Just tease him !

When you and your boyfriend are sitting some where and has already gotten things goin, whisper to him, what ever you,re in the mood of saying. Give him a sexy smile, he will get turned on and he will want more of you ! As he is sitting down, get ontop of him, and start teasing him. Peck a small fast kiss on his lips, do it about 3 times, and he will be getting angry (in a good way). Again make like your gonna kiss him but gently tug the back of his hair and kiss his neck and make your way up to his lips. He will be so turned on, that you will have the most passionest kiss ever ! have fun :)
