Milking play between couples, centered around gonzo-style filming as preparation for parenting. These girls believe that careful planning is essential for happiness. Wishing for marriage and longing to have children, they become emotionally and physically aroused, engaging in experiences to prepare their bodies for the day a baby arrives. Documenting their couple's parenting practice, these girls aim to become good mothers who can produce plenty of milk, enjoying pretend motherhood using breast pumps. <Girls' impressions> "Wow, it feels like I'm actually being sucked out///" "It's making a schop-schop sound, such a weird sensation///" "It's sucking me so gently///" "They're getting so full///" Adorably shy and cute reactions. Never did they imagine they'd grow jealous of a breast pump! Moreover, using the pump makes their nipples increasingly sensitive. While the pump is important, experiencing real sucking is also essential, so they move on to having their big breasts sucked—chuu chuu chuu. "Mmm, having my breasts sucked like this feels so good///" "Why are they getting bigger? They're harder than usual///" Sucking, kneading, breastfeeding play—soon the mood turns erotic, and they end up having sex. "I really want a baby now... Daddy, let's make a baby?///" After all the breast play, their entire bodies become hypersensitive. Their pussies are slick and wet, moaning cutely like babies. They're hornier than usual, cumming repeatedly. "Aaahn, it's too much, feels so good, cum inside me///" Their tightness is overwhelming, drawing the cock's milk deep into the womb—spurt after spurt. So aroused that more semen than ever oozes out thickly. "We have to make a baby, so let's keep going?///" Just once isn't enough—they spend the entire day having baby-making sex over and over. In the end, the cock gets milked even before the breasts. The ultimate breast pump indeed.
