I had my introduction to sex when I was in grade 12.

We had a new "biology" teacher join the faculty. Not did she have impressive statistics, but she was also from an all girls college with a reputation. Anyway, on the annual day celebrations, where I was taking part in a play, she invited me to accompany her to "see" the new wing that had just been developed. While walking she took me right up to the last classroom down the hall.

The recently waxed floors were very slippery and she constantlykept "slipping" and grabbing my elbow. We were in a giggly mood and I felt her breasts brush me a couple of times. In the last class she suggested that we go in. Near the middle of the blackboard, however she "slipped" and as she "grabbed" me, I fell on top of her. My chest pressing down on her breasts and I could feel the heat between her legs. I lay there, frozen, not knowing what to do next, when she flipped me over and was astride me.

She said "Ever since I've seen you I wanted to have you inside me. Now show mama, what you've got", and she opened up her blouse and bra and let her huge tits out.

I didn't need any encouragement, as I grabbed them and started sucking on them, as she started opening the fly on my pants. My length "jumped" out as soon as it was free and immediately felt her hot teasing softness. She eased my throbbing length right up into her wet love warmth and started moving up and down on me. Within just a few strokes I felt ready to burst and shot my load deep into her cunt. I could see that she had not "enjoyed" herself. She got off me and said "My my, your little pecker has gotten dirty, let me clean it for you", and kneeling in front of me took my length into her mouth and started giving me a delicious play job. I was again ready to "blow" when I took it out and motioned her to turn around. She readily complied and turned her wet teasing private part towards me, on her fours. I entered her from behind, like an amateur and thrust right into her. That made her gasp and turned me on even more. And I started pounding away, and she started moaning softly first then more loudly and finally screaming "Give it to me! Common, give it to me! I kept banging away, instinctively, till I heard her moan, that turned into almost a scream.

I felt her softness close on my length and literally shudder as she experienced a massive orgasm, and just then I felt my length explode as well and fill up her already spunk filled warmth with more cum. As we both collapsed on to the bare shiny polished floor.
