just went so insane abt the idea of rodimus submissive puppy top
collared and leashed and fucking into you from behind, desperately trying to breed and impregnate you.
"I've been a good boy, right? right? please please please let me overload inside!" / "no, rodimus... good boys don't overload first... be a good puppy and make me cum..." as you tug the leash a little harder.
whining and whimpering as he tries soooo hard to be good. but his spike feels so good and you're so wet and warm around him like that...
he overloads with a loud whimpery moan, slamming in all the way, spike twitching as he fills you up with transfluid, drooling onto your shoulder, hips still stuttering as he tries desperately to keep his transfluid inside of you. you tug the leash again, a little harder.
"ah, you're not done yet. c'mon. you're not done until you've made me cum."
by the end of the night, he's lapping up around 10 overloads worth of transfluids from inside of you like a good boy :)
