My sister has always loved me, and even now she treats me like a child. When she comes home, she rubs against me, kisses me, and gets overly affectionate with me! I'm not used to being around women, so that alone makes me get hard! I tried to hide it in a hurry, but my sister saw me, and I thought she'd be put off, but she said, "Hey, should I give you a kiss on your dick too?" and started kissing my dick many times and licking it lovingly! It didn't end there, and I ended up having sex with my sister, who was swept away by my actions!
