She went up the 2 small flights of stairs & I couldn't resist looking at her tight little ass! She peerd through the letterbox & said it seemed ok but... she wanted her partner to see it first. "Will you be in around 5?" she asked, I replied "yes". "We will pop around then" she said before leaving.5pm came & I must admit I was looking forward to seeing her again. My buzzer rang again & I went to the door. There she was, in tight tee shirt & jeans WOW! what a difference - my cock started to stir.. "Nothing really," Becky responded. "I think he just wanted to tease you for some reason." Oh," said Kristina. She might have probed a little deeper but the teenager was distracted by hearing her cousins giving their mother a blow by blow description of Kristina's declaration of love for Rick and them kissing. Kristina fled to her bedroom in embarrassment and humiliation. Now she was the subject of family gossip. "What next?" she uttered in frustration.Kristina plopped down her books on her. Not thinking much about it I began to rub her ass,causing her to moan softly as she sucked on my cock. God she was good,she would bring me to the edge and start teasing me, keeping me fromcumming which was very different then any of the others I had beenwith. My hand had worked it way back to her ass and then I felt not theback of a pad but a bulge that shouldn't have been there!Almost on the verge of my orgasm I quickly put my fingers into herpanties and was totally shock to feel a penis! I. I could tell that my gf was starting to get turned on and not long after they started dancing, they excused themselves to the bathroom. I got another drink and after about 10 minutes, they appeared, rather flush in the face. My gf came up and whispered in my ear that we were invited back to her room for an "after party." We got our coats and walked with her to her room. She poured a few glasses of champagne and immediately began to undress. My gf and I quickly followed suit and before I.
