Does anyone know what manga this came from?

I think it's from Nikushoku Danshi to Soshoku Danshi. I wish scanlation groups would let us know from what manga the images they use are, don't you agree? So many times I've seen interesting looking images but I wouldn't know what manga they are from so I couldn't find them to read them
