You and your husband have been hoping to get pregnant. You've been trying for more than a year with no success. You're still trying, but during the last few months every time you try to fuck him, his cock just goes flaccid. So the two of you set up an appointment with your friend Anna, a fertility doctor. After you arrived at the appointment, your husband went into the examination room with Anna and you stayed in the waiting room. Now you've been sitting in the waiting room for a while, but there's a nervous, maddening feeling in the pit of your stomach. After pacing for a few minutes, you decide it will be fine to just take a quick peek inside the room to make sure everything is okay.
You open the door and are shocked to see what's going on. Your friend Anna has discarded her doctor's coat, is naked from the waist down, and has pulled her shirt and bra up revealing her firm and perfectly-sized breasts. She has your husband pinned down on the examination table and is riding his cock hard, bouncing up and down rapidly. Every time she slides upward, you can see that his cock is fully erect, bulging as it goes in and out of Anna's pussy. Your husband has an impressive cock, but it's been months since you've seen it at its full length.
"Fuck yeah, that tight pussy feels so good," you hear your husband say, just before he notices your presence in the room. "Fuck yeah, Anna. Oh, hi there, honey. Anna and I were talking about our situation, and she wanted to see what... um... stimulation... um yeah, stimulation, might get me hard. So she pulled her top up and that did the trick all by itself! I mean, look at those perfect tits, right? Anyway, we decided it would be best, under the circumstances, for her to keep the... um... stimulation going, yeah. So she's just warming me up. Why don't you go sit over there in the corner and rub your loose old... oops... I mean your cunt while Anna keeps... um... examining me."
You go over to the corner, sit down, lower your panties, lift up your skirt and start stroking at your already glistening pussy, which your husband notices immediately.
