Fifteen-year-old Toby was very happy living alone with his mother after his dad left them. He felt conflicted, and even ashamed, when the raging hormones of youth made his feelings for her more... complicated. Then she announced that she was going on a date.
This isn't a follow up from Adventures with Mum's, but it does feature the same characters, like an alternate universe type thing. Gemma gets the chance to stay in a cottage on the coast for work, and takes Mike and his friend Scott as it coincides with Mike's birthday. The boys procure some aphrodisiac pills hoping to meet some girls, but unexpected things happen.
A family discovers its secret tradition when it is forced to resume them, and horror turns slowly to acceptance and enthusiastic embrace. Based very lightly on the works of H.P. Lovecraft, but without tentacles. Written from the father's point of view. A little bit slow to start if you are reading it just for the sex.
Hot aunt gives her nephew a hand-job and a blowjob, and then an education in how to please a woman that ends up with his cock in a vagina for the first time. Then they get a surprise... (Note that some of the codes apply to later chapters)
