The following night was warm, and I slept with only my boxers on. Early morning I stayed in my underwear and looked in the sky. The planets changed their position slightly but were still impressive.
I aimed the telescope at Mara's window and saw her upper body. Unlike before, the light in her room was brighter and this time came from her side. Her transparent nighty revealed her gorgeous tits and dark nipples. Every couple of seconds her arms moved, and her mammaries swayed lightly under the loose material. I couldn't stop ogling her terrific tits. Venus and Mars lost their luster in comparison to these breath-taking twin peaks...
After 10 minutes of nonstop ogling her chest, I directed the telescope again at the sky for a short time before lowering it one more time at Mara's body.
About a minute later, Mara's face moved from the sky toward my house. I knew that without a magnifying device, she wouldn't be able to tell I aimed my telescope at her and continued observing her. With a smile, she moved slowly from her window, and returned to bed.
The following late night was the same. Mars and Venus were now further apart, yet still easily noticeable. I shifted the telescope to her house. Mara was in her window with her room fully lighted. I noticed her hand moving down fast. I couldn't care about her hand because her top was now exposed. Yes, she was topless!
I was puzzled; it was quite a warm night, but being topless was unexpected. The lens concentrated on her chest, and my eyes fixed on Mara's ample orbs. Her nipples looked pointy and hard. The sight was no longer just exciting. It became erotic and... tempting. My pecker expanded and extended in my boxers, and my palm caressed it. I was no longer thinking about the planets. Mara's naked chest filled my brain with naughty thoughts.
I aimed the instrument slightly higher and watched her face. Her eyes were shut, her lips parted somewhat, and her facial expression suggested extreme pleasure. Was the celestial view arousing her? It was nice, and even inspiring, but arousing?!...
As my mind was busy with these thoughts, my hand continued bobbing my tool and not long after, I ejaculated into the tissue I had.
My last girlfriend and I separated 7 months earlier. Until that night, I was jacking off on average twice a week, mostly fantasizing about sexual scenarios I had with my prior girlfriends. Doing it now while thinking about my current student was frightening and... rather exciting. I felt like a pervert, prying on Mara's privacy without consent, but I couldn't stop myself. The only 'consolation' was that Mars and Venus wouldn't be easily seen again for a few months, so she would no longer appear in her window. It was a relieving thought but a sad one too.
...
On Tuesday, Mara came for another physics lesson. As before, when I let her in, she smiled nicely. The only difference: This time instead of wearing pants, she had on a short skirt that exposed her shapely legs.
I brought coffee and cookies, and we began concentrating on physics. Once again Mara displayed adequate comprehension of thermodynamics, and we moved to electromagnetism. I noticed that in that subject, she missed some concepts and I explained them in 2 different ways. She got everything and grinned, "Thank you, Leon. You are a real treasure. What would I do without you?"
"You would read about it or use another tutor."
"I don't think you understand: There are many volunteers to tutor students like me, and some of them know the material very well. However, I haven't met somebody who can explain everything in simple terms quite like you."
I joked, "I get what you are saying. It means that next time, I should expect another treat containing chocolate."
She gazed at me and mumbled, "I'll do better than that."
I didn't want to push my luck and elected to leave the subject. When she was by the door, Mara turned to me, "Since you like astronomy, I am sure you know The Perseids will be best seen at the predawn hours. I love watching falling stars and will watch them starting 5 am until the sun comes up."
"I knew about the meteor shower. I didn't mention it because I thought after 3 interrupted nights, you wanted to have a good, long night's sleep."
"Leon, I chose to graduate in astronomy. This is my obsession and I do not wish to miss the opportunity to watch the best meteor shower of the year."
I caressed her arm and said, "I admire your dedication. See you Thursday evening."
...
I woke up at 4:45 am, made myself hot coffee and sat to watch the stars. I observed 3 'falling stars' in the first 5 minutes. Then I pointed the telescope toward Mara's window. I couldn't believe my eyes; she sat on the window frame with one leg outside, wearing only panties! The light source in her room was in front of her body, illuminating her chest. I ogled her magnificent breasts in profile. As Mara stared at the sky, I saw her holding a binocular in her hand. It didn't make sense: When attempting to get a better view of Venus and Mars, binoculars may help. But with meteor showers, the device is useless, because we can't tell exactly where in the sky the falling star will appear... I continued aiming at her sexy top and followed the mild bounce of her tits. Her nipples looked tiny and very stiff.
