No-Touch Ejaculation is a method where semen is naturally ejaculated without direct stimulation of the penis, allowing climax to occur even in a heightened state of arousal without physical contact. This technique drastically reduces the refractory period, enabling consecutive ejaculations.

Trying to maintain boundaries, she resists just before his climax—but suddenly, semen spurts out from his untouched penis, pulling her into an unforeseen development.
