On a second look at the picture, penetration may not be possible if anatomical accuracy is to be considered. This is because Parsee is leaning too far forward so that her cooch is pointing downwards in front of Yuugi. Realistically, the best that could happen is that Yuugi's rubbing against Parsee's juicy parts. A realistic picture of penetration happening will have Parsee leaning backwards (preferably magically levitating or performing acrobatics). However, it would not be possible then to see Yuugi's face from the same point of view as the original drawing.
In the immortal words of littleshrimp: FOREHEAD GENITALIA.
Q: How far could you see if you had a 12-inch dick growing out of your forehead? A: You wouldn't be able to see at all; the balls would be in your eyes.
