CHAPTER 23

Mom then rolled over onto her front, "Doc, would you be a sweetheart and rub some lotion into my back?" she asked. I didn't need to be asked again as I quickly grabbed up the bottle and climbed over her legs. I shot a dollop onto her lower back and ran my hands up her spine, gliding underneath the bikini ties and reaching her shoulders. My hands slid to her ribcage and I managed to cover some of her side boob.

"That feels pretty good." she said. I got off of her legs and was now kneeling at her side, I squirted another jet of lotion onto her lower back and then began massaging it into her, soon sliding my hands over her perfectly round ass.

Bobbie was watching with keen interest as I squeezed Mom's cheeks and made sure to cover the whole area. I covered the backs of her thighs to and moved to her hips. I could feel her lift herself off the ground a little and force her ass into the air. Her skin was now glistening, but I continued to focus on her ass. After a few short moments I had completely forgotten that Bobbie was there.

She flicked her dirty blonde hair over her shoulder to gain my attention, revealing her now strapless summer dress had dropped a little down her chest. Her puffy pink nipple was beginning to peek out over the top and her big green eyes were staring deep into mine.

I thought about the time she asked me to tickle her, like I had tickled Mom. She was so ready to receive whatever came with that, but I refused to cross that line. I refused then, and I could refuse again. Despite her round adorable face, and her willingness to be apart of the relationship I shared with Mom.

And Mom seemed to be on board, getting her to tie her to the bed whilst wearing the sexiest lingerie I had ever seen. Bobbie must have know what was going on, and Mom must know that Bobbie knows.

I was getting so confused with what was happening inside of my head, I hadn't noticed my erection. My hands were running rampant over Mom's ass and Bobbie was creeping closer, pretty soon she was going to notice.

"I want to help," my sister said. She picked up the lotion and was about to squirt some onto Mom's back, when she rolled over.

"Mommy's back is fine now honey, maybe you should top up my front." she said. I couldn't believe it, without a seconds pause Bobbie squirted the tanning lotion onto Mom's chest and began slowly rubbing it into her, her hands slipped quickly underneath Mom's bikini and was now kneading her breasts. I watched in dumbstruck awe, as the love of my life was having her breasts massaged by my little sister.

There was clearly more to the Mother and Daughter relationship than I had thought, the Mother and Son relationship was in a place I never dreamed it would be, I can only imagine what Bobbie is learning from Mom.

Bobbie continued to massage her breasts, the bikini was now pulled up towards Mom's neck as Bobbie's fingers drew circles around Mom's hard nipples. Mom looked over at me and opened her legs, she was turned on in a way I had never seen before and my cock was screaming out in agony of being restricted by my joggers.

I placed a hand on Mom's knee and let it slid down her thigh, I teased her for a moment by letting my finger tips brush against her clitoris. The blue bikini fabric looked to be dry, but I was willing to bet that it wasn't the same on the inside.

Mom's pelvis came off the ground after my tease, and her hand had gone around behind Bobbie. I teased her again as Bobbie began to pinch her nipples, she continued to play with Mom's breasts seemingly in a daze.

I pulled at the string on Mom's hip and her bikini bottoms fell apart, her vagina was almost on complete show as my finger lightly rubbed against the tip of her clitoris. Mom's hand was now under Bobbie's dress and firmly on her ass. Her other hand came up to her chest and cupped one of her breasts. Bobbie looked at it for a moment before leaning forward and licking it.

I glanced around at the surrounding houses, our garden fences were pretty tall and didn't have anywhere for anyone to peek in. I then dropped my head between Mom's legs and lashed at her with my tongue. Her legs bucked a little as she had to bite down onto her lip to keep from moaning. She now held Bobbie's head as my sister sucked on her nipple.

I couldn't believe what we were doing, but I continued my part and began tickling Mom's clitoris with my tongue. I slipped down a little to her vagina, lapping up some of her juice before going back to where I was.

Bobbie now had a firm hand on Mom's breasts and was going back and fourth between the pair, sucking the nipple of each, licking the nipples and even lightly biting on the nipples. Mom was in a frenzy, her hips were going up and down, all there was for me to do now was stay there with my tongue out and she was doing the rest.

