Kat, in her braces and innocent 18-year-old attire, finds herself under the desk, servicing a massive cock. She takes it all, balls deep, her mouth stretching to accommodate the girth. Her granny watches, encouraging her to take more. Kat's eyes water, but she's determined, her tongue swirling around the shaft. The cock pulses, and Kat eagerly swallows every drop of hot cum, licking her lips, ready for more.
