Chapter 4

Joy’s pussy whipping went well, we got a lot of hits on our new web site. She is a natural and begs for more at just the right time. The comments think I’m a good dominant as well, which make my pussy wet. I’ve even taken to wearing tight leather in public and letting my dominant personality be seen more.

I found a guy online that could make bigger suction cups for Joy, they arrived yesterday in a big box. Joy was so excited she masturbated her big pussy on the box when I would not let her open it, I filmed the whole thing. It was so funny, her hands tied behind her back, her awkwardly rubbing up against the corner of the big box. We’re going to make a fortune from this slut.

The night of ‘Bimbo Modification’ (that’s what I called the video) I had Joy tied to the x frame with pussy and tits on display, she was blindfolded as well. I didn’t want her to see the new suction cups only to feel them. I took plenty of shots from all sides, the before and after pictures should leave no doubt that my sister is a bimbo slut.

“Joy you should see the size of these things, you’re gonna love it.” I teased the blind slut, opening the box and letting the camera watch her moan in anticipation.

After injecting the drug that makes it permanent I started with the boobs. I new she would cum when her pussy was touched and I wanted to tease her as much as possible. Her double Ds only filled two thirds of the giant cup, her boobs had plenty of room to grow.

With her breasts filling the cups to capacity, Joy moaned and begged for the pussy pump.

“Please slut, touch my pussy, I need to cum, hurry, please give me the pump.” Sis begged.

I was impressed with the pussy pump, it Looked like Joys pussy only bigger, it had a place for the clit to grow bigger as well.

“My god slut, you’re pussy is going to be huge after this thing gets done with you. You’re gonna have to sit like a guy to give that fat pussy some room. When you wear short-shorts you’re lips are gonna hang out.” I could see Joy getting excited with my teasing as the pump did it’s job.

After two hours of this I masturbated many times watching Joy cum. I whipped her a few times, tickled her to orgasm overload and made her pass out, vibrating her engorged clit through the transparent plastic cup.

After a day of recovery Joy couldn’t wait to show off at the adult video store. She’d been staring at herself in the mirror, trying on different slut uniforms. Joy wore white latex shorts, long enough her pussy lips wouldn’t spill out, but tight enough that even her large clit was clearly visible. She joked, how many guys would think she was a man with a small dick and a big set of balls. I told her with those gigantic boobs no one would think she was anything except a hot bimbo slut.

Another huge success, I wish I could have filmed it. After a few minutes of teasing the guys at the store, (Joy getting most of the attention of coarse) we were ushered to our favorite booth by the owner before the pervs started ripping our clothes off.

As soon as Joy’s crotch was on display her shorts were ripped off. (I love that part) Before I could get her tied to her side the pounding began. The guys kept commenting on her new fat wet pussy, I’m sure they would comment on her bimbo boobs slushing around if they could see them. Sure I got fucked a few times, but the best for me was escorting Joy through the store after her debauchery, with the transparent silk short-shorts I’d brought to replace the ones that were ripped from her body, showing the cum splattered all over her crotch and leaking out of her blown up cunt.

Instead of taking our usual cab ride home I decided to show this slut off, so we took the bus. We were in luck, there were four big black guys that look like gang members sitting in the back.
