My step-sister's seductive playtime with her toy

I've always had a thing for my step-sister, not because she's my sister, but because of her amazing body and the way she flaunts it. She's got these incredible big tits that are just begging to be played with. So, when I walked in on her the other day, playing with her toy, I couldn't help but join in. She's got this purple dildo that she's using to fuck herself with, and it's making her moan in pleasure. Watching her play with herself is a sight to behold, especially when she's got those huge boobs bouncing around. I can't help but imagine what it would be like to be inside her, feeling her tight pussy wrap around me. But for now, I'll just watch as she fucks herself with her toy, and hope that one day, she'll let me join in on the fun.
