Kaligosto Loboto's "Psychonauts" takes a dark, kinky turn when the lead researcher, unable to resist his curiosity and lust, decides to test his subject's limits. After administering a potent sedative, he uses his knowledge of the human body to stimulate the subject's prostate with a precision that's equal parts science and sadism. The subject writhes in pleasure, his cock leaking pre-cum onto the examination table. The researcher, now sporting a raging erection, lubes up and fucks the subject hard, making him beg for more as he races towards his climax.
