I realized my older sister was feeling sexually frustrated. Actually, I was also excited by her pantyhose-covered ass, so our goals aligned! We decided to have sex right then and there. I used some lotion to coat her pantyhose, making them slippery, and the sensation doubled the pleasure! My older sister's sensitivity kept heating up more and more. When I touched her pussy, it was dripping and messy with her own love juices, different from the lotion. I thoroughly enjoyed her lotion-slicked pantyhose ass, and my older sister became completely aroused. She craved my dick, so I had her lick and suck it with her mouth, and when I finally put it in her pussy, she screamed and came hard. I felt so good that I thrust wildly and shot my load inside her.
