I dont think this is rape. Rape is considered rape when a person says no. Tiger didn't say no and althoug he didnt say yes out loud, his thoughts were saying yes. If it was rape, Tiger could have woken up and said no, but instead he let Bunny continue on.
You're wright when you say that in those circumstances it was totally okay (they both want it, ect... it's a doujinshi bonus just for sex anyway, ect...), but begining something like that without the consent of the other party, when you know he can't give his consent (sleepiiiiing~), is called rape. And because the raper is your boyfriend doesn't mean it's not rape.
Anyway, it's not like I'm saying this doujinshi is "horrible because it's rape OMG", I just want to precise that "Er, in reality it's not cute or sexy you know ? It's called rape. But I enjoyed it anyway ┑( ̄Д  ̄)┍"
What part of "because the raper is your boyfriend doesn't mean it's not rape" do you not understand ? Σ(  ̄□ ̄||)
Fun fact for you (this is not fun) : According to a French study in 2018 aproximately 94 000 of more than 18 years old women were victims of sexual assault or rape, 9 of 10 knew their assailant, aaaaaand 45% of those assailant were the spouse or an ex-spouse.
I don't want to point out the numbers here, I want to point out that you can get raped by your damn spouse. For real. Let's promote consent. Consent is sexy. Consent is hot. I love consentual SM relationships with weird kinks ლ(´ڡ`ლ)
They get right again at the end but... Bunny-chan, this is rape, even if you "know he want it", begining to lick his chest, when you don't even know that he is not sleeping is called rape you know...
Well, the art was sexy thought
