Most Humans are too fragile for what I would consider good love; however, since you have asked respectfully I will tell you. 

Do not fuck like you masturbate.  It has to be a full body effort and do not focus on just the genitals, but every pressure point and exogenous zone.  The skin, in it's totally, is one huge pleasure organ.  And if she's into it: don't be afraid of hurting her, she can take more than you know... And may secretly crave to be broken by a man who has proven himself worthy.  But you have to be strong: strong enough not only to overwhelm her senses but also to earn her trust that you will not lose your control.

Speaking metaphorically if your can reach into her spiritually and hold her beating heart in your hand she'll be yours forever.
