I compete with my cousin in a cock suck

These girls have been competitive since childhood, always being compared by their parents to see who was better in studies or in sports. Now they are two very beautiful women and have quite interesting boyfriends. They share a lot of things together and are still super competitive, so one night when they go out with their boyfriends they decide to compete to see which one of them sucks her boyfriend's dick better and makes him ejaculate much faster. The boys are uncomfortable with the girls' proposal, but the girls finally manage to convince them and they allow themselves to give one of the best blowjobs of their lives. The girls put into practice their best oral techniques, sticking each penis down their throat.
