Improvised weaponry...

Ultraboy used the only weapon at his disposal. He came.

A rough hand grabbed Ultimamom's blonde hair and pulled her down. The superpowered ejaculate smacked the supervillainess in the face, blinding and stunning her.

Cock flapping, he charged Ultimagirl, shoving her to the ground. His hands searched the voluptuous woman as his cock left lines of cum on the woman's thighs and costume. His superspeed was enough to get the key from her belt and rise before either of the supervillainess's could respond.
