[Denpashishi (Ichishiki)] Thank You Youngest! Volume 1 (Osomatsu-san)

Todomatsu, the spoiled youngest of the Matsuno brothers, squeezes into a cheerleader's crop top and pleated skirt to rally his older siblings—and they plan to show their gratitude in the most hands-on way possible. Karamatsu grins off every plea to wrap it up, insisting 'it's best to make love naturally' as he takes the youngest bare, while a stunned 'you're gonna live here?!' tangles the household into breathless cohabitation chaos. When Jyuushimatsu and the rest line up to collect their 'fee' from the crossdressed boy's plump, upturned ass, each brother finds his own filthy way to say thank you.
