Sam figured that her husband would catch on to how she was going to show why she was with him. He was, after all, smart like that. And sure enough, once they were in the bedroom kissing, she could feel him starting to become aroused.
Soon, he had her shirt was off, and Sam groaned as she wrapped her arms around him, her head lolling back. "Oh God," she gasped, feeling herself starting to become wet as her own arousal started to grow, fueled by his.
When his hand pressed between her legs, she groaned, pushing her hips forward. she wanted to feel more, though, because the material of her pants were getting in the way, and when he showed her exactly what he wanted to do to her, she shuddered, her hand running down to cup his cock through his pants.
If that's what you want...
Reaching over, she stripped his clothes off before undoing her pants and pushing them down with her panties and kicking it aside. She then took his hand and pulled him to the bed.
