While Victoria wasn't as good at moving her hips as the other wives, Andrew was enjoying her tight, hot pussy. Andrew's cock moved in and out in rhythm with the movement of Victoria's hips.
We must remember that this world is quite limited in terms of sexual imagination. Although there are pleasure houses and many other entertainments for adults, they are not very varied.
Even for sexually experienced women like Helena, most are limited to simple positions like missionary. In fact, these women have become so experts and experience different things thanks to Andrew's influence.
It is for this reason that Victoria, despite having a good experience in bed, was not very good in a Cowgirl position, since she only began to experience it recently at the Dunnas Palace, thanks to the fact that the courtiers of the place were taught by Sonia, who in turn was trained by Andrew.
