I request my stepbrother to massage my butt with oil, leading to an unexpected penetration

After a steamy shower, I was craving a soothing butt massage. I turned to my stepbrother, knowing he had a talent for it. He was more than happy to oblige, and he had a new bottle of oil that he eagerly applied to my curves. The sensation was incredible, sending shivers down my spine. As he continued, his fingers ventured closer to my most intimate area, and before I knew it, he was probing me with his thick member. The surprise turned into pleasure as his hands and mouth worked magic on my back and ass. The intensity built up as he thrust deeper, his cock filling me completely. The sight of his big dick disappearing into my tight hole was too much to resist, and I found myself craving more. It was a wild ride of unexpected pleasure, leaving us both breathless and satisfied.
