I'm 57 years old, and the only person I've ever committed adultery with is my son. He was born when I was thirty-six, and I first let him fuck me when he was fourteen. His father was working away, and my pussy was thirsty for a cock. Now, whenever my husband is not around, my son fucks me. Sometimes it starts as rape, with me resisting, but, as soon as his cock begins ramming inside me and rubbing against my swollen clit, I can no longer resist. When he finishes with his fucking, my poor cunt is filled with his thick, warm spunk, and I'm exhausted. Not once has his father ever given me such a good fuck.
