Wet and ready, Linda clambered onto the bed alongside him. Both naked. His delicious, hard cock jutted temptingly. 

Linda, hot in anticipation of his delicate fingers, bringing her exquisite pleasure by stroking, nipping, probing her every orifice. Mouth and tongue would follow only to linger around her clit. 

Passion rising, Linda held his gorgeous cock, and wordlessly, he directed it to her wetness. Smooth, explosive entry before that divine log-like penetration, and both humped repeatedly until an ecstatic shared orgasm hit them.  

Gasping, he murmured, “Open marriage forever.” 

“You’re my darling brother-in-law,” Linda whispered, giggling. “While he’s away fucking your Rachel.”
