The father-in-law wishes to see his grandchild's face soon, but his son is impotent. The frustrating situation drives the father-in-law crazy! He tries to tempt his son's voluptuous wife with a paizuri lesson to induce sex at night, and an aphrodisiac massage to make her more likely to conceive. However, seeing that his son's attitude doesn't change, the virile father gets up and forcibly cums inside her, saying, "I'll make her pregnant!" He keeps cumming inside her until she's pregnant.
