You've come to the library looking for books about the elusive phenomenon of multiple male orgasms. The busty librarian informs you that unfortunately, they don't have any research books on the topic. However, she has something better - first hand experience! She says she would be happy to tell you everything she knows about multiple cum shots. Edging, she tells you, is the key. Follow her instructions and you'll soon be cumming three times in a row. You never know how educational a visit to the library can be!
