[Tanukine (Nekoro Tanuki)] Big sister succubus – Regression sperm milking training

Nao-kun's voluptuous, horned big sister succubus decides her little brother needs intimate regression training after catching him aroused despite having a girlfriend, pinning the flustered sole male against her massive, soft breasts and very long hair with a sweet, possessive smile. Her yandere femdom discipline turns from taunting kisses, handjobs and paizuri into a relentless, crotch-tattoo-flashing cowgirl milking that treats his erection as an invitation to be drained, coaxing blowjobs and deep nakadashi creampies while her monster girl hips set the rhythm. Torn between embarrassment and dizzying pleasure, he finds himself melted into her loving, obsessive embrace where she promises endless, exclusive affection if he will just be honest and admit he belongs only to his big sister.
