Three pairs of beautiful mothers and sons hoping to conceive their sons' c** join this incestuous bus tour, visiting fertility hot springs and enjoying creampie sex to the fullest! They pray for pregnancy at a shrine that will help them conceive, and then have creampie sex until the morning at a fertility hot spring! They cling to the sacred object of a huge penis and have standing doggy style with their sons, cumming until their balls are empty! Fertilization is confirmed with a pregnancy test, and 10 months later, the pregnant mother prays for an easy delivery!
