I was standing there, eyes closed, my stiff staff sliding in and out of her and getting progressively closer to a climax when a voice behind me said, “Wow! It sure smells like sex in here. Have you guys been going at it all afternoon?”
As much as it startled me, I never missed a stroke, even when Sarah’s hand began to caress the cheek of my ass.
Her mom said, “For goodness sakes, Sarah, can’t you see we’re busy. Go away and wait your turn.”
Now Sarah was feeling my balls as my pile-driving ass pounded my rod deep into her mother. Her soft, warm hand on my tender testicles was all it took. I unloaded the meager remainder of my semen into Ruth’s welcoming snatch at the same moment she went down the roadway to the village of orgasmic bliss. Slowly I withdrew my rapidly softening tool from Ruth’s cunt while it was still dripping cum, and made my way to the bathroom.
It took me quite a few minutes to clean up and regain my composure. By the time I got back to the bedroom, both of them were in bed and covered up to their chins with the sheet. Sarah threw back the cover, revealing part of her bare breasts, and patted the mattress, inviting me in.
“We’re waiting for you. Mom says she has only done it three times and you still owe her one more to catch up to me.”
“Good luck to her! I don’t think I could get another hard-on if Miss America promised me a blow job.”
“Don’t you worry about a thing; you just lie there and enjoy what we’re going to do to you. Mom and I are experts at this.”
They were better than experts, but it still took them the better part of an hour to get my attention. It finally ended up with Ruth straddling my groin, sitting on my reasonably hard penis, riding me like a bucking bronco, and Sarah spanning my face with my tongue lodged in her sweet pussy.
I experienced my third, Ruth finally got her fourth, and Sarah started a whole new series.
Well anyway, all of that was almost seven months ago, so Todd didn’t know that the girls moved in with me. He went to a friend’s house close to campus for Thanksgiving, and then spent Christmas with his mother in New Jersey, so I still haven’t told him I got married. He’s coming here for spring break, and the girls are looking forward to seeing him again. I wonder how he’s going to feel about having sex with his new stepmother, Sarah, or his new step-grandmother, Ruth.
