The first is a young lady in the midst of childbearing, easily embarrassed with red panties and shameful stains. The second hasn't seen her husband in a while and recently bought a vibrator; her gaze when looking at a penis is too lewd. The third is a voluptuous wife with large breasts and a big butt, extremely lecherous and highly sensitive, even her anus spasms. The fourth is a young lady raising a child and has been quite neglected; her postpartum buttocks are spasming and erotic, with a lot of thick, white essence.
