Teen Sex 78 (1996)

New models are introducing themselves in Pia's agency office, including the hot Helena and a few boys. As usual, Pia tests the boys herself first: she is fucking one of them, the second one comes over and joins in. Helena, who was briefly on the toilet, joins in as the fourth. When Pia's assistant joins in too, the fucking turns into an orgy. At the end, Pia and Helena have a lesbian dildo session.
