Rubbing

"O-Oscar Wh- why do we have to rub?" Susan asked, her breathing started becoming heavy, she was so close to Oscar's face, and her tits smashed on his chest also didn't help in making her calm.

"Oh, you know how we rub stone to make a fire? In the jungle right?" Oscar made up an excuse, this was a pretty decent excuse too.

"Oh, I-I think I'm warm enough," Susan said, trying to get away, her body was almost melting with Oscar's continuous thrusting and his hot cock lodged between her pussy lips was making the situation weird.

She was not sure if this had to be like this or if it was all in her empty head. Oscar didn't stop, he kept on moving his hips.

"I think it's still not working," Oscar said, grabbing Susan's ass and started moving her pussy against his cock, rubbing her pussy and ass cheeks on his cock, making Susan groan a little.

"Oscar, I- I- I- don't think we should be doing this," Susan said, she felt something odd and strange, her body was telling her something was not right, but her mind was getting blanked by her trust in the sweet sweet brother in law of hers.

"Shh, just relax and feel," Oscar said, he had an evil grin on his face, he was so close to shoving his dick inside her, but he didn't want to ruin everything so early, he had to play the long game. He kept on rubbing his cock, reaching for the orgasm, that first victory he was about to get for tricking this gullible fiance of his brother.

Susan didn't know what was happening, she felt so strange, her body was heating up, and she felt a tingling sensation in her tummy, almost like she needed to pee but her bladder wasn't empty, it was something else.

"Oh, fuck," Oscar groaned, he grabbed Susan's ass and started moving her faster on his cock, his precum was making a natural option for all that rubbing he was doing, making Susan's pussy juice flow out of her and drop bit by bit on the sheets, where Gary would have been doing this if he was not stuck.

"Oscar, I- I think I'm gonna-" Susan couldn't finish her sentence, she moaned loudly and started wriggling her body.

"Oh, Fuck," Oscar groaned, his cum shot out of his cock and onto the sheets, Susan's legs were almost about to give in and her body was sweating, Oscar was just lying there, smiling, looking at the dumb goddess lying in front of him, cumming on his cock.

"See, We are sweating, if we rub each other like this, no one will get cold," Oscar said, staring at Susan's huge tits going up and down with her heavy breathing.

"Yeah, you are right Oscar, you are such a good brother," Susan said, smiling, not even trying to cover herself.

"Don't worry, I have a lot to teach you, we should sleep for today," Oscar said, his eyes glued on Susan's boobs, he was still horny but he couldn't go again.

"Huh? Like we have more?" Susan asked,

"Yeah, we need a lot more practice, we have only seven days after all," Oscar said, he wanted her to be **** for his cock, make her crave it.

"Oh, Okay then," Susan said, she was so confused about what was going on, what she had just done and how she was feeling now. She felt so hot, sweaty and weak.

"Good, now let's sleep," Oscar said,

"Yes," Susan said, she was just following what her brother-in-law said. She turned away from Oscar and lay on the bed.

Oscar was still looking at her, her boobs were bouncing a little with every move, his cock was still rock hard and the smell of his cum was still in the air.
