The kiss just happened. Rose and Jared probably didn't plan it at all. Especially Jared, who thinks that Rose is too different. Even so, Jared couldn't hold himself back, and everything happened according to plan.
Rose kissed him back as much as he did. Their tongues collided for dominance, and Jared won. He could not handle his desire anymore.
"oh fuck, you are so beautiful", he kept kissing and biting her earlobe. . His hand went to her thigh and kept going up and ... what is this?
"Ah, you naughty girl, you're only wearing panties, huh!" Jared growled, but half squeezed Rose's in exasperation. And Rose giggled loudly, but Jared kept kissing her neck.
