Later that night

At 6 p.m, John went into Emma's car. Tonight she wore a sexy black coat and a short skirt. Under that, she wore a half-transparent shirt, which clearly showed there was no bra.

"Wow, you look so gorgeous!"

"Thanks. Your compliment makes me happy."

Five minutes after the departure, Emma suddenly asked: "Are you getting a boner?"

John blushed a bit: "That... it's your fault!"

She nodded: "Yes, that's my fault. And I'll bear the responsibility."

She lifted her skirt and revealed her pussy.

John was surprised: "You want to have sex on the car?"

"Only if you want."

Of course John wanted. His fire of lust was ignited and it's not easy to be extinguished. He hugged Emma and gave her a French kiss, while she unzipped his pant as fast as lightning. The driver continued to drive as if he became blind and deaf about what happened on the rear.

John now had sex experience, so he easily guided his cock to her pussy, and then he sped up his thrusts until he fucked her hard. Emma responded with passion: Her tongue probed his mouth, while her inner muscles squeezed around his manhood. It became loose when he went in, and tight when he went out. John thrust harder and harder like it's the only thing that mattered in life.

After a long time, John finally reached the edge of the climax, but Emma stopped him:

"No, wait. Don't come just yet. I don't want to ruin the dress or the seat."

John had to use all his willpower to suppress the urge: "Then what should I do?"

"Can you take out the remote and press the blue button?"

He did as she said and found out the button has a line printed on it: "Semen Tank". He pressed it and oh God! What the button did was so incredible!

He felt that something suddenly embraced the tip of his cock, like a python swallowing a mouse. Then her inner side sucked him in like a vacuum, and John couldn't hold back anymore. Hot jets of his cum flooded Emma's cunt, triggered her orgasm. Then when he pulled out, he found that what swallowed his cock just now was her cervix, which immediately shut itself and closed the way to her uterus. Not a single drop was leaked out.

Emma smiled proudly: "This is a function I found in the guide. Your cum will be stored in my womb. Moreover, my body will keep the sperm alive for weeks. If I haven't been pregnant by now, then I would be in the next cycle when I ovulate."

After they both collapsed on the rear seats, John suddenly said: "Emma, I want you to try something interesting."

"Sure. What do you want me to do?"
