Why? Why is this, when Im straight and she's bi,and we just like same room,wife swapping with the ladies enjoying each other??? Well....Its far more c...mplex than you might think.A lot of people are swingers because they have more,uh....shall we say,more of an appetite for more just regular sex.A LOT of them are into BD/SM,whips and chains,leather,torture and humilitaion,or being humiliated.And thats OK.Thats fine,if thats what youre into,thats perfectly OK,as long all paries involved agree.But. Mom said, "Jessi, you really look SO nice!" Thanks, Mom."That afternoon we were told that I could go home. Body-Mom said she'd call home and ask Body-Dad to bring me some going-home clothes. "What kind of clothes would you like to wear?" she asked."Oh, it doesn't matter. Bring me the kind of things I normally wear," I said. Body-Mom looked surprised but just said okay.I finished getting dressed, in a black pleated skirt that ended about two inches above my knees, a pink shirt with short sleeves. "I need to go." I said and got out of the car. I sat in my car, Lindsey drove away. I followed at a distance to make sure she made it home fine. I stopped at the end of her street, she pulled into her garage. Then texted me. : thanks for making sure I got home ok. :Then I drove home. I didn't sleep a wink that night! A week later, Lindsey showed up at my house. "I'm going to Europe for the summer, I'm going to miss your birthday so I got you this." She handed me a wrapped gift. Before I could. Her attention was at her hand but suddenly she stopped turned back and asked is that your dick at my ass.These words from her made me mad and i begin to hump her over the clothes. She yelled at me to stop at once and tried pushing me away with her left hand but I was not going to miss that opportunity and over powered her. Pushed her head down and started pressing her ass. She said this is wrong dont do this and was constantly trying to pull her hand out.I raised her nighty up and took my left.
