Clair wants Joe's cum in her sister

"Ohhhh fuckkkk" Clair moaned in excitement as her husband's cock slid into her sister's cunt. Watching his meat spreading open those pussy lips and ploughing into her **** sister's body sent a thrill of lust and adrenaline through Clair like nothing she had experienced before.

Joe lifted Helen's knees slightly, letting him push deep into her. Her pussy was hot and tight, but the lubrication from Clair's hole helped him slide into her sister's. Glancing up from the sight of his length slipping into his sister-in-law's depths, he saw Clair slip one hand between her own thighs to rub her clit. Perched over Helen's slack face, Clair strummed herself whilst watching Joe steadily pump himself towards release.

"Oh honey, does she feel good? are you going to shoot your cum in my sister's pussy?"

"Yes baby, she feels wonderful. She's hot and tight and I'm going to cum soon. Do you want to see me fill Helen with my seed?"

"Yeah... fill the bitch up. Fill her with your cum. She's not on any birth control, you know. Breed her for me. Give me a niece or nephew. Plant your baby in my sister."

This pushed Joe quickly over the edge and his cock shuddered, rope after rope of sperm splashing Helen's cervix. He groaned in satisfaction as he felt himself softening in the warm embrace of her slit, before his cock slipped free. Husband and wife stared in fascination as Helen's wetly glistening lips revealed a single milky pearl of spunk before they closed up.
