Jack and Beatrice are being ridiculous. They know they shouldn’t be doing the things they’re doing but they’re doing them anyway. Beatrice knows, no matter how much she’s craving cum, she shouldn’t be nursing on her grandpa’s cock. And, likewise, Jack knows, in exchange, no matter how much he’s craving mother’s milk, he shouldn’t be nursing on his granddaughter’s mammoth breasts. But that’s exactly what’s happening. It’s madness! And there’s nothing you or I or anybody else in the family can do about it!
