I love the way that dick spasms uncontrollably at the point of orgasm. You can really tell that she in pure ecstasy. Imagine the air rubbing against the wet glans, producing an exquisite sensation, it would cause enough to produce another spasm at least. Fans of the doujin will be in for an extra treat, as the olfactory description given in the original doujin of the penis and semen combined will the visual stimuli of this classic scene re-mastered into a moving gif. will make for a sweet experience indeed, its almost like you're in the room with her. The captivating, almost grotesque penis of hers is mesmerizing. You can imagine the scent offf that thing from just being in the same room would drive any otaku crazy, let alone being in the same stall and feeling the heat coming off. The moment of orgasm is amazing, the way the vagina cums and spasms in unison with the penis makes for a vivid treat for the eye, you can almost feel it. The way the penis deflates is also brilliant, it very rarely you see artists focus on the penis deflating. The way it lets one last spurt of semen out as it withdraws, the pearly white string of semen spanning her panties and the tip of her penis has a magical quality to it.
Overall, this is an exceptional gif, but it drive readers of the original doujin insane.
