Step Brother's Revenge

Chapter 4
Sheila Comes Home

Chapter Description: Sheila the Step-Sister comes home from College and Sandy comes over for an eventful visit. Sexual Content both consensual and non consensual.

Sheila drove her Chevy Chevette into our U shaped driveway. She started unpacking the trunk and stacking things on the porch. She was dejected. She hadn’t done very well in school. In fact she failed to carry a single class. She thought she was bright. Her mother Charlotte had always said so. But after three months of partying she hadn’t gotten anywhere but third base.

Now her boyfriends had moved on and she was stuck at home. Still it wasn’t so bad. Sheila had started in the second semester. So flunking out only meant starting her summer early. The only cost was making sure the house didn’t burn down while her mom and Tom were away on their second honeymoon, which was looking like the whole summer.

Sheila had been given the master bedroom while “the folks” were gone. I was relieved because that would give the upper half of the house to us. Jimmy could continue to plunge further and further into humiliation up there. Still Sheila would eventually find out and then what? Jimmy had suggested as much. In fact I got the suspicion that he was holding out to that as his rescue.

Sheila found a note from her mom, Charlotte, suggesting things will only get better and a positive thinking CD under it. It was actually a plant by me in the hopes of keeping Sheila out of my hair. It had a basic suggestion on it to defer to my decisions or desires and to not interfere with Jimmy.

Sheila had always been nice to me so I didn’t want to do anything to her. I just needed her to stay out of the way.

When Jimmy looked out of the window and saw Sheila’s Car pull up he was grinning from ear to ear. He was wearing a diaper. It was part of his five hours now of punishment time. It was the fourth day and he had already managed to wet himself twice. The subliminal tapes and suggestions were working wonders too. Not only was I able to get many of Christy’s babifications reinforced for non punishment time but with a few words I could induce a baby state with Jimmy fully aware of what he was doing (like behind a glass wall). He felt and experienced the embarrassment but was powerless to be anything other then what he was, “An itty bitty baby.”

Christy was beginning to take on a kind of motherly role. Still she was still exploring her sexuality and having Jimmy under her control meant she could explore his body and hers. This proved to be humorous because his manhood was in decline. But there was a trigger though. If he would be extremely embarrassed by it then his manhood would come raging to life.

Christy would discover this two weeks from now. She decided to take Jimmy on an “outing” to the park (3 AM) in full baby mode. When she changed his shitty diaper on the “Merry-Go-Round” he was overcome. Controlled and exposed in utter humiliation he sports a raging hard on. In response Christy pops a large pacifier into his mouth and takes his manhood. When she was done riding the merry-go-round with him he was confused. He had been infantile and had been subdued by her. Not being able to respond as he would desire too. He was left to flail about as she had mounted him. Seeing as this was his first time the emotions and the orgasm proved so emasculating it set the stage for him to be subdued by women for a long time to come.

Jimmy blinked and headed for the door. He had waited for this moment when Sheila would set things right. Christy looked at him and reminded him his time was not up. When he resisted she reminded him about the locked file and asked him if he wanted her to give her friend the password? Jimmy slinked back to playing with his toys.

When Jimmy was done with his punishment he was allowed to get changed for the day and go see his sister. He didn’t say anything (he knew better). At first Sheila coming home was our problem but now it was his as well. If he stopped living up to his sentence Christy would be justified in humiliating him by exposing his secret.

Sheila was easing into her new life. She unpacked the car first and then set up her new room. The absence of her brother was a blessing at first but later became a curiosity. Christy hears some strange sounds and smells but didn’t investigate. It was past noon before she finally saw Jimmy and he seemed different. Maybe it was just the last three months away. Maybe he had just grown or changed some.

Jimmy seemed to be a little more pensive, afraid to say the wrong thing. He was also kinder to Stanley and Christy. This confused Sheila but she always though Jimmy needed to be nicer. She had corrected him a few times but Charlotte had told her not to squash his individual expression. She thought he had been a brat and bully but didn’t want to fight her Mom. Still she was happy that he was now changing for the better.

Everything seemed to be alright…except she found some clothes in Christy’s closet she couldn’t explain and most of them would disappear for longer and longer periods of time. Then there was that time at Dinner that Jimmy suddenly got up from the table and ran to the bathroom. Sheila could have sworn she saw him wet himself. Then there was another time late at night. Right before bedtime she could have sworn he was wearing a diaper and didn’t Jimmy smell different?

