[Sabaneko] Oppai Suiren (ONEgai SYOTAiken) [MrBubbles]

Swim lessons turn into something far more intimate when a busty young coach guides eager little Hiro-kun through his flutter kicks at the pool. Between laps she lets him nurse at her huge breasts and enjoy paizuri, and with no condom on hand she offers him her tight ass instead so he can finish deep inside. Their post-practice shower becomes the real main event, with the pair promising to 'train' together every day before getting in the water.
