[I]I knew him many years since. My brother had given him maths classes. Beside of this, our families had gone together for vacations to the seaside, so he had an idea how well I looked in a bikini (I used to be a tennis player).

I may be wrong, but I do feel that perhaps in your subconsious you enjoyed the boy seeing you in your underwear!
The fact that his mother didn't choose or did not think to send him out of the room is not really relevant.
Even turning and walking out of the room was not really a mistake! You knew you had a nice bottom so why not show it (even if you did so unintentionally).
Yes, some of the other comments are right! This young boy will have had many a jerk-off at your expence. Am I wrong in suspecting that you too may have thought about this when remembering the incident?
What a shame though that no photograph exists of this incident, I can only image the look on your face when you realised her son was with her
