Fun With Babysitting - Part2

Last week i posted my story, this is a follow-up.

Small recap, me 17, gf 15, she's a sitter for some families, one of them has a dau of 13.
She busted me and gf making out and a bit more.

It took some time before my gf asked me over to that family again, she was afraid the dau (Anne) would have told about us and we would get in trouble. Luckily she didn't tell and no problems. Anne would sometimes come down and ask my gf about sex and when i would be around again. So, after a few times babysitting, my gf asked me to come by which i gladly did.

I was making out with my gf, kissing hard, my hand under her skirt, when Anne jumped next to her on the couch. 'I wanna watch, so please don't stop' was all she said.
I looked at my gf, she looked at me and pulled me closer to kiss again.
We kissed, i continued fingering and now and then we looked at Anne who watched us.
It was hot n weird at the same time.
My gf moved ontop of me, still kissing, when she started taking her top off and pushing her titties in my face. kiss, suck them, she said and i did, feeling kinda horny that Anne was watching.
As i was playing with my gfs titties as she moved her hips on me (still pants on) as a soft moan was coming from the side. Anne was again playing with herself as she watched.
Want to see his dick Anne, my gf than asked and before i knew, my gf moved aside and opened my pants to take it out. She started jerking me as we kissed, my hands on my gfs titties playing, sometimes watching Anne who was watching us, me, my dick.

Are you gonna come, Anne asked?
Are you, i asked her?
Almost, she said.
Want to show us how you come, i asked?
and without me meaning to, she stood up, pulled her pj-pants down and got back on the couch, spreading her legs as she was playing.
It was hot watching her, and my gf was hot watching her too, as her pace was irregular, which i was happy about cause i might have already shot watching Anne.
My gf urged her on.. come on Anne, show us how you come. Play with your nice little pussy.
Some more moans and then Anne closed her eyes, her body shaking.
As she regained she looked at us, please, make him come, show me, she said in a soft voice.
My gf worked up her pace and quickly i shot my load, partly on my pants and belly.
i kissed my gf and then fell back on the couch, looking back and forth at Anne and my gf.

Then stood up, put on her pj-pants, kissed me and gf on our cheeks, whispered thank you, and left the room. I looked at my gf and she only asked me to lick her to orgasm, which i did quickly.
