It might just have been my imagination, but I thought I could even pick out exactly what was turning them on. Iva had once told me that was possible, ...nd I had no doubt that it came naturally to her. But this was probably the first time I'd noticed it myself. Iva was enjoying almost everything about it. The feel of me inside her, my mother's oral ministrations, the excitement of seeing my mother respond so enthusiastically to the fist she was pushing in and out of her, and the simple knowledge. Tomorrow my period would probably start and I didn't want to do what I had planned with a string hanging out of me.As I finished dressing, I thought about Cindy and the fact that I wanted to have the experience of giving oral sex before she did, but decided it was stupid to hold a secret contest, after all, it wasn't like I'd be able to brag about it. When it happens, it'll happen.Eddie and I just made it to the bus. We climbed on as the driver gave us a dirty look for being late. I went back,. My left hand ran along the top on his trousers as my rite hand slowly fingered his zipThe outline of his cock seemed to be getting bigger and was rock hard. My left hand hovered round the one button before I flicked it unfastened. I then slowly unfastened his zip and my eyes focussed immediately on his throbbing cock. Take these down a bit I said pulling at his trousers and these as well holding the side of his boxers. As his pants passed over his prick it didn't move at all,such was its. My blood quickly went to my cock and it got hard rather quickly. I grabbed it and jacked off while I watched the hot chick being fucked, and sucking off a guy. I was getting extremely close to Cumming and was pumping furiously now. I felt my balls tingling, then jerk. Cum came up through my shaft, six jets of it came shooting out, landing on my discarded clothes. As I had my orgasm, I let out a loud groan and felt a little weak in the knees. After my little masturbation session, I went to go.
