My sister's boyfriend has been overseas for a long time now. They have weekly skype dates, but she hasn't been very happy with them lately. She didn't even get to cum during this one. I thought I could rub one out while she was busy on skype but she catches me jerking off and we talk. She and I are both really sexually frustrated and lonely. I am SO embarrassed that she saw me jerking my dick, but she says it's not a big deal. I am still really turned on and she looks so good in her bra and panties. I suggest that since neither of us has been with anyone in a long time and haven't been able to get off, maybe we could just look at each other and get off together? I mean, it wouldn't be that weird to just look at each other and masturbate together. It looks so good, though, and eventually, I ask her if I can touch her pussy. She says yes, and touches me too. I make her cum so hard with my fingers and she returns the favor by letting me cum all over her tits! It's so awkward now. Will anything else happen again???
