A short explanation to what’s happening: He’s sitting on a pack of tightly packed towels. Veins going through under his legs are the ones supplying blood to the penis, thus restricting blood flow in them makes him unable to get an erection. He’s horny beyond his mind, but physically there’s nothing he can do about it. But don’t take this as a guide how to do it, as there is more to it. If you do try anyway, keep your session short and don’t put your whole body weight to it. Restricting bloodflow to any part isn’t good for more than very short periods of time and there are nerves, that might not like it. This is meant just for context, not to explain details of the technique 😊
