The semen bull is forcibly milked by the semen extractor he designed himself.

After fixing the semen extractor in place, the machine starts sucking and stimulating non-stop.
Even though it's already very sensitive, it's still forced to keep playing.
It held on for over ten minutes, body trembling the whole time, yet still not letting itself cum.

Finally couldn't hold back anymore, the thick semen was forcibly squeezed out.
The whole body shakes while cumming, really got ruined by his own machine.💦
