It had been 4 years since thier fist night of passion. After finding out she was pregnant the mayor threatened to send him to the authorities. But erin was able to talk him out of it by telling him it was her doing. He agreed not to if nyanza takes responsibility.
Now nyanza his wife erin and their son adam live on nyanzas farm. One night while adam was at his grandfathers erin and nyanza were feeling in the mood. nyanza lies on the bed while erin teases him with a strip tease. Nyanza cant help but pant at the sight. Erin has grown into a beutiful young woman with a petite rear C cup breasts. before they start erin pulls out from a drawer an herb she says its a fertility herb and asks what he thinks about having another kid. Insead of saying anything he grabs her by the waist and kisses her.
Feeling delighted by the responce she eats the herb. Erin gets onthe bed on all fours nyanza behind her slowly inserts himself both moaning having little alone time lately left them pent up. starting a steady rythm he leans over and grabs her breasts messaging her nipples.
Erin moans even loader from the stimulation not wanting him to be left out she reaches under herself and starts messaging his balls. Nyanza leans back up grabs her hips and doubles his speed leaving Erin a moaning mess. after a few minutes he feels himself getting close and starts putting force into his hips trying to breech her cervix. luckily it opens enough for him to enter just in time for his climax. Feeling her womb full of cum sets of erins own. After coming down from their orgasms the drift off to sleep hoping the herb worked. Luckily for them the herb worked causing her ovaries to release 2 eggs. Durring the night her eggs were fertilized making her pregnant with twins.
