More than I bargained for.

Personally: I'm getting more than I bargained for. My wife is becoming more into Kink than I, but I'm the one who started it so it's hard to back out of when she really enjoys it. She says things like; "Let's just do strapon sex for a month or so, and you'll get better at taking it. Then I can fuck you as hard as I want." She likes to really slam me, while gripping my balls. It is so overstimulating that I think I'm going to faint, or die, or cum.

When I'm getting it, I feel so weak that I don't think I could stand. Each thrust with that big dildo of hers is like a punch in the guts, and the feeling like I'm urinating, and maybe 5% of an orgasm. I get hot flashes.

Her birthday is this week, so she wants to give it to me really long and hard tonight. She wants me fastened to a metal bench we bought from etsy. "I'm gonna hurt you so bad. I'm gonna fuck you for an hour, with a noose around your balls." exciting but scary. She wants me gagged so I can't opt out when she gets going. I'm afraid she will see a humbler online and want one.

She gets some physical stimulation from the harness, because it vibrates VERY HARD. But mostly it's the power she enjoys. When she is done fucking, she will lay down on the bed to be licked.
