After all Marks efforts in satisfying Carol it seemed wrong to send him home so late so we offered him the spare room which he accepted.
After saying goodnight we climbed into bed and I was still horny as hell but Carol had had enough cock and drink for her to note off quickly despite my wandering hands so had to content myself with a hand job.
