You bang your sister-in-law in the hot tub, you don't care who watches

With big wet titties shining in your face and a hand gripping your hard cock, it's impossible to say no. You nod to your little brother's soon-to-be ex-wife. "Let's fuck."

She climbs into your hand and starts grinding herself on your boner; only her thin panties and your wet trunks separate you.

Your sister stands up and announces, "I AM NOT WITNESSING THIS!"

Her husband grabs her hand and pulls her back down into the water. "Come on, dear. Feel under the water. I need you NOW."

With her conservative upbringing, her husband's requests are commands from God: she must obey. She rubs him under the water. He yanks her into his lap. She yelps in surprise, but then hums in approval. She loves it when he takes control. She mounts him and covers him with kisses.

You don't kiss your sister-in-law. You stare at those big, slick tits that squish into your chest. You reach behind her back and grip the clasp. Unleash her massive mammaries from her constricting bra. She flicks the soaked bra up onto the deck and pushes her soft, bare tits back into you.

"No," you say. You grab her shoulders and push her back. YOU NEED TO SEE.

Glistening tits reflecting the moonlight. So fucking big. You lift one and let it fall. It wetly slaps against her ribcage. You lick up the water droplets on her wet globes. You slurp on her hard nipples.

She moans. She raises herself and maneuvers under the water. She pulls your hard cock out of your trunks and rips her wet panties to the side. She moans as she sits down onto your hard cock. She's so tight. The panties rub on your shaft. Your tip buries deep in wetness. You don't care. You push her fat tits together and try to suck both her nipples at once.

Your sister, on the other side of the hot tub, moans. "What's gotten into you tonight? You're an animal."

You know exactly what's gotten into him. He stares at you sucking your sister-in-law's massive milkers while he fucks his wife. He wishes your mouth were his. He pounds up into his wife. She's no longer riding. She's getting jackhammered from below. She grips her husband's shoulders and moans. She takes the rough pounding. "Yes! FILL ME!" your sister screams into the night.

You bury your face in your brother's wife's sternum. You squish the big tits on either side of your face. You slide your cheeks up and down on her slick skin. Without warning, your sister-in-law's tight pussy milks cum from your cock. You ooze into her. You squeeze her tits and moan, "Oh my god, this is heaven."

Your sister-in-law asks, "Did you just come in me?"

You pant, trying to catch your breath. "Yeah. Is that a problem?"

"It may be in 40 weeks if I get pregnant." She climbs off her lap, holds her nipples behind her forearms. "Now I have to stay with your brother until I get my period. I can't divorce him if I'm pregnant."
