We have nothing planned for the day, so we take our time getting going. I'm already up and moving around, while he lounges on the bed, playing with hi... phone.I'm still feeling a little sore from my previous day’s workout, so I set up my yoga mat and began to stretch out my overused muscles. I warm up pretty quickly when I start moving, so I dress lightly, wearing only a t-shirt with a lacy bra and panty set underneath.I close my eyes and take a few deep breaths. Then I begin.When I stretch up. He mentioned he used to be a heavy drinker, but quit, and never liked smoking weed. I asked him what else he still did. He said he worked and that's about it. He didn't bite.Later I brought up the nearby bookstores that were shut down some years ago. He knew all about a few I had been to back in the day. I mentioned gloryhole booths and bluntly asked him if he'd ever been fucked in a gloryhole booth before and he said no but he'd had his dick sucked before.I laid it right on the line and asked. “Good girl… you are such slut, babe… love your tongue right there”She hissed as she started to grind her cunt into my mouth. She then moved her hips back and forth, trying to meet my tongue, as she moaned and cried in ecstasy. The bitch was really hot…Soon I felt my own heat inside my pussy and knew it was making me wet and horny. I put my hand to my crotch and slipped my fingers inside the yoga pants. I went directly to my swollen clit and massaged it until I reached my own climax. I stopped. She showed it to me, then swallowed the whole lot in one go."Don't worry, I was the one that went down on you. I wouldn't have done it if I didn't expect a wad of cum to end up in my mouth."Wow, my sister was turning out to be rather slutty. She engulfed my cock between her lips again and proceeded to lick me clean."Perhaps we should keep that to ourselves, eh?" she said when she was done and stood back up."Sounds like a good idea." I said. I then redressed and left the bathroom as Kara started.
