"Faster! Harder! Rougher!" Arissa says.
"HAA! HAA! HAA!" The assassin tries his best not to orgasm but it doesn't looks like Arissa is going to cum before him. In the end he swallows his pride and admits defeat.
"I think I am about to cum." - He shouts.
Arissa grabs a nearby knife and cuts his throat. Blood gushes out as he falls to the ground silent. She thrust the blade in his heart again and again. And kills him too while his dick was hard.
