We called out to a busty college girl from the swimming club at a training camp where strong schools gather, and asked her to cooperate in a test to see if an athlete could keep her Kokoro even if her nipples were twisted! The undeveloped nipples of the athletic college girl were so sensitive that she let out a sigh just by touching them lightly! When her fully erect nipples were relentlessly twisted, she climaxed for the first time in her life! When we offered the erect huge cock to the horny college girl, who couldn't stop squirting from her nipples with the final blow of a fast-rotating cyclone rotor, she couldn't refuse creampie sex even on our first meeting!
