It was a dark blue color so I couldn't see through, but I imagined how beautiful she must look behind it. I continued to stroke my cock and sniff her ...anties, then I suddenly heard a moan come from behind the shower curtain.Could me mother be masturbating too? I thought. She started moaning faster and louder now. That only motivated me to stroke my cock faster and sniff her panties more. "Uh, uh, uh uh, yes, yes" was all I could hear from the other side of the curtain. I could tell she was. "Oh my god your huge" really I'm not like a porn star or something but I do have a big dick. I just answered "chicken?" liking the fact that she had little room to go verbally without loosing face. Jen: "uh I haven't ... um"me: "ok I'll leave now, you can chicken out or follow me" I though if I let this go on it might turn into k**die chatter and I like using the element of curiosity. I moved my fingers between tess's legs touching about where I suspected her clit was and softly moving back. We kissed many times, she responded well then I took off her blouse and caressed her boobs over the bras, she started to moan, I gave her long tongue kisses same time I removed her bras to show her bare boobs. They were small but round and firm, I held one by one in my hand then sucking them until the nipples became hard, she was enjoying much.I then asked her when her next period is due, she said next Tuesday (in two days) I also asked her if she is regular with her periods and if she has ever. Not thinking too much I went back to the sofa and pressed play on my movie. About 10 min later she came in wearing nothing but some white cotton panties and an over sized shirt she got from my closet. She came in with a little strut that iv never seen before with a seductive smirk on her face that made my dick start to grow. She sat down right next to me and started to cuddle up against me next thing I know she takes my arm and puts its right around her and drags it till its almost at her.
