My slightly chubby sister is always kind to me. She doesn't have a boyfriend, so she always uses my body to practice sex. I don't mind it either, so I relieve the stress from my part-time job by burying my face in her cleavage and letting her touch my dick. Today, my sister squeezed my dick between her big, shining G-cup breasts, squeezed out my pre-cum with a footjob, and gave me persistent French kisses, so I came a lot again today.
