@Dominions SonSix Times a Day:
A shy boy gets the attention of a person, his neighbor who is hot. The boy has a foster mother and sister. The foster sister is secretly in love with her brother, and is VERY submissive, on the level of calling herself a sex toy. The mother, however, is very prude, Christian and so on.
The sister wears Puritan clothes too, because she doesn't like to show off, she just loves the brother.
The brother, the protagonist, has a large, long and thick penis, and attracts the attention of his neighbor, who is almost a second mother to him, Suzanne. She always stays at his house, and is his mother's best friend. Suzanne has a daughter, who is also in love with the protagonist.
Suzasse is a highly sexual, dominant woman, who is frustrated with her life, as she is married to a person who no longer love, they don't even sleep together anymore, the marriage is over, and she only stays with him because of the children.
She realizes that the protagonist, Alan, has a very large penis, and after a long time, she comes to the conclusion that she is in love with him. She wants to have sex, but more importantly, marry him. But she knows that it can't work because of the age difference (she's 36 or so), not to mention that she's also sexually interested in her friend, the protagonist's mother, Susan, as well as his sister, Katherine. She then, clever and treacherous as she is, devises a plan and puts it into practice.
She takes the protagonist to the doctor, and arriving there, in collusion with her, the doctor helps in the scheme that she thought. The protagonist apparently has a problem with his body that he always sleeps in the afternoon after school, which is quite abnormal, and the doctor says he has a disease that he has to cum 6 times a day. The explanation is bizarre, but the boy accepts, and so does his mother.
Then he continues to masturbate six times a day. Meanwhile, the story is developing. The Puritan mother slowly ceases to be a Puritan, his sister reveals her feelings, Suzanne herself finally reveals too, as does her daughter, Amy. At school, the protagonist also gets involved with several other women; like a teacher, and the whole cheerleading team.
There are some things that irritate me in this book, such as one of the women, Christine, who is one of Alan's passions. In the beginning, when he learned that he had to come 6 times a day, the protagonist tries to ask her for dating, she is very beautiful and busty, and she does not accept it, because although she likes him, she cannot see him in a sexual way since he is shy. Later, they develop sexually, and at the end of the book, the author has the assurance of not having a sex scene with her. At most, handjob and blowjob. Everyone was expecting it, it's annoying.
Recalling that one of the women (his slave) the protagonist shares once with her own son, and until the end he doesn't know what to do, if he keeps letting the share happening.
STaD is an illustrated book, has hundreds of illustrations, I think it is worth reading just for that reason even if it is not something you like, I highly recommend it.
