Chapter 166: Few hours before classes (3)**

Lilith felt happy hearing such a response from Lith. She said smiling to him, "yes, that's much better. Text us every day."

Lith nodded his head in understanding. He latched back onto his mother's nipples once again and started sucking milk. While doing so, he took out his phone from his ring and checked the time. It was currently 7:30am and there were still four and a half hours left for classes.

Realizing this, he kept the phone back in his ring and got up from his mother's side and went over to his sister's. He hugged her from behind and looking at his mother, he said with a smirk,

"There's still four and a half hours left. We can still have a bit of fun, don't you think so, mama?"

Lilith chuckled hearing it and said, "yes, of course."

Lucy remained silent about this and wrapped her arms around her mother's waist, burying her head in her mother's bosom.

Lilith had turned to her side, facing Lucy, when Lith went to her side. Currently, she is facing Lucy and Lith both.

Lith kissed Lucy's neck and moved his hand down towards her sweet honeypot. He inserted his middle and ring finger into her pussy and felt the warm softness of her insides. He moved it around a bit, checking for how wet she was, and after finding it was pretty wet, he removed his fingers and licked them clean.

He raised Lucy's leg up, causing her labias to be a bit separated and giving him easy access. He inserted his shaft in her, slowly, so as to not cause any pain to her.

Lucy felt Lith's dick slowly penetrate her pussy. She could tell he was putting it slowly so as not to hurt her, and she was comforted by the fact that he was so meticulous. However, she felt that going this slowly was a waste of time, so she lowered her hips and took Lith's shaft into her all at once.

"Mhmm~"

Lucy moaned as she felt a mix of pain and pleasure due to having it fully inside her.

Lith groaned a little as he felt his sister's tightness and felt pleasure. He was amused a split second later, knowing what his sister had just done. He was taking it slowly because he didn't want to hurt her, but she went ahead and took it all in, despite the fact that it caused pain.

Lith was starting to think that his sister was really a 'M' now. Last time when they did it together, he thought she must've asked him to move despite the pain because she loved him and this much pain didn't bother her. However, now he was having some other thoughts.

He thrust his hips slowly back and forth while enjoying her inner walls wrapping around his shaft. He then bent his head forward and whispered in her ear,

"Big sis, are you perhaps... a 'M'?"

Lucy blushed hearing it and tried to bury her face deeper into her mother's bosom. While in such a position, she said in a suppressed voice,

"N-no."

Lilith and Lith both chuckled as they watched Lucy's reaction. They both had a pretty good idea that she was who they thought she was. However, they didn't call her out on it.

To confirm his guess further, Lith, who was fucking Lucy's pussy from behind, spanked her ass with moderate strength.

"Oomff~"

Lucy released a muffled moan while her body jerked in surprise and her insides tightened up due to it, making Lith amazed by the pleasure he felt due to it tightening.

It was pretty much confirmed by Lith now that Lucy indeed liked the pain and was definitely a masochist. He smiled after realizing this and once again whispered in her ear,

"So big sis is indeed a 'M'."

When Lucy heard this, her cheeks and ears turned red. Lith received no response from her as she lacked the courage to do so, and would never admit that she enjoyed it. She refused to accept it because she thought it was too embarrassing. There was no other reasoning.

Lith and Lilith both chuckled seeing her lack of response. Lilith was having fun looking at these little gimmicks of her children, so she didn't interrupt them and let them continue so that she could see more of it.

After this small talk, Lith continued to thrust his shaft inside her and spread her pussy. He reached deep enough to touch her womb and every time it would hit, Lucy would release a moan.

Lilith in the meanwhile, had her chin rested on top of Lucy's head and was caressing her back as Lith pounded her. Lucy was simply enjoying it as she was the only person among the three who wasn't doing anything.

A while later, Lith could feel that he was halfway there to cumming and due to this, he decided to change positions as he wanted to have his sister cum at the same time too.

While his dick was still inside Lucy's pussy, Lith stood up and positioned himself in a missionary manner and continued thrusted in her. As he got into this position, Lucy's legs were spread wide apart, and her pink lips, which were spread open due to Lith's shaft and her big breasts, aroused Lith even more.

Lith bent down while continuing to thrust and brought his own face closer to hers, he said, "let me see your beautiful face, big sis."

Lucy felt embarrassed and wanted to deny him, but she didn't. The reason for this was because they were already doing something very embarrassing, and the fact that she enjoyed having her pussy pounded by her own brother's cock made it even more shameful and embarrassing.

This thought came to her almost instantly, and it was only then that she realized she was already doing things that were embarrassing and shameful, and that her brother asking to look at her face was nothing compared to these. As he continued to pound her, she turned and looked at him.

Lith looked at his sister's beautiful face, that now had a tinge of red around her cheeks and ears. This, along with her half closed eyes made her look so alluring that he got even more turned on than before.

Looking at her, he gave a peck on her lips and said with a smile, "Big sis, you were about to commit a sin, you know? Trying to hide such a beautiful and pretty face is sinful. Thankfully, I asked you quickly and didn't let you sin, hehe."
