Shy lust ⇐ Incest

[Anonymous]

This is probably how we can describe what is happening between me and my sister now.
On her last visit to visit us, my wife convinced (practically persuaded) that she would take our sex calmly, and everything happened. I will definitely post more details, as I want to describe everything in detail.
So about shyness. My fantasies about sex with my sister and wife were a fiasco at the same time)
My wife gave the go-ahead, but refused my offer of a threesome. Only once did she see us in the dressing room, going into the steam room.
And my sister is wildly embarrassed to do something with me in front of her.
At most, I kneaded her breasts once and kissed her on the neck, but it felt like that I did this with a mannequin, because there was no mutual affection from her.
But alone, I felt all her lust and unbearable desire. I really want everything to happen in front of my wife on one of her visits, and ideally, for her to film our process on video, but... It’s unlikely.
