Three pairs of beautiful mothers and sons hoping to conceive their sons' children join this incestuous bus tour that takes them to fertility hotspots and is filled with creampies! They pray for pregnancy at a shrine that can help with conception, and have creampie sex until the morning at a fertility hot spring! They cling to the sacred object of a huge penis and have standing sex with their sons, cumming inside them until their balls are empty! Fertilization is confirmed with a pregnancy test, and 10 months later the pregnant mother prays for a safe delivery!
