Although my 29-year-old wife has been with other men, the most frequent fuckbuddy is her boss for the reason that they’re in close proximity five days a week. He is one of two who not only doesn’t know I’m aware of their sexual relationship but approved it with my wife before it began. But there's another reason she wants him to keep fucking her. I have no idea what makes him so different, but his stamina is remarkable. She says most guys last maybe two to seven minutes, like me. And after that, they’re usually spent until resting awhile. But he isn’t like that. She said he typically fucks her for up twenty minutes at a time before spurting inside her. And then, his dick rarely deflates. His cock is large; he tells her he's nine inches, the largest she has experienced. A few minutes later, he mounts her again. For that reason, she occasionally phones me from her workplace to tell me she will be spending the night with him if she feels the need for a full night’s satisfaction. She describes her reactions as crying out to him to give it to her, that she is wild and insatiable for multiple fuckings. She has told me more than once that his size is the main reason for her addiction to him; it's so different from anything she has known. In response to my once asking if she could quit if I wanted her to, she said she didn't think she could; she added, "Well, maybe if I could taper it off, but that would take a long time. I really need it." She said the feeling of his big cock in her willing pussy is like bathing a python but a heck of a lot more fun. I don't really want their relationship to end anyway. Their relationship has resulted in several perks on the job like being able to take a day off with short notice. She also enjoys being fucked by me and others, but as she once said, "He's got something extra." No kidding. I don’t understand how anyone can go that long, but I find that rather amazing. Sometimes, I wish that she could tell him I know about it so that I could watch him pummel her a full night. Common sense brings me back down from that, but it’s a frequently occurring thought.
