Zhang Fei was lying on the bed with a satisfied smile, with Zhang Lin curled up on his chest looking exhausted. "Your body became stronger after your demon rank rose to the Demon Monarch Rank, and your stamina became more abundant, Lin'er."
"Hehe! I didn't expect my body to be this strong either, Big Brother." Zhang Lin's hand continued to move up and down her big brother's erect dick. "At first, I was overwhelmed after you made me orgasm twice because I haven't had sex with you in over two years, but my body slowly adapted, and I don't feel exhausted even though I've orgasmed so many times."
Zhang Fei kneaded her breasts. "The Seven Supreme Demon Ranks are indeed impressive, and each rank will increase our body's strength even more. If your demon rank reaches the Demon God Rank, your body will be even stronger."
