My sister shows me how to have sex and lets me touch her privates

I've always been curious about sex and how it works, but I never had the opportunity to learn until my sister decided to give me a lesson. She's a stunning brunette with an incredible body and a sexy, tight ass. One day, she decided to show me how it's done, bending over and giving me a close-up view of her private parts. I was hooked! We got down to business, and she taught me how to please her, taking my cock deep into her throat. She rode me like a pro, showing off her skills as a cowgirl. It was an amazing experience, and I couldn't hold back, cumming inside her mouth. We're just a couple of amateurs having fun, but I'm grateful to her for teaching me the ropes of sex.
