Submitting a straight alpha into a beta bitch

Jonathan wakes up to what looks like a normal day. He gets up, streches his big musles and takes a shower to go to work at the hospital. His body is very well conserved for a 28 year old, his hairy and muscular chest and tall nature make him a real stud. His dark hair, lightly tonned white skin and green eyes make him a piece of eye candy.

This young doc has a really big secret: he loves submitting man with a smaller dick then him, and although, until now, he only took thing so far, he is ready to take the next steps to turn what he calls "alpha man" (really masculine domineering cocky straight man) into his submissive, man loving, humiliation moved, sissy "beta bitches". He had this idea on his head for months now, but he hasn´t had the chance to put it in practice yet. Until today.

Doing that is gonna be easier, once he got an anaconda between his legs, a 10 inches long, thick, uncut huge dick. Jonathan also knows that by pressing the right buttons, he can submit anyone, men or women.

That said, how should he begin his journey to create a harem of betas?
