In the shadowy back alley, she progressively accelerated her blowjob pace, in proportion to her arousing, which was rising as much as he fingered her ass. It was a bit late but Benjamin still questioned her.
"Are you alright with my finger in your butthole?"
She nodded strongly without releasing his dick and her face looked like he hadn't even needed to ask. Now having her express permission, he focused on that part more. This wasn't a selfless decision since he had seen how she was intensifying her sucking when he did so. He wet a second finger and used two of them to increase his attack power. This was a correct decision because she soon changed the way she blew him, from minimal movements and lazy tonguing to sucking him strongly.
However, it was different from any other head he had gotten in the past. She didn't move back and forth much and instead focused all her mouth power on sucking him, maximizing her suction power as much as possible. It was like his cock was gelatin and she was trying to aspirate it, to constantly slurp every bit inside her mouth. Her lips were distorted to the front of her mouth in a very lewd manner, proof of how intensively she was going at it. This was a new feeling for Benjamin who couldn't help groaning in pleasure at the stimulation. It felt like his member was being aspirated by a wet and warm vacuum machine, stimulating him in ways unknown so far. She looked pleased with his reaction and went on with her sucking, slowly moving her tongue around his glans for increased pleasure.
It felt incredible and he wasn't able to continue focusing on his fingering, simply enjoying what his mother was doing to him. It didn't take long before he was ready to come.
"It feels amazing Mom. Don't stop, I'm almost there... Coming!"
His waist jerked and his penis' head rested on her tongue, blasting his sperm in her cavity with a shout of satisfaction. His mother closed her eyes in appreciation and greedily aspirated anything that he released until he was completely spent. She immediately switched to strongly sucking any remaining sperm inside his shaft, forcefully draining his urethra. Once this was done, she went back to her lazy tonguing, as if to congratulate herself for a job well done.
"Wow Mom, that was awesome. You're so good at this."
She finally released his dick and laughed with a proud smile.
"Hehehe."
She looked at his still-hard cock and added.
"You are also amazing in a different way, still so hard like that."
She caressed his dick lovingly but before they began anything else, Benjamin said.
"Let's move to the back seats, we don't have enough space here."
She nodded in agreement and both of them exited the car from their side, removed their clothes in the fortunately empty alley, and entered again from the back seats. Now in front of each other and ready to go all the way, both hesitated, unsure how to start this. Benjamin remembered her specific taste he learned about after the poker game and knew what she most likely wished for.
"Mom?"
She had her gaze focused on his penis and was clearly at maximum arousal, her cunt juices flowing out on the car seats. She looked up at him when he called her but wavered and didn't give him an immediate reply. She looked down at his sex again and panted hard, probably having some very arousing ideas but hesitating to speak of them out loud. Eventually, she sighed and told him.
"Leave it all to mommy, dear. I will make you feel the best."
Judging by her face, this wasn't what she really wanted to do. When she tried to make him lie down on the seats, he stopped her and asked again.
"What do you really want to do, Mom?"
She trembled at his question and looked at his face. He was smiling as if to suggest he knew everything and her heart beat harder under her precious' son's stare. Seeing that his words weren't without effect, he gave her one more push.
"For you, Mom, I will do anything. Anything you want, whatever it is."
She gasped and shivered. She looked at his tool once more and into his eyes one last time before finally giving in and accepting his persuasion.
"You made me so horny and now you're saying something like that. You better take responsibility for your words."
While blushing hard, she laid on her back across the seats, her large boobs jiggling in accordance with her movements. She lifted her legs until they were high up and used her hands to pull them towards her body, now parallel to her torso. She then looked at him and declared.
"T-this is how Mom likes it. Put your body on top of mine and come into me strongly. Do me hard, as hard as you can."
She was now panting hard, a good amount of shame mixed with her extremely lecherous expression. Her trimmed twat was releasing fluids like never before, almost like a miniature fountain. Considering how women were supposed to be dominant in bed, her shame made a lot of sense. As for Benjamin, seeing his mother take such an erotic pose aroused him immensely and his dick twitched in anticipation. Today was the day he would fuck his Mom and he wasn't going to hold back, just like she wanted.
He jumped on her, his body enveloping hers. Without any more delay, he adjusted his aim with a hand and pushed his hips forward, penetrating her all the way in one go. He felt her warm and wet flesh opening to give room to his cock, his tool scratching against her inner walls and soon reaching her cervix, bumping strongly against it. Feeling his penis inside her, his mother was in ecstasy.
"Aaahhh! My first dick after so long! My baby, my son is back home inside mama! You're so big, darling!"
Her pussy enveloped him ardently, her flesh contracting around his member. Finally, he was having sex with his mom and the mere thought of it pushed his penis to swell inside her. It felt incredible and he might have come very quickly if he hadn't gotten a release just before. His mother, on the other hand, was barely holding on. He moved his waist up to send another strong thrust into her and this one was too much for her to take. She cummed hard with a loud shout of happiness, her toes curling up once again in pleasure and her pussy gushing juices around his dick.
