This slave's bulls have been stretched and roasted and now that they are swollen and sensitive it is time for some single tail action. Gemini strikes his cock and lashes the head of his dick with each stroke but his dick is in the way of his balls. She gets out her cord and tightly wraps the base of his junk and binds it tight. She takes the time to pull and smack his cock and whack his balls before she binds and extends his testicles and then ties his cock up and out of the way. Now she has a perfect target and she flogs his bound balls before going back to the single tail. Her lashes paint nice purple welts on his testicles. The slave shudders with intense sensation as he thanks gemini with each whip lash.
