I invited a tipsy older female coworker home. Chisato-san (48 years old), married for 24 years. We talked and listened to her troubles, and she seemed to be in high spirits today. "I'm so tired, can you give me a shoulder rub?" "Yes! As you wish, senior!" As we continued chatting while giving her a shoulder rub... When she started complaining about her husband, she said, "I'm so tired, I can't even move anymore, and we haven't had sex in ages." "Really? What about you? How do you deal with it?" I asked casually, and she replied, "I do it myself. Want to see?" "Whoa, whoa, senior, that's..." Before I could stop her, Chisato-san started on her own. As she let out a sweet sigh, she reached for my crotch and said, "Show me yours too." "I can't do that with my senior!" I protested, but my cock was already hard. "Sorry, husband! I'll take care of her!" We had raw, creampie sex until morning.
