Carlos Simoes and Fran Simoes, stepsiblings, claim to be studying together, but the thick tension between them is undeniable. Carlos, a strapping young man, struggles to hide his bulge as Fran, a temptress in glasses, leans over his shoulder, her breath hot on his neck. The 'study session' quickly turns heated, with Carlos' hands wandering towards Fran's thighs, and her own fingers tracing the outline of his cock through his pants. Their 'lesson' ends with Fran's mouth wrapped around Carlos' hard dick, gagging on his length as he groans in pleasure.
