I completely adore you.
You’re smart and gentle and genuine. I love that you’re shy like me. I love that I can be myself around you. You smell nice, too.
Although our friendship has been restricted to innocent flirtation thus so far, I want you to know that I fantasize about doing lewd things to your body quite often. I get a particular thrill out of imagining the guttural moans you might make as you approach orgasm.
I hope you’re flattered rather than creeped out. (But let’s be honest here–gentleman though you are, you’re also a 21 year old male. I bet you masturbate at night when you think of me, too.)
