A seemingly close-knit sister and brother were approached with a request for a 'consciousness survey' that involved lewd questions. Eager for pocket money, the sister's breasts were groped, and kisses were exchanged through clothing... The pure-hearted younger brother ended up getting an erection! Since they're siblings, actual intercourse is off-limits, so they resort to dry humping. Before long, the sister's pussy was soaked. With the promise of extra pocket money, a single phrase, 'Want to have sex?' led to smooth penetration!
