I'm living with her while we consider getting married, but her younger sister came to stay. This sister was trouble; she had enormous breasts that made up for her flat-chested older sister's lack, with a childlike face—she was literally a killer for boob lovers. Even with her sister around, she'd find an opening to tempt me with 'breast mounting,' and it wasn't just frustrating, it was unbearable. Sandwiched between marshmallow-like tits, I was in heaven with tit-fucking, getting my balls drained dry until I was completely spent.
