Slipping under the sheets, John's gaze transfixed on his girlfriend's cock, nipples sliding across the fabric only further stimulating him, he slides his lips over her wood.
Jen's eyes shoot open as she gasps and turns back over onto her back, dragging John along for the ride. Throwing the sheets off and seeing somebody her head is telling her is John deep-throating her... cock? The rush from the surprise as well as the sensation of John's lips and tongue pleasuring her jolts back the memory of the previous night. Her boobs growing, The despair she felt at the discovery of her dick, but then John's acceptance and the fun they had afterward. The wave of emotions washed over her all at once, and the stimulation John was giving her now pushed her over the edge, and she erupted a wave of cum into John's mouth.

"you have a point I guess..." John trailed off, sliding out of the bed. Standing together in the bedroom, both of them were about 5ft 11in; Jen barely taller than John now.
Jen picked up one of John's robes and went out into the living room to turn on the news: They weren't alone, the news was talking about a wave of people reporting similar incidents all over town. The news focused on some of the more violent scenarios, an not-insignificant number of people were murdered by their presumed partners upon discovery of their dicks. While feeling sad for those people, Jen thought back to John's reaction of acceptance, and a tear formed in her eye. She'll protect him through this, no matter what.
After John prepared a delicious breakfast, the couple decided to...
