LOL-197 - My brother's friend took me, and now my own brother is doing it too... The mental breakdown of my cute sister

Crossing the forbidden line! After being forced by her brother's friend, now her own brother joins in like a beast. She tries to resist, but the sheer size leaves her helpless and drowning in pleasure. Despite her cries of 'You're the worst, I'm your sister!', she's blackmailed into a twisted incestuous nightmare. Reduced to a toy for her brother's desires, he fills her up completely.
