Extreme submission out of love by sis ( can be by mom or gf)
​
Bro and Sis live together, parents died in their childhood. Bro isnt employed. sis works as a torture slut ( lets assume that there is an underground profession like that with agencies running the business) to support both of them. There are 2 kinds of torture girls- regular n premium. For regular there are restrictions while for premium there are none. Sis a premium one.
She had a really hard session 10 days back and was in hospital. She should have been there for another 15 days but she takes early release and comes back as next day is bro's birthday and she couldn't leave him alone that day.
Some of the bro's friends have planned a party and had invited him and he was about to leave when the sis comes. On getting to know about the party she asks him to go even though she is badly injured and needs support. He leaves. On reaching there he finds that they have hired a regular torture slut. They all use her but none of them get satisfied due to restrictions and start looking for a premium but none are available
They ask about his sis and he tells tht she is injured. But they still insist, he tells them that if she has another session she wont survive and then he will be in a soup as she supports both of them. The thing is that the bro is highly selfish. He just acts as if he loves her but actually is just is after her money. One of the friends is a son of a big businessman and he offers a good job in his dad's company to him. The bro gets excited and loves the idea. He comes to his sis. Initially she doesnt agree as she is worried abt what will happen to him if she dies which is certain will happen. But when he tells about the offer she readily agrees for his benefit
