The jogger's sister...

Emma jogged slowly away from her freshly seeded victim. Jogging a little awkwardly she tried to work the wedgie out of her butt crack. Her loose running pants had less room now that she had a cock.

Mentally replaying how she fucked a baby into her last piece of ass, she was distracted and stumbled on some gravel. Coming to a stop next to the trail Emma was bent over with the wedgie deeper into her crack.

"Oh my God! Are you OK?" a chipper voice asked. "Let me help you to the bench." The youthful voice practically said in her ear. Emma felt a hot sweaty body push into her left side. The stranger took her left hand to support her.

Everything seemed perfectly normal until Emma felt a small but strong hand, palming her plump very round butt cheek.

"I run here all the time. There's a bench just off the running path over here..." the youthful voice innocently suggested.

Craning her head to look at the speaker Emma felt her cock head flex involuntarily. The tingling energy of desire returning to radiate through her body. The girl looked like a younger version of the bitch she had just knocked up.

Tight body glistening with sweat. Except for her shoes a tiny running thong, a minimal sports bra seemed to barely contain her bulging C-cup tits, and a headband was all she wore.

"Sounds good!" Emma said with a grin. Arching her back to thrust out her boobs and booty. Pushing her wide hips into the girl's hand still clutching her ass. "Can you keep holding me, I must have pulled a muscle...". The bench was blocked from view by the tree line. Emma felt her cock sending images of blasting cum into her helper's womb.

"You look just like a woman I jogged past earlier." Emma casually mentioned.

"Oh that's probably my sister! She and I run different speeds so we meet up later. I have plenty of time to help you..." the girl said as she continued exploring Emma's THICC flexing butt cheeks.
