My sister had a fight with her husband and suddenly showed up at my place where I live alone. She started drinking and got drunk and as a bit of a joke, she took off my pants. When she was half-naked after a bath, my rock-hard cock popped out...! "What?...Are you kidding me? It's more than twice as long and thick as my husband's...!!" "The glans is sticking out so much...If I put something like that in...(gulp)" "You...you've made me so hard..." "That's fine★ I'll let you do it★"
