Joint Penetration by Katherine McIntyre

Liam Kelly is in love with his best friend. His straight, freshly divorced best friend, who wants to experiment…with him.
Ollie
The last thing I expected from my wife was a divorce. I’d checked all the boxes off—cozy house near my folks, joined the family business as a contractor, and married right out of high school. Except the more I think about how distant we’ve been, the more our split makes sense. And the more time I spend blowing off steam with my best friend, the more I want to actually…blow him.

Have I been hopelessly in love with Ollie my entire life? Yes, yes, I have. Has he been married for the past decade? Yes, yes, he has. However, when his wife calls it quits, my heart can’t help contriving scenarios where he might not be as straight as he seems. And when those scenarios start coming true—from scorching looks to playful grapples until we go much further—I throw myself into the deep end.
The second we start hooking up, I can’t hold back the feelings I’ve been clutching tight to for over a decade. But if this ends up a rebound for Ollie, a blip before he looks for a new wife, I won’t only be out a best friend but the love of my life.
