Your sister calls you up and asks about your life some and then says she has an embarrassing question for you. She and her husband are trying to get pregnant, and they’re wondering what the genes on your and her side of the family are like for penises. You’re surprised but aroused by the question. What does your penis look like, she wants to know. What are your balls like? Does it curve? Are your balls tight or loose? She’s just trying to envision what her baby might look like if it’s a boy! There’s a good way to solve this: Video chat! You call each other on Video chat and start video chatting. She asks to see your penis and you take it out and show her. Now she wants to know how you masturbate, so you start stroking yourself for her. She says it’s only fair for her to show you what her breasts look like, so you can know about the breast genes in the family. It feels like “you show me yours I’ll show you mine” but with your sister. She takes off her shirt and you see that hers are large and plump. It just keeps going; somehow you’re watching your adult sister strip for you and play with her boobs, and she’s every bit as hot as you thought she might be, and you blow your load watching her. It’s all ok since it was just for learning about the family genes if you two have kids, right? But now that you know how hot she is, it’s going to be hard to keep it in your pants when you see her at family gatherings!
