Not Crossdressed Didn't Care

I've been having an affair with an 18 year old crossdresser. She has a smallish cock or clit, and has small little a cup tits with cute puffy nipples that stick out like cones. Whenever she isn't wearing a bra you can see the shape of her areola and nipples through the material. I am married, my wife quite frankly looks almost like an older sister to the gurl. She is 40, both are 5ft. 8in tall, both weigh 125lbs., My wife and the gurl both have pretty straight bodies, not much of a waist, both have a cup tits, though the girls are actually a bit bigger than my wifes. Their hair is the same dark brown and just past the shoulders for the wife, and just above for the gurl. My wife and I often roleplay with her dressed in Tee shirt, jeans, white mens underwear, and I buttfuck her with her on her belly like we're both guys.

I've never had sex with a guy until this gurl. It started 2 years ago, my wife doesn't know. I think I might have been his first to fuck him, though he admits he did suck two guys before me. The thing is that whenever he comes over he is totally SHE, dressed, made up, sexy as hell. This afternoon, I went over to his parents house, they are out for the week. He wasn't dressed yet, not made up or anything. I fucked him anyway. I knew it was fucking a guy, totally a guy, and I didn't care, I wanted his ass and I took it and he liked it. Thinking back, I really like fucking the gurl over the boy, but this afternoon I didn't care, I needed someone to fuck and he was available. He just sent me a shot of his hole, with my cum leaking out of it. I'm hard again, he said to come over, but I wanted to wait to fuck my wife instead, get some pussy and get back to feeling normal again. She didn't want to fuck, so I said I was going next door to borrow a tool. She asked if I wasn't going next door to fuck him again. She asked if he's dressed. Questioning look on my face . . . "You didn't turn off the motion activated cameras a couple of weeks ago. I saw it all ! By the way, you're very HOT!" I texted and told him to get dressed. I went over again and fucked HER. All my wife asked was if I was sated for a little while, until we can eat, shower and I can show her just what I did to him-her.
