A.J. Lewis in How to Talk to Girls at Parties (2018)

The '70s-themed How to Talk to Girls at Parties centers on Enn, a teen punk rock fan who teams up with his pals John and Vic (played by A.J. Lewis) to infiltrate a London party, only to discover a strange cult, harboring a repressed alien who falls in love with him. Vic gets into the spirit with the cult and is convinced to explore some kinky sex-play. He's shirtless for the sequence.
