Two German boys have sex in the ruins

This may be a Dutch film, or maybe a German one prepared for the Dutch market. Although 'einde' end at the conclusion is Dutch the setting doesn't look Dutch, but maybe it is with all those sunflowers, but then you get Russian porn in fields of sunflowers.

I like the premise of this little film where a boy is strolling through nature and comes across a boy on a blanket having a good old fondle with himself. Neither the boy finds the other off putting. The nature boy starts stripping off and offers his cock to the boy on the blanket. They get down to some increasingly adventurous sex as they get naked and provide fellatio to each other precariously on top of ruined castle. They eventually take it indoors where they are much more comfortable in bed.

Compared to other vintage porn this one is pretty ordinary except that the two boys, particularly the shaven headed one are very attractive.
