yes

He steps back and has a good look at his sister, then turns to his mother, takes the camera and passes it to his sister. “your turn Mum. The brat can take the pics while I test your nightie”

He moves his mother to the middle of the room and stands in front of her. He watches her face as she looks on at him with happy acceptance. He reaches forward to straight to her breasts, he spends a min just groping them, feeling the heavy weight as he lifts them through her nightie.

“I am thinking of having Tina dress in a satin blouse with no bra, if I bet her to let me such her nipple through the blouse will it feel good?” asked Tom. He didn’t wait for an answer he just bent his head down and latched onto one of his mothers hard nipples poking into her nightie , as he mumbled “I need to test”

He stood their suckling on his mums tits through her nightie as his sister took photos, all in the guise of testing clothes so he can decide what they wear on Saturday.

After a couple of mins, he steps back and sees the wet patch around her nipples and the satin glued to her tits. He leans back down to her left breast and with his right hand slips the right strap off the nightie off her shoulders. His hand pushes down and grabs a hold of his mother naked breast.

His face slides across and for latches onto her exposed nipple. After 10 secs “whoops sweetie, nightie is out the way, you better finish the test so we can go to bed.”

Tom pulls his face away and as he does gently bites down on her erect nipple, it stretches out as he pulls away until: POP.

The nipple breaks free and he watches her tit jiggle slightly as it drops down.

“Sorry it was an accident” states Tom as he reaches up to take the other strap down allowing the nightie to full to the floor. His mother is now just standing there in her panties. For the first time he sees the front they have beautiful little butterflies and flowers stitched into them. The contrast to the green satin makes it look like they are flying on a field of grass.

As he steps back and watches he sees it is nearly midnight. He takes the camera from his sister knowing he has pushed it far enough.

“Ok, lets quickly finish. Mum can you arch you back.” She does fully displaying her tits in all their glory to her son.

“Now turn around and slide down your panties” his eyes fully focused though the lens as he captures his mother taking the last bit of clothing of on camera. She steps out of them and stands back up.

“ok naked pic time, Lisa stand with mum around each others backs. Arch you back and stick out your butts. Turn back and look over your shoulders at me. Perfect. Now turn around for a pic of the front, Great, lean your heads together big smiles, fantastic, now I need you to shift your out legs and open them up a bit, just a bit more. Wow perfect. One last thing slide your arms up each others backs, now reach around and grab each others breasts and give it a squeeze like it is a big game and you are giggling over it. Perfect.”

“Ok sweetie, that is enough time for bed”

“sure Mum.” He walks forward and gives her a peck on the cheek. He reaches around and gives a firm slap to her arse ‘Just remembered I never gave my birthday spankings”

Ana laughs “it is the other way sweetie, you're meant to get the spankings, not give them out”

He moves over to his sister as she is bending down to grab her clothes and gives her a hard spank as well “My bad” Tom laughs, “night brat”
