"You can cum three more times, right ?" , says the narrator. He's referring to a wife who's been made to "cum many times" by her "scentile brother in law" before she returns home. She's got to do it all the time, he says, because she's "made to cum" by "her peerless brother in-law" . The narrator and his wife are having a little fun at the thought of having to do this again. They're so excited that they can't even hold their pants down anymore, which makes the whole thing even more awkward. We're guessing that's because you're worried that your daughter is watching them . But the narrator and wife are totally chillaxing about it, and they decide that they'll just do it again this time.
