Rubbergirl was horny all day long but wanted to suspend her orgasm as far as possible. So she needed to be tied up in something heavy for a long time. Her master was to decide for how long. He knows how much she can handle so he made it hard on her. For a start a thick rubber catsuit. Over that a leather straightjacket. Followed by the first rubber bag to keep het warm, then a second heavy rubber bag to make it more heavy. Finally he parked het in the inflatable total bodybag from rubber magic. The electric pump broke down so he had to inflate her by hand. The pressure in the bag raises slowly until she is floating in all those layers of heavy rubber. She is left on her own in the dark several times and for a long time. She meditates to fight the cramps in her arms but she won't disappoint het master. Finally she managed the full 4 hours and deserved a fine and overwhelming orgasm. Lets make it 5 hours next time.
