Putting on a Show

... boxes around the stage respond. Just towards the end of her big monologue, in her excitement, she half leaned forward, strengthening the bobsled analogy, then standing slightly, dropped back down, wedging Pete's not entirely flaccid member against the crack in her butt. The feeling of his inner thighs against her hips and outer thighs was already a cross to bear. This was almost impossible. Try as he might, he felt his member stiffen and unfurl along her ass crack.

He prayed she wouldn't notice or be too caught up in the play to realize what was happening. Nothing happened for a while, and he began to relax. Beth's speaking part was pretty much done. His own few utterances were as part of the chorus, and he managed to concentrate enough to get them out. His cock slowly began to soften slightly. He was still unbelievably aware of the flesh on flesh and the pressure pushing back against him, but it was easier to concentrate on the show around him.

What he didn't count on, was when the cast had to try to make their boxes move on stage. This was achieved by shunting one's weight, planting the feet and, essentially, thrusting with the bottom.

He was beyond shame now, and decided he would make amends later. He had warned her after all. Beth, however, didn't seem concerned at having her brother's erection squashed along her rear crevice. On the contrary, she gave her ass a little wiggle, stimulating his cock even more. Now, it felt like it was ready to burst.

"More like that." Beth whispered again. "But hold me tightly, so we push the box together."

Reluctantly, he snaked his hands around his sister and joined his hands in front of her chest, careful not to touch anything sensitive. Over and over, they shunted in time with the cues. Over and over his cock slid along her ass crack, each time, pushing deeper against her. For the last big push, Beth grabbed his hands in hers, forcing them against her breasts where he could feel her erect nipples under his palms. To make matters even worse, she seemed to give an extra big push back into him with her ass. The sensation in his cock was almost unbearable. He was ...
