My Ailing Childhood Friend Bound a Succubus System

My childhood friend, who has been sickly since childhood, bound a succubus system at the age of nineteen to prolong his life.

As long as he chooses a target and completes tasks like kissing, hugging, and cuddling with them, he can extend his lifespan. To complete the tasks faster and more smoothly, and to finally have a healthy and long-living body, my childhood friend chose his best friend, Qin Lian, as his target.

Seeing his pale and pitiful childhood friend, Qin Lian decided to cooperate as much as possible after learning about the situation. It's just a succubus system, just kissing, hugging, and cuddling, Qin Lian felt he could do it for his friend's life.

Later... The two of them kissed so much that sometimes they couldn't stop. My childhood friend covered his flushed face and made excuses, saying, "It's nothing, we've probably been single for too long, and haven't seen the world, that's why it's like this..."

Even later... Qin Lian sometimes couldn't control himself, and his childhood friend was still foolishly making excuses for him. My childhood friend said, "It, it doesn't matter, anyway we're both men, we often slept in the same bed when we were little, I, I don't mind."

Qin Lian said with deep eyes, "But I do mind. Now I am yours, and you must take responsibility for me."
