The boy and a girl his age sneak up a hayloft and watch the teen girl have sex with a man, afterwards the little girl makes fun of it by emulating the sounds and rubs herself all over.
The boy has a 'wet dream', where he's a knight rescuing the teen girl, who's been tied up with tarnished clothes and her breasts exposed. As the boy unties her and starts to hug her semi-naked body, he wakes up. Realising he's had a wet dream he punishes himself by slapping his penis with a wet towel.
A boy (Pétur Björn Jónsson, 9) coerces a younger girl (Steinunn Þórhallsdóttir, 7) to play 'show-me' (in exchange for trying his bike). They then go to a recluted place, where the girl pulls down her panties (seen from behind, obscured by her skirt) and lifts up the front of her skirt, showing the boy 'her privates'.
This same girl is later lying on top of a haystack, alongside the boy from scene 1, when she suddenly sits up & plants a quick kiss right on the boy's lips (with a comment about what a lousy kisser he is!). The boy quickly retorts by kissing her back in the same manner (adding a comment back that it's sure better than shoving her tongue down his throat like she does!).