My hand crept to my erect cock, and I began masturbating. As my hand was working my pole, I directed the telescope at Mara's face. To my surprise, I saw her looking through her binoculars straight at me! When the lens was focused on her face, she smiled broadly and waved at me... I was shocked, and in an instance, aimed the telescope at the sky again. I stayed another 5 minutes, pretending to glance at the sky and then left the window.
I was confused. Yes, I behaved like a low-life voyeur, trying to get glimpses of Mara's beautiful breasts. However, she didn't seem like she was offended watching me ogle her. Why was she topless in the first place? Was she trying to tempt me? I had many questions and no clear answers. I was scared about our next meeting, the following day.
...
Mara rang the bell at 6 pm. I let her in, not knowing how to behave. She brought me a small bag with Belgian pralines.
I stuttered, "Maara, coffee as uusual?"
She gave me a million-dollar smile, "Yes, please."
As I was making the coffee, she moved behind me and whispered, "Leon, did you enjoy the show?"
My legs shook, and I responded, "Yes. The Perseids always give a perfect show."
She came closer, "And the other show?..."
"Mara, what are you doing?"
"Leon, stop pretending. I saw you aiming your telescope at my window the first night. When I moved away from the window, I noticed in the mirror that it was partially transparent. I wasn't sure if you aimed to see whether I looked at the planets or stared at my body, so the following night, I became bolder. I had my binoculars in my hand and once I looked through them at your window. You were clearly focusing on my chest. I threw the binoculars to the side and posed for you. Tuesday night, I felt your dedication to my studies deserved something from me too. So I posed for you in profile. The binoculars you saw in my hand were used only once: I saw your hand moving down and I assumed you were jacking off. Was I right?"
There was no way I could deny the truth. I blushed and gazed embarrassingly at her pretty face, "Mara, you are beautiful, both mind and body. Why were you playing with me?"
She moved closer still, and her covered tits pressed against my back, "Leon, dear. I liked you more than any teacher in high school. I was even convinced I was in love with you. You, of course, had no idea how I felt. The idea of getting private lessons came to me because I wanted to be near you. Your help in physics is highly appreciated, but at the same time, the more I learned about you as a person, I fell for you."
I turned around and looked at her face, "Mara, I like you. I like you a lot. And your body is perfect: Gorgeous, athletic and very sexy. But I am your teacher and I am older than you by 13 years."
"Officially you are no longer my teacher. And 13 years mean absolutely nothing. Al Pacino, Robert De Niro, Hugh Jackman, and many others are happily married with women who are MUCH younger than them."
"Girl, I am not a movie star..."
"What about the former French president, Nicolas Sarkozy, the former Brazilian president, Michel Temer who is 42 years older than his wife, and of course Donald Trump?"
"I give up."
"Much better. Now stop arguing, and please, kiss me."
"Mara, I wasn't ready for all that. Don't you think we first have to consider the consequences?"
"I do not. But you may. I think I should go home now. I'll skip the coffee and leave the pralines on the table. Today is Thursday. My next lesson is supposed to be next Tuesday. If you rather I won't show up, phone or text me the word NO. Otherwise, I'll be here, but not for physics. My body wishes to feel yours, and I think your body wants the same thing. So the only question is if your mind will accept it or not. Good night, and I really hope to see you next Tuesday." And then she left.
...
If I said I slept only 12 hours between Thursday and the following Tuesday, it would not be a lie. I had sleepless nights, occasionally dozing for an hour or two, dreaming about finding Mara in my bed or peeking at me through the window. Twice I even dreamt about having sex with her. Both times I orgasmed but woke up with cold sweat.
I was perplexed. I knew I wanted her. I had the urge to kiss her luscious lips, to have her in my arms, to conquer her amazing body. However, my super-ego rejected everything, telling me she was too young and naive and didn't know what she was doing. My conscience whispered, "She is not for you. Mara belongs with a young college student. You should find an older, more mature lady." I was torn.
On Tuesday, I tutored one of my other students and was distracted. He just giggled and commented, "Dr. Esposito, you have something else on your mind. I better go home and come back next time."
I mumbled, "You don't have to do it," but I was happy he left before I embarrassed myself.
I didn't contact Mara later. By 5 pm I shaved, showered, wore clean clothes and waited for Mara to show up, not knowing how to behave.
She knocked softly on my front door at 6:05 pm. I opened it and saw her wearing a short black dress with matching 3" heel shoes. Unlike before, her long hair was not arranged in a ponytail and framed her pretty face perfectly. Red lipstick decorated her full lips.
