みのりん「手が冷たいの？　じゃあ、はい♪」　ずぼ　「穣子さまの谷間あったけぇぇぇぇええええぇぇ！」　みたいなのを描きたくなったのでひとつ☆　んもー手が冷たくてやってられませんね冬は！誰か谷間貸してください！　個人的に穣子さまの谷間ってあったかそうだと思いました！きっと焼き芋も作れますよ！

Someone please translate this.

Minorin "Is your hand cold? Okay, here♪" *slip* "Minoriko-sama, your cleavage is so waaaaaaaaaarm!" was the sort of the thing I wanted to draw, so here's one☆ Oh, geez, I can't stand how cold my hands get in winter! Someone please lend me her cleavage! I personally think that Minoriko-sama's cleavage looks warm! She'd definitely roast sweet potatoes for me!

From the thumbnail I thought it was one of those sushi roll puns.
