Tested by wife and MIL
I've always been attracted to older women but my wife is several years younger than me. I'm 41 and my wife is 35. My wife has always been very close to her stepmother, "Jane", who raised her. She's 59 and always been beautiful and sexy in a classy way. Since my FIL died a couple years ago, she flirts with me when we're around, even in front of my wife. Not overtly sexual just sort of "I like those pants/shirt on you" and "have you been working out?", generally complimenting my looks. I also catch her checking me out. My wife knows I'm attracted to Jane and says she has a bit of a crush on me. My wife gets off on it, she's always been really turned on when women flirt with me, even encourages when we're out. Our sex life is not lacking.
My wife has done something very naughty. My wife has taken pics of my cock while we're fucking, then texted them to Jane "accidentally" as if she's sending them to me saying something like "mmm your cock felt so good last night". The first time Jane did not reply but laughingly told my wife later "I think you sent me something by mistake and I'm JEALOUS!!". The second time she replied almost immediately "you did it again...I'm starting to look forward to your mistakes LOL!".
My wife keeps hinting about a threesome but then laughs it off like she's joking, but I really don't think she is. I'm sure my wife is not attracted to Jane but would like to see us fuck. I've never cheated on my wife, but I would love to fuck Jane if a threesome happened (would also fulfill the mother/daughter fantasy). My wife hasn't said so, but I think they are planning on this. I don't want to seem overly eager to my wife, but I don't think we can hold out much longer, this has to come to a climax soon (pun intended).
