I've decided I'm going to refer to Buff Boom Sonic as 'Boof Sonic' (Boom, Buff, Boof, get it?) moving forward as I think Buff Boom is a bit of a mouthful.
Anyway, Sonic and Jaden were feeling tired. Jaden offered to let Sonic sleep on his bed and because of how bulky Sonic is now, Jaden allowed the hulking blue monster to use all available pillows to support his head and huge shoulders. This with the condition that Jaden could use big blues arm to rest on. As you can see, it was a done deal.
Although looking at this posing makes me wonder how heavy Sonic must be and if he would actually be crushing Jaden in real life. I mean just look at those blue thighs, there about the size of Jadens own torso. o_O
Also, I made an animation on Boof Sonic recently which, if the this link works, means its already published :D https://youtu.be/VH7kPWABx1M
