she trips and land on.... Shinra yup you guess right Shinra. Obviously he blushed a bit and Arthur well he got mad and immediately pull her away from Shinra and glared at her like he's protecting him from a killer all of them were shocked when Arthur did this. She apologized which she never does she always blames Shinra for this kind of situation but this time she knew what was going on and apologized.
Nighttime
When they got into their rooms it's was pretty quiet actually too quiet so Shinra spoke "hey Arthur are you m-mad". Arthur just stared at Shinra for a long time and said " I'm sorry I got jealous and got mad when I saw her on you I don't want anyone touching you." At that time Shinra blushed seeing him that way was cute and then Shinra kissed him while Arthur eyes widened and then started to kiss back. They were getting into the moment Arthur having his hands behind Shinra back, Shinra getting on Arthur's lap and they continue kissing. They started taking off clothes until their only in their underwear Shinra noticed Arthur's big bulge and touched it Arthur silently moaned and blushed. "Shinra w-wait *pants*" and before he says more Shinra is going down on him and taking his member Into his hand, he starts with the tip and then decides to take it in his mouth "ahhh Shinra it feels g-good" and then Arthur hears a moan from Shinra and realizes he's preparing himself with his 2 fingers "wait Shinra are we going to do it" Shinra smirked "well obviously I want my first with you and I want to be your first Arthur." After that Shinra got on top of Arthur again and put Arthur's member in his hole only taking in the tip both Shinra and Arthur flinched and closed their eyes since it's their first time it felt good for both of them. Shinra then immediately put all of it in and started to moan loudly Arthur breathing heavily and grabbing the blankets as he was feeling the pleasure being inside of Shinra. "Ahh Shinra it's hot inside of you it feels good." Shinra started to go faster "ahh Arthur it feels good I love it  you being inside me"
Both of them didn't last long both of them said something "It's gonna come out" Shinra said "INSIDE RELEASE INSIDE ME." Arthur feeling too much pleasure "Ngh mmm it feels good ahh Sh-" and both Shinra and Arthur came Shinra came on Arthur's stomach and Arthur came inside of Shinra.
It took a while for them to catch their breathing and 5 minutes before Arthur took his member out. Shinra and Arthur both looked at each other and smiled they both loved each other at this moment they were happy they were each other firsts.
