Foreplay is basically everything you do sexually before actual penetration including kissing her sumptous body all over, petting and feeling her wanting coochie, and oral sex (licking her clit as well as massaging her whole sex organ with your tongue), designed to get that hot little number so wet, so horny, so bothered that penetration will be the easy part.
As part of a broader sexual interaction, foreplay is an essential component to your 
seductive moves which stimulates and prepares the mind, the heart (seat of motivation), the body and especially the emotions. The mind and heart is essential guys, however when you get to the touching and petting you want to make sure to seduce the emotions by doing your foreplay right. You want her luscious body to move deliberately and at your command, slowly going through the phases of her sexual response cycle in preparation for the ultimate all night penetration
(you pervert)
Touch (kino) is a key element of foreplay because the surface of the body is covered with many receptor cells (nerve endings) that transmit pleasurable sensations to the brain. Some parts of the body, particularly the clitoris , penis, nipples, fingertips, palms, lips, tongue, and soles of the feet have more densely packed nerve endings. These areas are sometimes called the erogenous zones, although, in fact, the entire surface of the skin has been referred to as the body's largest sex organ because every form of pleasure and sensation during foreplay are transmitted through the skin.
That being said, you must treat any kind of kissing, hugging, intimate touching, and related acts of physical intimacy, as important acts of your seduction strategy. Some guys also find light touching or tickling of the surface of the skin to be especially stimulating. Back rubs and massages (with or without massage oil or other artificial lubrication) are considered to be very erotic and sexual by women. In fact, one female actually said, if it wasn't for the massage she got, i would have never gotten to her ...I knew that all along...she didn't 
Others prefer more intensive hand to body caressing and exploration of the erogenous zones, commonly referred to as petting.
It is sometimes said that the human body's most erogenous zone is the mind. Foreplay, as a result, is not merely an issue of physical stimulation but also a deep intense emotional and mental stimulation that captivates the entire body all over, in effect putting her in a sexual shallow trance.
Why is foreplay so important? For one, most women need prolonged stimulation in order to reach a complete arousal, and foreplay will provide them with the required stimulation. So men who know how to cuddle and kiss their partners and know how to enjoy sensitive foreplay will often find that their partners will not only enjoy sexual intercourse more, but also see their partners reach orgasm more often.
Men who do not know how to use foreplay, or worse, play down its importance will most times find that they will start a sexual routine only to end up frustrated and upset. Why? Foreplay is what you need to use to get her hot and bothered, to get her mind on the penetration, rather that on how she's going to feel tomorrow after she sleeps with you.
Once her mind right, that is, all consumed with how good and warm its going to feel deep inside, you essentially have her body, for the body is the slave and obeys the mind. So occupy her mind - and the ass will be yours.
