Fun in the Sun by Poppy Deveaux
Nat and Pete are a young couple who are taking their first vacation together to the tropical island of Barbados. When they arrive, however, it is not as idyllic as it seems for Pete is plagued with insecurities and jealousy of other men admiring Nat.
The trip gets off to a bad start but Nat meets the mysterious older woman, Jessica, at the bar, who offers her some words of wisdom. Over the first couple of days Jessica keeps making an appearance and then makes Nat a strange proposition, an offer that Nat doesn’t think she would ever take. However, when she talks about it with Pete they decide that there’s something irresistible about this woman and perhaps this vacation is the perfect time to explore their hidden desires.
Jessica takes them on an erotic odyssey and teaches them that love is only the beginning of pleasure.
