Need help - Specific vintage scene ?

Hi everybody

I search a specific "vintage" scène with 2 young blonde girls and 1 older man (with a brown beard if i remember good). Girls are virgins and know nothing about sexuality.
The man is lying on the bed and girls kneeling on each side of him. One of the 2 girl is interested by the cock and want to suck it. She wear a new red panties and don't want to smear it, the man proposition is to remove it..

Thanks a lot in advance
