The Milan court that convicted Silvio Berlusconi of paying an underage prostitute for sex at his infamous Bunga Bunga parties says in remarkably raunchy detail that proof of intercourse wasn't necessary to find him guilty.

The court, in documents filed Thursday supporting the June 24 conviction and seven-year jail sentence, said all it needed was evidence that the former premier's "sexual instincts" were stimulated in exchange for payment.

It cited testimony that the evenings culminated with physical contact with Berlusconi "such as rubbing, fondling of breasts and intimate parts."

The court noted that the Moroccan teen at the center of the scandal, Karima el-Mahroug, better known as Ruby, received cash and jewelry in exchange for sexual favors. The court asserted Berlusconi was aware she was a minor.

Berlusconi denies charges.
