No No Daughter Swimsuits

My 12 yo stepdaughter is developing extremely lady like. Can't touch this!
She stays with me everyother weekend so it seems like she has grown every time I see her. So sexy, hot, and built for being too young. I fight to

keep my thoughts clean. But last weekend while shopping for

swimsuits she was seductively showing me way too much skin and asking

arousing questions that you'd expect her to only ask a girlfriend.

How does body part x look in this? Do you like this and that? Is this

too big, small, tight, loose, etc? She had me tugging and pulling to help her with her suits. Unintentional feels landed here and there in the process. She was revealing herself to my hands and eyes. A few suits were close to naked giving me more than I could handle; wanting to rub

my tip between her fuzzy pronounced lips while my tongue and lips

trace her pointy hard nips and tits; just for starters. Instead my

discipline commanded that even though nudity is natural I won't buy you thong, sheer, micro, too small or tight swimsuits and they must have padding to cover your finer parts. I reminded her that she

is growing so just one suit today. Ideas of buying a few of the sexiest ones for the apartment only sent pulsating vibes through my hard erect cock. I was hitting new arousal heights and my concentration turned to mush. On the ride home we disscussed in detail the different suits. I was hurting and couldn't wait to get into less restrictive clothing. As soon as we got inside I went straight to the bedroom, stripped, and walked out in only a pair of cotton boxers. My snake wanted to pop right through the opening so I turned them at the waist which created what resembled a tent. Her eyes opened wide and bright following me to the couch without commenting. She acted calm and normal as I seat in hopes my dick wouldn't pop out. Maybe I should have worn briefs but I wanted something new and more risque. We put the tv on and chatted until she went back to talking about the suits and her body. The sexual tensions were increasing so I tickled, grabbed, lifted and carried her to the bed where we playfully wrestled and fell asleep. In the morning I awoke in spoon position with my rock hard dick pressing into her tight ass. It felt awesome, then I realized I wasn't dreaming. I had to get up and out of bed but struggled because she was sleeping on my arm. She moved some but I remained quiet and hoped she was asleep. In the bathroom I tried to keep noises down as I massaged with precum and masturbed till eruption and a yelp. After showering I left in a towel only while contemplating an accidental drop until released that would be moving things too fast. Our relationship is growing and as we

become more aware of one another emotionally, physically, and

mentally, there is questions of our sexual attraction, developements,

and sitiuations.
If I could afford, I'd rent a bigger apartment which would help with temptations.
I confess to being anxious for next weekend's visit or just horny in reliving our last adventures?

I want to do it again and maybe a little more? Maybe we

can shop for panties, bra, and a nighty.
