” He laughed“Hmm, any specific requests?”“For starters act really friendly if you know what I mean.” He winked “and from there I’ll just... give you some directions, just go along with it.”“Alright sounds good” I smiledAs the day went on I found myself getting hornier and hornier. I was just sitting on the sofa and my pussy was almost dripping wet!Finally around 5 the doorbell rang.I eagerly bounced up and went to go get it.I opened the door and flashed a wide smile“Hi guys!”There was a pauseAll. He groaned and moved his hips toward my face. I really took my time getting to know this cock. Each time I placed my lips around it, I took a little more in to my mouth. I was struggling with wanting to just suck it hard and fast. I was very patient and tried to be as good to him as he was to me. Eventually I took the whole thing (well, as much as I could) in to my mouth. When I finally got my mouth full, I held it there for a moment and savored the moment, as well as the flavor. . The first thing we did was stretching exercises. I watched my sister bend over and grab her ankle to a count of ten. She grabbed her other ankle after that. Then she got on her back with her feet toward me and lifted her ass way up off the mat into a bridge. Her moist pussy slit was right in front of me. Of course I got an erection. At first I was embarrassed but once I noticed that other guys in the class were sporting hard-ons too, I ignored it.The funny thing was that the instructor didn’t. She went to the switch board. I stopped her but she wanted to turn off the fan as she loved getting fucked while sweating. After few minutes I was fucking her and sweating. Believe me that it is a great feeling to fuck someone while sweating. We both were sweating like hell and the hotness increased when I cummed in her Pussy. My dick was as hot as sun and so was her pussy.I started to tit fuck her, our sweat acted as lubricant between her tits, cleavage and my dick, and my cum splashed all.
