What happens in the last part of the first day's hunt?

At the end of the first day's hunt, the lord's hunting party returns with a great number of deer by sunset, as promised.  and they then begin the meticulous process of cutting and dividing the bodies of the game. Once this is done, they return home and Gawain commends the lord for his fine hunting. As promised, the lord gives the game to Gawain and Gawain, in exchange, gives the lord a sweet kiss he received that day, but refuses to reveal who it was won from, claiming that it was not part of the agreement. The two men revel for the rest of the evening and agree to continue their contract, by exchanging their winnings of the next day.
