VENU-819 - Father leaves for 2 seconds, mother and son start sex immediately - Kanna Abe

They don't really look like mother and son, but the eroticism is top-notch. Kanna Abe's blowjob, greedily devouring a horny cock, is as good as ever—that alone is worth 5 stars. However (as is typical for this genre), the father turns it into a comedy. In the first scene, the father leaves, and just as the mother and son start having sex in the entryway, he suddenly returns—it's a cliché, but it ruins the mood every time things get good, like some old-school slapstick comedy. The dinner scene with the three of them is just one big comedy sketch. Is this the standard format for these? It kills the vibe, so I'm docking a star for a 4-star rating. The actress and the male lead were good, though.
