This is the sixth part in my ridiculous story of filth and incest. Previous chapters are in my post history and linked in the comments. Suggestions welcome.
Mandy bites down hard on the pillow as her brother violates her, tears of pain and joy streaming down her face. Unlike her mother she hasn’t had the advantage of a box of massive dildos to train herself with, her virgin cunt aches and quivers around Alex’s swollen shaft. Mandy has heard the saying “crawl before you can walk” but losing her virginity to a cock of this size was more like flying a helicopter before crawling, it was a trial by fire. But Alex is relentless, slowly forcing his cock into her virgin tunnel, ignoring her muffled squeals. Mandy thinks that Alex must be almost balls-deep inside her, but then she looks up between her legs and is shocked to see that he is only halfway.
“Oh god oh god oh god it’s so fucking big” she gasps, rubbing her clit harder.
