I have a slightly plump and kind older sister who doesn't have a boyfriend, so she's always using my body to practice sex. I let her touch my dick, bury my face in her deep cleavage, and relieve all the stress from my part-time job. Today, just like always, she sandwiched my dick between her G-cup breasts, squeezed out my pre-cum with a footjob, kept giving me long, passionate tongue kisses, and made me cum again and again.
