A wrestling match

"You ladies seem to be in relatively good shape. Might I suggest challenging one of the DKM sisters to a wrestling match?" asked Miriam.

The sisters considered.

"The rules would be simple. You and your opponent wrestle until one of you verbally submits. The loser is then inseminated by her rival's male champion" continued Maria.

"I like this idea. I want to hear the defeat in one of those bitch's voices as they submit to take a nerd load" said Felicia.

"Alternatively," interrupted Miriam, "You could challenge one of the guys. If you win, his girlfriend would be fucked in front of him. If he wins, naturally, he would be entitled to claim you."

The sisters considered. Who would they challenge?
