I used to concentrate on the bargain bin at my preferred 42nd Street porn shop. That meant many compilatons. I used to see Angela Summers teamed with Stacy Nichols, who seemed familiar with each other sexually off the screen, in these early amateur-ish early gonzo scenes.
She was very good at getting Stacy off.
For some reason, on the reciprocation Angela always made Stacy take the dildo out of her before she came. Angela would rub her own clit very fast and hard to achieve release.
