After not having my machine for quite some time (how could I forget?), I felt like shooting some erotic videos. I wanted to use it in a kind of "submissive" pose, that is kneeling over the machine, and being recorded from the rear (which many viewers seem to like...).

Moreover, I felt like trying out some ass fingering action, which you might know is not my usual "mode of operation".

I wanted to try out two different setups of my stroking attachment. As you might have seen in other of my machine videos, I constructed a Quickshot attachment that has an additional feature, namely a gizmo that can be used to simultaneously stimulate my perineum / ballsack area. 

The original construction, shown on the left, allows for this addtional stimulation only if used from behind. To be more flexible, I drilled another hole in the attachment's base, so I could mount it the other way round, as shown in the image on the right.

In the first video, I used my "classic" setup, that is with no ballsack stimulation.

The next day, I tried out the other orientation. Which was quite an improvement! This way, I could have my perineum / ballsack area stimulated simultaneously, and even my asshole! Or sticking my finger into my ass at the same time - triple stimulation! It felt great!
