"Hey what are you doing Jason?" She asked a little shocked at his boldness.
"I just thought I should untie the bows of your bikini bottoms so they didn't get oil on them either." He explained hoping she wouldn't turn her head and catch him out.
"Ok but no funny business mister is that clear?" Lisa said to him.
"Yes mom that's clear." But Jason had other ideas in his head.
Lisa Collins was now lying in front of her son Jason as naked as the day she was born, ok she was face down on the lounger but she was still butt naked. Jason stood above her and unseen by her he began jerking his cock slowly not wanting to do it too fast and spoiling everything and cum all over her without getting to have his throbbing member deep inside her bald pussy. He stood there mesmerized by her tight little butt cheeks that he had forgot all about rubbing on the suntan oil on his mom's legs.
"Hey mister what happened to you oiling my legs up so I don't get sunburn on them?" She asked half turning round and catching him beside her naked jerking his cock.
"What the fuck are you doing?" Lisa blurted out.
Before she got to say anything else her son had straddled her thighs and pushed on her face down again on the lounger. He then leaned forward onto her and slipping himself between her thighs he rubbed his manhood up and down her ass crack oiling up his cock. A few seconds later he spread her legs a little wider with his own so he had enough room to get his cock lined up with his mom's pussy. As he rubbed his cock up and down her pussy lips she tried bucking him off her but to no avail. Her pleas went unheard to as her son had only one thing on his mind and that was to bury his throbbing penis as far inside his mom's pussy as he could possibly get it.
As he thrust his cock between her ass cheeks he oiled himself up enough spread her legs a little wider with his own and line his dick up with his mom's cunt. He thrust himself at her pussy and slid part of the way in with her shouting abuse at him and pleading for him not to do this to her but he still wasn't listening to her and pulled almost all the way out before ploughing himself all the way in till he was balls deep inside his mom's pussy.
"No, oh god no Jason please get off me I'm your mom not whore." Lisa cried out and try as she may to knock him off her.
