I went round to the other end and saw his own good sized cock was still hard inside his panties. I pulled it out and went to work returning the favour... It didn't take very long. He came in my mouth after just a few licks and sucks. There wasn't much cum either given the weekend of sex he'd just had. I didn't spill a drop as I tucked his cock back into his panties whilst he finished cleaning Mistress. "Thank You Chris" I said - I loved what he'd done, from the amazing way he'd given me my first. "Not yet, Sissy, cum with me. I'm almost…" Trista attempted to finish her sentence but instead started grinding harder, lifting her ass from the bed.Just as their pussies began erupting, the sisters took hold of each other's hands pulling each other harder into the other.Terrana began squirting into her sister's cunt as Trista was right in the height of her explosion. Feeling the sensations of her sister, Trista jerked her hips hard into Terrana's clit in her final thrust of release.Exhausted. . globs of my saliva came oozing out of the ‘O’ shaped gag and onto my breasts.Jeremy licked the saliva that was on my tits.“You know slut, you are the most gullible person I know. I had always wanted to make you my slave when I saw you in my first day of school. I can’t believe, that behind your stern and strict demeanour, you are actually such a stupid and trusting teacher, who can easily be manipulated into a sex slave. Now straddle me.”He pushed my legs apart and I slowly lowered my pussy. They asked me if I wanted something to drink and I had a glass of ice tea.I started to walk around looking at some of the toys when granny came up and asked that I could try anything I wanted here.I started to feel a little tired from the drink don't know why so I asked if I could lie down somewhere.They took me into a back room and undressed me told me I would feel so much better this way.Cary the one I was kissing in the car came up and we started again but she took my hands and tied them to.
