His actions are too much for you. You give in.

His kisses don't give you much room to hit him in a violent way, or even allow you to find an exit route away from his sensual attacks. With no possible way out, you might as well give in to his desires. You stop trying to retaliate or to escape and in no time his pressuring kisses die down a bit. You think in your head why is he doing this to you?

Is he trying to make the scene more interesting? How interesting or dramatic can the situation be, but it does make sense.

Is he trying to say that you need to relax? This reason makes sense, in a unusual kind of way.

For all you know, he could be doing it for all kinds of reasons.
