You don't have to

The room was filled with her moan and squelching sound coming from her little sister as he played with his fingers. The more she got excited, he moved his finger erratically touching the wall of her vagina, especially where she reacted more. He thrust his fingers while rotating inside her hole. Her one leg was raised to the maximum as to easy access to his fingers.

"Hmm… Yes… sweetie… there… little faster… Hann", she moan and demanded while she stroked his dick viciously. She was at her limit and kissing him everywhere at this time as he played with his pussy.

"Hann… I'm cumming… Hann", she moan and rolled her eyes while she let go of everything and her body twitched. Liquid started to flow from her pussy and made a small pool in the bed while she became even more slippery inside her vagina. While she was having an orgasm, he sighed and slowly withdrew his finger. He let her rest and laid beside her while trying to control his lust.

After resting for a couple of minutes, she looked at him while he was trying to control his lust. She smiled and slowly slid towards him. She immediately took him in her embrace while rubbing her body all over him.

"Thank you for doing this.", she whispered while kissing cheeks.

"No problem.", he got stunned and replied without thinking.

"But I want to help you too.", she said while touching his dick once again.

"You don't have to. Aren't you tired? Let's go sleep.", he got flustered and suggested.

"I'm not tired. I can help you.", she said while rubbing his dick even more.

"It's alright Mom. You are still recuperating from the operation. You'll hurt yourself.", he reasoned with her and patted her back.

"Sigh… Alright. Now cuddle with me. Next time, I'll definitely help you, ok?", she gave up and positioned herself in a spooning position.

"Okey, mom. Goodnight.", he said and cuddled with her from behind while he gave his one hand as a pillow for her and one hand around her belly. But she suddenly reached for his dick and place it between her thighs while clamping it. He was immediately startled.

"Don't worry. I won't put it in. I like to sleep this way.", she shamelessly replied while clenching her thigh hard.

"But… this is a little uncomfortable for me though.", he complained while his dick swelled again.

"If you feel uncomfortable then you can move your hips and cum.", she teased him while shaking her ass.

"That's not good Mom.", he complained.

"Sigh… you hate my old body that much… you hate to use my thighs too. Am I that unattractive to you?... sigh… Forget it. I'm sorry for asking you to do things that you hate so much.", she sobbed while curling up her body. His almost hazy mind almost exploded when he heard it again. He was doing everything to make her happy but if she felt sad then what about his effort? Isn't it just vain?

"Mom, it's not about your body. Your body is so hot and sexy that my things is almost exploding. You can feel that too, right? But… I don't wanna lose you. You are my dearest mom. How can I do that to you?... so I'm fighting with my lust.", he blurted out the things in his mind.

"What? Why would you lose me? Whatever you do, I'll always be your mom, even if I become my lover. So you don't have to hold back for me.", she said while turning her body toward him.

"But still…", he got caught off guard.

"How about this? If you don't hate my body then I'll use it to satisfy you without putting it inside me. How about that?", she sat on the bed and asked.

"I like your body but it's very hard to satisfy me.", he shook his head.

"Then watch me.", she directly sat on his waist and put his shaft between her pussy lips. She slowly started to grind his dick while moving her body. He was immediately hit by a different kind of pleasure and his dick swelled. His dick became longer and thicker for her to move easily. She instantly got even more and her love nectar poured on his shaft, making it slippery and easy to move for her. She move faster and faster while she moan and her breathing became erratic.

"Huff… How does it feel?... Hann", she asked while making a lewd face and smiling.

"Good. It feels good.", he replied while enjoying her ride.

"Hann… Me too… Hann… Don't you wanna fuck me?... Hann", she started to tease him while directly dropping her body and kissing him violently. She kept moving her body while pressuring his dick more and more. After the kiss, she again got her body up and continued to ride his shaft while putting his hand on her boobs.
