I'm a virgin who's depressed because I failed my first time with her. Seeing me like this, my kind-hearted big-breasted sister offers, "How about you practice with my body?" and tries to encourage me using her own body. But she says, "As someone who loves SEX..." and we do dry humping. However, as we rub against each other, my sister's pussy gradually gets wet. I can't hold back any longer because it feels so good, and I start moving my hips... In the end, after actual penetration and coming inside her, instead of getting angry, my sister goes for three consecutive non-stop insertions and orgasms!
