I must have moaned of something because she looked up immediately. She didn't say anything, but she stepped up to the tub and pulled the c...rtain open. There I was with a major boner and my sister's best friend staring at it. At first she seemed pissed at me but she looked me in the eye and gave me a weird look. "Does your sister know what a pervert you are?" she asked. "You are were getting off listening to me pee weren't you?" I was in shock; I had no. - Did you like my kiss, I hope?- Oh, is it a kiss? – Martha blushed and pulled me to her.It may sound vulgar but as soon as my lips joined with hers my hands started caressing her shoulders, arms, back…- You’re so hot!!!The woman undid the upper button of the blouse with a smile. My fingers slid to her bust and a minute later I was kissing her nipples. And in five more minutes we were on the bed both naked. I was pawing her half-dried but very attractive pussy with one hand and my spare hand. "You know, you're rather pretty," her voice turned sultry and seductive. She kissed my cheek and her breasts pressed up against me. I felt myself getting hornier and hornier. I groaned loudly with annoyance as I grew an erection. "What the fuck is that?" Alexia asked, as she felt something hard dig into her side. She stepped back and both she and Lisa stared back in shock. "Well, well, well, looks like some one has been hiding a secret." Alexia lifted up my skirt quickly before I had the chance. Work tomorrow. I must go, Andrew."They both stood up."Thank you, Andrew," she said. "It's been a super evening and that curry was delicious."She reached up and pulled his head down for a sweet kiss. His arms went gently round her."Thank you for coming, Katrina. I enjoyed every minute of it."For a moment they both stayed motionless looking into each other's eyes and then without a word kissed softly again.Andrew saw her out to her car and waved her off. Both were very happy.The following evening.
