Jacob Elordi looks super relaxed around Olivia Jade‘s famous folks … because he was comfortable enough to squeeze his scrotum in plain sight of the whole fam.

The actor and his girlfriend are on a yacht vacation with her parents, Lori Loughlin and Mossimo Giannulli, and Jacob’s keeping things loose around the fam.

Jacob just can’t stop fondling his junk … appearing to scratch his testicles.

Look closer … seems like these are the same swim trunks Jacob had on during another outing on this yacht trip … when he appeared to be aroused while suntanning next to Olivia.

Olivia’s sister and her boyfriend are also joining Jacob, Lori and Mossimo on the Mediterranean Sea … so everyone’s getting even more acquainted, and the couple is taking their relationship up a notch.

Check out the gallery … Jacob also busted out a few pushups on the yacht and took off his shirt to show off his toned physique.
