Sounds nice if it's a person who deserves it. Not exactly "hot", though... but it'd definitely be a joyous moment. As long as whoever was exposed to it deserved it....
What'd be hot, though, would be to cut open your true love and spread her intestines outside her body, and kiss her guts and fuck her while she'd be like that... open and all bloody... then, when you'd be about to come, spread your cum on her guts and then close her up with the cum left there... and she just loved it all and would be fine, afterwards... and you'd hold her and be aware of that the two of you have done the most beautiful thing there is to do.
...Too bad it's not possible in "life". At least it is in "death", though... or the "afterlife"... whatever one should call this other stage of existence. Meh... so wish I could do it if I ever find my true love, but not really all that easy to perform in this sucky world... at least not without leaving massive scars and a long healing period... neither desireable.
