It’s not someone who decides to swipe a wallet the next morning though is it? It’s premeditated and deceptive.
This is getting into gross territory and I have absolutely ZERO interest in discussing what constitutes rape or a victim (which has little to do with any given country’s laws anyway), but since your last question is easy to answer, here are the results of a cursory google search:
Rape by deception, also known as rape by fraud, is a crime that occurs when someone deceives a victim into having sex by making false claims. The victim would not have consented to the sexual act if they had not been deceived. Rape by deception is recognised in the laws of many jurisdictions, including the UK and the US.
