Handjobs aren't just about speed! Piston fucking isn't just about speed either! The most pleasurable thing is a piston with a [constant rhythm]! It's not fast... but it's never slow... every second brings you closer to the eventual climax! Nao Jinguji, who boasted that "sex without variation seems boring," is gradually broken down by this constant piston! She wants it faster because she's almost there, yet it remains constant. She just came and wants it to stop, yet it remains constant. Her composure vanishes under the emotionless machine-like hip movements that combine teasing and pursuit, leaving her with a melted expression... Even after the creampie, the tireless machines continue to maintain a constant rhythm, not stopping even when the cum flows back out of her pussy! With a metronome-like precision, they accurately strike her sensitive spots until she's drenched in sweat, writhing in ecstasy! The second installment of the popular "Actress Killer" project!
