My Wife's Sister

I married a gorgeous Japanese girl, Aimi, three years ago. We met at work where she is also an engineer. We worked closely on a project for three months and she was very warm and friendly, so I asked her out. We got married about a year later and she invited her sister, Mari, over to the U.S. to be her bridesmaid. When I met her the first time at the airport I thought, “Oh my god! I’ve picked the wrong sister to marry!” Mari was stunning and so gorgeous that I almost fainted when I saw her! She smiled and gave me a big hug. Her body was so tiny; just the type of body that I love to have under me and fuck slowly. “It’s so nice to meet you at last, Charles. Aimi has told me so much about you and how you two met.” She was rubbing my back and being awfully affectionate, but Aimi didn’t seem to mind. “You’re English is so good and I love your accent, too. Aimi has lost her cute accent pretty much.” “Thank you. I work with a lot of Americans in Tokyo, so that’s where I’m able to practice my English.” When we got home, Mari settled into the guest room, then we went out to dinner. We had a pleasant Japanese dinner, talked, and got to know each other. The following day, Mari slept in and Aimi and I went to work. When we got home, Aimi immediately left to do grocery shopping. I went looking for Mari and found her in the guest room laying on the bed and wearing only a slip. Damn! She looked so good and seductive! “Hi. I just wanted to see if you needed anything.” “Actually, Charles, I ...

... could use a back rub. That long plane flight did a number on my back.” If Mari was trying to seduce me, then she was doing all the right things. My wife was not home; she was on the bed wearing only a slip and looking oh so seductive; and she just asked me for a back rub. I felt sure that giving her one could start something, but I did it anyway. “Oh, well maybe I can help with that.” I crawled on the bed as she lay there face down. I straddled her legs and started giving her a back rub as best I could. I worked from her shoulders down to her lower back, then back to her shoulders. “Mmm. That feels wonderful, Charles. You’re hired.” I was sitting there on Mari, her gorgeous body under me; her long black hair flowing out on the bed to one side. I reached up and ran my hand over her head and down to her neck, and then up to her head again. “You have beautiful hair, Mari.” “Thank you. You can massage my scalp too if you want. That would feel great.” As I leaned forward so I could use both hands to massage her scalp, my cock press hard against her ass. I felt like I was about to fuck her and started to thrust against her ass involuntarily. Mari whispered, “Charles, are you getting aroused like I am?” That shocked the hell out of me and I realized what I’d been doing. “Oh god! I’m sorry. I’m being really inappropriate,” and I leaned back and stopped what I was doing, even though my thoughts we still on having sex with her. “Oh, don’t apologize, Charles. I think it’s nice.” As I ...