It went this way for about a week. Then Sheila announced that she was going to the Mall at first Jimmy had wanted to go but in the end it became a girls night thing. Jimmy had other things to do. Sandy had been bothering us to “come over” when she could “see” Jimmy and “talk” about their “pictures.” I let Jimmy know that his “girlfriend” was probably going to insist on a more intimate visit.

The girls were gone thirty minutes before I had Jimmy get ready. With a few suggestions he was ready for the visit. Sandy came in. She was mesmerized by this slobbering crawling baby that use to be her boyfriend.

"Can you watch him for a little bit? I need to go do chores."

"Okay. What do I do?"

"Whatever, he’s being punished for wetting the bed. He got so bad he has to be a baby 6 hours a day."

"Okay ..." She said absent mindedly rubbing herself. "So he has too ..."

"Don’t worry about it. He’ll be good. Just play with him how you like. Change his diaper as need be and don’t turn off the CD player it will make sure he stays calm while I am gone."

With that I pressed play and left the room. One hour later I came back and Sandy was bare bottom spanking the baby for what he tried to do a few weeks ago. Babies shouldn’t try to get in big girls panties. All the while the CD was playing. She adjusted herself and left the blubbering brat to me. I re-diapered him gave him a bottle and let him roll around on the floor.

Sandy recognized control when she saw it but couldn’t put words to what it was called. Her mind was hazy around the word. She walked over to me adjusting her pants.

"Oh thanks!" she said as I unzipped her pants. Jimmy just starred from behind the mental wall I put up. She turned her back to me and I pulled her pants down her long legs revealing her purple lace panties. Sandy didn’t bat an eye lid but acted as if I had only taken a coat. She turned and started unbuttoning her shirt. Turning again toward Jimmy she flashed him with her long full melons held firmly in her bra. I helped her remove her shirt.

Her comfort level after our studying and the study helps (math tables done by audio ECT ...) with a subliminal message behind it and the two hours of reinforcement CD really was working. Many of her inhibitions were down. It was just like getting her drunk. The panties were next but as I helped her pull her panties down she saw me adjust uncomfortably with the sudden bulge in my pants and decided to return the favor. Unzipping my pants and pulling down the pants and underwear she gasped. Then she took me into her mouth acting out a fantasy she had developed by watching a porno with Jimmy.

Sandy unbuttoned her bra letting her melons free as she continued to suck. Making me sit down on the coach she slowly began to mount me. She brought my head down the course of her body. She dragged the head of my dick down from her mouth through her long breasts down her belly and into her snatch. She pushed and she grunted but it would only go so far. She was a virgin. But rubbing her breast as she continued to jack hammer my cock against the wall made the wall break with a gasp.

As I played with her breasts I approached climax. She had reached around and was playing with her butt hole.

"I’m going to cum." I said.

"Not yet!" She said pulling herself off. I want to lose my virginity twice in one day. She then turned around and kneeled on the floor three feet away from Jim dangling her breast before him and exposing her butt hole to me.

"Now" she said

I slowly worked my dick into her anis. Sandy became excited looking at Jimmy staring in amazement. He was a baby in so many ways but his body still reacted like a man’s. He could not respond as he wanted but his diaper became uncomfortable. He adjusted it and his penis poked out the top. She knew he would be in pain later but it served him right. He shouldn’t have pushed her too far. Now he would pay. By watching all this and knowing he would never be first.

She began to jackhammer on my cock like a porn video rubbing her clit, fully exposing herself to Jimmy as she lost the last of her virginity. We both came at roughly the same time. That’s when I noticed a small stream of blood coming from her anis.

Jimmy came in his diaper on command. Sandy talked to him like a baby as she changed his diaper and then we sent him to his room. I spoke nicely to him (bringing him up to about twelve years of age) and then sent him to his room to play in his diaper. I Knew that I would find him later crying and wetting himself again.

Sandy was mesmerized by all this but took it in stride. She had a word for this but she couldn’t get it to come out. Sandy’s love for sex that involved someone’s humiliation steadily increased that Sumer until we parted ways.

I was told Sandy later got a job as a Cashier at the Piggly Wiggly where an assistant Manager “fell in love” with her. She convinced him to go through her checkout line in nothing but a wet diaper. She changed him right on the conveyer belt and then fucked his brains out. Everything was alright until the managers checked the security tape. They dismissed the both of them. Sandy’s mother was informed which earned her quite a few counseling hours and the Assistant Manager received manager received even more hours of “diaper therapy” mandated by a court psychologist.

A copy of the security tape was later leaked to a porn site and Sandy has been working since.

We cleaned up and Sandy went home. We thought we had removed all the evidence. I didn’t know there was a digital recorder under the couch. How was I to know?
