Step daughters/Asexual/1st Wednesday/play here/see
You have plenty of games you'd like to try with the girls and maybe it would be safer to at least start with Sandra in her room ... but you actually feel like toying with Masha too.
You come sit next to Masha and brings Sandra with you. You put Sandra on your laps and can hear Masha sigh.
You, with a silent voice to Sandra: "Let's try to not make to much noise ok? Masha is trying to watch the tv".
Sandra, in your arms facing you nods very seriously.
You blow gently on her hair and she starts to giggle as discretely as possible. You tickle a bit and she is even less discrete.
Masha sighs. Sandra makes a guilty face and stops, turning herself to watch the tv. You start stroking her hair and neck gently but she has a hard time remaining still and she replaces herself a lot on your lap until ...
Sandra: "What is that?" she asks, moving her ass on one of your leg and putting her hand on the bulge on your pant.
You: "Well you know, it is what boys have between their legs, a penis." You conveniently leave out the part about being hard and believe you are done with the explanation. Boys were you wrong!
Sandra seems puzzled and follows your penis' shape with her hands and when you risk a look toward Masha to see if she noticed she seemed hypnotized by the shape under your jean.
You, now surprised and getting more excited as time passes: "You do know what is a penis, right?"
Sandra applying herself to repeat a new word: "A pee-nus?"
You are surprised Sandra does not know that already ... but Masha seems just as lost as her little sister.
