As I felt her tense and then relax again I pushed in. The tip was almost in, as I eased a bit more. I stopped to let her adjust my size.Moments later ... pushed in further; but her asshole was pretty tight.I slowly slid in more and more until I was in all the way inside.After a couple of minutes I started moving in and out slowly. We both moaned and almost immediately I exploded.We both collapsed on the bed. I held myself up and slowly eased my dick out from her now stretched asshole. I could not. "Just keep going, Matt. Please. Please. Don't stop. Keep going, this is too good. Oh, I'm gonna cum! Matt, I'm gonna cum!"And he added a second finger. Matt was not Julie, obviously, but all his bisexual friends taught him a thing or two about how to treat a hot pussy. And he was using what he had learnt on his sister, that Saturday night, in his bed.And, just like he expected, as soon as he put the second finger, Sally's hips started to move really fast."Oh, Matt! Yes! Oh... Fuck... That's.... This particular Friday I was still studying when the librarian came over and said she had to shut up, I looked at my watched and saw it was 8pm. As I got my stuff together she led me outside.As she locked up I said “Do you fancy a drink?” as there was a pub just across the road, she said “Why not” I put my books in the car and led her over. I ordered and we sat down as we started talking I studied her, she was around 55, later she told me she was 64 but she didn’t look it, slim, probably too. " I was shocked. "Do you mean, cunnilingus?" She blushed and said, "Uh hum, and she has taught me how to use various types of toys—dildos and vibrators."She then asked me if I'd like to learn how to drive a woman crazy. "Sure," I said, but inside I was kinda hurt because I fancied myself a real pussy eater. "Here's how Anita first taught me. Bend your index finger and place your thumb next to it and look at it. Can you imagine the thumb and finger as labia folds and the knuckle as the clit?".
