What if your GF/Wife wanted to be a substitute would U let her?

[Imconfused]

If your gf or wife told you that she wanted to do this would you let her? or would this not be something you would enjoy?

By any means of the imagination am I a shemale. Though I was thinking. I walk into the bedroom with sexy lengerie on and you are on the bed completely naked. I come over to your side of the bed and start kissing you. You touch me all over and you slowly bring your hand "downtown" and you feel a cock in your hand ( strap on of course) so you start stroking the cock with your hand while playing with my breast. You then tell me to get on the bed and stand on my knees, you again take the cock in your hand and stroke it..while playing with my breast. You then start kissing me while still playing with my cock and you start kissing down my breast to my belly, you then take the cock in your mouth and start stroking it with your mouth. While you are sucking on it you start playing with your own cock. You then get on your hands and knees and I lick your ass..and put some lube on you and slowly insert my cock ( strap on) into you slowly..then bringing it in and out ( not all the way out) You are aroused by me penetrating you from behind and have an explosive orgasm....
