It has been days since Taylor and I have had sex. We were both horny as hell. Taylor pushes me onto my back and mount me cowgirl style. As she sits up...ight working her hips forward and backward, rubbing our pubic bones together, I squeeze and fondle her breast. Taylor’s pace picks up and I can tell by the contractions of her vagina that she is on the verge of her first orgasm. Suddenly I hear a loud shriek, followed by “Oh my God!” I look up and see Karen standing in the doorway with her hand. Jab usne darwaza khola toh dekha mene ki meri maa udr andar nangi khadi fir woh andar jaake darwaza band kr dia aise chaaron b ek ek krke andar chale gaye unka session sab khatam hogaya tha.Toh me apne bed me jaake firse so gaya dekha fir chupke se dekha ki woh chaaron ladke aagaye fir thode der k baad mom b face clean krke aarhi thi mom ne unko dekhke smile dia aur window seat me baith gayi fir ek meri mom k baje me baith gaya fir sab baat kr rhe the thode der k baad raat hogayi aur fir mom ne. My cum drenched the gusset and mixed with the other seminal fluids already on her panties. Oh shit! I couldn’t believe how much cum I had released.It was a few minutes before I sat back down into the desk chair and was able to grab my breath. My cock was still standing at attention. I looked around and gathered my wits. I gathered my composure and pulled up my underwear and my jeans. I looked around to make sure I didn’t spew any stray cum on the desk or the magazine.Satisfied that I had not. That's what keeps my butt in the nice shape you like so well," she giggled. "It's a class that has a very uneven attendance. One week every bike will have a rider and the next week only two people show up. It's weird. But the instructor doesn't even notice. She has her workout routine set and she follows it whether we there are two or twenty. I'm not even sure she ever looks up to see how many people there are. She just shouts out instructions for changing gears and taking hills as she buckles.
