Female biker friend
A female friend of mine rides dirtbikes. I wouldnt have much interest in motorbikes but i was over at her house a few weeks ago and she had the bike out doing some maintenance on it. She was just finishing up when I arrived. We chatted in her garage as she put away her tools and other bits then she said, i just want to take the bikd for a quick ride to make sure its all good. She has a big field out the back of her place so i said, grand ill hang on here. She tore off and arrived back about 10mins later. I asked hows the bike. She said fine but that she noticed one of the fence posts down the end of the field was broken, would i mind having a look at it and seeing if i thought it could be fixed. I said no problem assuming id walk down but she said, hop on the back there and ride down with me! I thought she was joking at first but then realised she wasnt. Anyway i hopped on behind her. There is obviously no passenger pegs on the dirtbike or handles so my legs were hanging down and i was holding onto her. It was a bumpy ride down the field and with all the bumping and moving i suddenly got a raging boner behind her on the bike. I had to try hide it from her when i got off the bike. Thankfully she didnt notice or it would have been very embarrassing!
I loved riding the log flume at water parks with my hot older sister. I'd always sit behind her, press myself against her ass and body, and go up her wet shirt as we headed downhill or hit the bottom. Really handled her like crazy, and went down her shorts a few times. She didn't mind and knew it would happen, and would smile and tell me "At least it was you all over me and not some strange guy". The few times I was in front of her, she'd wrap her arms and hands around me, and dig her killer-long, red nails into me until leaving lines on my skin or drawing a hint of blood. Same as with her, I knew it was coming, and looked way forward to it. We'd be heading home, and she'd ask "Did I get you good this time? I know you had your fun with me".
Was this in the UK? I have an odd feeling I might know the person you mean!
Went jet skiing with the girl next door. She moved my hands from her waist to her chest after a bit. Got hard and couldn't hide it. She stopped after a while and asked if I was having fun. She wiggled her ass and said it felt like I was enjoying it. Didn't get much after that but still fun when I see her
