Sis is home! And she's SO hot as always. She knows it too, walking around in her panties and bra. "What?! It's lie wearing a bikini, shut up!" She jokes with you and asks about your summer. Your girlfriend doesn't live nearby and won't be visiting. You don't really want her to though... I mean... Your sister is here. She catches on especially when she sees your hard dick. She flirts with you and jokes but soon enough she's on her knees practically worshiping your dick. "Only this one time, don't tell!" Mission accomplished, this summer is going to be the best!
