Warm up and then breeding

As they were trained, they would start by 69ing each other to get both the boys dicks hard and the girls pussies moist. The girls were on top of the boys sucking their dick while the boys started licking the girls pussies. They all enjoyed the tease until they felt ready.

The boys then got on top of the girls and had their legs spread. So enough, the boys pushed their dicks into the girls pussies making them moan.

"Hey!" Trix yelled to Conk. "I bet I can last longer then you!"

"Your on!" Conk replied as they fucked their sisters harder.

Both Kisx and Brusa smiled at each other and held hands as they moaned letting their brothers have their way with them. They were hoping for healthy and sexy babies.

Trix and Conk kept going trying to hold off their climaxes to win the challenge.
