The moment Michael's door clicked shut, Betty's eyes finally fluttered open. She had sensed what Michael was smearing on her even before he started applying it to her breasts.
Initially, Betty might have thought it was just arousal fluid or vaginal secretion, but as it touched her breasts, she sniffed subtly a few times. Clutching the sheets tightly, she recognized the distinct musky scent of male hormones all too well.
After Michael left for the bathroom, presumably to clean up, Betty slid her hand into her pajama pants. As she felt the contours of her own body, her fingers reached her vagina. Pulling her hand out, she sniffed it and then let it fall limply onto the mattress, drained of all strength.
A single tear rolled down from her eye, tracing her cheek before soaking into the sheets. She had confirmed that the substance smeared on her was indeed Michael's semen, and he had even pushed the initial load inside her.
