Little gym rat... Part 1 - Not only weights are useful

Mark met me in the gym of the fitness center as the physical trainer that was setup to help me learn new exercises and ensure the correct form. He is much older than me but very handsome in this tall dark way. His hair is very dark and he has a goatee with a very distinguished look. He showed me very correct exercises for the press, buttocks and back muscles. He touched my chest a little, a little bit of my magnificent form and held my ass with his palm in order to bend me into the correct position when performing useful, necessary exercises. After all, not only weights are useful. This sent tingles throughout my body which is constantly in heat anyway. He looked into my eyes and then looked at my lips as if he was going to offer intimate exercises for the mouth. I was very relaxed and beautiful, and I liked the caring attitude and attention to me from Mark. I am still just a student in school with so many schoolgirl fantasies running through my head. Mark's lustful eyes looking at me ignited another here and now. He has a pumped-up torso; his triceps, muscles of the thighs, biceps, buttocks, abdominal muscles kept extremely swollen, inflated forms in the correct proportions and sexually beckoned to meet a charming ‘innocent’ girl, and a powerful neck indicated that next to him he could feel like I am behind a stone wall. I was ready to give myself to such a handsome man as Mark and he undresses me constantly with his eyes. This naughty schoolgirl in tight short shorts and a sports top bends over seductively deliberately as he follows my curves, my shapely ass seemingly begging to see that bulge. For him to just grab me and take me right there. The gym is quite small and it is very late so most people have left but I come on off times often. I don’t like when a lot of people are around. I am just so fucking horny right now, trying to keep from seeping out giving myself away too easily. But I am confident this is going to be a very long workout.
 
As it gets quieter his hands become bolder on my body. He places a palm on my stomach sending lightning bolts striking me below. I tense up trying to hold back the flow building against the dam of walls clenched tight. My legs are smooth and strong, perhaps I can keep this dam from breaching too soon. The other hand he places on my lower back and fuck my mind is being blown from these insane desires to take his experienced cock inside me. I am like a piece of candy that just must be eaten. So young and innocent, but so fucking horny and needing to have my tight body tended to in every way. There are so many exercises I want him to show me. So many involve me riding that cock he is trying to hide from me so unsuccessfully. I want to reach out and touch it in awe of its building power over me. I know he can lift me so easily but there is no doubt I can be the most intense exercise he has ever had. I want to be that, writing a new exercise routine that involves doing so many reps on that cock until it becomes stronger than any muscle. Nothing like a tight grip to make it grow bigger, perhaps trying to break me but I will not break easily. As he shows me the proper form to do these squats I fall back a little so innocently my ass rubbing against his leg, and I feel his member jerk inside his pants. So, I stumble a little more, rubbing it harder and he knows I have to feel that but he tries to be stoic despite that eager cock. “I am so sorry, I lost my balance” but the look in my eyes says something entirely different. He is trying to contain his passion and failing. As he follows me with his eyes, every inch of me I run my hand down my torso and stomach until I brush over the mound below, curling one finger between my legs and rubbing ever so quickly making myself jump from the sensation. I feel like he is just going to grab me right here and now, taking down my shorts and shoving that rod of steel into me. He wants me to do some bench presses so I lay down on the bench. He is standing right behind my head and my eyes are looking back at his legs and bulge. Reaching up to take hold of the weights I rub his legs ever so innocently again. I imagine he is bench pressing me and he is trying to get me to focus but I am focused on something else.
