Sultry librarian Saki arrives with the boyfriend she has dated since college and secretly admits that she fantasizes about being taken by another man while he watches. Despite his objections, a performer fondles her full breasts, kisses her, and escalates the teasing until she moans shamelessly, sucks his hard cock, and gives him a titjob. After provoking her boyfriend with bold remarks, she takes the performer raw and cums repeatedly in doggy style. The ending leaves it unclear whether he pulls out or finishes inside, but Saki is clearly satisfied.
