Masturbation session leads to monster cock cumshot

A blonde babe is enjoying a solo masturbation session when she feels a strong urge to cum. She starts to stroke herself faster and harder, moaning with pleasure as she gets closer and closer to orgasm. Suddenly, she feels a hard cock enter her mouth and she eagerly sucks it with both hands. The sensation of the big cock stretching her small mouth is enough to make her cum again, and she spills a huge load of cum all over her hands and the bed. The sight of her own cum is enough to get her going again, and before she knows it, she's back at it, licking and sucking at her own wet balls. The more she strokes herself, the bigger her cock grows, until it's the biggest monster cock she's ever seen.
