You’re chilling with your sexy stepsister when she suddenly blurts out that the two of you should skinny-dip in the pool. You tell her it doesn’t feel right, but she instantly smirks and accuses you of having a little dick. She’s adamant you have to prove her wrong and before you can react, she yanks your shorts down. She looks, eyes widening a bit, then licks her lips and now she’s definitely ready to give it a try.
