Draco could only display a look of shock as he began to sweat, his rod still pushing in and out of Shuangtian rhythmically even though she was entering Beast Mode on him. Eva, on the other side, also gasped and closed her eyes, experiencing the sensation that Draco was enjoying under Shuangtian's 'mutation'.
Draco began to pant, but he could perfectly control his ejaculation with his bloodline boosting his ability, so Shuangtian couldn't beat him with just this. Meanwhile, she had hit herself with a double-edged sword as, if it was her intention to milk Draco and make him cum quickly, she had also affected herself.
The feelers and the perfectly constricting vagina muscles made her feel his shape all the more, intensifying the pleasure and sensation for both of them, which meant that the number of Shuangtian's orgasms, which were already frequent and plentiful, had now doubled in both frequency and intensity.
