BKDK steampunk AU just calls for the horny twist of ABO with omegan hysteria. Unmated omega Deku displays symptoms of anxiety and restlessness, and sent to an alphan Dr Bakugou to treat his repressed sexual deprivation, with steam powered fuck machines…

Deku doesn’t agree to go at first. He has so much to prove as one of the first omegan engineers, working overtime to show that omegas are just as technically skilled and inventive!

He’s completely devoted to his work and doesn’t have the time for an alpha, but his bosses are noticing the nonstop mumbling, the lack of sleep and nervousness that can only mean one thing.

Luckily for him, Bakugou is a pioneer in his field.

Luckily for him, Bakugou is a pioneer in his field. He has a chemically brewed blend of alpha hormones to relax any warry omegas- he applies them to their pelvis and inner thigh with a tender massage.

Once the juices get flowing, he moves to hydrotherapy- aiming a powerful jet of water at Deku’s genitals, making him whine and wiggle in his medical chair. The constant stimulation directly aimed at his engorged parts have any omega coming immediately and Deku is no different-

However Bakugou doesn’t expect the giddy, orgasm-intoxicated omega to make suggestions for the water pressure and spray patterns.

He brings Deku again, and tries the newest, most cutting-edge machines on him.

“I call this one Howitzer Impact.” He says with a smirk, and Deku is then introduced to the first rotating dildo- Bakugou grips the handle attached to a wheel and spins with all his strength,

and the textured dildo spins inside him, little bumps brushing and pleasuring his sensitive inner walls in every spot.

The next machine takes it to the next level- the closer they get to an alphan cock fucking with all it’s strength, the happier the omega is.

Some of Bakugou’s colleagues are uncomfortable with how close his inventions are to the real thing- his model has an inflatable knot, a cum tube, and an engine more advanced than some of the ones used for vehicles;

it can thrusts at an incredible speed and so much force that Deku has to be tied down to the medical chair.

“Deeper Kacchan, I need it so bad… The friction is perfect, but impact is…”
Bakugou stares at his patient, pupils expanded with desire and disbelief.

The machine is already set to pound with strength that would never be approved by the scientific community. But how can he stop, when Deku is splayed open on his chair in front of him, squirting on the floor, gasping for air and screaming ‘more coal!!!’
