Oh my god, I can't believe I'm doing this. He is just in the next room, completely oblivious to what's happening between me and his best friend. But the way he fills me up, it's like nothing I've ever felt before. I'm supposed to be training for a marathon, but this is the only cardio I need right now. His hands grip my hips tightly as he thrusts up into me, hitting that spot deep inside that makes my toes curl. Shhhh, we have to be quiet. If he founds out about this little secret workout of mine, he'd lose his mind. Disclaimer: This content has been created using AI technologies only.
