Melt Like Butter by Daisy May

Work, eat, call Mom, repeat. Andy’s comfortable routine is shattered when a stranger comes to his door, claiming he’s looking for his biological mother. Angry and suspicious, Andy makes it clear that he never wants to see Tyler again.
When Andy finds out Tyler was telling the truth, he reaches out to him again. But Tyler isn’t quite what he seems. As Andy realizes Tyler is a man with secrets, he finds himself determined to unearth them. He doesn’t know why, but he can’t leave Tyler alone. Helping him with his search turns to an odd sort of friendship – and a powerful attraction that neither can deny.
Butter wouldn’t melt in Tyler’s mouth. What will happen when he’s the one melting for Andy?
