Peter Grill and the Seeds of Rational Thinking. Book 5

Peter Grill managed to restore his fiancée to her former appearance, and a dragoness joined his harem. Sister Lucy and his future father-in-law arrived at Peter's freshly purchased house right during his revelries! And just as he slipped out of the trap, he received an indecent proposal from his former master. What awaits Peter if the tigress does not accept refusal?
Book 5 contains two original volumes, 9 and 10.
