Lots of things.
Starting with the anticipation of the meet, then when you arrive and you actually find that you do fancy her. Next, following her upstairs especially if she's in heels and stockings with good legs or her arse is in front of you. Then DFK, undressing feeling those gorgeous tits her lips and tongue on your bare cock, licking her clit to orgasm, to any sex position, especially as you slide in for the first time. Finally the cum action, especially if it's cim with eye contact and she shows it to you.
Now, let me load up AW and get booking......
