I'm your stepsister! My stepsister's big ass won't let me sleep

My deluded stepsister thinks she can share her bed, without having her ass touched. But that's impossible, as much as she is unbearable she has a natural big ass that any man wants to caress and penetrate. This time I was lucky, she wanted cock days ago, because her boyfriend is traveling abroad. She said something about eating pineapple, does anyone know why?
