IENF-355 My beautiful older sister felt sorry for my unremarkable self, so she agreed to a rubbing-style intimate act with the promise that it would be nothing more than that. But it felt so good for both of us that she became very wet, and before we knew it, there was a smooth, accidental insertion. Wait, is it in? But we couldn’t stop, and it ended with an internal climax! (IENF-355)

After seeing the cleavage and thighs of his older sister, who had fallen asleep drunk, her younger brother, who had just broken up with his girlfriend, starts pleasuring himself. Noticing this, his sister asks, Would you like me to help? and begins teasing him by showing her underwear and chest, then goes along with his advances. Before long, they move on to intimate touching, and things gradually become more heated. Even when she says It’s going in, his hips keep moving, and she starts to get carried away too.
