Brazzers - Size = Stamina?

Keiran answers his door one morning to find the hot and adorable Lexi Lore outside. She explains that she’s running an experiment for her final college science paper and needs volunteers for her research. As it turns out, the big question at the center of her work is: “is there a correlation between cock size and stamina in bed?” Once Lexi explains her hands-on approach to gathering data, she convinces a hesitant Keiran to become her next subject.
