The Fukada-style handjob study method promises complete control over both grades and semen output. Her slippery fingers switch seamlessly between slow teasing, high-speed stroking, and firm up-and-down motions, only for her to order a stop right before ejaculation. The mischievous smile she wears while gripping a throbbing cock makes the torment even harder to resist. Precum pours out during this devilish private lesson where cumming is forbidden until she finally allows an explosive release.
