An acquaintance came to visit me after I was hospitalized. There was a cute woman next to me, so I thought she was her girlfriend or someone at work, but then I was surprised to find that she was a sister I had been playing with with her in the past! After meeting again for the first time in over 10 years, my rapidly grown, sexy body stimulated my abstinence-free cock. Taking advantage of the fact that my friend left her seat, I immediately asked my younger sister to take care of her, and although she was confused, she said to her beg and said "it's a secret" and had raw sex!!
