After our swim, we went inside for a snack and she very bluntly asked me if I had ever taken an enema. I said no, and she said I should come to her room and help her because she was going to do one and she could use my help. I was curious, so I said ok and followed her upstairs. She got out some 'equipment' and filled a bag and handed it to me and asked me if I would insert the tube into her anus for her. I felt really weird, but she is a good friend, so I did it. She told me what to do and after a minute or so, she started masturbating and she made herself orgasm very intensely. She also asked me if I would do some of the masturbation for her so she could enjoy it more. I did whatever she told me to because I felt kind of weird, but I didn't feel threatened or anything. She reached orgasm at least five times in less that two minutes.
