Toesex (also known as toejobs), just like a footjob or footsex, means that a girl uses her toes and/or toenails to jack off or tickle a man's dick, for sexual fun and pleasure.
Beverly has sexy red toenails after trimming and painting them. She gave me the best toesex ever - by using both of her feet, using her first and second toes to softly caressing and pinching my dick. She also dig her toenails on every part of my dick and balls. Oh... that girl is so hot! I love her for that.
