kissing during fasting hours

1st i must point out that im not thinking of doin this myself lol, but would it break ur fast if you kiss your partner? just something that i have been wondering!!!

There's a hadith that shows the permissibility of Kissing/foreplay between spouses during Ramadhaan, here it is:

Aa'ishah said: "The Messenger Salallaahu 'alayhi wasallam used to kiss (his wife) while he was fasting, and he used to involve in foreplay while fasting, but he was the most able of you to hold back his desires.
[Bukhaaree and Muslim]

Hope it helps.
