I used to be present more often than I am now. In these covid times, she's only got one bull she can see, and only once in a while. Plus, we have a family member living in our basement as a roommate for now, so we can't host. So when I can't be there in person, I'm just at home while the ******* sleep, or perhaps out with them in the afternoon, while their mom is out "shopping" or "catching up with a girlfriend" (getting thoroughly fucked by another man). Usually I'm waiting for pictures and/or video clips from her (or more frequently, from her bull), and trying to find a moment to sneak away and ******* myself checking them out.
When I do get to be there, she likes to sit on my face while she kneels in front of him and takes him in her mouth right above me, which is indeed a jealousy-inducing view. Then she'll either tell me where to sit and watch, or have me kneel by the bed so she can hold my hand and look into my eyes while he fucks her from behind. A few times I've been told to hold her ankles apart, up about as high as her head, so he can push himself in deeper. A few times she's had me fluff her bull, if it's a guy who isn't turned off by that. One bull used to have me lay under her in 69 position and lick her clit while she gripped my caged dick, his big cock stretching her open, right up close and in my face. Once, after he'd made her cum several times, he pulled out of her, told me to open my mouth, and shot his load there. He told me not to swallow it and had me kiss her and "share it all with her." That was kind of intense. I've never been allowed to jerk off while she's getting laid before, but she's said maybe it'll happen sometime.
Back when we didn't work remotely and the house was empty during the day, I'd occasionally get pictures of her and a bull laying on my pillow, spent and sweaty after a spontaneous lunch break rendezvous, while I was at work.
