All this while the conversation was in whispers and Sheela confessed that the aunt was not aware of the “special services” that I gave Sheela. I a...sured her not to worry and asked her whether Sheela herself wanted a massage once I got through with the aunt. Sheela nodded her assent. She added that this aunt was quite notorious when she was younger and was rumored to have several affairs in her time.I smiled but stuck a businesslike attitude and asked Sheela to get the aunt ready. Internally,. What the hell had I just done?I slept fitfully that night, tossing and turning, images of my sister’s face and body never leaving my mind. I didn’t know what had happened, but I felt awful about it - my sister was an innocent, and I’d used her nudism to get off. I’d perverted her lifestyle, used her as a sex object ... I was scum, and I hated myself for it.The next morning, I woke up with an erection. Cursing myself, I resisted the urge to jerk off - I knew that if I did, I’d just end up. As they sat down on the couch my wife had already pulled out a bottle of wine and two glasses as she poured our guest a glass I plugged in my headphones to listen to what the women were talking about. Over the next hour the two women talked gossip, life, and a variety of other topics. The two sat next to each other my wife staring into Megan’s eyes while Megan sipped her fourth glass of wine. The topic went to that of fantasies as Megan said she had always wanted to have a fling with someone. I hear the water turn off and pretend to be reading when the door opens and I watch my best friend and roommate exit the bathroom and head to his bunk. The bulge under the towel moving left and right as he walks past me is not hard to notice. He opens his wall locker and reaches for his underwear and sets them on his bed. He undoes the towel at his waist to finish drying off and I quietly inhale as his cock swings freely. He hangs his towel on his locker and turns to pick up his underwear to.
