"Like mother like daughter I see."
I turned to see her mother standing a few feet away, still stark naked. She watched as her daughter carried on trying to swallow me whole.
"No darling," she said, "not like that. You need some variation. Use your tongue on his balls, lick the tip, it's very sensitive and you will drive him mad. You don't have to swallow his whole length to get him off. Let me show you."
To my amazement, and soon to my delight, she stepped forward and eased Ann's head away from my cock, before dropping to her knees alongside her daughter. She cupped my balls in one hand then bending forwards she licked my entire length from balls to tip before taking just the end between her teeth, nipping gently, making me groan in pure ecstasy. Then, she took me in to her mouth, not as far as I had seen her just before, but her tongue never stopped moving as she did it and I groaned again.
She pulled her head away, holding the base of my cock with one hand, squeezing gently.
"Try again like that. He won't take long now, and I wouldn't want to deprive you of all that young cum."
Ann took me in again, less frantic this time, her mother still holding my cock as she did so. This time she took it slower, licking and nipping as she took me deeper and deeper, her mother's hand still firmly clenched around the base.
"See, with your hand there, he can't go too deep unless you let him." Judith removed her hand and I felt Ann's replacing it. Judith stood and moved behind me, pressing her body against my back, reaching around to cup my balls in one hand, pinching a nipple with the other. I pushed even harder into Ann's mouth as she released her hand and gripped my thighs, nails digging in as she sucked me deeper. I felt myself coming hard and called out to warn her, but she held on and I emptied myself into her mouth. I groaned yet again as I kept on coming, thrusting into Ann's mouth, pushing back against Judith's naked body behind me, her hands squeezing my cheeks as Ann's raked my thighs.
Eventually I stopped. Ann sat back on her knees, wide eyed, cum dripping from her mouth.
"Don't waste that dear, swallow," said her mother, reaching around me to scoop some from her daughters mouth onto her finger, then hungrily licking it clean.
Helping her daughter to her feet, she said,
"You did quite well, Harry. Most boys your age having their first blow job would shoot the lot within seconds."
She took her daughter's hands, then kissed her on the cheek, licking the last traces of cum as she did so.
"Mum!" said Ann. "Don't do that. It was bad enough you joining in like that."
Her mother just laughed, then looked at me.
"I don't think Harry minded..."
I hadn't. To be honest, I had softened a bit when I first heard her voice, but after that I just went with the flow. Ann was gorgeous enough, but her Mum had everything she had and it was all there in plain sight. Feeling her erect nipples press into me as I came in her daughter's mouth was, well amazing.
