While Celestia hands went into her own pussy, Liam and Lilith also started feeling more and more lustful.
Both of them could feel their feelings and lust that they wanted to go deeper, that means they both wanted to have sex.
After some time of kissing, both moved back a little and Liam said "Then mom, should we do it?"
Lilith blushed and nodded her head while try to look at Celestia but she was surprised to find out that Celestia was fingering herself.
Then she couldn't help but smile and actually she knows that if she was in her place then she might do the same.
Now hearing that he wanted to do it. That not only mean sex but also pregnant.
This time her son not only wanted to make out that means having sex but also pregnant her with her child.
Now thinking about it again, it's taboo and if her so called husband found out then it would be a huge trouble.
