When you find yourself in Spencer’s bed, there is no time to wonder what led you there. You have no interest in debating it, either. Your attention is diverted, devoted to more pressing things—things like the feel of his hands on your hips and his lips on your neck.
You’d never even allowed yourself to wonder what instinct drove you straight into his arms… not until his mouth shifts to your ear.
“Do you want to know why you’re really here?” he asks.
You nod before you’ve even considered the question.
This was the correct answer, and he rewards you by sneaking a hand between your thighs.
“You’re here because I want you to be,” he says, “and humans are, at their core, simple animals acting on the same instinct as everything else.”
