With the threat of

The chill breeze cools you off. You recover in a deck chair, trying to pick on splinters in your back.

The sliding door opens. Your busty sister-in-law gets pushed out to the deck. Your sex crazed wife follows holding a kitchen knife to her throat. You realize why this **** was never approved for consumption.

Tears well in your sister-in-law’s eyes, “Don’t hurt me. What do you want me to do?”

Your wife says, “He thinks you have big boobs. Show him. If you have big boobs, he’ll get hard and you can leave. If not, you’ll need to find me someone who does.”

Your sister-in-law looks at you and pleads, “I’m a D-cup. Is that big enough?”

Oh fuck. Plenty big. You nod. Your wife presses the knife to her skin. “Show him.”

Your sister-in-law reaches down and pulls up her sweater. You see her tan soft stomach. Her hands dig under the band of her bra. With one last effort she lifts up her bra and sweater and covers her face, and exposing her bare tits to the November breeze.

Big, full tits hang on her body. Much bigger than expected but a little saggy for someone so young. Her nipples harden in the cold. So does your cock. She has huge dark pink areola, and long suckable nipples.

“Jump,” you say.

She doesn’t ask how high. She bounces and so do her big tits. Your cock grows. Your wife sees it. She drops the knife and rushes past your buxom bouncing sister-in-law. She jumps in your lap and guides your hard cock into her eager pussy.

Your sister-in-law finally breaks down and cries. She wails as she goes inside. This isn’t going to end well. At least you know how powerful this **** is, people will **** to have more sex.

Your wife’s grinding herself on your cock has lost your interest. You keep thinking about those big frightened tits. If you could slip the **** to her, she wouldn’t be afraid anymore; she would be horny as fuck. That’s how you’ll solve this. Dose her and fuck her. All will be forgiven.

You stand up. Your wife clings to you, keeping your cock in her pussy. You say, “I need to get something from our room.”

Your feral wife growls, “I don’t care where we go as long as your hard dick is inside me. I need more cum. Give it to me.”

You’re not getting rid of her. Now you have to dose your sister-in-law with your dick continuously in your wife. When does this shot wear off? You barely gave her any.

You walk to the house with a passenger on your cock.
