from Zwischen den Jahren
Catrin Striebeck making out with a guy as the guy helps her undress, Catrin laying back in bed in her bra. We then see the guy having vigorous sex with her from behind, her breasts coming into view as she reaches her arm back at times. From Zwischen den Jahren (AKA End of the Season).
Catrin Striebeck rolling over on top of a guy in bed, talking to him for a bit before making out with him as he lifts her shirt off over her head to reveal her breasts before she presses them against his chest. From Zwischen den Jahren.
