She's distracted and taken down. Ultraboy is too slow.

With the hot blonde superheroine distracted, Nishi launched a flurry of blows to her midsection, then followed it up with a savage elbow to the head, stunning Ultramom, who collapsed boneless to the ground on her belly. Soft fingers ripped aside the duralexx bikini bottoms, revealing Ultramom's pussy and ass. Shockingly, it was wet, whether from viewing Ultraboy playing with himself, or the sight of Nishi's hard cock, or the sight of Nishi's cock smacking her own mask covered face, or just from fighting a sexy futa who wanted to fuck her, it didn't matter, Ultramom was wet, Nishi was hard it was a match made in hell. Ultramom's legs were splayed apart as Nishi mounted her from behind, lining her huge cock up with the superheroine's tight cunt. "Knock, knock, slut, here cums the change."

Or so her swimming mind thought for a second, before the huge cock split her open and filled her like no cock ever had before. Then it was a match made in heaven. Ultraboy moved out, quickly, but quietly, sneaking up on the distracted futa as she wrapped her hand in Ultramom's long blonde hair and pulled her up, back and against Nishi's absurdly large cock. The futa's cunt was glistening as he approached, drops of her juice dripped down onto her balls as she eagerly. Ultraboy finally began to approach, hovering so as not to make any noise. Nishi's thighs slapped against Ultramom's ass as she fucked the superheroine as hard as she could. She was pulling so hard on Ultramom's hair that the woman was actually reared up like a horse, though her bare knees were grinding against the dirt.

Ultramom's resistance was gone, fucked out of her by the cock that stretched her pussy and her moans mixed with the slap of flesh on flesh and Nishi's high pitched squealing as she enjoyed Ultramom's tight pussy squeezing her cock like a vise. "Superheroine? Nah, just another stupid, weak, submissive superslut, like all the others. No heroes, no equals, the world is full of sluts and I just make more." Ultramom moaned in...agreement. That was a painful reminder that he had to get to her before Nishi came and transformed his mother into a dumb submissive futa nympho.
