Gag Reflex by Marata Eros

Dara is a cougar on the prowl. When erotic circumstances present themselves, she takes advantage in every way possible. Best friend Zoe and traveling buddy, Isabella, get wind of the fun, and the trio experience sexual fantasies of epic proportions.
When Dara plans to travel abroad with Isabella, she realizes how naughty she’s been by putting off her medical examinations. Dara invites Zoe and Isabella to her communal appointment with a fleet of young, eager doctors ready and willing to accommodate ladies of a certain age – or all ages.
When interns join the adventure, the women find they need more thorough exams than they ever dreamed; including Isabella.
