Some Like It Spicy by Linda Verji

When two strangers, Xolani Moore and Barry Hale, meet on an airplane, sparks fly. They’re each other’s fantasy come to life. However, they’ve both been burnt by love before, and they decide that they’re better as friends.\
But their chemistry is undeniable!
What follows is an ambiguous game of friendship and flirting that tests the limits of their self-control. Soon, they’re in too deep. Their supposedly platonic relationship has snowballed into something steamier… something lustful. Friendship isn’t enough for them anymore.
They want… no, they need more.

This could end with a happily-ever-after. Or it could be a recipe for complete disaster.
