A Blast From The Past [EPUB ebook] 

Abigail had it all. The slim, attractive thirty-year-old teacher had a career on the up and a well-heeled husband who adored her. But she also had a past! That past was personified in Richard who, after ten years had found her again. He wanted to reintroduce her to the world of sex parties and orgies she used to be at the centre of. She needed desperately to stop him. Or at least her head did. Her body remembered the good times and the intense sex was like a drug, that she had become addicted to long ago – and was in danger of becoming hooked on once more.
