Brother-in-law sucks my breast like a calf, all in secret.

The forbidden pleasure between us escalates as our bodies crave more of each other's touch. Under the covers, your brother-in-law takes me in his mouth, his warm tongue swirling around my hardened nipple. The sensation sends shivers down my spine. He sucks hungrily, like a newborn at its mother's breast, yet there's an underlying desire in his movements that speaks of something deeper. His hands roam freely, exploring the curves of my waist and hips, teasingly skirting over my bare thighs. His breathing becomes ragged, mirroring my own as we lose ourselves in this illicit encounter. This secret tryst is electrifying - dangerous yet irresistible. We are bound together by our desires, and nothing else matters.
