I obviously was day dreaming as I didn't hear the door go and I was interupted by a load cough, Gemma had caught me wanking in her shower, what could ... do but look her in the eyes and continue to stroke my rigid shaft. She now didn't know where to look but said that she heard me last night outside her room and asked if I'd seen anything, without breaking my rhythm I said that I'd seen her facesitting Dave and I saw her cum whilst she rode his cock. With that she dropped her robe and revealed. I was very turned on, but my desire to be fucked hadn’t drowned out my fear of getting caught.“Don’t worry. We will be really quiet, okay?” he said softly, his urgency growing.I could only nod in agreement because his fingers were doing wonderful things to my asshole. After a short while, he lay down next to me and aimed his cock at my waiting hole.“Are you ready for me, sweetie?” he asked, gently.“Yes,” I moaned. Almost immediately I could feel him applying some pressure as he pushed the head. Betty's body was doing strange things she couldn't possibly understand. The girl screamed, her pussy going into tremors of need. That feeling in her shitter was changing, becoming something good, something incredibly warm and wanted. But still it wasn't what she needed--a good hard fucking in the pussy. She needed a prick fucking back and forth in her cunt, rubbing against her clit. There were two perfectly good cocks in that basement now and neither of them were in her pussy!Betty felt. "I know you know." I know you know I know." Shut up and kiss me." Yes ma'am, one kiss coming up" That's not all that's coming up, holy cow that's outrageous it looks like ababy arm holding an apple and wearing a French cuff." Mmmmph " MMMMMMMMMMMAAAAAAHHHHHHHHHHHHHAAHAHAHAHHHHHHHHHHHHHH!!!!!!!!!"
