Biology Studies -- Two Makes Three
This story is a work of fiction. While I myself fantasized about something like this happening when I was in High School, it is only a fantasy.
It was my senior year in high school and my grade point average was barely getting by to be able to graduate. I was 18 and in my second semester. My grades were good enough to graduate in all but one class, Biology. There were a couple of other classmates that were in the same predicament as I was and had resorted to studying together in order to bring our grades up. I had teamed up with Carol, one of my classmates, in order to do some togetherness studying at my house.
On the weekend before a large test, Carol had come over to my house so the two of us could study together. The chapters we were having trouble with the most was genetics and reproduction. While going over some of the stuff in the book, we began relating different family traits we though might be genetically related. Since we were studying reproduction, it somehow lead to comparing our own bodies with the descriptions and drawings in our books.
That weekend before the big test, Carol's fascination with the size and shape of my cock, lead to giving me a really nice blowjob. My exploration of Carol's slit lead to stimulating her clit and causing her to have an orgasm. After her orgasm was subsiding, I hugged her tightly. In this position, the alignment of our bodies had my cock lined up with her slick pussy. It didn't take much shifting of our bodies for my cock to soon be imbedded into her. From there, instinct took over and it wasn't long before her womb was filled with my sperm, to overflowing.
Our weekend studies together enabled both of us to maintain a passing grade, but neither of us were out of the woods as far as our biology grades. With that in mind, both of us resolved that we'd be spending a lot of weekends together.
The weekend after the big test, Carol and I were cracking the books again in my bedroom. My parents had gone to the club again; a predictable Saturday night staple for them. It wasn't long before Carol was teasing me about whether my cock was up to full size, like last weekend. Her hand on my crotch, squeezing and rubbing guaranteed that my cock was large and hard.
I did nothing to dissuade her when her hand undid my belt and unzipped my fly. Her hand now had easier access and did not have to fight my pants to get to my cock. Her hand slipped effortlessly into the opening of my boxers, pulling my swelling cock into view. After a week of not feeling her touch, tt felt wonderful to have her soft fingers wrapped around my cock again, stroking me into hardness. When my cock was nice and firm, Carol gave me a lustful grin, bent down and slipped her lips over the head of my shaft. Slowly bobbing up and down, she swirled her tongue on my shaft on the up-stroke. Apparently, she had been doing some research on the subject since last weekend and she was putting that new-found knowledge to good use. When my cock erupted and filled her mouth with cum, she greedily swallowed every drop.
