Ok so I was at the cinema with my girlfriend and we were making out and I started fingering her, but the film ended before we could finish so we went to the park at the other end of town and found a secluded tree grove. We sat down and carried on from where we had left off. So after five minutes she squirted, hell yeh, and then we just sat there. After 10 minutes she asked me finger her again, so I did and then she said it was my turn. So she lay me down, pulled down my trousers and started wanking me off, half way there she put her finger in my arse, she was pumping my cock and arse it was amazing!!! I cummed all over her and she licked it off.
That was my intro to anal masturbation, now I always put a seven inch marker pen in my arse when masturbating. I often just sit there with a pen in my arse whilst doing work, it's so amazing, in fact I have got a pen up my arse now.
