Continuing to suck her breasts I let my hand turn over so my fingers were now touching her. I felt the wet material and the outline of her swollen lips. I pushed slightly, making circles around the area, memorizing the feel of this moment, making out the bulge of her clit through the thin layer of clothing.
"Oh God." Nina moaned, her hips bucking a little. "That feels so good."
I raised my head from her breasts and moved it back up, so I was staring in her eyes. They were shining and very excited.
"It's not supposed to feel bad." I whispered to her, bringing my lips to hers once more.
Her tongue plunged into my mouth, attacking mine viciously, her lips sucking it into her mouth. Her hand slid down to my crotch and began to squeeze my erection through my dress pants, making my own hips begin an involuntary rhythm.
My fingers left her junction and continued upward, across her lower stomach, seeking and finding the top of her pantyhose just under her belly button. I slid one finger beneath the elastic, touching her bare stomach, letting it slide back and forth along the edge.
"Yes." She whispered into my mouth, sucking my upper lip, running her tongue along my teeth.
I pushed downward once again, this time beneath the pantyhose, my fingers feeling the soft flesh of her lower stomach and finally encountering coarse, curly hair. I pushed onward and she spread her legs even more. I touched warm wetness and smooth lips, felt the erect clit and then my middle finger was resting against her lips. Her crotch began to push upward against my hand, demanding more, so I gave it to her. My middle finger slowly slid into her tight warmth, her membranes clutching at me greedily. It slid in easily, lubricated by her copious juices. She was tight, tighter than anything I'd ever felt before, tight enough that I worried if intercourse was even possible with her.
"Oh Bill." She moaned, squeezing me extra hard. Suddenly her fingers were fumbling with my belt. She pulled the end free of the loop and gave a sharp yank, freeing the buckle.
"Nina?" I asked, panting.
"I want to feel it." She told me, nipping at my neck.
I nodded and her fingers popped open the button on my pants. She yanked the zipper down and plunged her hand inside, diving beneath my underwear. Suddenly her cool, eager fingers were around my cock, feeling it, touching it, moving harshly over it while her hips continued to move up and down under my own fingers.
She was inexpert at the job but that didn't matter. The feel of her hand on my bare flesh was thrilling enough, the thought that she was touching me intimately driving me on. I let my finger slide out of her a little and I began pushing against her clit, rubbing my hand in circles.
"Ohhhh!" She moaned, her own hand becoming erratic and finally dropping away from me. "Yesss Bill!" She cried, grabbing my forearm and pulling it harder into her. Her hips were now blurring up and down, moving with instinctive force. Her juices were soaking me as I rubbed her clit and slid my digit in and out.
She lost the ability to speak coherently. She only moaned and said things like, "Ohhh yess, ohhh Bill, ooooh."
Finally she arched upward and all of her muscles tightened. Her fingernails bit into my forearm painfully and from her lips came: "Mmmmmmm!"
I continued to rub her until she relaxed once more, her butt dropping back down to the blanket. A relaxed sigh escaped from her lips and she looked up at me. Slowly I pulled my hand from her crotch. It was dripping wet and I resisted the urge to put it to my nose, to inhale her special scent for the first time.
"Wow." She muttered, taking deep breaths.
"Are you okay?" I asked gently, a little worried that I'd overwhelmed her.
"Yesss." She breathed. "That was the most incredible thing I've ever felt. Having you do it is much better than…" She stopped suddenly, realizing what she was saying.
I must say that I was shocked by her words. "Better than what?" I asked before I could stop myself.
Though it was very dim lighting I could tell she was blushing again. "Well," She said, giggling a little. "You know? After our other, uh, sessions, I had to do something to get myself to sleep at night. There's nothing wrong with it you know."
No there was nothing wrong with it. In fact the mental image of Nina laying in her bed and masturbating herself was so powerful and erotic that I nearly came just thinking about it. For some reason I just hadn't considered the possibility that she was doing that, although my first act upon returning home was a quick session with my five best friends.
"I think that's very sexy." I told her.
She giggled again. "Now you know one of my secrets. You won't tell anyone, will you?"
"Of course not." I said, laughing. Who would I tell? Her Dad? Her Mom?
"It's just embarrassing." She said, her hand touching my cheek. "But it was nothing like it felt when you did it to me just now. I mean, wow." She shook her head.
"I'm glad I could help." I said, kissing her lips.
"What about you?" She asked. "Do you ever, you know?"
"Masturbate?" I asked teasingly.
"Well, yes." She nodded.
Now had I been a normal teenager I wouldn't have admitted it under torture. I would have claimed that I'd never so much as laid a finger on my penis, not even to pee, not even to wash it. Teenagers have a horror of being discovered masturbating. But I was not an ordinary teenager and I knew that women were as turned on by the thought of a guy jerking off as guys were thinking about women doing it.
"All the time." I told her. "Especially after one of our sessions. Especially then."
"Really?" She asked, her eyes shining with arousal again.
"Really." I nodded. "After we make out I HAVE to. You see, when I'm uh, turned on for a long time without uh, relief, it actually causes pain if I don't."
"You mean blue balls?" She said clinically.
I laughed. "Nina, you never fail to surprise me." I told her. "Yes, that's what I mean."
"So every time you and I have made out you've gone home and…"
"Whacked off." I confirmed.
"Wow." She whispered, licking her lips. "What do you think about when you do it?"
"You." I said. "Making love to you."
She gulped, her eyes drifting down to my dick, which was still protruding through my pants, as erect as it could be. "So you're going to do that tonight when you get home?" She asked.
"First thing." I answered.
She hesitated for a second. "Maybe I could, you know, do it for you?"
"What?" I asked, my dick giving a twitch at the thought.
"You did it for me." She said, sliding her hand over my chest. "The least I could do is return the favor, right?"
I swallowed. "Well." I said. "If you really want to…"
"I do." She whispered, pushing me onto my back. "Just tell me how to do it."
She reached out and grasped me once more, encircling my shaft with her fingers.
"Do I move it up and down?" She asked, doing just that.
"Yeah." I breathed, lost in the sensation of her hand upon me. I directed her to move it upward a little more and to increase her speed and loosen her grip. Eager to learn, she complied. Her hand stroked me softly, finally gaining speed as my hips began to move up and down.
"Involuntary action of voluntary muscles." She said, watching this phenomenon. She speeded up, increasing the pressure.
"How much will come out?" She asked me, just as I started to feel the tingles running up my spine.
"A lot at this point." I groaned, actually humping her hand.
"Yeah?"
"Yeahhhhhh!" I breathed. "I'm gonna…"
She watched intently as orgasm assaulted me and my dick began to spurt jet after jet of pent up semen from the head. I groaned in pleasure, the exquisite feeling of relief, doubled by the fact that it was not my hand that was providing it. It shot straight up and landed on my stomach, my pants, my shirt. It covered Nina's hand, running down the back of it, sticking to her fingers. The blue ball sensation, which had been building in my testicles, was releived in an instant.
