Headcanon #5

The first time Bertholdt called him fluffy, Reiner looked majorly offended. Not a second later he was snarling, pointing out he was made out of hard muscles - verdammt. When he removed his shirt and flashed Bertholdt his hard abs and firm pecs, not to mention his killer guns, Bertholdt could only admire him and apologize dazedly as he resumed caressing the other’s hairy arms up to his collar bone and down the patch of hair that thinned out near the waistband of his trousers. After that, even murmuring the word fluffy had Reiner naked to prove him wrong - Bertholdt simply used the commando to sate himself.
