"Yes." Allyson repeated after Lisa. Gabrielle probably hadn't heard her sister, but they were both enjoying it. Gasping loudly, Allyson ground her hips against the younger Turpin between her thighs. If this time didnt work to get her pregnant, she didn't think she would have the guts to do it again!

Allyson closed her eyes, muttering something about being close to orgasm. But Lisa didn't care!
