Mac and Tina have been my closest friends since high school. I don't know how this started but close to a year now we have been satisfying each other sexually one night every week. Our nudity around each other boggles my mind and although I don't consider myself bisexual, I participate with Mac satisfying Tina with the ridiculous amount of sex toys we have accumulated. I never have intercourse with Mac but he and I do perform oral sex on each other. None of us have pubic hair anymore, Mac shaves ours and we shave his. He not only penetrates Tina and I with the sex toys but he to is penetrated anally with vibrators, dildos and other toys. Its not every week but we spank each other using our hands, a strap and a paddle. There are times when Mac has both Tina and I side by side as he tries to have us both orgasm at the same time. Whatever modesty I ever had is long gone and same goes for them. I admit I like jerking off Mac and blowing him but I also like penetrating him anally. Tina and I take turns just about every week when we use a strap on to annoy Mac. I don't think he likes us doing it to him but its fun for Tina and I. They have been going together for 7 years and live together now. I'm like a third wheel but once a week we have the most immoral sex I can imagine. It goes on for hours and I love every minute of it and orgasms are relentless. Its crazy, unnatural, sexual satisfaction that has become addictive.
