Ok, but I'll only do it for one of you at a time

"I'll do it but I don't want an audience," Ben said to the three of them. "Only one of you at a time, and I get to see tits or there is no show, OK?"

"I'll go first," Ann announced and she quickly showed Jen and Sue to the door. They protested Jen that she wanted to go first, and Sue that the whole thing was disgusting, but they went. Ann locked the door and said, "Let's get this show on the road. Let me see some cock."

Ben answered, "Let me see some tits."

Ann shrugged and pulled the white t-shirt up and over her head. Her massive tits were perfectly shaped and barely had any droop. The big nipples turned up slightly and the colder air in the room was making them stiffen nicely. Ben stood staring, his mouth open almost drooling when Ann shook him from his trance with, "Come on jerk off for me."

Ben dropped his pants and underwear and pulled his hard cock out. He began to fist it slowly pumping up and down the shaft, he fist squeezing and rubbing the head with every stroke.

Ann stood a few feet away leaning forward slightly so her massive tits swayed away from her chest and watched Ben masturbate for her. He was pumping faster now, his cock was dark and ready to spurt, and then he cupped his balls and said, "Ahhhhh, I'm cumming."

Ann was surprised when the first stream of cum erupted out of his cock head and landed at her feet. He spewed several more in rapid succession, his eyes fixed on her big tits and dark brown nipples. She had jacked off guys before, but it had always been dark and this was the first time she had seen a guy ejaculate up close. She was amazed at the amount of cum that he spewed, and she could feel her cunt grow wet with excitement.

Ann was even more amazed when his cock stayed hard, and actually grew about an inch in length and girth. Ben continued to masturbate, his hand pumping his swelling cock. "Can I cum on your tits this time?" he moaned as he jacked off.
