Yes, he just keeps swelling bigger

“Yeah, it feels real good,” Sue answered him as she brought her other hand up to twist and pluck at her swollen nipples. “It makes me feel all tingly down there. It makes me feel so fucking turned on.”

She moved closer to Ben as he started to rapidly pound his cock again. His hand was rapidly moving up and down his thick vein covered shaft. His fat cock head was thick and huge and she could not believe that it would fit inside her, it was so big.

Fuck my cock feels so good. Fuck it turns me on to look at you. Do you get yourself off too? Tell me how you do it sis; tell me how you make yourself cum.”

She avoided his question and said, “What are you thinking about right now. What do you think about when you jack off?”

“Uhhh fuck, I think about your nipples and how I would like to fuck your pussy. Fucking cum all over your tits, have you suck me off and let me cum in your mouth, or blow my load all over your face.”

Sue had moved very close to Ben’s big cock and she was mesmerized by the sight of his fat cock head pumping through his hand over and over as he fisted his hard cock. Fuck I’m going to cum again Ben moaned as she leaned even closer to his cock. Ben stood on his tip toes as he reached an intense orgasm, his first long stream of cum rocketed from his cock and blasted Sue right in the cheek.

She let out a squeal of surprise and sat back on the floor. Ben moved over her and jacked the rest of his load allover her face and tits as she watched him dumbfounded. Ben’s cock felt so good he could hardly stand it. Cumming on his sister’s tits was turning him on even more. He kept pumping his cock, enjoying the feel of it swelling and growing bigger as he continued to jack off.

He looked down and saw that Sue’s skirt had ridden up as she fell back and her white panties were exposed. He could see a wet spot were her cunt had leaked. Ben realized that his sister was getting really turned on. She was playing with his sticky cum that coated her big, stiff nipples. Rubbing and teasing her nipples as she smeared his cum all over her small firm tits. He wondered if he could push her to do more for him.

“How many times can you do it?” Sue asked him breaking Ben out of his nasty line of thoughts.

“I go until my hand gets too tired to jack off with anymore. Usually six or seven times, something like that. By than my cock is so sensitive I can hardly stand to touch it. You look like you are getting pretty turned on yourself there,” Ben commented drawing her eye to her wet white panties.

Sue stood up quickly covering her underwear again. “Let’s just make this about you OK? I am showing you my tits and that is all you get. Just keep going, show me what you can do.”

“You are such a fucking slutty tease. I ought to stop right now unless you show me your pussy,” Ben threatened.

Sue blushed red but did not back down as she said, “You like my tits and I think you will keep going as long as you get to watch me play with my nipples.” Sue teased her right nipple as she said this, pulling the thick pink nub out away from her firm tits. “You liked cumming on my tits and I think you want to do it again, don’t you?”
