The serious and big-breasted teenage sister, Kannna, kept a certain distance from her brother. Her brother's gadget-obsessed friend brought in a mysterious '催● app.' Once installed, the app could summon the target anywhere, anytime, and even alter their memories at will. The brother who obtained such a cheat item of the strongest kind summons his sister according to his desires and trains her into a convenient sex toy for himself… The sister under the effect of aphrodisiacs shows off her vulgar face of ecstasy, cumming from nipple stimulation repeatedly. A fuckdoll that can be summoned anytime, anywhere with just one app. #DickP