I held onto her thighs as she slid her pussy up and down my face, I wanted more than anything to free my cock and ram it inside of her. But this was already way out in the deep end of perverse. I couldn't imagine what would happen had I began fucking Mom with Bobbie clinging to her nipple. I decided that my time would come later, and focussed on giving Mom the orgasm.

I hadn't long to wait, as she could no longer hold back the vocals and let loose a desperate moan as she furiously began rubbing her clitoris, spraying her cum all over my face.

She let out a loud gasp of relief as she slumped to the ground, Bobbie looked at me before crawling to me, she came up to my face and her tongue rolled out of her mouth. She licked the side of my cheek sending a shiver down my body.

"Mommy you taste nice." she said smiling at our lifeless Mother. She turned her head back to me and smiled, before coming in close for a kiss. I must have been lost in thought as our lips met, it was a peck at first, but much like the first time I had shared a kiss with Mom, a peck on the lips became three pecks. Followed by a long kiss, my hand moved around to Bobbie's back as I supported her. I pushed myself forward as she fell backward, I lowered her softly to the ground as we continued to kiss.

Our kiss broke on several occasions, but her hand kept coming up and pulling my head back down towards hers. My free hand was on her hip, sliding between there and her leg. I stole a quick glance towards Mom who was watching through a glazed expression.

Bobbie's dress had both ridden up and down at the same time, her pink nipple on full display as well as her bare legs and little vagina was free in the breeze.

I kissed her again before dropping my head into her neck, I pecked her a couple of times and she said nothing. She hadn't said a word since first rubbing lotion onto Mom. I kissed her collar bone a couple of times as my hand came back to her hip, and then up to her ribs. I dropped lower again and kissed one of her erect nipples. Her breasts were developing and would one day be as beautiful as Mom's, but right now I appreciated her pink and puffy tits.

My hand was now sliding back down her body, I rested my fingers on her pubic bone and then she did what Mom had done earlier, she brought her hips up.

Mom was now moving towards her, she kissed Bobbie on the forehead and their eyes locked, I looked at the pair of them as my middle finger slowly approached her clitoris. I took a moments pause, allowing one of them to tell me to stop, but neither one did. Bobbie instead reached up and pulled Mom's head towards her, they're lips collided as my middle finger hit the clitoris.

Bobbie gasped as I began a slow stroke, it was enough to get any juices she had going. I ran my finger down to her vagina and realised that she was having no issue with her juices, she was almost dripping.

I collected a little of it on my finger and gained a little speed, instead of stroking I was now lightly rubbing small circles around her clitoris, her feet were making fists as she lifted her pelvis and hips off the ground. She looked down at me as I began rubbing her, I got a little harder and before long her heavy breathing became panting. She was red in the face and it wasn't from the sun, I was getting her close to her very first orgasm and she knew it.

Mom knew it too, and couldn't resist sliding her hand between her own legs and vigorously rubbing her own clitoris.

"Doc, I feel–" Bobbie tried talking, but her eyes were almost rolling into the back of her head. She threw her head back and her legs straightened, her body was off the ground as she let out this low level groan, while she was arched I had began rubbing her harder, and with each shake of my wrist a new sound came out of her throat. I was looking to see if she was a squirter like Mom, but she didn't appear to be, yet.

She then dropped down to the ground and curled up as Mom reached her climax, she dropped down with Bobbie as the liquid squirted out of her and rained down onto Bobbie's dress. Both them lay there for a few moments, curled up and holding one another.

I looked at them both, realising this family was never going to be the same after this. Bobbie had now been introduced to what me and Mom were keeping so quiet, and as much as I loved Bobbie, I wasn't sure how we could keep this from Dad.

Not that I really cared about him, but if he ever found out what was happening, Mom would be arrested and fuck knows what would happen to Bobbie and I. We'd be separated for sure though.

As my rock hard erection slowly began to realise it was going to have to wait for some satisfaction, I began to think about Faye. I wasn't sure if she would tell Paige anything, but the night away would be good for her. I'd send her an email later to check in on her, but in the mean time I was starting to feel a little hungry.

"So Mom, what's for dinner?" I asked.
