The next day I rushed to the gym at the same time but was disappointed not see her there. Almost an hour had passed and no sight of Laura. However a few minutes later she came in walking through the door in tight black yoga pants and crop top. She walked by me and said I am so glad to see you here today, winked and walked to the locker room. I was pretty much done working out but I now I had to stay so I went over to the tread mills. Laura walked out of the locker room sat right on the bike in front of me. After doing a quick 5 min warm up she got off and started stretching. Her yoga pants were thin and every time she bent over I could see the bright pink thong she was wearing underneath. The gym was a little more crowded today and I could tell the guy running next to me was enjoying the show too. Laura got back on the bike but this time she leaned forward so I could see her thong and after a few minutes her pants started riding down a bit and her whale tail was in full display. I could have run for hours with that view. She eventually stopped and asked me if I could help her stretch hamstrings. I don’t know shit about stretching but of course I said I’d help. We went over to the ab/stretching corner of the gym. The corner was empty minus the MILF I caught in the locker room a few weeks ago. Laura said she was in a lot of pain and asked me grab her heel and push to back towards her head as she lay flat on her back and I was on my knees. To my surprised she was extremely flexible and her leg stretched so far back her pussy and dick were practically touching. We held this position for 30 secs switched legs and did it 3 more times. My cock was rock hard again and I could feel her pressing her hips into me. It didn’t help that she moaned so sensually ever time I stretched her leg back. Even the MILF was taking glances at her when she moaned, it must have looked like we were fucking. Eventually we stopped and she started stretching on her own and asked me to join her. Of course she started by doing the downward facing dog. Her whale tail was in full display again. To my surprise she asked me to go in front of her and help push her shoulders down. It didn’t make a lot of sense but I wasn’t going to say no. I start pressing her shoulders down. My dick is rock hard and practically resting on her head at this point. She moaned in pleasure and all of a sudden I feel something wet around my cock. She put me in her mouth through my shorts. I was so startled I almost jumped up, I couldn’t believe she was doing that with the MILF only a few feet away and several other people walking by. She started moving her head back and forth rubbing my dick all over and then with her teeth she pulled my waist band down releasing my 8” cock and shoved it in her mouth immediately and started sucking me off. It only lasted about 10 seconds before she stopped and got up. I scrambled to get my dick in my shorts, the MILF definitely saw what just happened, she had a look of excitement on her face and I could see her pierced nipples poking through her sports bra. Laura looked at me with a huge grin and told me to follow her. She led me to the sauna and we put up the sign saying “full capacity” on the door. She looked at me and said “you really liked my thong today didn’t you?”. I nodded and said I couldn’t believe she just gave me head. She laughed and said it was nothing, and she could tell I needed it from the constant tent in my pants. She stripped down until she was only wearing her thong. I followed but took my boxers off, without skipping a beat Laura got on her knees in front of me and started licking my cock up and down while looking at me. She stuck her tongue out and slapped my cock against it. “You have such a beautiful cock I haven’t been able to stop thinking about it since I felt it against my ass yesterday.” Laura then put my entire cock in her mouth until she gagged pulled it out ,spit on it, started going back and forth fast now while she grabbed the base twirled her hand. She seemed to love sucking my cock, she was so enthusiastic and would purposely make her self choke on it until her throat made a noise that i couldn't handle anymore. I was in heaven. A few seconds later I was about to explode but she stopped and said “fuck me like a slut". I picked her up off the floor put her on the bench, pulled her thong down to her ankles and started fucking her doggy style. She moaned asking me for more and not to stop. I spanked her fat white ass and she loved it. I started fucking her harder while I grabbed her ponytail. She was loving every second of it. I kept slapping her ass cheeks until they were red, her pussy to get wetter the more i slapped her, it was such a turn on. Right as I was about to cum she got off my dick, got on her knees and stuck her tongue out. I drenched her face with cum until it was dripping from her chin down to her tits. She had a smile bigger than I had ever seen before. She scooped up the cum from her chin and put it in her mouth. She put on her clothes without wiping off the rest and we left the sauna only to see two girls waiting for us to be done. From the look on their faces they must have heard us or seen some of the cum left on Laura's face. Laura and both cracked up and left. She then kissed me on the cheek and said same time tomorrow?
