'The Final Theorem of PtoM' is a new sexual technique developed by a genius in SEX. This technique, combining cowgirl and fellatio, truly creates endless pleasure. In the fast-paced cowgirl position, the female's lubrication will make the male genitalia moist, immediately welcomed by fellatio, then inserted again and repeated. Through this continuous act, sexual sensations are maximized, allowing for endless enjoyment of ejaculation. Why not immerse yourself in the spiral of pleasure with an alluring woman?
