Actually quite a few of us recall a story you posted a long time ago that was very much bordering on rape. As highlighted in recent rape cases, consent isn't as clear as many of us think;
CRIMINAL CODE 1899 - SECT 348
consent
348 consent
(1) In this chapter,
"consent" means consent freely and voluntarily given by a person with the cognitive capacity to give the consent.
(2) Without limiting subsection (1) , a person’s consent to an act is not freely and voluntarily given if it is obtained—
(a) by force; or
(b) by threat or intimidation; or
(c) by fear of bodily harm; or
(d) by exercise of authority; or
(e) by false and fraudulent representations about the nature or purpose of the act; or
(f) by a mistaken belief induced by the accused person that the accused person was the person’s sexual partner.
Those last 2 could very easily apply to punting situations.
