"Marilou, my friend is going to come to stay for a few days for my birthday", my wife said. "Fine" I said. It wasn't fine. Whenever one of my wife's friends came to stay, a few days turned into a week, and the only action my dick was going to see was from the palm of my own hand. I was 40, my wife 45. Marilou was 44 at this time. Marilou, like my wife, was from the Philippines. Marilou was pretty and, for a 44 year old, in really good shape. A nice curvy body and sexy enough for me to get turned on thinking about how she looked naked. I went upstairs to watch some "Netflix" but after an hour this turned into me watching some porn. I was watching a video of a girl sucking on a guy's nipples and giving him a hand job. I love getting my nipples sucked and, to me, it is better than a blow job. Anyway, this video got me really turned on, and I wondered if it was worth masturbating or should I just hope that my wife will be in the mood. I could hear her and Marilou downstairs chatting and drinking. It was unlikely so I carried on watching porn. I was just about to get my cock out to have a good wank when the bedroom door opened. It was my wife and Marilou. They had come upstairs so that my wife could open her birthday presents. She opened Marilou's and was happy with the gift. She opened mine, which was a replacement ring after she had lost hers. "Oh, thank-you" she said and she leant over to kiss me. Her hand reached out and touched my nipple. My nipples are really sensitive, especially when I have a semi-hard dick, and I jumped back because I don't like them being touched until I am fully aroused. "Oh, Marilou, he has really sensitive nipples" my wife laughed. I felt really awkward, Marilou laughed and made a joke. "Thank-you for my present" my wife said again, and as she kissed me, she brushed my hardening cock under the blanket. "Oh, what is this. Is it awake?" she said laughing. I glanced at Marilou who looked as awkward as I felt. My wife, clearly drunk, was in a very naughty mood. She pulled the blanket back to reveal a, now, fully erect cock. My cock is average length which, to Filipinas, equates to "big". Marilou's jaw dropped when she saw my cock. "I told you it was big didn't I?" my wife said to Marilou. I was enjoying the flattery, but wasn't sure what to make of the situation. My wife was wearing a silk nightie, and Marilou was wearing a dressing gown. My wife took Marilou's hand, and moved it towards my nipples. Marilou stroked my nipple, then looked at Shella, smiled and moved her hand to my cock. "Wow" she said as she stroked it. Shella then moved closer and started to lick my nipple. This felt great. Marilou took off her dressing gown to show she was wearing just shorts and a t-shirt. She then went down and took my cock in her mouth. At the same time, Shella was licking my one nipple while stroking the other one. Marilou stopped sucking my cock which was a relief, and she moved up and started to suck the nipple that Shella was stroking. Shella then moved behind Marilou and took off her top, revealing a beautiful pair of tits. Shella started to suck on one of Marilou's tits. I moved my hand to Marilou's ass, and started to massage her butt cheeks and now it was my turn to start sucking her other nipple. Marilou moaned as this husband and wife team feasted on her beautiful tits. I moved my hand around and started to rub her pussy with my finger. Shella realised what I was doing and moved down Marilou's body and started to lick her pussy. I could feel Shella's tongue on my fingers, and Marilou was now breathing fast. I pushed a finger into Marilou, and started to suck the other nipple. Soon, my finger was joined by Shella's and Shella guided my other hand to Marilou's asshole and I started to probe that with my thumb. Marilou was now in a complete daze and she wanted my cock in her. She moved her one leg over and, I felt Shella's hand on my cock as she guided me into her best friend. Marilou moaned as she lowered herself onto my 6 inch cock. Her face was a picture as she arched backwards to take in the full length. Shella positioned herself so her ass was facing me and she and Marilou were now in a tongue fight. I took a wet finger, and started to play with Shella's ass. She usually stops me from doing this, but I never stop trying. This time, she was happy to let me stick the finger in her ass. Marilou, at this time, had stopped kissing Shella and was moving fast on my cock. I felt her pussy tighten around my cock as she came. She got off my cock, and Shella took over in a reverse cow girl position. Marilou looked exhausted, but I motioned for her to come to me, and we kissed deeply as my wife fucked me. Marilou went down and started to suck my nipple. I felt Shella's pussy tighten as she came. She then went off my cock and started to suck my balls and gave me a hand job. I didn't really want to cum into the air, so I pulled Marilou over my body. Shella again guided her husband's cock into her best friend's pussy and moved around and started to suck my nipple. "Girls, I am going to cum" I said, not sure if Marilou wanted my seed in her, and not sure if Shella wanted my seed in her best friend. Shella stopped sucking my nipple, and said something in Tagalog. Marilou nodded, and it was obvious I was going to cum in Marilou tonight. Marilou fastened her pace, and I could, again, feel her pussy tightening around my throbbing cock as we both came. Marilou and Shella laughed as my cum started to drip from Marilou's pussy. Marilou climbed off me, lay back, and I stroked her beautiful tits. When I heard her moaning, again, I looked and realised that Shella was licking my cum out of her pussy. Marilou stayed another 4 days after that, three of which she slept with me while Shella slept in the spare room. On the last night, we had another threesome. But, the magic and experience of the first night will always live long in my memory.
