FSDSS-921 | A life of cohabitation where her girlfriend, a devilish girl who loves her boyfriend's (masochist) nipples, constantly scratches them with her nails, causing him to cum over and over again

[Agonizing! Nipples scratched with nails] It all started with my sensitive reaction to nipple teasing. Since then, every day, my nipples are scratched with nails and teased with a devilish expression, "You're cute" and "That feels good". Every time they rub, my body reacts with a twitch, my brain goes numb, and the pleasure makes my pre-cum overflow. No matter where I am in the house, I am teased by my nipples scratched with nails, and I am driven by the urge to ejaculate and have sex to the limit of my endurance. From the time I wake up until the time I go to bed, my nipples and dick are caressed all the time, and I can't stop climaxing. I'm a masochist who can't stop climaxing.
