A happy mother of three

Having three stepsons sounds like a lot of work, but Sarah's were wonderful kids: aged 18, 19, and 22, they all behaved perfectly, and even their father didn't know why.

"Hey, mommy!" The youngest one said, approaching as Sarah was reading. She had asked them to call her mommy when they wanted her to do naughty things. "I've finished all my homework already."

"Wonderful, my boy. You can do it anywhere you like."

Their favorite place was her large breasts, although sometimes they chose her face, or her mouth, and a few times they said her hair. She was happy to oblige, as her stepsons were growing to be wonderful people. They had a rule, though: no touching. Sarah could not grab their big cocks, nor the sons could grope their stepmom. It was a deal so nobody felt she was cheating on her husband. A... Technicality. Only the tip of their cocks could touch Sarah's skin, and only right as they came.

The youngest son started jerking off hard. Sarah always wore skimpy clothes, to help her sons appreciate her body more. This time, Sarah pulled her cleavage down, showing even more of her big bosom. A couple of minutes later, the son ejaculated, shooting a very large load on her and covering her breasts.

"Good boy" she said, and kissed her son's cheek.

Some minutes later, the middle son approached her.

"Mommy, all the laundry is done, and the bathrooms are sparkling clean!"

"Great job, son! Where would you like it?"

"On your face."

He did like his brother, and jerked his cock hard. Sarah loved the wet, fapping sound of her stepsons' big dicks as they masturbated. It made her doubt if they actually needed that rule. The son put his cock next to Sarah's cheek and shot an even bigger load across her face. Some flowed into her mouth, some flowed onto her breasts.

"So good, sweetie."

Then the oldest son approached her.

"I've come from grocery shopping, mom, and everything is in the fridge. I also bought you this!"

He gave her a black choker with a silver heart. She put it on, on top of a streak of her own son's semen.

"Where would you like to?"

"In your mouth."

The son started fapping. Not only was he the oldest, but also had the biggest cock and the largest loads. He took several minutes, but he shot abundantly as he pressed his dick against her mom's lips, and into her open mouth. She swallowed as much as she could, it was so much a lot of it still escaped her mouth and ended on her breasts as well.

"As tasty as usual, my boy!"

Then he left. She read a little, but she ended up going to the bathroom to masturbate and take a shower. She didn't want her husband to find her covered in her stepsons' semen.
