You're Such A Dumbass, I Swear

Two heterosexual pals, JJ Knight and Pierce Paris, are chilling, narrating about recent sexual experiences, and competing with each other. At one point, Pierce boasts about engaging in "tight penetration" with a specific woman, which perplexes JJ. How is it possible to have "tight penetration" with only one person? That doesn't seem right.
Pierce stands by his story confidently, clearly revealing to JJ that he has no understanding of what "tight penetration" means. JJ, not wanting to be rude, desires his friend to broaden his knowledge on the subject. He shows Pierce a porn video illustrating "tight penetration”.
Eventually, Pierce realizes he misunderstood – what he experienced was "unrestricted deep oral” and not what he claimed it to be. Oops! As they carry on watching the porn, they both become sexually aroused. The explicit discussions have made them immensely excited and eager for release.
It might be awkward to masturbate next to each other, but many men do it, so it can't be THAT strange. They opt for mutual self-pleasure, leading to fervent stimulation. Eventually, they give in to exploring what it feels like to engage in sexual acts with each other.
Seems like a well-executed scheme!.
