Caught in the Act

I was lying on my side facing away from my husband when he came home late one night. His hand sneaked under my shirt and into my pants before I even had a chance to turn around, his fingers finding me wet and ready. He pushed two inside immediately, curling them up against my g-spot as he rubbed his thumb over my clit. I moaned into the pillow, knowing we shouldn't but unable to stop myself from riding his hand harder.
