Finally able the comment as this damn site wont let me write anything. Now here's my opinion. There is nothing really complicated about any of this if you look at it in a different perspective. Though i am no swinger nor would i ever partake in it cause i will never share my girl with anyone. Masha and Sasha embrace this lifestyle with total trust as they enjoy having sex with other couples. With the guest couple, they have fucked them previously, the last time few months ago on the site. So it normal that the more you fuck someone the more uninhibited you get. And one last thing Masha is a NYMPOMANIAC. That girl can suck the chrome of a trailer hitch. Not just a sexaholic but a wild passionate sexaholic. If fucking was an Olympic sport, you might as well give her the gold. As good as Masha is in bed she needs more sex but this does not mean she will leave Sasha for sex as they can fuck other couples who are even better in bed. This have nothing to do with love but just having a good sexual experience. Love is what she has for Sasha and not for the guest. What she has in the guest is a guy she can fulfill her sexual appetite with. Their fucking was ferocious. It lasted 2 hours unfortunately Sasha and the female guest don't have that kind of sex drive. but at the end of the day Sasha is her man. Most men and women married or not can go on holiday meet some stud or hot sexy girl and have wild passionate sex. Don't mean you in love or going to spend the rest of your live the person now does it ?
