Since the days had been warmer, we had occasionally played this game in our lovemaking where Heather put on a blindfold, of the type travellers use on airliners to get to sleep. She seemed to find it exciting, anonymous love. I used the fact that she couldn't see me to move around her body and surprise her with my tongue or fingers or prick on some unexpected part of her naked body.
On this particular night, Sean had come around. He was maudlin because his relationship was going through a rocky patch. Heather went off to bed earlier, leaving Sean and I alone. We had had a bit to drink, and he was clearly in no fit state to drive home. I offered him a bed for the night, and realised I had an idea which I wanted to try out. He seemed keen. I asked him to give me fifteen minutes, then come naked to our bedroom.
When I got to bed, she was relaxed, half asleep, but responsive to my touches. I suggested the blindfold, and talked Heather into it. We took off her clothes, pulled back the covers, and I began kissing her all over her body. She lay back and enjoyed the caresses. When I kissed her lips, I could tell she had been thinking sexy thoughts. Her lips were soft and responsive.
I paused and moved stealthily to the door. Sean was standing there in the nude, grinning sheepishly, and holding onto one big erection. I motioned him in. In the room, I climbed onto the bed and straddled Heather, kissing her belly and moving down her thighs. Sean stood for a while at her side, letting his eyes acclimatise to the dark, then he reached out and began playing with her nipple. When he used his other hand to play with her other nipple, I could feel her tense. I looked up from kissing the inside of her thigh to see her touch his hand, run her fingers along, feeling its length and texture, and obviously trying to work something out. She quietly called my name in the electric atmosphere, and I quietly answered.
At that point Heather knew that those were not my hands on her breasts, making her nipples so hard. I decided to force the issue, and made a dive for her pussy, kissing her mound hard, and urging her legs apart. She was initially reluctant, then let me in. My tongue started its work on her clitoris, and she opened up. I was keen to see what was happening, so I had to position myself for the best view. She kept on playing with Sean's hands at first, letting him finger her hard little nipples. At some point, he bent over, and teased her left nipple with his lips and tongue. Then it happened. Her left hand snaked out and ran up the inside of his thigh. She played with the hairs on his leg, then ran up (higher than where my penis would be, because he is taller) first to his balls, which she fondled, then to his prick.
