My two cents.I have been involved in the swing lifestyle off and on and I noticed a few things. Sasha and Masha obviously had no ground rules going into this so the possibility of emotions creeping in was inevitable. For starters, there WAS a great deal of affection displayed with the constant kissing and caressing. It appeared to me that not only Masha was developing feelings, but TK as well. Masha is obviously high maintenance in bed and TK fucked the shit out of her porn star style. He was rough with her and she fell into her role without hesitation. Hell, she could be a porn star herself after that performance. They have great chemistry in bed and I predict this will not be the last time they get together, with or without Sasha's knowledge. Personally, I believe Sasha made a mistake inviting this into his life.
