Feeling good all by myself... <3 I'm really sorry <3
I didn't bother factoring in the moaning/onomatopoeia but the last line I had a bit of trouble with, particularly with "気持ちよくなって" as that is "気持ちいい" compounded with "なる", i.e. to become, and while I understand what that means I'm not sure how you'd phrase it in English since it literally would be "becoming good feeling," or "starting to feel good," or something like that and it just sounds really awkward.
I'm just me that's feeling good...I'm so sorry!I'm cumming! Again.....I'm cumming!The...the park is in trouble but....Ah!...No, it feels so good!I'm the only one feeling...so...good, I'm sorry!
