It's Tyrion's lucky day. She's interested.

Catelyn Stark responded by nervously biting her lip and turning away, her nipples visibly hardening. "I... my husband..." she muttered weakly, sitting down conveniently on the bed. "If he suspected..."

"Why would he?" said Tyrion, clambering up on the bed beside her. "Most men tend to judge me as small and beneath contempt, and assume that every inch of me is built to the same model. Of course, as you can plainly see, this isn't true, but they don't realize that." He placed a hand on her leg, and began to massage it gently. She responded by a slight moan. "There is no reason for him to even imagine that you and I are involved..."

She turned to look at him for a moment, and took a deep breath. "Oh, Gods, it has been so long..." To Tyrion's surprise, her hand sought out his cock, and began to eagerly jerk at it. With a low groan, she lowered her head, and began to suck on the head of his over-sized member.
