The Situation
So the night was going great. I head to the bedroom she follows. We start making out / fooling around. I start pleasuring her. Shes loving it she undoes my belt drops the pants and does a little pleasing not much. I keep doing what i'm doing and i still get nothing outta her. Not even a tug for 10 secs straight. Whats the deal. Then her friend calls her and she has to leave. This probably went on for 30 mins or so.

and i'm left with Blue balls hurting me.

The Question
How the hell do I get the transition for her to actually start giving me what i'm giving her?!

OR am I doing something really wrong for her not passing the favor?

Let me know. Should i let her start the whole pleasuring thing or do i keep doing what im doing?

Ps.
Does this happen a lot? as in you give pleasure but none in return? !

Jokerex

Maybe she is just unexperienced and doesn't know what to do? Anyway, in such situation you can just tell her: touch it (in whispering way) or just take her hand and place it on your cock. As from my expierience, afer that girls stopped resisting.

Or, what is worse, you might have forgotten about building good SPAM (I assume you haven't fucked her before) and she didn'n feel comfortable and safe. Maybe, in the light of expected intercourse, last resist before fucking occured (how does it name in English?) and you didn't disarm it in time.

I personally think that it's creepy to do this. I think it makes things much more open and comfortable if you don't create an SPAM where you both feel like you're doing something wrong or need to whisper. I'd just tell her exactly what you'd like her to do to you - that's what you wish she'd do for you isn't it? Failing that, then yeah, put her hand on your dick and stop doing whatever you're doing to her and she'll know that it's her turn to please you.
