Let's See If It Fits

When Serena Sterling stumbles upon a condom lying in the washing, she jumps to conclusions about her stepdad, suspecting he might be unfaithful to her mom. Intent on investigating, she confides in her stepbrother Jodie Johnson. Jodie, however, reveals that the condom is not their dad's but his own.
Serena is skeptical and devises a unique experiment- to check if it matches. Undeterred, Jodie sees her point but questions its utility once aroused. In a bold move, Serena exposes her irresistibly supple breasts, vowing not to let the condom go to waste.
Stirred by the temptation, Jodie complies, demonstrating the condom's snug fit. Convinced that her stepdad is not straying, Serena proceeds to pleasure her stepbrother, commencing with erratic fellatio. Soon after, she sheds the sheath realizing its mutual proprietor and resumes her lecherous behavior, maneuvering her drenched area onto her brother's sizable shaft, initiating a rhythmic grind.
Jodie admirably diversifies their positions, skillfully maneuvering his stepsister irresistibly as she peaks on his throbbing manhood. Completely satiated by the relentless throbbing, Serena permits Jodie to spurt across her features.
