Kim's turn

It was instantaneous bliss as Kim sat on my borrowed dick. I've fingered her and ever eaten her out a few times before but having a sensitive part of me this deep inside my beloved sister was a different level. Her pussy radiated a gooey warmth as it hugged Ken's dick. I reached up and began to grope Kim's breasts, my new bigger hands allowing me to grab a lot more than I could usually although they still were too big for my grip. I teased her nipples as we both moaned loudly, the sound of Kim's sweet moans turning me on even further.

It wasn't long before, "Get off I'm cumming!" I shout in a voice that would probably embarrass Ken had he heard it. Moving remarkably quick, Kim hopped off my dick and replaced her pussy with her mouth as she took my load down her throat.

"Hmmph, you're getting better at this. You lasted 6 seconds longer than last time," Cass chided. I was completely spent despite neither Kim nor Cass actually climaxing themselves.

"I think I'm just gonna let him go back to sleep, hell I might pass out too," I say as I use Kim's panties to wipe my dick off (to which she had no objections) and pulled his boxers back on. I crawl back into the sleeping position he was in before pulling the covers back on and hopping out of his body.

I immediately felt rejuvenated, as if I did not just blow 3 or 4 consecutive loads, as the three of us, two of which were still completely naked, shuffled out of the room to let him rest.
