A story depicting a couple with a significant age gap and their journey toward parenthood. The relationship between the older man and young girl progresses as they prepare themselves for conceiving a baby. The girl tries a breast pump for the first time, experiencing a simulated motherhood sensation, reacting realistically to the sensation of her nipples being sucked. She shyly exclaims, "I've never used this before, so I'm excited!" "It feels kinda good when my nipples get sucked..." "I'm getting all turned on now///" Using the pump makes her nipples more sensitive, helping her realize how important it is to have her partner suck her directly. Scenes include him sucking and fondling her big tits, enjoying breastfeeding play, gradually building a sexy atmosphere as she murmurs, "They've gotten so big... ready to make a baby?" Her entire body becomes hypersensitive from the tit torture, causing her to climax more than usual. "Aaahn, so good! Cum inside me///" "My pussy's so tight, shooting your cock milk deep into my womb—Bburrrrr!" "I'm so turned on, you're spilling way more baby juice than normal, it's dripping thick~" The creampie-filled sex doesn't stop after just once—throughout the day, they keep having baby-making sex repeatedly, showing their passionate effort to conceive.
