Andrew Robertson is a twink. He was 18 at the time of filming. Towards the beginning of the movie and again after, he is jerking off in front of the mirror but we cannot see much. He looks very young and does not even seem to have armpit hair! One night it's raining and we see Andrew Robertson getting naked and walking naked in the rain. Although it's dark, we get a good view of his big uncut dick and firm butt. We see him naked again a few minutes after that, rear and front, when he gets naked into his brother's crib! He finally makes love with his sister Charlotte Gainsbourg but we don't see too much from Andrew there.
