Yuki, in her underwear, starts kissing a man and takes his erect penis into her mouth. Before even 20 seconds pass, she is made to swallow a large amount of semen! She encourages his recovery with fellatio, and when Yuki mounts him, she writhes her hips saying, 'It feels too good.' However, while he's thrusting from behind, he suddenly ejaculates again, leaving her unsatisfied. 'Hurry up and get hard,' she says, making him erect again through handjobs and penis flipping. They merge once more in the cowgirl position. Will Yuki be able to reach orgasm with this premature ejaculator...!?
