Time for some grinding

You couldn't be happier as Jennifer lowered into your lap once more, this time with only her panties and your underwear between your naked bodies. Her plump ass pressed against your hard cock and you couldn't hold back a small groan as your head rolled back for a brief second. Marcus looked over, clearly surprised by your groan as he saw his wife in your lap, but still didn't seem too bothered.

That would change though, you were going to make sure of it.

You leaned forward slightly and moved a hand up, brushing aside some of Jennifer's long hair and pressing your lips close against her ear.

"Grind that amazing ass against my cock," you whispered. Much like your previous commands, it took a few seconds as she fought against your words. Then slowly you felt her ass begin to move against your crotch. One of her hands moved down to your bare thigh, helping to steady her as she worked herself against you.

Marcus looked over, clearly confused and growing more concerned as he watched his wife begin to move and grind against you. Sure, you had made him okay with your earlier compliment and the idea of his wife cuddling on the couch with you, but this was completely different. Now his wife was in her underwear and actively grinding herself against another man's cock, and he had to be completely aware of how turned on you are from you standing up and removing your pants just a moment before. At this point though, you didn't care if he was concerned. His objections and worry over losing his wife were inconsequential to you with how much power you were starting to hold over Jennifer.

"Finish your beer, then go get us both another," you whispered. Jennifer obediently pressed the bottle to her lips and chugged down the last third of her beer, grabbing your empty bottle from the table.

"Gotta get us refills," she said, easing to her feet. Your eyes were glued on her ass, swaying with each step as she walked towards the kitchen.

As Jennifer walked from the room, you left your legs spread wide. Your cock was sticking straight up, obnoxiously hard and obvious as it strained against your underwear, and you knew that Marcus would easily be able to see it if he looked over at you.

"Fuck, I love how Jennifer has really loosened up around me! It's great getting closer with your wife man," you said to Marcus, with no doubt a gargantuan smile on your face as you rubbed what was happening in his face.

"Yeah it's, uhh..." he said, taking a drink of his beer before he continued.

"It's not really normal though, for you guys to be that close," he said just as Jennifer walked back in. That was probably the best way he could put it without accusing anyone of anything or being too confrontational, not that his concerns really mattered anymore of course.

"This is totally normal, right Jennifer? Tell him it's fine, we're just getting closer to each other," you said. Your words hung in the air for a brief second as Jennifer walked straight towards you.

"Oh absolutely, Dustin is right. This is totally normal, and you're the one that said you wanted us to be closer," Jennifer said as she walked back over to you. Holding out your beer to you with a smile.

"Thanks for the beer babe," you said as you took it, twisting the cap off and taking a swig as you thought of what to do next.
