Go with Alison

You leave the bar with Alison, and travel on the tube to her house.

The trip would have been uneventful, but as the tube was crowded you had to stand, as did Alison. You were standing behind her and were leaning over her shoulder to continue with small talk over the noise of the train. Of course in that position you had a really good view down her blouse at her magnificent cleavage. This of course got you hard.

As the train swayed, you kept bumping into Alison. As you cock was now full and hard, it was bumping against her gorgeous ass. And as the journey continued, you felt Alison pushing back against you, grinding herself on your boner.

You were smiling inside thinking about what you and this sexy minx were going to "eat" for dinner when you got to her house.
