Mother-in-law calls from the other side of the door. "Mind if I come in?" The husband panics, replying, "Ah, Mother... sure, come in." She enters, looking slightly uneasy. "Sorry to bother you, but I saw your wife running out crying, and I got worried... Did something happen?" The husband answers, "Ah, no, nothing..." But adult DVDs are scattered around the room, and the mother-in-law picks one up. She says, "I see... Look, I don't mean to interfere in your marriage, but how are things going with having a baby? I'd really love to see a grandchild. Instead of watching these videos alone, why not try with your wife?" The husband murmurs, "Yeah... I guess..." and falls silent. She asks, "Is something wrong?" He replies, "I don't actually want to watch this stuff. I'd rather be with my wife. But she keeps rejecting me..." The mother-in-law is shocked. "What do you mean?" He confesses, "...It doesn't fit.

After a pause, she says, "Um... could I... see it?" He's shocked. "Huh!?" She explains, "Ah, no, it's just... I want to meet my grandchild soon. This is family business. I need to understand." He asks, "Are you serious?" She nods firmly. He hesitates, then says, "Alright..." and slowly removes his pants and underwear, revealing his massive erect cock. The mother-in-law stares, frozen in shock. He asks, "So... what do you think? Is it really that big?" She can't look away. "Yes... it's huge..." He says nothing. Neither does she. After a moment, he asks, "Um... Mother... is that enough?" But she whispers, "Not yet... let me look a little longer..."
