"Vi, honey, you would literally die. You need to pace yourself here, even elite athletes have warmup and cooldown." Brenda said, patting Vi's stomach. "We're not going anywhere, we can fuck all the time. We don't have to do it all at once."

Vi turned to look at my wife, the haze of bliss clearing, her brain kicking in a little more, "Well…when you're done being concerned with my health…can I go down on Wendy for a little bit?"

"Vi, we're going to put you on the sidelines for a while. We don't want you hurting yourself." I smirked. "But, you can watch Brenda domme me as long as you promise not to masturbate until you've had at least twenty minutes for your pussy to cool down."

"I can be good…" Vi said, rolling over to sit up at the head of the bed. She reached around behind her back to take off the latex top she was still wearing, tossing it over to the other side of the room, her beautiful tits in full view, marked red where the ribbing and seams clung close to her body. "That's way too fucking hot to wear right now…" She shuffled the shorts off her legs, leaving her completely nude. "So…how am I going to watch if I can't masturbate?"

"Patiently, and carefully." I said.

"OK…so now what do I do? Where do you want me?" Vi said, her legs still open.

"Sit on the chair that Brenda was in." I indicated the luxurious padded chair that was next to our bed. "Just, please, Vi, I'm serious, don't masturbate for a while. I don't want you passing out." I said, tapping her thigh.

"I can behave…" Vi said, crawling to the end of the bed and then stepping onto the floor.

Brenda turned to me and stroked my hair. "Do you want a few moments of recovery time as well?"

"Yeah…let me get some water…just a quick drink." I said, standing up.

"Bring one for Vi too, dear…she's clearly lost a lot of fluids." She smiled at her. Vi was already in the chair, sitting comfortably with her legs spread apart, her pussy still open, her lips still glistening.

"You two are so mean…" Vi smiled back at us.

"Would you want us to be any other way?" Brenda said. She walked over to Vi and sat on her lap. Vi opened her thighs even further, but Brenda kept her own closed, resting on Vi's upper leg and not on her pussy. She leaned forward and gave Vi a little kiss. "Pace yourself, Vi, and we can build up your endurance. I know it sounds like fun to have a never-ending orgasm and just keep going, but it could really, seriously be bad for you."
