C is for Comfort (The Alphabet of Desire #3)
Colette Davison

C is for Comfort is the story of two men learning that life is about more than work and that cuddling can fix everything. It's the third of three steamy, low angst novels, which follow each of the ABC triplets as they find love. You can read Archie and Blake's stories in A is for Aftercare and B is for Beg.
An age-gap M/M romance.
