Isekai Series Dark Elf no Neito

Beings from a different world freely mingle with humans in the modern-day vision of the Another World Series. In this first installment, a young boy named Yuu finds himself in a strange situation when a certain Dark Elf named Neiht plays the role of his caretaker. Aside from the usual fare of day-to-day tasks, Neiht seems hellbent in making him ejaculate regularly as a means of calming down certain adolescent “urges”. Will Yuu be able to keep up with the clingy Neiht?
