Listened through episode 4. Each episode is roughly half setup and half erotica, but not much plot occurs in the setup portions. The lack of narration or other methods to describe characters' actions leads to clumsy porno-esque dialogue. The erotic scenes feature different pairings but the character dynamics are similar within the erotic scenes (man going along with a promiscuous' woman's advances). The voice acting sounds like they're just straight-up in a porno and names for characters include Dirk Hardoff and Wally Fapopolous, so I think the amateur porn vibe is intentional. The male characters in the erotic scenes (the relationships are mostly F/M with a single F/F relationship I could see in the episode summaries) show little enthusiasm for pleasing their partners after their own orgasm, which makes them unlikeable.
