Tonari no Elf Mama
It’s been a few years since the treaty of friendship was signed between the elves and humans… and next door to my apartment live an elf mother and daughter named Sophia and Lilia. After eating a meal prepared by my elven neighbors, I felt a strange, restless sensation and became abnormally aroused. Just then, Sophia came to visit and explained that she had mistakenly used the wrong amount of a herb from her homeland. She said it had a powerful aphrodisiac effect, and if I didn’t ejaculate immediately, I might suffer permanent damage to my reproductive functions. As an apology, Sophia offered to help me relieve myself.
