YSN-478 My voluptuous sister makes me sick with her thick body

My sister, who is a bit chubby and always kind to me. She doesn't seem to have a boyfriend, so she uses my body to practice sex all the time. I don't mind it either, so I bury my face in her cleavage or let her touch my dick to relieve stress from work. Today too, she trapped my dick between her bouncy G-cup breasts, squeezed out my pre-cum with a footjob, and gave me relentless tongue kisses, so once again, I ended up cumming a lot thanks to her.
