     there feeling, and most gently indeed, squeezing those tender globular reservoirs; the magic touch took instant effect, quicken'd, and brought on upon the spur the symptoms of that sweet agony, the melting moment of dissolution, when pleasure dies by pleasure, and the mysterious engine of it overcomes the titillation it has rais'd in those parts, by plying them with the stream of a warm liquid that is itself the highest of all titillations

2. The process or outcome of titillating.
